![]() It should be a trivial task now to extend the calculations to mass-mass calculations, in which we start with a mass of some substance and end with the mass of another substance in the chemical reaction. How many grams of N 2 are needed to produce 2.17 mol of NH 3 when reacted according to this chemical equation?ģ0.4 g (Note: here we go from a product to a reactant, showing that mole-mass problems can begin and end with any substance in the chemical equation.) Now, using the molar mass of NH 3, which is 17.03 g/mol, we get: Start by using the balanced chemical equation to convert to moles of another substance and then use its molar mass to determine the mass of the final substance. The conversions are the same, but they are applied in a different order. ![]() ![]() How many grams of NH 3 will be produced when 33.9 mol of H 2 are reacted according to this chemical equation? The steps are the same but are performed in reverse order. How many moles of Al 2O 3 will be produced when 23.9 g of H 2O are reacted according to this chemical equation?ĢAlCl 3 + 3H 2O(ℓ) → Al 2O 3 + 6HCl(g) AnswerĪ variation of the mole-mass calculation is to start with an amount in moles and then determine an amount of another substance in grams. The last digit in our final answer is slightly different because of rounding differences, but the answer is essentially the same. From the balanced chemical equation, we construct a conversion factor between the number of moles of AlCl 3 and the number of moles of HCl:Īpplying this conversion factor to the quantity of AlCl 3, we get:Īlternatively, we could have done this in one line: Now we can use this quantity to determine the number of moles of HCl that will form. The molar mass of AlCl 3 is 133.33 g/mol, which we have to invert to get the appropriate conversion factor: We will do this in two steps: convert the mass of AlCl 3 to moles and then use the balanced chemical equation to find the number of moles of HCl formed. How many moles of HCl will be produced when 249 g of AlCl 3 are reacted according to this chemical equation?ĢAlCl 3 + 3H 2O(ℓ) → Al 2O 3 + 6HCl(g) Solution Sometimes the answer may be slightly different from doing it one step at a time because of rounding of the intermediate answers, but the final answers should be effectively the same. The units still cancel appropriately, and we get the same numerical answer in the end. However, it is mathematically equivalent to perform the two calculations sequentially on one line: In this last example, we did the calculation in two steps. So, we will get 1.159 mol of AlCl 3 if we react 123.2 g of Cl 2. Using this conversion factor with the molar quantity we calculated above, we get: The numbers in the conversion factor come from the coefficients in the balanced chemical equation: Now that we have the quantity in moles, we can use the balanced chemical equation to construct a conversion factor that relates the number of moles of Cl 2 to the number of moles of AlCl 3. We must invert this fraction so that the units cancel properly: The molar mass of Cl 2 (which we get from the atomic mass of Cl from the periodic table) is 70.90 g/mol. We know how to do this by simply using the molar mass of Cl 2 as a conversion factor. So to use the balanced chemical equation to relate an amount of Cl 2 to an amount of AlCl 3, we need to convert the given amount of Cl 2 into moles. How can we determine how many moles of AlCl 3 we will get when the reaction is complete? First and foremost, chemical equations are not balanced in terms of grams they are balanced in terms of moles. We can add that conversion factor as another step in a calculation to make a mole-mass calculation, where we start with a given number of moles of a substance and calculate the mass of another substance involved in the chemical equation, or vice versa.įor example, suppose we have the balanced chemical equation: Recall that the molar mass can be determined from a chemical formula and used as a conversion factor. Mole-mole calculations are not the only type of calculations that can be performed using balanced chemical equations. From a given mass of a substance, calculate the mass of another substance involved using the balanced chemical equation.From a given mass of a substance, calculate the moles of another substance involved using the balanced chemical equation.From a given number of moles of a substance, calculate the mass of another substance involved using the balanced chemical equation. ![]() How can you limit the damage to yourself and others-especially if you're in the latter category, and your work entails the likelihood of similar footage still to come? Still, suppose you went against your better instincts and watched it anyway, or were professionally obligated to. There is growing recognition that the same is true for those of us not engaging directly with victims and survivors: Storytelling in all forms is built precisely on not needing to meet someone in the flesh to empathize with them, to experience their suffering, fear and sorrow as yours. The British Medical Association describes vicarious trauma as "the process of change resulting from empathetic engagement with trauma survivors." It notes that "anyone who engages empathetically with survivors of traumatic incidents, torture, and material relating to their trauma, is potentially affected, including doctors and other health professionals." This isn't to say a single viewing of the footage will irreparably scar you-in fact, it's repeated exposure that carries the worst of the risk-but it will be, at the very least, far more unsettling than you probably bargained for. Every time you feel your heartbeat accelerating during a tense scene in a thriller, or jump when a dark figure rushes the screen, you're having a vicarious experience-and it can be as impactful as anything you are a part of, in real life. Huge swathes of culture-especially visual culture-is premised on our ability to viscerally experience violence indirectly. Thirdly, and as importantly, just because you're not at the scene and not in any immediate risk, this does not mean that you will not be affected. By looking through the killer's helmet camera, you are adopting his gaze, and actively participating in this indignity. If you want to know more about the victims, wait for their life stories to emerge. He was determined to humiliate them, to make them look like targets in a video game. Tarrant not only brutally brought this moment forward for dozens of innocent people, who had so many more years to live and so much more than him to give to their families, communities and to the country they made their home. Secondly, it is difficult to imagine a more intimate moment in any person's life than dying. There's plenty to be said for simply declining to oblige their desire for notoriety. Whatever false modesty Tarrant might profess in the tedious manifesto ascribed to him, a quality shared universally by terrorists of all ilk is the desire to stand out from the crowd, to be seen-if only by themselves-as heroes and possibly martyrs. The very fact terrorists exploit people's interest in dramatic events should caution you against typing in that search string, and certainly against sharing it with others.įirstly, by doing so you'd be playing up to the narcissism of someone who couldn't come up with any more adequate way to generate renown than to massacre innocent people. (I'm looking at you, Google and YouTube-not to mention Facebook, which hosted the live stream to begin with.) And you don't even need to be on 8chan to stumble on the footage: Search engines' predictive search will actively encourage you to browse for it when you type a related term. You don't need to be an 8chan denizen to be tempted by firsthand footage of an event dominating the news cycle, just as most people probably wouldn't look away if they came by the scene of an attack-or even a particularly bad accident-in real life. A small minority of us might be scanning the footage in desperate hope to establish the whereabouts of our loved ones.īut plenty of people are today looking at the Christchurch video for no real good reason-just because the draw of the drama and the apparent safety of viewing it from miles away, behind a computer screen. Some of us, like journalists and police, are professionally obliged to view distressing imagery to try to discern valuable new information, whether for investigation purposes or to better inform debate. Dozens of copies of what appears to be footage from a helmet-mounted camera are circulating on the darker corners of the internet and are being persistently posted on more mainstream platforms such as YouTube, Twitter and Facebook, which don't always manage to catch the video before it goes up. ![]() ![]() ![]() Horrific videos like the one posted by the Christchurch mosque shooting suspect Brenton Tarrant are geared to appeal to the morbidly curious, and appeal it did. integration with the 'streamer mode' module: IP geolocation data can be displayed in the OBS's text source. integration with the 'map' module: IP geolocation data is displayed on the world map. displays the stranger's approximate location (city/region/country), ISP, and whether they use a cellular network. uses the IP geolocation service to get the information about that IP address. determines the stranger's IP address used for WebRTC connection. coomeet free: displaying the stranger's country, bot recognition and volume control. ome.tv, chatruletka, minichat, chatrulez: displaying IP geolocation data in the chat area. ★ a minimalistic mode that includes only essential features: ★ Consider supporting our indie extension: ★ This is an entirely free, open-source project, but it evolves only because people like you support its indie development on Patreon.
