To answer this question Kc of this reaction OR the conc of reactants nd products at equilibria is required.
Explanation:
Answer:
8 moles = 16 gm of H2 left over
Explanation:
The balanced equation is
2 H2 + O2 ===> 2 H2 O
20 g H2 = 20 g / 2 gm/mole = 10 moles of H2
32 g O2 = 32g / 32 g / mole = 1 mole O2
From the balanced equation, you can see each 2 moles of H2 requires 1 Mole of O2
you would need 20 moles of O 2 to react withe the 10 moles of H2
but you only have 1 mole of O2 so 8 moles of H2 will be left
I think this is true because..
technology negatively affects the environment by compromising human health and safety... endangering natural ecosystem and biodiversity... having a cumulative impact on global systems... and depleting natural resources. Technology positively affects the environment through the application of environmental science to solve problems caused by human environmental impact.
Risks to humans from environmental damage through technology include inhalation of dangerous chemicals in air pollution, contamination of water and food sources, and risk of infections and diseases through exposure to toxic wastes. Flora and fauna risk habitat loss or disruption and extinction of species through exposure to dangerous byproducts of technology. Greenhouse gases affect atmosphere and weather systems, causing global warming and chlorofluorocarbons that deplete the Earth's ozone layer. Technology consumes resources which are not necessarily renewable, including living resources, such as forests and populations of fish, and inanimate resources, such as natural chemicals and minerals.
Although technology damages the environment in many ways..it can also have the capability to limit or prevent damage using such environmental technologies such as recycling...the exploitation of renewable energy sources such as solar power and wind power... the purification of polluted air and water,and the treatment of sewage and factory wastes.. and the development and production of devices that promote energy conservation.....so this is why i think this is the answer! ☺
Hopefully this helped you!☺
Answer:
Molar volume, or volume of one mole of gas , depends on pressure and temperature, and is 22.4 liters - at 0 °C (273.15 K) and 1 atm (101325 Pa), or STP (Standard Temperature and Pressure), for every gas which behaves similarly to an ideal gas. The ideal gas molar volume increases to 24.0 liters as the temperature increases to 20 °C (at 1 atm).
