Answer:
C. Rate = k[H2]^2[O2]
Explanation:
Rate law only cares about REACTANTS. Since, rate law can only be determined experimentally, I am assuming the given reaction mechanism is elementary reaction from which we can write the rate law.
Only H2 and O2 are part of rate law since they are reactants and also the coefficient in front of H2 goes as exponent on rate law to indicate the order of H2 in the reaction.
Rate= k [H2]^2 [O2]
Answer:
C. CO2 exists in relatively high concentrations.
Explanation:
From the available options:
A. CO2 molecules are highly symmetrical.
B. CO2 has a low molar mass.
C. CO2 exists in relatively high concentrations.
D. CO2 is formed in the combustion of fossil fuels.
<em>The focus on CO2 as far as global warming is concerned is not because It has a high global warming potential but because of its relatively high concentration in the atmosphere as a result of both natural and anthropological activities.</em>
The correct option is C.
Based on distance to the nearest water well, the drilling site that would pose the least risk of methane contamination would be the one farthest away from the water well.
Methane is a gas that is known to escape from the ground and rise up into the atmosphere. If the drilling site is too close to the water well, there is a greater risk that the methane could contaminate the water.
The atmosphere is the air that surrounds us. It is a mixture of gases, including nitrogen, oxygen, and carbon dioxide. The atmosphere protects us from the Sun's ultraviolet radiation and from the cold of space. It also contains the Earth's weather, which is caused by the Sun's energy.

2.5 % w/v ( that means we have 2.5 grams of solute in 100 mL <span>solution )
1.00 mL = 1000 mL therefore:
2.5 g ------------- 100 mL
?? --------------- 1000 mL
1000 x 2.5 / 100 => 25.0 g of NaCl</span>
Answer:
10
Explanation:
The 5 will multiply the subscript 2 on the K atoms making it 10
