B, because that’s the simplified definition of accuracy
Answer:
136.5886g of NH3
Explanation:
N2 + 3H2 = 2NH3
The mass of the N2 = 4.01
3H2 has a 2/1 ratio
This means the mass of 3H2 is twice as much as N2.
NH3= 2*N2 = 2*4.01 = 8.02 of NH3
Then, by multiplying the mass by MX (17.031)
8.02*17.031=136.5886g can be produced. Round it if needed.
Answer: Pressure from when the mountain formed creates the sedimentary rock.
Explanation: it’s prob wrong but i’m taking the test rn and this is my best guess
mass of the gas = 10 g
<h3>Further explanation</h3>
<em>The law of conservation of mass :</em>
<em>In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.</em>
Reaction
mass before reaction=mass after reaction
Answer:
Explanation:
The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
