Answer:
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
Explanation:
The molecular weight of acetylene is 26.04 g/mol
Molecular weight of carbon is equal to 12.011 g/mol
Two carbon atom produces one acetylene molecule.
Thus, 2 * 12.011 g/mol of carbon is used to produce 26.04 g/mol of acetylene,
Amount of carbon required to produce 59.8 grams of acetylene
grams/mol
grams/mol of carbon is needed to react with hydrogen gas to produce 59.8 grams of acetylene (C2H2)
For the reaction to take place the energy of the reactants must reach to the energy level of the products:
we have 900 J in the reactants and 9000 J for the products so the reactants need 8100 J to reach to the value of energy of products (900 + 8100 = 9000)
So the correct answer is C. <span>The reaction absorbs 8100 J of energy from the surroundings as it proceeds. </span>
The realized niche may be less extensive.
Answer:
lol one time some random person came up to me one the street and screamed "theyre coming, hide!!!" i was sooo confused
Explanation:
If the resources run out and there is no way to get them all motors will have to be switched to solar or some other source.
