Answer:
203 grams
Explanation:
The no. of moles of (6.3 x 10²⁴ molecules--Avagadros number) of NH₃ = (1.0 mol)(7.2 x 10²⁴ molecules)/(6.022 x 10²³ molecules) = 11.96 mol.
The no. of grams of NH₃ present = no. of moles x molar mass = (11.96 mol)(17.0 g/mol) = 203.3 g ≅ 203.0 g.
Answer:
limiting reactant
Explanation:
<em>The term that will be used to describe zinc in this case is </em><em>limiting reactant.</em>
A limiting reactant is a reactant that determines the amount of product formed in a chemical reaction. They are often stoichiometrically smaller of all the reactants in a reaction and once they are used up during, the reaction stops.
In this case, the zinc metal in the reaction is completely consumed, making the hydrochloric acid to be in excess. The zinc thus determines the amount of the products formed,
Answer:
Explanation:
Hello,
In this case, since the given undergoing chemical reaction is correctly balanced, the reaction quotient is computed as well as the equilibrium constant but in terms of the given concentrations that are:
In such a way, the reaction quotient turns out:
Taking into account that carbon is not included since it is solid.
Best regards.
Answer:
B
Explanation:
living things are not required to move
Answer:
1.54 atm
Explanation:
By Dalton's Law Of partial pressure,
Total Pressure = Sum of all partial pressures
So,P= P1 + P2 + P3
Therefore, P=0.23+0.42+0.89
=1.54 atm
