Answer: 5.1 gram
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of require = 1 mole of
Thus 0.41 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
Moles of HCl left = (0.55-0.41) = 0.14
Mass of left =
Thus 5.1 g of hydrochloric acid could be left over by the chemical reaction.
Answer:
Size and Mass of the Nucleus
Explanation:
Electrons have virtually no mass, but protons and neutrons have a lot of mass for their size. As a result, the nucleus has virtually all the mass of an atom. Given its great mass and tiny size, the nucleus is very dense.
Oxygen is a reactant in combustion and the concentration of oxygen is higher in pure oxygenthan it is in air.
<u>Answer:</u> The equilibrium concentration of chloride ions in the solution is 4.532 M
<u>Explanation:</u>
We are given:
Initial molarity of = 0.054 M
Initial molarity of HCl = 4.60 M
Equilibrium molarity of = 0.034 M
The chemical equation for the reaction of and HCl follows:
Or,
<u>Initial:</u> 0.054 4.60
<u>At eqllm:</u> 0.054-x 4.60-2x x 6x
Evaluating the value of 'x':
So, equilibrium concentration of = (4.60 - 2x) = [4.60 - 2(0.034)] = 4.532 M
Hence, the equilibrium concentration of chloride ions in the solution is 4.532 M
