Answer:
b, c and d (last three options)
Explanation:
It can't be the first one because:
On the left hand side there is one of everything and then on the right, ther is one zinc, two chloride and 2 hydrogen atoms. It is unbalanced
Second one:
there are 8 carbons on both sides, 20 hydrogens on both sides and 26 oxygen on both sides. It is balanced
Third
1 copper on both sides, 2 hydrogens on both sides and 1 oxygen on both sides. It is balanced
Fourth
4 silver on both sides and 2 oxygens on both sides
Answer:
elastic potential energy which is also called spring energy.
Copper(I) sulfate, also known as cuprous sulfate and dicopper sulfate, is the chemical compound with the chemical formula Cu2SO4 and a molar mass of 223.15 So its "Cu2s"
<u>Answer:</u> The mass of carbon monoxide required is 1.094 kg
<u>Explanation:</u>
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
......(1)
Given mass of iron (III) oxide = 2.08 kg = 2080 g (Conversion factor: 1 kg = 1000 g)
Molar mass of iron (III) oxide = 159.69 g/mol
Plugging values in equation 1:
The given chemical equation follows:
By the stoichiometry of the reaction:
If 1 mole of iron (III) oxide reacts with 3 moles of CO
So, 13.02 moles of iron (III) oxide will react with = of CO
Molar mass of CO = 28.01 g/mol
Plugging values in equation 1:
Hence, the mass of carbon monoxide required is 1.094 kg
