Notice that the chemical equation provides you with information about how many moles of each chemical species takes part in this reaction.
More specifically, you know that
1
mole of solid copper will react with
2
moles of silver nitrate to produce
1
mole of aqueous copper(II) nitrate and
2
moles of solid silver.
So, assuming that you have enough silver nitrate available to allow for all the sample of copper to react, you can expect the reaction to produce twice as many moles of solid silver than you have moles of solid copper taking part in the reaction.
Use the molar mass of copper to calculate how many moles you have in your sample
1.00
g
⋅
1 mole Cu
63.546
g
=
0.01574 moles Cu
According to the aforementioned mole ratio, the reaction will produce
0.01574

Finally, use the molar mass of silver to convert the number of moles to grams
Nuclear energy comes from splitting of Barium atom to form Krypton atom
Moles of phosphoric acid would be needed : 0.833
<h3>Further explanation</h3>
Given
15 grams of water
Required
moles of phosphoric acid
Solution
Reaction(decomposition) :
H3PO4 -> H2O + HPO3
mol water (H2O :
= mass : MW
= 15 g : 18 g/mol
= 0.833
From the equation, mol ratio H3PO4 = mol H2O = 1 : 1, so mol H3PO4 = 0.833
Answer:Balance. Acid+metal->salt+hydrogen.1 molecule od zinc contains 1 zinc atom.2 molecule of HCl contains 2 atoms hydrogen and 2 chlorine.1 molecule of Zncl2 contain one atom of zinc and two atom of chlorine.And two 2 atoms of hydrogen.
Explanation:
Sulfur trioxide (SO3) is a chemical compound that is a significant pollutant in gaseous form as it is involved in the production of acid rain.
Industrially, sulfur trioxide is an important precursor to sulfuric acid and is formed from the reaction between sulfur dioxide (SO2) and oxygen gas (O2) as shown in the chemical equation below.
