<u>Answer:</u> The number of carbon, hydrogen and oxygen atoms on the left side of the reaction are 12, 28 and 38 respectively
<u>Explanation:</u>
In a chemical equation, the chemical species are termed as reactants or products.
Reactants are defined as the species which react in the reaction and are written on the left side of the reaction arrow.
Products are defined as the species which are produced in the reaction and are written on the right side of the reaction arrow.
For the given chemical equation:
On the reactant side:
Number of carbon atoms = (6 × 2) = 12
Number of hydrogen atoms = (14 × 2) = 28
Number of oxygen atoms = (2 × 19) = 38
Hence, the number of carbon, hydrogen and oxygen atoms on the left side of the reaction are 12, 28 and 38 respectively
Answer:
H2O is the formula for water.
Answer:
i.e. mass of 1 mole of glucose, C6H12O6 = (6 × 12.01 + 12 × 1.01 + 6 × 16.00) g = 180.18 g (using atomic weight data to 2 decimals) 1 mole of carbon atoms weighs 12.01 g and there are 6 moles of C atoms in 1 mole of glucose, so the mass of carbon in 1 mole of glucose = 6 × 12.01 g = 72.06 g.
Answer:
Sodium oxide
Magnesium oxide
Explanation:
Because both of the oxides are bases
Answer:
37.3g
Explanation:
Formula of the compound:
FeCl₃
Number of chloride ions = 4.13 x 10²³ ions
First find the number of moles in this ions;
6.02 x 10²³ ions are contained in 1 mole of a substance
4.13 x 10²³ ions contains 
= 0.69mole chloride ions
Now;
3 mole of chloride ions are contained in 1 mole of FeCl₃
0.69 mole of chloride ions will contain 
= 0.23mole of FeCl₃
To find the mass;
Mass of FeCl₃ = number of moles x molar mass
molar mass of FeCl₃ = 55.8 + 3(35.5) = 162.3g/mol
Mass of FeCl₃ = 0.23 x 162.3 = 37.3g
