Answer:
0.72 g of the lower oxide gave 0.8 g of higher oxide when oxidised. ... Thus, 90g of lower oxide contains as much metal as 100g of higher oxide, i.e., 80g (given). Hence, 80g of metal combines with 10g of oxygen in the lower oxide and 20g of oxygen in the higher oxide.
Answer:
1) the carbon and hydrogen valence electrons
Explanation:
The lewis dot diagram illustrates how electrons are arranged round atoms in a molecule. The dots represents the;
1) the carbon and hydrogen valence electrons
mass = mol no. x molar mass
= 13.6 x 56+(3x14)+(9x16)
= 242g
