Given the equation: 2Na + 2H2O → 2NaOH + H2 Which substance in this equation is a binary compound?

Answers

Answer: In the following equation, H_2O is considered as a binary compound.

Explanation: A binary compound is considered as a compound having 2 elements only. In the following chemical equation:

2Na+2H_2O\rightarrow 2NaOH+H_2

There are 2 compounds present because compound is defined as the chemical combination of two or more elements in a fixed ratio.

In the equation, compounds are: H_2O and NaOH

H_2O consists of 2 elements which are hydrogen and oxygen and hence is considered as a binary compound.

NaOH consists of 3 elements which are sodium, hydrogen and oxygen and hence, cannot be considered as a binary compound.

A crucible contains 6.4 g of copper, Cu. How many moles does this amount contain? [Given: Cu=64]

Answers

Use this formula:
Mass = moles x RFM

(RFM = Relative Formula Mass, or the total mass of a substance or element for example Cu=64)

Rearrange the formula to find the number of moles
Moles = mass/RFM
           =6.4/64
           = 0.1
