Answer:
Metal is named first
Explanation:
Binary compounds:
The compounds which are made up of the atoms of only two elements are called binary compounds.
For example:
The following compounds are binary:
HCl
NaCl
HCl is binary because it is composed of only hydrogen and chlorine.
Sodium chloride is also binary compound composed of only two element hydrogen and chlorine.
When naming these compounds the name of metal or cation is written first and anion is written after the cation. The anions are non meals.
The anion name is end with suffix " ide".
such as sodium chloride.
Answer:
The correct option is (a).
Explanation:
We need to find the product of given numbers.
First number = 29.5
Second number = 240
Product of two numbers = 29.5 × 240
=
Zeroes from numerator and denominator get cancelled.
So,
Hence, the correct option is (a).
One mole of NaCl weighs 58.44 grams
Therefore 1L of one mole of NaCl contains 58.44 grams
1L of 0.2m NaCl contains 58.44x0.2 = 11.69grams
300mL of 0.2m NaCl contains 11.69x0.3 = 3.51 grams
