1. A 36.0-gram sample of formaldehyde (CH20) contains 14.4 grams of carbon. How
1 answer:
Answer:
14.4 / 36.0 × 86.0 = 34.4 g
Explanation:
Given data:
Mass of carbon in 36 g of formaldehyde = 14.4 g
Mass of carbon in 86.0 g of formaldehyde = ?
Solution:
We will use cross multiplication to solve this problem.
14.4 / 36.0 = x/ 86.0
x = mass of carbon in 86.0 g of formaldehyde
14.4 / 36.0 = x/ 86.0
x = 14.4 / 36.0 × 86.0
x = 34.4 g

Answer:
cl2 - 1 bond
HCl.- 1 bond
N2 - 3 bond
o2 - 2 bond
- Cl requires one electron to complete it's octave so it share it's one electron with other chlorine and make a single covalent bond
- H has one electron and Cl requires one so both form one single bond
- N requires 3 electrons so it form 3 bonds with other N
- oxygen requires 2 electrons so it forms 2 bond with other oxygen
maybe 1+8 (4+548) 4/6 4+4
The answer is A hopefully it is ok ✅
