Answer:
The answer to your question is given after the questions so I just explain how to get it.
Explanation:
a)
Get the molecular weight of Phosphoric acid
H₃PO₄ = (3 x 1) + (31 x 1) + (16 x 4)
= 3 + 31 + 64
= 98 g
98 g ----------------- 1 mol
0.045 g --------------- x
x = (0.045 x 1) / 98
x = 0.045 / 98
x = 0.00046 moles or 4.6 x 10 ⁻⁴
b)
Molarity = 
Molarity = 
Molarity = 0.0013 or 1.31 x 10⁻³
c)
Formula C₁V₁ = C₂V₂
V₁ = C₂V₂ / C₁
Substitution
V₁ = (0.0013)(1) / 0.01
Simplification and result
V₁ = 0.0013 / 0.1
V₁ = 0.13 l = 130 ml
Answer:it loses one electron
Explanation:
When it loses one electron it has a noble gas configuration
Answer:
This observation can be explained under the following reasons:
- High sodium content
- Lowered heat temperature
- Organic burn
Explanation:
High sodium content from the potato fluid causes the flame to turn yellow, as indicative of the presence of sodium (flame test).
The colour change could also be attributed to the drastic lowering of the burner heat. Finally, pure organics like wood and fats burn red, a would be the case with fluids from the boiled potatoes.
I hope this explanation was helpful.
The correct answer is c.
answer b is incorrect <span />
