This is an example of the formation of Ionic compounds/bonds.
Answer:
I`m pretty sure it`s electrical tape.
Explanation:
<h2>Let us solve for it </h2>
Explanation:
Magnesium oxide
- It is MgO
- Its molecular mass is : 24 +16=40 g
- When MgO decomposes it forms = 3.54 g of oxygen gas
- when 40 g of MgO decomposes it forms = 16g of oxygen
- or we can say that :
- 16g of oxygen is produced when 40 g of MgO is decomposed .
- 1g of oxygen will be formed from =40/16g of MgO
- 3.54 g of oxygen will be formed = 40/16 x 3.54 =8.85g of MgO
Answer:
Total pressure = 759 mmHg
Explanation:
Given data:
Partial pressure of oxygen = 165 mmHg
Partial pressure of nitrogen = 594 mmHg
Total pressure = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Total pressure = P(O₂) + P(N₂)
Total pressure = 165 mmHg + 594 mmHg
Total pressure = 759 mmHg
