Answer:
b. Mg & Cl
a. transferred
46
Explanation:
Ionic bonds form between metals and non-metals when electrons are transferred from one specie to another.
- The electrostatic attraction from the resulting ions forms the ionic bonds.
- A metal is electropositive and will readily donate electrons
- A non-metal is electronegative and will accept electrons.
- This creates two oppositely charge ions that attracts by means of ionic bonding.
Since Mg and Cl are the only metal - non-metal pair, and ionic bond will form between them.
2.
In the specie;
₄₇Ag¹⁺
47 is the atomic number of the element Ag.
The atomic number is the number of protons in an atom. For a specie in neutral state, the number of protons and electrons are the same.
- When an atom loses electron, it becomes positively charged.
- Here Ag has lost one electron and then, the number of electrons becomes 46.
- The number of protons is still 47
Answer:
P(H₂) = 807.2 torr
Explanation:
According to the Dalton law, the pressure of mixture of a gas is sum of the partial pressure of its mixing component gases.
P(total) = P1 + P2 + P3 +....
In given problem,
Total pressure is = 794 torr
Partial pressure of water = 13.2 torr
Partial pressure of hydrogen = ?
Solution:
P(total) = P(H₂O) + P(H₂)
P(H₂) = P(total) - P(H₂O)
P(H₂) = 794 torr - 13.2 torr
P(H₂) = 807.2 torr
