Explanation:

Covalent bonds are defined as the bonds which are formed by the sharing of electrons between the atoms. They are usually formed by non-metals.

The number of covalent bonds are predicted by the number of valence electrons.

Elements belonging to Period 3 and above will form covalent bonds same as the number of valence electron because of the presence of d-orbitals.

Elements belonging to period 2 will form covalent bonds = (8 - number of valence electrons)

For the given elements:

Bromine is the 35th element which belong to period 4. The electronic configuration of $1s^22s^22p^63s^23p^63d^{10}4s^24p^5$

This element has 7 valence electrons and will form 7 covalent bonds.

Hydrogen is the 1st element which belong to period 1. The electronic configuration of 1s^1

This element has 1 valence electrons and will form 1 covalent bond.

Chlorine is the 17th element which belong to period 3. The electronic configuration of 1s^22s^22p^63s^23p^5

This element has 7 valence electrons and will form 7 covalent bonds.

Germanium is the 32nd element which belong to period 4. The electronic configuration of $1s^22s^22p^63s^23p^63d^{10}4s^24p^2$

This element has 4 valence electrons and will form 4 covalent bonds.

Sulfur is the 16th element which belong to period 3. The electronic configuration of 1s^22s^22p^63s^23p^4

This element has 6 valence electrons and will form 6 covalent bonds.

Arsenic is the 33rd element which belong to period 4. The electronic configuration of $1s^22s^22p^63s^23p^63d^{10}4s^24p^3$

This element has 5 valence electrons and will form 5 covalent bonds.

Boron is the 5th element which belong to period 2. The electronic configuration of 1s^22s^22p^1

This element has 3 valence electrons. It will form (8 - 3) = 5 covalent bonds.

Silicon is the 14th element which belong to period 3. The electronic configuration of 1s^22s^22p^63s^23p^2

This element has 4 valence electrons and will form 4 covalent bonds.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
