How many electrons would Boron with a +2 charge have?

irina [24]

5 electrons

Boron atomic number 5 has five electrons in its ground state.

Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form.

Explanation:

The atomic number gives the number of protons. Protons which have a positive charge are balanced by an equal number of electrons in a neutral atom.

Boron number 5 has five protons and therefore as a neutral atom also has five electrons.

Boron has an electron configuration of

1s22s22p1

The most stable electron configuration for Boron is

1s2

+ 3 charges. By losing three electrons Boron can achieve the stable electron structure of Helium

A serving of soup contains 5.0 g of fat, 20.0 g of carbohydrates, and 3.0 g of protein. Determine how many kilocalories (kcal) a

marta [7]

Answer: The amount of kilocalories contained in the given serving of soup is 0.137 kCal

Explanation:

As per the USDA:

Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.

We are given

Mass of fat in the soup serving = 5.0 g

Mass of carbohydrates in the soup serving = 20.0 g

Mass of protein in the soup serving = 3.0 g

Conversion factor used: 1 kCal = 1000 Cal

Applying unitary method:

For Fat:

1 gram of fat provides 9 calories

So, 5.0 gram of fat will provide = $\frac{9}{1}\times 5.0=45Cal=0.045kCal$

For Carbohydrates:

1 gram of carbohydrates provides 4 calories

So, 20.0 gram of carbohydrates will provide = $\frac{4}{1}\times 20.0=80Cal=0.080kCal$

For Proteins:

1 gram of proteins provides 4 calories

So, 3.0 gram of fat will provide = $\frac{4}{1}\times 3=12Cal=0.012kCal$

Total kilocalories per serving = [0.045 + 0.080 + 0.012] kCal = 0.137 kCal

Hence, the amount of kilocalories contained in the given serving of soup is 0.137 kCal

Which metal ions can be precipitated out of solution as chlorides?a. Ag+, Hg2+, Co2+b. Cu2+, Cd2+, Bi3+ c. Ag+, Hg22+, Pb2+ d. N

Fudgin [204]

Answer:

Explanation:

In the qualitative analysis of metal salts , we see that in group I , metal chlorides are precipitated out . It is so because their metal chlorides are insoluble in water .

In this group following metal ions are present

Ag+,
