h = 3.0 a + 28.2
A pediatrician uses the model above to estimate the height h of a girl, in inches, in terms of the girl's age a, in years. Based on the model, what is the estimated height of a 2-year-old girl?

Answers

Answer:

h = 34.2 in

Explanation:

h = 3.0a + 28.2

h = height of a girl.

a = age of a girl.

h = 3.0a + 28.2

h = 3.0(2) + 28.2

h = 6 + 28.2

h = 34.2

The estimated height of a 2-year-old girl is 34.2 in.

Why do you think the mass of the carbon atom shown is 12 atomic mass units (amu)?

Answers

Answer:

The mass of Carbon-12 is exactly 12 amu. But, that is not the number that is reported in your periodic table. Carbon as it exists in nature is not all carbon-12. There is some small amount of carbon-13 and even traces of carbon-14 in there. The periodic table reports the average mass of the carbon as it is found in nature, not that of pure carbon-12. The average mass of carbon is slightly heaver than carbon-12, because of the slight amounts of those heaver isotopes of carbon in nature.

The formula of calcium chloride is CaCl2, what do those letters and numbers tell you about the compound calcium chloride?

Answers

Answer:

It is a compound made up of one Calclum atom and 2 Chloride atoms.

It comes from a synthesis based reaction:

Ca + Cl = CaCL2

The letters you see are the abbreviations of the elements taken from the periodic table of elements.

Explanation:

The formula of calcium chloride is CaCl2, the  letters  are the symbolic form of chemical compound and numbers are the total number of moles of the chemical compound.

What is a mole?

A mole is the single or the smallest form of any chemical compound or element and it can be in any member but the value of one mole will always be equal to the 2.303 × 10²³ of the carbon atom.

In CaCl2, the Ca is the symbol of calcium and Cl is the symbol of chlorine and the 2 Witten after Cl is the total number of moles attached with it which is making the whole chemical.

Therefore, formula of calcium chloride is CaCl2, the  letters  are the symbolic form of chemical compound and numbers are the total number of moles of the chemical compound.
