Answer:

A) pedigree chart tracks inherited traits from parents to offspring.

A pedigree chart is a diagram which depicts the occurrence of a particular phenotypic character being expressed from the parents to the offspring as the trait or character is inherited by the offspring from the parents. Therefore, on the basis of this information A pedigree chart tracks inherited traits from parents to offspring is the correct option.

How does the level of carbon dioxide affect the level of water vapor in the atmosphere?

gtnhenbr [62]

Explanation:

“This new data set shows that as surface temperature increases, so does atmospheric humidity,” Dessler said. “Dumping greenhouse gases into the atmosphere makes the atmosphere more humid. And since water vapor is itself a greenhouse gas, the increase in humidity amplifies the warming from carbon dioxide."

In a cycle of copper experiment, a student first reacts a piece of copper metal with nitric acid to produce copper(II) nitrate (

LuckyWell [14K]

Answer:

0.631 grams is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment

Explanation:

The concentration of the solution is given by :

$[C]=\frac{\text{Moles of compound}}{\text{Volume of solution in Liters}}$

We have:

Concentration of copper (II) nitrate solution = $[Cu(NO_3)_2]=2.41 M$

The volume of solution = 4.12 mL

1 mL= 0.001 L

$4.12 mL= 4.12\times 0.001 L= 0.00412 L$

Moles of copper (II) nitrate in solution = n

$2.41=\frac{n}{0.00412 L}=0.0099292 mol$

Moles of copper (II) nitrate in solution = 0.0099292 mol

1 Mole of copper(II) nitrate has 1 mole of copper then 0.0099292 moles of copper(II) nitrate will have :

$1\times 0.0099292 mol= 0.0099292 \text{ mol of Cu}$

Mass of 0.0099292 moles of copper:

$=0.0099292 mol\times 63.55 g/mol=0.63100 g\approx 0.631 g$

This mass of copper present in the solution is the theoretical mass of copper present in the given copper(II) nitrate solution.

0.631 grams is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment

An atom of iron has the atomic number 26. This means that

Zanzabum

Answer:

Answer in explanation

Explanation:

An atom of iron having an atomic number of 26 means there are 26 protons in the nucleus of the iron atom. This also means that for an electrically neutral atom of iron, there are 26 electrons orbiting the nucleus of the iron atom.

Factually, this also means that the atom iron occupies the position of the 26th element on the periodic table. Going forward, we can also say that the proton number of the iron element is 26.
