If you wanted to combine equal numbers of Na and Cl atoms in a flask, how much Cl would you have to add if you added 23g of NA?

Gwar [14]

Answer: The mass of chlorine atom required to combine is 35.5 grams.

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ .....(1)

For sodium:

Given mass of sodium = 23 g

Molar mass of sodium = 23 g/mol

Putting values in equation 1, we get:

$\text{Moles of sodium}=\frac{23g}{23g/mol}=1mol$

According to mole concept:

1 mole of an atom contains $6.022\times 10^{23}$ number of particles

So, 1 mole of sodium will contain = $(1\times 6.022\times 10^{23})=6.022\times 10^{23}$ number of atoms

Number of atoms of chlorine = Number of atoms of sodium = $6.022\times 10^{23}$ = 1 mole

Now, calculating the mass of chlorine required by using equation 1:

Moles of chlorine = 1 mole

Molar mass of chlorine = 35.5 g/mol

Putting values in equation 1, we get:

$1mol=\frac{\text{Mass of chlorine}}{35.5g/mol}\\\\\text{Mass of chlorine}=(1mol\times 35.5g/mol)=35.5g$

Hence, the mass of chlorine atom required to combine is 35.5 grams.

In a cross between two heterozygous tall and purple flowers (TtPp x TtPp), what would the

Goryan [66]

Answer:

9:3:3:1

Explanation:

This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).

According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:

TtPp - TP, Tp, tP, tp

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

T_P_ (tall, purple) = 9

T_pp (tall, white) = 3

ttP_ (short, purple) = 3

ttpp (short, white) = 1

Hence, the ratio of this cross is 9:3:3:1

The Oregon forest uses clearcutting to supply us with timber, a renewable resource we use to make lumber and paper. There are ma

Elis [28]

A con that is that eventually all of the forest will be destroyed.

Explanation:

The clearcutting method is a method that is often used around the world, so it is no wonder that this happens in Oregon as well. While the clearcutting manages to supply the market and even create surplus with timber and later its products, it also has several negatives about it. One major con about the clearcutting is that eventually all of the forest will be destroyed.

Because this method is based on mass cutting down of wood and not using any sustainable means, such as planting saplings on the places that were cut and cleared, it has terrible effects on the long run. Bit by bit, the forest will be cut in total, and because it was not renewed in meantime, the only thing that will be left behind will be barren and heavily eroded land.

This will cause big problem for the timber industry as they will have nothing to work with. The prices of the timber products will skyrocket because of this. The ecosystem will be totally destroyed. The land won't be used for agriculture because the soil is of poor quality and because of high rates of erosion.
