a sort of cell division that outcomes in two girl cells each having indistinguishable number and sort of chromosomes from the parent core, average of conventional tissue development.

Answer:

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

Mitosis is also the basis for healing wounds and fighting off invading pathogens that cause sickness. Certain organisms lose millions of cells per day as part of their normal function. Mitosis allows old cells to be replaced by new ones, ensuring an army of fully functioning cells.

victus00 [196]

Answer is: +113.
Nihonium is a chemical element with symbol Nh and atomic number 113. It has 113 protons (positive electric charge of +1). Protons, beside neutrons (neutral charge), are in the nucleus of every atom. Because only protons in nucleus have charge, charge of element-113 is +113.

D) The same number of each type of atom will always be present before and after a chemical reaction takes place.

Mass is never created or lost in a chemical reaction, so the atoms of each element must stay balanced.

Convert 3.2 moles of ch4 to number of molecules

REY [17]

Answer: 1.93 x 10^24 molecules

Explanation:

CH4 is the chemical formula for methane, the first member of the alkane family.

Based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 molecule

So, 1 mole of CH4 = 6.02 x 10^23 molecules

3.2 moles of CH4 = Z

To get the value of Z, cross multiply:

(Z x 1 mole) = (6.02 x 10^23 molecule x 3.2 moles)

Z•mole = 19.26 x 10^23 molecules•mole

Divide both sides by 1 mole

Z•mole / 1 mole = 19.26 x 10^23 molecules•mole/ 1mole

Z = 19.26 x 10^23 molecules

Place Z in standard form

Z = 1.93 x 10^24 molecules

Thus, 3.2 moles of ch4 has 1.93 x 10^24 molecules

What is the molar solubility of aucl3 (ksp = 3. 2 x 10-23) in a 0. 013 m solution of magnesium chloride (a soluble salt)?

Inessa [10]

The molar solubility of AuCl₃ in a 0.013 M solution of magnesium chloride is 1.81×10⁻²⁸M.

The solubility product constant, Ksp, is the equilibrium constant for a solid substance dissolving in an aqueous solution. And for the AuCl₃, Ksp will be written as: Ksp = [Au³⁺][Cl⁻]³

Let the solubility of the AuCl₃ in 0.013M solution of magnesium chloride is x, of Au³⁺ is x and of Cl⁻ is 3x. But we know that MgCl₂ is a strong electrolyte and it completely dissociates into its ions and will produce 2 moles of chloride ions. For this solution let we consider the volume is 1 liter then the concentration of chloride ions in MgCl₂ is 2(0.013)=0.026M.

So, in MgCl₂ solution concentration of Cl⁻ becomes = 3x + 0.026.

Value of Ksp for AuCl₃ = 3.2 × 10⁻²³

On putting all values on the Ksp equation, we get

Ksp = (x)(3x + 0.026)³

Value of 3x is negligible as compared to the 0.026, so the equation becomes

3.2 × 10⁻²³ = (x)(0.026)³

x = 3.2×10⁻²³ / (0.026)³

x = 1.81×10⁻²⁸M

Hence the molar solubility of AuCl₃ in 0.010M MgCl₂ is 1.81×10⁻²⁸M.

n a classroom, which comparison would a teacher most likely use for describing a mole? a cup of water and a liter of oil a dozen

s344n2d4d5 [400]

The teacher would use a dozen eggs and a dozen jellybeans to describe a mole.

A mole is simply a number of things.

Just as a dozen eggs is the same number as a dozen jellybeans, a mole of eggs is the same number as a mole of jellybeans.
