Answer:

Cells produced by meiosis are genetically identical, and cells produced by mitosis are genetically unique.

Explanation:

Cells produced by mitosis possess half the genetic material of cells produced by meiosis. Mitosis only occurs in the presence of oxygen, while meiosis can occur in the absence of oxygen.

point)A chemist has 4.43 g of lithium carbonate and must make a 0.0600 mol/L solution.What volume of solution can be made?a) 0.0

ANTONII [103]

Explanation:

A chemist has 4.43 g of lithium carbonate and must prepare a 0.0600 mol/L (or 0.0600 M) solution. We have to find the volume of solution that can be made.

The molarity of a solution is defined like:

molarity = moles of solute/volume of solution in L

We already know the concentration of the solution (it is 0.0600 mol/L) and the volume is our unknown.

volume of solution in L = ?

molarity = 0.0600 mol/L

We still have to convert the mass of lithium carbonate into moles. To do that we will use the molar mass of the compound.

lithium carbonate = Li₂CO₃

mass of Li₂CO₃ = 4.43 g

molar mass of Li₂CO₃ = 73.89 g/mol

moles of Li₂CO₃ = 4.43 g * 1 mol/(73.89 g)

moles of Li₂CO₃ = 0.0600 moles

Finally we can replace the values in the formula and solve it for the volume of solution.

molarity = moles of solute/volume of solution in L

volume of solution in L = moles of solute/molarity

volume of solution in L = 0.0600 mol/(0.0600 mol/L)

volume of solution in L = 1.00 L

Answer: b) 1.00 L

What type of van der Waals interactions occur between molecules

BigorU [14]

Given what we know, we can confirm that the type of van der Waals interactions that occur between molecules of O2, SCl2, and CH4 in liquids of these substances are the presence of <u>London dispersion forces</u>.

<h3>What are London dispersion forces?</h3>

They are a force of attraction between atoms.
They are generated by electrostatic attraction.
These forces are common between atoms in close proximity and occur often when compounds have a symmetrical distribution of atoms.
They are generated by the formation of temporary dipoles.

Therefore, given the symmetry of the atoms disposition in these compounds and the temporary dipoles generated by the atoms being in close proximity, we can confirm that the van der Waals forces present in each compound are London dispersion forces.

When fluoride reacts with the metal it forms an F negative ion the fluorine Adam has gained an electron an undergone _______.

Anika [276]

Answer:

Reduction.

Explanation:

Fluorine atom has gained an electron and undergone reduction because when an atom gains electron it reduced itself thus acting as an oxidant to oxidize another atom .

For exam sodium fluoride NaF is a salt when sodium fluoride undergo breakdown at that time the fluoride atom gains an electron and is converted to F- anion by the process called reduction .
