The correct answer is correcting errors.

The prime activity of DNA polymerase is to synthesize DNA from nucleotides, that is, the building blocks of DNA. There are many kinds of DNA polymerase, which does an essential role in the replication of DNA and they generally function in pairs to duplicate one molecule of double-stranded DNA into two novel double-stranded molecules of DNA.

Apart from developing new copies of DNA, the DNA polymerase is accountable for proofreading the strand so that the misplaced or the wrong base pairs can be corrected. This maintains the veracity of the original strand of DNA, which is passed onto the daughter cells.

The following chemical reaction takes place in aqueous solution: AgF (aq)+ NH4Cl (aq) →AgCl(s)+ NH4F(aq) Write the net ionic equ

Nadusha1986 [10]

Answer:

The net ionic equation is: Ag⁺ (aq) + Cl ⁻ (aq) → AgCl (s)

Explanation:

1) Start by writing the total ionic equation:

The total ionic equation shows each aqueous substance in its ionized form, while the solid or liquid substances are shown with their chemical formula.

These are the ionic species:

AgF (aq) → Ag⁺ (aq) + F⁻ (aq)

NH₄Cl (aq) → NH₄⁺ (aq) + Cl ⁻ (aq)

NH₄F(aq) → NH₄⁺ (aq) + F⁻ (aq)

Then, replace each chemical formula in the chemical equation by those ionic forms:

Ag⁺ (aq) + F⁻ (aq) + NH₄⁺ (aq) + Cl ⁻ (aq) → AgCl (s) + NH₄⁺ (aq) + F⁻ (aq)

That is the total ionic equation.

2) Spectator ions:

The ions that appear in both the reactant side and the product side are considered spectator ions (they do not change), and so they are canceled.

In our total ionic equation they are F⁻ (aq) and NH₄⁺ (aq).

After canceling them, you get the net ionic equation:

3) Net ionic equation:

Ag⁺ (aq) + Cl ⁻ (aq) → AgCl (s) ← answer

What is the density of CHCL3 vapor at 1.00atm and 298K?

Advocard [28]

Answer:

4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.

Explanation:

By ideal gas equation:

$PV=nRT$

Number of moles (n)

can be written as: $n=\frac{m}{M}$

where, m = given mass

M = molar mass

$PV=\frac{m}{M}RT\\\\PM=\frac{m}{V}RT$

where,

$\frac{m}{V}=d$ which is known as density of the gas

The relation becomes:

$PM=dRT$ .....(1)

We are given:

M = molar mass of chloroform= 119.5 g/mol

R = Gas constant = $0.0821\text{ L atm }mol^{-1}K^{-1}$

T = temperature of the gas = $298K$

P = pressure of the gas = 1.00 atm

Putting values in equation 1, we get:

$1.00atm\times 119.5g/mol=d\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times 298K\\\\d=4.88g/L$

4.8 g/mL is the density of chloroform vapor at 1.00 atm and 298 K.

Which substance increases in solubility as the temperature decreases?

Arlecino [84]

NH₃ would. This is because of the fact that ammonia is a molecular gas while the other options are ionic crystals. Crystals increase in solubility when the temperature increases while gases increase in solubility while temperatures deceases.

I hope this helps. Let me know in the comments if anything is unclear or if you want me to explain anything is more detail.
