What is the total charge of a nucleus of a nitrogen atom?

Answers

Every atom has the same number of electrons as there are protons, thus making every atom neutrally charged. Therefore, there is no charge in a nitrogen atom, or any atom to begin with. The only possibly charged things are ions.

The charge of every atom is neutral. This is because the positively charged protons are cancelled out by the negatively charged electrons.

A substance has a mass of 360 g and a volume of 7.5 cm3. What is its density?a. 2700 g/cm3
c. 480 g/cm3
b. 270 g/cm3
d. 48 g/cm3

Answers

D = g / cm³

Density = mass / volume

D = 360 g / 7.5 cm³

D = 48 g/cm³

answer D

50 grams of acetic acid C2H4O2 are dissolved in 200 g of water. Calculate the weight % and mole fraction of the acetic acid in the solution

Answers

$50g$ $of$ $C_2H_4O_2$ $in$ $200g$ $H_2O$

so:

$(50)/(200+50)+100\%= (50*100)/(250)\%=20\%$

$MW of acid = 2*C+4*H+2*O = 2*12+4*1+2*16=$

$=24+4+32=60g/mol$

so:

$(50g)/(60g/mol)\approx0.83moles$

it means that

in $50g$ of acid there is $\approx0.83$ moles of acid

$MW of H_2O = 2*H+O=2*1+16=2+16=18g/mol$

so:

$(200g)/(18g/mol)\approx11.11moles$

it means that:

in $200g$ of water there is $\approx11.11$ moles of water

therefore:

$(0.83mol)/(11.11mol+0.83mol)= (0.83mol)/(11.94mol)=0.069$

So your answers are:

$20\%$

and the mole fraction is:

$0.069$

Reaction 2 occurs when an excess of 6 M HCI(aq) solution is added to 100. mL of NaOCl(aą) of unknown concentration. If the reaction goes to completion and 0.010 mol of Cl2(g) is produced, then what was the molarity of the NaOCl(aq) solution? (A) 0.0010 M
(B) 0.010 M
(C) 0.10 M
(D) 1.0 M

Answers

The molarity of the NaOCl solution is 0.10M

The correct answer to the question is Option C. 0.10 M

We'll begin by calculating the number of mole of NaOCl required to produce 0.010 mole of Cl₂.This can be obtained as follow:

NaOCl + 2HCl —> Cl₂ + NaCl + H₂O

From the balanced equation above,

1 mole of NaOCl reacted to produce 1 mole of Cl₂.

Therefore

0.010 mole of NaOCl will also react to produce 0.010 mole of Cl₂.

Finally,we shall determine the molarity of the NaOCl solution.

Mole of NaOCl = 0.01 mole

Volume = 100 mL = 100 / 1000 = 0.1 L

Molarity of NaOCl =?

Molarity = mole / Volume

Molarity of NaOCl = 0.01 / 0.1

Molarity of NaOCl = 0.1 M

Therefore, the molarity of the NaOCl solution is 0.1 M

Answer:

Option C 0.10 M

Explanation:

you are not providing the reaction, but luckily we have data to write the equation. We know that we are taking HCl and NaOCl to produce Cl2, the reaction is as follow:

NaOCl + 2HCl ---------> Cl₂ + NaCl + H₂O

From this reaction, we know that we have excess of acid that is added to 100 mL (0.1 L) of NaOCl, and this produces 0.010 moles of Chlorine.

All we have to do here, is apply stechiometry. We already know that the acid is in excess, so the moles produced would be the moles of the limiting reactant, in this case, the NaOCl.

According to the reaction NaOCl and Cl2 has a mole ratio of 1:1, so the moles of Cl2 would be the same moles that NaOCl lost so:

moles Cl2 = moles NaOCl = 0.010 moles

Then the concentration:

M = 0.010 / 0.1

M = 0.10 M

This is the molarity of NaOCl

Choose the pieces of evidence that supported the existence of Pangaea and continental drift theory.o Fossilized plants and animals of the same species found on separate continents.
o Geological features, such as mountain ranges, that align on matching coasts of different continents.
o Island arc ranges are still connected under the Atlantic Ocean.
o Antarctica's glacial features are similar to the Arctic's.

Answers

Pangaea is scientifically known as the original whole mass of land that eventually was divided into separate mass entities called continents as a result to natural phenomena like earthquakes. This is more explained inthe continental drift theory. After rigorous collection of evidences, scientists noticed that fossilized plants and animals of the same species, also with the coastlines match on different continents. The answers are the first and second choices (A and B).

Fossilized plants and animals of the same species found on separate continents.
