The atoms of element differ from each other based on the number of protons or electrons they have. The number of protons or electrons is called the atomic number of an element which serves as its original identity.

<span>Now, an isotope of an element differs in their number of neutrons but the number of protons or electrons are similar.</span>

A pupil adds 5 cm of 12 mol.dm sulphuric acids to make a 250 cmº solution. Calculate the
klemol [59]

Answer:

0.500 mol/dm³

Explanation:

Using the formula below;

CaVa = CbVb

Where;

Ca = concentration of acid (mol/dm³)

Cb = concentration of base (mol/dm³)

Va = volume of acid (cm³)

Vb = volume of base (cm³)

In accordance to the information provided in this question is;

Va = 5cm³

Vb = 250 cm³

Ca = 12 mol/dm³

Cb = ?

Using CaVa = CbVb

12 × 5 = Cb × 250

60 = 120Cb

Cb = 60/120

Cb = 0.500 mol/dm³

How many grams are in 2.5 moles of N2? <br><br> (2 decimal places)
Leokris [45]

Answer: How many grams are in 2.5 moles of N2?

Explanation: 1 mole is equal to 1 moles N2, or 28.0134 grams.

 One mole of N2 molecules would have a mass of 2 X 14.01 g = 28.02 g.

how many H+ ions are in a solution with a pH of 2 and how many H+ ions are in a solution with a pH of 6?
LiRa [457]

Answer:

i) pH = 2

pH = -log(H+)

:- (H+) = 10^(-2)

:- (H+) = 0.01 M

ii) pH = 6

pH = -log(H+)

:- (H+) = 10^(-6)

:- (H+) = 0.000001 M

Explanation:

By definition: pH = -log(H+).

Given your pH, solve for the H+ using the the following log rule:

if a = (+/-) log (b) then

b = 10^((+/-) a).

Also remember unit of concentration is molar (M)

How many grams of ammonia produced from 1000 grams of N2?
sleet_krkn [62]

Answer:

N2 + 3H2 ———> 2NH3

As we know 1000 grams ammonia is 58.82 moles so according to unitary method,

2 mole NH3 formed by 1 mole N2 hence 58.82 NH3 will be given by 29.41 moles N2.

No. Of moles = given mass/molar mass

Implies that

Mass of nitrogen required = 29.41*28 = 823.48 grams.
