Acellus<br> How many grams of strontium<br> (Sr, 87.62 g/mol) are in 2.92<br> moles of strontium?
saul85 [17]

Answer:

There are 255, 85 grams of Strontium in 2,92 moles.

Explanation:

We perform a simple rule of three to calculate the number of grams, knowing that one mole of Sr weights 87, 62 grams:

1 mol Sr---------87, 62 grams

2,92 mol Sr-----x=(2,92 mol Sr x-87, 62 grams)/1 mol Sr= 255,8504 grams

A buffer is a solution that is a mixture of either a weak acid and its conjugate base or a weak base and its conjugate acid. Whe
leva [86]

Answer:

a. The conjugate base of an acidic buffer will accept hydrogen protons when a strong acid is added to the solution.

b. An acidic buffer solution is a mixture of a weak acid and its conjugate base.

e. The weak acid of an acidic buffer will donate hydrogen protons when a strong base is added to the solution.

Explanation:

<em>Which of the statements correctly describe the properties of a buffer?</em>

a. The conjugate base of an acidic buffer will accept hydrogen protons when a strong acid is added to the solution. TRUE. The conjugate base neutralizes the excess of hydrogen protons.

b. An acidic buffer solution is a mixture of a weak acid and its conjugate base. TRUE.

c. An acidic buffer solution is a mixture of a weak base and its conjugate acid. FALSE. This is a basic buffer solution.

d. The weak acid of an acidic buffer will accept hydrogen protons when a strong base is added to the solution. FALSE. The weak acid will react with the hydroxyl ions from the added base.

e. The weak acid of an acidic buffer will donate hydrogen protons when a strong base is added to the solution. TRUE. These hydrogen protons will form water.

f. The conjugate base of an acidic buffer will donate hydrogen protons when a strong acid is added to the solution. FALSE. It will accept hydrogen protons.

Why does earth have uranium
Rainbow [258]
The isotope U-235 is important because under certain conditions it can readily be split, yielding a lot of energy. It is therefore said to be 'fissile' and we use the expression 'nuclear fission'. Meanwhile, like all radioactive isotopes, they decay.

Give the empirical formula for C↓8H↓8
mr_godi [17]

Answer:

Empirical formula of  C₈H₈ =  CH

Explanation:

Data Given:

Molecular Formula = C₈H₈

Empirical Formula = ?

Solution

Empirical Formula:

Empirical formula is the simplest ration of atoms in the molecule but not all numbers of atoms in a compound.

So,

tha ration of the molecular formula should be divided by whole number to get the simplest ratio of molecule

        C₈H₈ Consist of  Carbon (C), and Hydrogen (H)

Now

Look at the ratio of these two atoms in the compound

                         C : H

                         8 : 8

Divide the ratio by two to get simplest ratio

                          C : H

                       8/8 : 8/8

                         1   :  1

So for the empirical formula is the simplest ratio of carbon to hydrogen 1 : 1

So the empirical formula will be

                     Empirical formula of  C₈H₈ =  CH
