The formula  units  of Cr(ClO2)3  that  are in 6.85  moles of Cr(Clo203  is  <u>4.1237 x10^24  formula units</u>


 calculation

  the formula units are  calculated using of Avogadro's  law  constant

that is   according  to Avogadro's law   1  mole = 6.02 x10 ^23  formula units

                                                             6.85 moles= ?  formula units

by  cross  multiplication.

 = ( 6.85 moles   x 6.02  x10^23  formula units )  / 1 mole  = <u>4.1237  x 10 ^24  formula units</u>



<h3>The moles of  Oxygen  contained  in 6.85  moles of cr(ClO2)3  is    <em><u>41.1  moles</u></em></h3>

<em><u>  </u></em><u><em>calculation</em></u>

<em>moles   of  oxygen = number of oxygen atom in  Cr(ClO2)3  x   6.85(moles of  Cr(ClO2)3</em>

calculate the number of   oxygen atoms that  are in Cr(ClO2)3

that is  2 x 3 = 6 atoms of Oxygen.

moles is therefore =  6  x 6.85 moles= 41.1 moles

The pathway by which carbon is transferred from living organisms to the atmosphere is called:
Phoenix [80]

Answer:

cellular respiration

Explanation:

All exergonic processes produced in the cell, through which substances oxidize and chemical energy is released, are grouped under the name of cellular respiration, but to break down an organic molecule the cells employ, mainly dehydrogenations that can be carried carried out in the presence or absence of atmospheric O2 oxygen. There are therefore two types of breathing: aerobic respiration and anaerobic respiration. The latter also called fermentation.

Aerobic respiration  (oxidative phosphorylation)

- Use molecular O2.

- It degrades glucose to CO2 and H2O

- Exergonic

- Recovers about 50% of chemical energy

- Present in most organisms.

- It uses enzymes located in the mitochondria.

If you are using 3.00% (mass/mass) hydrogen peroxide solution and you determine that the mass of solution required to reach the
Maurinko [17]

Answer:

0.004522 moles of hydrogen peroxide molecules are present.

Explanation:

Mass by mass percentage of hydrogen peroxide solution = w/w% = 3%

Mass of the solution , m= 5.125 g

Mass of the hydrogen peroxide = x

w/w\% = \frac{x}{m}\times 100

3\%=\frac{x}{5.125 g}\times 100

x=\frac{3\times 5.125 g}{100}=0.15375 g

Mass of hydregn pervade in the solution = 0.15375 g

Moles of hydregn pervade in the solution :

=\fraC{ 0.15375 g}{34 g/mol}=0.004522 mol

0.004522 moles of hydrogen peroxide molecules are present.

The half-life of a strontium isotope is 25 years. How much of this particular isotope will remain after 100 years if the startin
Phoenix [80]

Answer:

1 gram

Explanation:

Half life = 25 years

Starting mass = 16 grams

Time = 100 years

Number of half lives = Time / Duration of Half life = 100 / 25 = 4

After first Half life;

Remaining mass = 16 / 2 =  8 g

After Second Half life;

Remaining mass = 8 / 2 =  4 g

After Third Half life;

Remaining mass = 4 / 2 =  2 g

After Fourth Half life;

Remaining mass = 2 / 2 = 1 g
