Answer:

I think that gravity can be considered a force.

Explanation:

As the object falls, it moves faster and faster. Gravity is considered a universal force because it acts between any two masses anywhere in the universe. For example, there is a gravitational pull between the Sun and the Moon. Even small masses attract one another.

Hope this helped! :)

Answer: This is an oxidation-reduction (redox) reaction:

3 C-II - 12 e- → 3 CII (oxidation)

4 CrVI + 12 e- → 4 CrIII (reduction)

C2H5OH is a reducing agent, K2Cr2O7 is an oxidizing agent.

In part 2 of the experiment, you will be analyzing a sample of household bleach. A 0.0854 g sample of household bleach is comple

marysya [2.9K]

Answer:

The correct answer is option d.

Explanation:

$NaClO(aq)+2KI(s)+H_2O(l)\rightarrow NaCl(aq)+I_2(aq)+2KOH(aq)$ ..[1]

$I_2(aq)+2Na_2S_2O_3(aq)\rightarrow 2NaI(aq)+Na_2S_4O_6(aq)$ ..[2]

moles of sodium thiosulfate solution = n

Molarity of the sodium thiosulfate solution = 0.150 M

Volume of sodium thiosulfate solution used = 0.890 mL = 0.00089 L

$n=Molarity\times Volume (L)$

$n=0.150 M\times 0.00089 L=0.0001335 mol$

According to reaction [2], 2 moles of sodium thiosulfate reacts with 1 mol $I_2$ .

Then , 0.0001335 mol of sodium thiosulfate will reacts with:

$\frac{1}{2}\times 0.0001335 mol=0.00006675 mol$ of $I_2$

Moles of $I_2$ = 0.00006675 mol

According to reaction [1], 1 mol of $I_2$ is obatnied from 1 mol of NaClO.

Then 0.00006675 mol of $I_2$ will be obtained from:

$\frac{1}{1}\times 0.00006675 mol=0.00006675 mol$

Mass of 0.00006675 mol of NaClO=

0.00006675 mol × 74.44 g/mol = 0.00496887 g

Mass of sample = 0.0854 g

Percentage of NaClO in sample:

$\frac{0.00496887 g}{0.0854 g}\times 100=5.82\%$
