The energy changes in chemical reactions occurs when atoms _____ to form new substances.

Zanzabum

A chemical reaction is marked by new substance formation. The energy changes in chemical reactions occur when atoms rearrange to form new substances.

<h3>What is a chemical reaction?</h3>

A chemical reaction is said to be the process that is characterized by the formation of new substances by the alteration of the chemical composition and the properties of the compound or the molecule.

The reaction results in a new product by the rearrangement of the atoms of the reactant molecule by breaking and creating chemical bonds. The bonds are altered by the change in energy.

Therefore, rearrangement is the correct blank.

Chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl(aq) , as described b

Katyanochek1 [597]

Answer:

$m_{MnO_2}=1.378gMnO_2$

Explanation:

Hello,

In this case, we first apply the ideal gas equation to compute the moles of produced chlorine:

$n_{Cl_2}=\frac{PV}{RT}=\frac{765 Torr*\frac{1atm}{760Torr}*0.385L}{0.082\frac{atm*L}{mol*K}*298.15K} =0.01585molCl_2$

Then, by considering the given reaction, applying the stoichiometry, that shows a 1 to 1 relationship between chlorine and manganese dioxide, we find:

$m_{MnO_2}=0.01585molCl_2*\frac{1molMnO_2}{1molCl_2} *\frac{86.937gMnO_2}{1molMnO_2} \\m_{MnO_2}=1.378gMnO_2$

Best regards.

Determine the gram formula mass of the product

dimulka [17.4K]

For the whole set of problems, always remember the Avogadro’s number is 6.023*10^23 units per mole of a substance. Units could be atoms, molecules or formula units.

The first question asks for the number of molecules of NaNO3. The molar mass of NaNO3 is 85 grams per mole. So,

150g NaNO3(1mole NaNO3/85 grams NaNO3)(6.023*10^23 molecules/1mole NaNO3)=1.063*10^24 molecules of NaNO3

5.7*10^46 molecules of NaNO3(1mole NaNO3/6.023*10^23 molecules)(85 grams NaNO3/1mole NaNO3) = 8.044*10^24 grams NaNO3

For the molar mass of water, we have 18.02grams per mole.

301 moles H2O(18.02 grams H2O/1 mole H2O) = 5424.02 grams H2O

For the molar mass of sulfuric acid, we have 98.08 grams per mole.

25g H2SO4(I mole H2SO4/98.08g H2SO4) = 0.2549 mole H2SO4

For the molar mass of Ca(OH)2, we have 74.1 grams per mole.

252gCa(OH)2(1mol/74.1g)(6.023*10^23/1mol) = 2.048*10^24 molecules of Ca(OH)2

For the molar mass of calcium, we have 40 grams of Ca per mole.

6.7*10^35 atoms Ca(1 mole Ca/6.023*10^23 atoms)(40g Ca/1mol Ca) = 4.45*10^13 grams Ca
