AlladinOne [14]

Answer:

molality, mole fraction, solvent, solute, molarity.

Explanation:

<em>The expression of concentration that provides the moles of solute per kilograms of solvent is </em><em>molality</em><em>.</em>

b=\frac{n_{solute}}{m_{solvent}(kg)}

<em>If you place 5 moles of sodium chloride and 4 moles of sucrose into 11 moles of water, the </em><em>mole fraction</em><em> of sodium chloride would be 0.25 </em>

X(NaCl)=\frac{molesNaCl}{moles_{solution}} =\frac{5mol}{20mol} =0.25

<em>A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the </em><em>solvent</em><em> is water. </em>

The solvent is the component in major proportion and the one that defines the state of the solution.

<em>A solution is made up of 0.15 grams of sodium chloride in 1 liter of water. For this solution, the </em><em>solute</em><em> is sodium chloride. </em>

The solute is the component in minor proportion.

<em>A way to express concentration that provides the moles of solute per liter of solution is </em><em>molarity</em><em>.</em>

M=\frac{n_{solute}}{V_{solution}(L)}

Empirical formula of at least four binary ionic zn2+,pb4+,br-,s2-
Tasya [4]

Four binary ionic compounds that could be formed from each of these ions are;

  • Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
  • Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
  • Br^- - MgBr2, NaBr, CaBr2, KBr
  • S^2- - CaS, MgS, Na2S, K2S

<h3>What are binary ionic compounds?</h3>

Binary ionic compounds are those compounds that contain only two elements. The ionic compounds are those compounds that contain ions. The compounds are able to dissolve in water and they have high melting and boiling points.

Now, four binary ionic compounds that could be formed from each of these ions are;

  • Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
  • Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
  • Br^- - MgBr2, NaBr, CaBr2, KBr
  • S^2- - CaS, MgS, Na2S, K2S

A) What mass in grams of H20 is needed to react completely with 40.0 g of
Step2247 [10]

Answer:

m_{H_2O}=9.24gH_2O

Explanation:

Hello there!

In this case, since there is a 2:2 mole ratio between sodium peroxide and water according to the given reaction, it is possible to apply the following stoichiometric setup for the calculation of the required mass of water:

m_{H_2O}=40.0gNa_O_2*\frac{1molNa_O_2}{78gNa_O_2}*\frac{2molH_2O}{2molNa_O_2}  *\frac{18.02gH_2O}{1molH_2O} \\\\m_{H_2O}=9.24gH_2O

Rhia is using the above equation to investigate the carbon footprint, ccc, in kilograms of carbon dioxide (co_2)(co 2 ​ )left pa
Drupady [299]

Answer: -

0.2 Kg

Explanation: -

The equation used by Rhia for the carbon footprint measurement is

C = 0.2 B + 0.1 S

where S miles are by subway, B miles by bus and C is Kg of carbon dioxide.

From the equation we see the coefficient of B is 0.2.

Thus 0.2 Kg of carbon dioxide per mile the bus portion contributes to Rhia's carbon footprint.
