Answer:

How Hot Or cold it is is how it may be perceived

Explanation:

Answer:

A.) You have been given grams of NaCl (11.0 g) and the volume of the solution (100 mL).

B.) You need to determine the moles of NaCl and the volume of the solution in liters. To find the moles of NaCl , you need to know the molar mass of NaCl.

C.) 1.88 M

Explanation:

To find the molarity of the solution, you need to (1) convert mL to L (by dividing by 1,000), then (2) convert moles NaCl to grams (via molar mass from periodic table), then (3) plug the values into the molarity equation.

Volume = 100 mL / 1,000 = 0.100 L

Molar Mass (NaCl) = 22.99 g/mol + 35.45 g/mol

Molar Mass (NaCl) = 58.44 g/mol

11.0 g NaCl          1 mole
-----------------  x  ---------------  = 0.188 moles NaCl

                           58.44 g

Molarity = moles / volume

Molarity = 0.188 moles / 0.100 L

Molarity = 1.88 M

The molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol, Option D is the correct answer.

The energy released when a fuel is oxidized by an oxidizing agent is called enthalpy of Combustion.

It is given that

a 1.0 g sample of magnesium is burned to form MgO. in doing so, 25.5 kj of energy are released.

Molecular weight of Magnesium = 24.35g

24.35 g makes 1 mole of Mg

1g = 1/24.35

For 0.04 moles  25.5 kJ is released

for 1 mole 25.5 *1/.04

= 620 kj/mol

Therefore the molar enthalpy of combustion in kj/mol of magnesium is 620 kj/mol.

Answer:

Water molecules' adhesion aids plants in moisture absorption at their roots. Water's initial boiling point is attributed to cohesion, which helps animals regulate their body temperature.

Explanation:

82.09% is the percent yield if 399 g is produced. Hence, option  C is correct.

Percent yield is the percent ratio of actual yield to the theoretical yield.

Given data:

Actual yield = 399 g

Theoretical yield = 486 g

%Yield = [tex]\frac{Actual \;Yield \;X \;100 }{Theoretical \;Yield}[/tex]

%Yield = [tex]\frac{399 gX \;100 }{486 g \;Yield}[/tex]

= 82.09%

82.09% is the percent yield if 399 g is produced.

Hence, option  C is correct.

Answer:

The periodic table

Explanation:

As you can see in the screenshot. Each element on the periodic table has an atomic number and a mass number. The atomic numbers are arranged in numerical order from right to left in the periodic table. The second number there is the atomic mass.

When doing stoichiometric ratios, you need to use the atomic mass of each element to determine the molecular/molar mass.

example. Find the molar mass of

H₂SO₄

Hydrogen (2) + sulphur (1) +oxygen (4)

= atomic mass of H(2)+ atomic mass S(1)+ atomic mass oxygen(4)

=1(2) + 32(1)+16(4)

=2+32+64

=98

N.B We do not use the co-efficient when looking for molar mass, we only use the atom and subscript

The balanced redox reaction, if it occurs in acidic solution, is

5C₂O₄²⁻(aq) + 2MnO₄⁻(aq) + 16H⁺-----> 10CO₂(g) + 2Mn²⁺(aq) + 8H₂O(l)

Redox reactions are those in which loss and again of electrons occur.

To balance the redox reaction, we must first break the whole reaction into half equations;

Oxidation half equation

[tex]\rm 5C_2O4^2^-(aq) + 10e + 8H^+----- > 10CO_2(g) + 4H_2O(l)[/tex]

Reduction half equation

[tex]\rm 2MnO_4^- (aq) + 10e + 8H^+----- > 2Mn^2+(aq) + 4H_2O(l)[/tex]

Now combine both the reactions

[tex]\rm 5C_2O_4^2-(aq) + 2MnO4^- (aq) + 16H^+----- > 10CO_2(g) + 2Mn^2+(aq) + 8H_2O(l)[/tex]
