Although coal is a complex mixture of substances, its elemental composition can be approximated by the formula <img src="https:/
Svetllana [295]

Answer:

The correct answer is option b.

Explanation:

2C_{135}H_{96}O_9NS+313O_2\rightarrow 270CO_2+2NO_2+2SO_2+96H_2O

Mass of coal burned = 1.00\times 10^6 metric ton = 1.00\times 10^6\times 10^3 kg=10^9 kg[/tex]

1 metric ton = 10^3kg

Molar mass of coal :

135\times 12g/mol+96\times 1g/mol+9\times 16 g/mol+1\times 14 g/mol+1\times 32 g/mol=1906 g/mol=1.906 kg/mol

1 g = 0.001 kg

Moles of coal ,n :\frac{10^9 kg}{1.906 kg/mol}=5.247\times 10^8 mol

If 2 moles of coal on combustion gives 270 moles of carbon dioxide than n moles of coal will give;

5.247\times 10^8 mol\times \frac{270}{2}=7.083\times 10^{10} mol of carbon dioxide.

Molar mass of carbon dioxide gas = 44 g/mol = 0.044 kg/mol

Mass of 7.083\times 10^{10} mol of carbon dioxide:

7.083\times 10^{10} mol\times 0.044 kg/mol=3.11\times 10^{11} kg

A 6.0 M HCI solution is diluted to make 500 mL of a 2.5 M HCI solution. What volume of the 6.0 M HCI solution is required to mak
rodikova [14]

Answer:

V₁   = 208.3 mL

Explanation:

Given data:

Initial molarity of HCl  = 6.0 M

Final volume = 500 mL

Final molarity = 2.5 M

Volume of initial solution required = ?

Solution:

Formula:

M₁V₁   =  M₂V₂

Now we will put the values in formula.

6.0 M × V₁   = 2.5 M ×500 mL

6.0 M × V₁   = 1250 M.mL

V₁   = 1250 M.mL / 6.0 M

V₁   = 208.3 mL

TRUE or FALSE: Any measurement that has been cubed is volume.
zmey [24]

Answer:

True

Explanation:

Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed.
