Answer:

Ba(OH)₂(aq) + 2HCl(aq) → BaCl₂(aq) + 2H₂O(l).

Explanation:

1 mol of Barium Hydroxide with 2 moles of hydrochloric acid to produce 1 mol of barium chloride and 2 moles of water according to the equation:

Ba(OH)₂(aq) + 2HCl(aq) → BaCl₂(aq) + 2H₂O(l).

Answer: The molecular formula will be $C_8N_4H_{10}O_2$

Explanation:

Mass of C= 49.47 g

Mass of N = 28.85 g

Mass of O = 16.48 g

Mass of H = 5.20 g

Step 1 : convert given masses into moles.

Moles of C = $\frac{\text{ given mass of C}}{\text{ molar mass of C}}= \frac{49.47g}{12g/mole}=4.12moles$

Moles of N = $\frac{\text{ given mass of N}}{\text{ molar mass of N}}= \frac{28.85g}{14g/mole}=2.06moles$

Moles of O = $\frac{\text{ given mass of O}}{\text{ molar mass of O}}= \frac{16.48g}{16g/mole}=1.03moles$

Moles of H = $\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{5.20g}{1g/mole}=5.20moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C = $\frac{4.12}{1.03}=4$

For N = $\frac{2.06}{1.03}=2$

For O = $\frac{1.03}{1.03}=1$

For H = $\frac{5.20}{1.03}=5$

The ratio of C : N: O: H = 4: 2: 1: 5

Hence the empirical formula is $C_4N_2OH_5$

The empirical weight of $C_4N_2OH_5$ = 4(12)+2(14)+1(16)+5(1)= 97 g.

The molecular weight = 194.19 g/mole

Now we have to calculate the molecular formula.

$n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{194.19}{97}=2$

The molecular formula will be = $2\times C_4N_2H_5O=C_8N_4H_{10}O_2$

What does the kinetic theory explain?

olya-2409 [2.1K]

I believe the correct answer from the choices listed above is the third option. The kinetic theory explains that heat is due to the motion of molecules. Temperature is the measurement used to measure heat and is directly proportional to the average kinetic energy of the molecules.

Which two scenarios illustrate the relationship between pressure and volume as described by Boyle’s law?

Airida [17]

The correct answer is option 2 and 3.

The two scenarios that illustrate the relationship between pressure and volume as described by Boyle’s law are as follows:

2. The volume of an underwater bubble increases as it rises and the pressure decreases.

3. The pressure increases in an inflated plastic bag when the bag is stepped on.

According to Boyle's law, pressure of a gas is inversely proportional to its volume at constant temperature. This means that pressure rises as the volume increases and vice versa.
