Explain how heat is related to thermal energy
Flauer [41]

Answer: Heat energy is another name for thermal energy.

Explanation:

As thermal energy comes from moving particles, it is a form of kinetic energy. Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature.

A sealed vessel initially contains 100 g of chlorine gas and 90 g of hydrogen gas. The two gases undergo reaction to form HCl. W
EleoNora [17]

Answer:

d.

Explanation:

H2 + Cl2 = 2HCL

From the equation 2g hydrogen combine with 71g of chlorine.

So 35.5 g Cl2 combines with 1g of H2

There are 100g of Cl2 so this will, by proportion, react with 100/35.5 g hydrogen.

This is 2.8 g hydrogen so the mass of HCl formed = 102.8 g.

Chemical equilibrium between gaseous reactants and products is shown.
Vinvika [58]

Answer:

The reaction is shifted to the left.

Explanation:

  • Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
  • When there is a decrease in pressure, the equilibrium will shift towards the side with more no. of moles of gas molecules of the reaction.
  • The reactants side (left) has 4.0 moles of gases and the products side (right) has 2.0 moles of gases.
  • So, decreasing the pressure will shift the reaction to the side with more moles of gas (left side).
  • <em>so, the reaction is shifted to the left.</em>

From the Henderson-Hasselbalch equation, explain how the ratio [Al/[HA] changes with changing pH
Kryger [21]

Answer:

The ratio [A-]/[HA] increase when the pH increase and the ratio decrease when the pH decrease.

Explanation:

Every weak acid or base is at equilibrium with its conjugate base or acid respectively when it is dissolved in water.

HA + H_{2}O ⇄ A^{-} + H_{3}O^{+}

This equilibrium depends on the molecule and it acidic constant (Ka). The Henderson-Hasselbalch equation,

pH = pKa + Log \frac{[A^{-}]}{[HA]}

shows the dependency between the pH of the solution, the pKa and the concentration of the species. If the pH decreases the concentration of protons will increase and the ratio between A- and AH will decrease. Instead, if the pH increases the concentration of protons will decreases and the ratio between A- and AH will increase.
