An antacid tablet was dissolved in water and 10mL of 0.16M HCl was added. After the acid had reacted with the tablet it required
Mnenie [13.5K]

Answer:

0.0008 mole of HCl

Explanation:

From the balanced equation between HCl and NaOH:

HCl + NaOH --> NaCl + H_2O

1 mole of acid requires 1 mole of base for neutralization.

mole = molarity x volume

mole of NaOH = 0.02 x 0.04 = 0.0008 mole

mole HCl = 0.16 x 0.01 = 0.0016 mole

Since 1 mole of NaOH requires 1 mole of HCl for neutralization, it means that 0.0008 mole of NaOH will require 0.0008 mole of HCl. The remaining mole of HCl must have been neutralized by the antiacid:

0.0016 - 0.0008 = 0.0008 mole.

Therefore, 0.0008 mole of HCl must have been neutralized by the antiacid.

please help timed !! due rn !! What happens to particle motion as two substances come to thermal equilibrium?
Gennadij [26K]

Answer:

When two substances that are of different temperatures are brought together and there is heat transfer such that the substances come to thermal equilibrium, the effect on the particle motion are as follows

1) The particle motion of the hotter body reduces, because its temperature reduces

2) The particle motion of the colder body increases, because its temperature increases

3) For gases, the volume and or pressure reduces for the hotter body, and if the temperature of the gas falls below the boiling point temperature, the gas will change into liquid

For the colder gas, only the volume and or pressure increases and the temperature rises

4) For liquids, if the temperature of the hotter liquid falls below the melting point, the hotter liquid will become a frozen solid

For the the colder liquid, if the temperature is raised above the boiling point, the liquid changes into gas and the temperature does not rise above the boiling point temperature, until all the cold liquid has evaporated

5) For solids, the vibration of the particles of the hotter substance reduces and the solid becomes more brittle

For the colder body, the rise in temperature causes an increase in vibration of the particles, and if the temperature rises above the melting point, the colder solid will begin to melt
