We can change a gas to a liquid by INCREASING the temperature and DECREASING the pressure

Answer: By decrease of temperature and increase of pressure

Explanation: Gas is the state of matter in which particles are very loosely bound and hence can easily move past one another very easily as the inter molecular forces are weakest.

Liquid is the state of matter in which particles are tightly bound as compared to gases as they have strong inter molecular forces as compared to gas.

Thus for converting gas to liquid, the molecules have to brought closer which can be done by decrease of temperature or increase of pressure.

Decrease in temperature decreases the kinetic energy and hence the random movement will be restricted. Increase in pressure will bring the molecules close. Thus converting gas to liquid.

What is the mass of KOH found in a 785 mL of a 1.43 M solution of KOH

My name is Ann [436]

Molarity is defined as the ratio of number of moles to the volume of solution in litres.

The mathematical expression is given as:

$Molarity = \frac{Number of moles}{volume of solution in litres}$

Here, molarity is equal to 1.43 M and volume is equal to 785 mL.

Convert mL into L

As, 1 mL = 0.001 L

Thus, volume = $785\times 0.001$ = 0.785 L

Rearrange the formula of molarity in terms of number of moles:

$Number of moles =molarity\times volume of solution in litres$

n = $1.43 M \times 0.785 L$

= 1.12255 mole

Now, Number of moles = $\frac{mass in g}{molar mass}$

Molar mass of potassium hydroxide = 56.10 g/mol

1.12255 mole = $\frac{mass in g}{56.10 g/mol}$

mass in g = $1.12255 mole\times 56.10 g/mol$

= 62.97 g

Hence, mass of $KOH$ = 62.97 g

A base has Kb of 2.5 x 10-11. which of the following statements is true?(1 point)

Furkat [3]

I disagree with the answer pick of D. If you have a neutral pH 7 solution and you proceed to add a base even with an relatively insignificantly low Kb your solution would still be more basic then acidic. The answer should be b which is true that the base only ionizes slightly in aqueous solution. This is also truer to the definition of what Kb represents.
