26.25g

Explanation:

Given parameters:

Percentage of NaCl in ocean water = 3.5%

Mass of given seawater = 750g

Unknown:

Mass of NaCl in the seawater = ?

Solution:

This is a simple percentage problem:

We have been given that ocean water contains 3.5% of NaCl;

Therefore;

Mass of NaCl in seawater = Percentage of NaCl in ocean water x Mass of seawater

Mass of NaCl in seawater = $\frac{3.5}{100}$ x 750g = 26.25g

A sample of a gas in a balloon has a volume of 2.22 L and temperature of 23.9 °C. Calculate the volume when the temperature is r

nignag [31]

Answer:

Volume = 4.28L

Explanation:

Charles's gas law relates the volume and temperature of a gas at constant pressure. This law says that at constant pressures if we raise the temperature of a gas it will expand and if we reduce the temperature the volume will decrease. The formula is as follows:

${\frac {V_{1}}{T_{1}}}={\frac {V_{2}}{T_{2}}}$

So, the initial conditions are 2.22L and 23.9 °C ant the final conditions are 46.1 °C we replace them in the equation. And then we solve it.

${\frac {2.22}{23.9}}={\frac {V_{2}}{46.1}$

${\frac {2.22}{23.9}} {46.1}={V_{2$

${4.28}={V_{2$

The relationships among which variable quantities are expressed by the ideal gas law equation?

Eva8 [605]

The variable quantities are expressed by the ideal gas law equation are; 

pressure, volume, temperature, number of moles

This question is simply based on defining the ideal gas law.

Now, A gas is considered to ideal if its particles are so far from each other in such a manner that they don't exhibit any forces of attraction between themselves. Now, in real life this is not possible but under high temperatures and pressure, we can have something close to it and that's why ideal gas laws are very important.

This law states that states that the pressure, temperature, number of moles and volume of a gas are related to each other by the formula;

PV = nRT

Where;

P is pressure

V is volume

n is number of moles

T is temperature

R is ideal gas constant (This is fixed and not variable)

The variable quantities are expressed by the ideal gas law equation are;

pressure, volume, temperature, number of moles

Which relationship or statement best describes Delta Sfor the following reaction?

Wewaii [24]

Answer: $\Delta S$ < 0

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

For the reaction $CaO(s)+CO_2(g)\rightarrow CaCO_3(s)$

In this reaction gaseous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus $\Delta S$ is negative or less than zero.
