Answer:

Change the temperature and pressure

Explanation:

In case we are analyzing the solubility of a salt in some solvent, raising the temperature would increase the solubility of a salt generally. In contrast, at lower temperatures the solubility of ionic salts would decrease.

Now, another variation of this scenario might be solubility of gases. According to Henry's Law, $S = k_Hp$ , meaning that the solubility of a gas is directly proportional to its partial pressure. Therefore, the greater the pressure, the greater the solubility of a gas.

How much heat must be transferred to 100.0g of water to change its temperature by 35° C?

nekit [7.7K]

Answer:

14700J

Explanation:

From the question given, the following were obtained:

M = 100g

ΔT = 35° C

C = 4.2J/g °C

Q=?

The heat transferred can calculated for by using the following equation

Q = MCΔT

Q = 100 x 4.2 x 35

Q= 14700J

A reaction between liquid reactants takes place at −10.0°C in a sealed, evacuated vessel with a measured volume of 45.0L. Measur

maks197457 [2]

Answer: 0.0624 atm

Explanation:-

According to the ideal gas equation:

$PV=nRT$

P = Pressure of the gas = ?

V= Volume of the gas = 45.0 L

T= Temperature of the gas = -10.0°C = 263 K $0^00C=273K$

R= Gas constant = 0.0821 atmL/K mol

n= moles of gas

Moles of gas= $\frac{\text{ given mass}}{\text{ molar mass}}= \frac{19.0g}{146g/mole}=0.130moles$

$P=\frac{nRT}{V}=\frac{0.130\times 0.0821\times 263}{45.0}=0.0624atm$

The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm

What is the cause of change over time in a population?

Y_Kistochka [10]

The environment modifies.

Explanation:

A modification of the environment can lead to population changes overtime. The environment is very important for population dynamics.

It is predominantly made up of the factors that affects organisms and where they live.

If the resources in an environment gets depleted, organisms will be force to migrate from that place to another in search of more nutrient areas.

This and many other factor like climate, stability, etc causes changes to the population through time.
