Why does water with salt in it freeze much more slower than water without it ? Explain
serg [7]
When you add salt to water, you lower to freezing point of the substance.

So for example, normal water freezes at 0°C. But water with salt in it won't freeze at 0°C, because its freezing point is lowered. 

In answer to the question. It takes longer for water with salt in it to freeze because the substance requires a lower temperature than normal water to freeze.

Show the calculation of the mole fraction of each gas in a 1.00 liter container holding a mixture of 8.65 g of CO2 and 4.32 g of
Vlad1618 [11]

Answer:

0.745 and 0.245

Explanation:

Mole fraction (χ) is  the number of moles of a component divided by the total number of moles in a mixture.  

We must calculate the moles of each component.  

Let CO₂ be Gas 1 and SO₂ be Gas 2.

1. Calculate the moles of each gas.

\text{n} _{1} = \text{8.65 g} \times \dfrac{\text{1 mol}}{\text{44.01 g}} = \text{0.1965 mol}\\\\\text{n} _{2} = \text{4.32 g} \times \dfrac{\text{1 mol}}{\text{64.06 g}} = \text{0.067 44 mol}

2. Calculate the total moles.

n_{\text{tot}} = \text{n}_{1} + \text{n}_{2} = \text{0.1965 mol} +\text{0.067 44 mol} = \text{0.2640 mol}

3. Calculate the mole fraction of each component

\chi_{1} =\dfrac{0.1965}{0.2640} = \mathbf{0.745}\\\\\chi_{2} =\dfrac{0.06744}{0.2640} = \mathbf{0.255}

chemical potential energy, thermal energy, electrical energy, sound energy

Explanation:

the coal is chemical potential energy because it is just sitting there, the coal fueled power plant is thermal energy because it is using the heat from the coal to work the power plant, that is then turned into electrical energy, which then goes to the radio which displays sound energy

if the following is one strand of DNA what would be the corresponding strand of mRNA that is sequenced from it
Dmitrij [34]

Answer:

U A G C C A U C G G A U C C G A U

Explanation:

In DNA, A=T, C=G, and vice versa. RNA has U instead of T. So dna to rna: adenine = uracil, thymine = adenine, cytosine = guanine, and guanine = cytosine.

The reaction: 2 SO2(g) + O2(g) --&gt; 2 SO3(g) has an equilibrium constant of K1. What is the K value for the reaction: SO3(g) -
Murljashka [212]

<u>Answer:</u> The value of equilibrium constant for reverse reaction is (\frac{1}{K_1})^{1/2}

<u>Explanation:</u>

The given chemical equation follows:

2SO_2(g)+O_2(g)\rightarrow 2SO_3(g)

The equilibrium constant for the above equation is K_1

We need to calculate the equilibrium constant for the reverse equation of above chemical equation, which is:

SO_3(g)\rightarrow SO_2(g)+\frac{1}{2}O_2(g)

The equilibrium constant for the reverse reaction will be the reciprocal of the initial reaction.

If the equation is multiplied by a factor of '\frac{1}{2}', the equilibrium constant of the reverse reaction will be the 1/2 power of the equilibrium constant  of initial reaction.

The value of equilibrium constant for reverse reaction is:

K_{eq}'=(\frac{1}{K_1})^{1/2}

Hence, the value of equilibrium constant for reverse reaction is (\frac{1}{K_1})^{1/2}
