How many grams of Ba(OH)2 will dissolve in 100g of water at 75 degree Celsius

cricket20 [7]

Solubility is a function of temperature. But for this case solubility is not given at that certain temperature and it is somewhat difficult to find for certain datas. I would be using the solubility at 20 degrees celsius which is 1.85g/100g Water

.0185 g / g water = g barium hydroxide / 100 g

1.85 g of barium hydroxide can be dissolved in 100 g of water.

Hope this could help. Have a nice day.

Be sure to answer all parts.The equilibrium constant (Kc) for the formation of nitrosyl chloride, an orange-yellow compound, fro

miss Akunina [59]

Explanation:

Since, the given reaction is as follows.

$2NO(g) + Cl_{2} \rightleftharpoons 2NOCl$

Expression for $Q_{c}$ of this reaction is as follows.

$Q_{c} = \frac{[NOCl]^{2}}{[NO]^{2}[Cl_{2}]}$

Putting the given values into the above formula as follows.

$Q_{c} = \frac{[NOCl]^{2}}{[NO]^{2}[Cl_{2}]}$

= $\frac{(9.50)^{2}}{(4.40 \times 10^{-2})^{2} \times (1.80 \times 10^{-3})}$

= $\frac{90.25}{34.848 \times 10^{-7}}$

= $2.59 \times 10^{-7}$

Thus, we can conclude that $Q_{c}$ for the experiment is $2.59 \times 10^{-7}$ .

What creates an electric current in a battery?

kramer

Answer:

There's a separate chemical reaction happening at the positive electrode, where incoming electrons recombine with ions taken out of the electrolyte, so completing the circuit. The electrons and ions flow because of the chemical reactions happening inside the battery—usually two of them going on simultaneously.

What questions, if we were to answer them, would

Margarita [4]

Answer:

When our bodies are dry and wind blows by, we lose some energy to the air molecules. When are bodies are wet, we have a substance on our skin that likes to absorb heat. So when wind blows by, we lose a LOT of energy to the air molecules. When the body loses heat energy, our body temperature drops.
