Answer: The correct answer is $Ca(OH)_2$

Explanation:

A base is defined as the substance which looses hydroxide ions $(OH^-)$ when dissolved in water.

An acid is defined as the substance which looses hydrogen ions $(H^+)$ when dissolved in water.

From the given options:

AgO and NaCl are the salts. Both are ionic salts which are formed from the reaction of a metal and an non-metal.

HF is an acid because it released $H^+$ ions when dissolved in water. The equation for the ionization of HF follows:

$HF\rightleftharpoons H^++F^-$

$Ca(OH)_2$ is a base because it released $OH^-$ ions when dissolved in water. The equation for the ionization of $Ca(OH)_2$ follows:

$Ca(OH)_2\rightleftharpoons Ca^{2+}+OH^-$

Hence, the correct answer is $Ca(OH)_2$

frozen [14]

Cations mix with anions, so you know NH4+ won't mix with K+ and SO4(2-) won't miix with F-. For the reason that NH4+ and F- together have single charges, they'll mix in a 1:1 ratio, NH4F. There's two charges on SO4(2-), so it'll need two K+ to mix with, K2SO4.

Answer:

$V_1=23.3~mL$

Explanation:

In this case, we have a dilution problem. We have to remember that in the dilution procedure we go from a solution with higher concentration to a solution with lesser concentration. Therefore we have to start with the dilution equation:

$C_1*V_1=C_2*V_2$

Now we can identify the variables:

$C_1=~1.475_M$

$V_1=~?$

$C_2=~0.1374_M$

$V_2=~250.0~mL$

If we plug all the values into the equation:

$1.475_M*V_1=0.1374_M*250.0~mL$

And we solve for $V_1$ :

$V_1=\frac{0.1374_M*250.0~mL}{1.475_M}$

$V_1=23.3~mL$

I hope it helps!

The term that best describes a 10-gram of KCIO3 per 100 grams of water solution at 30 degrees celsius is:

In-s [12.5K]

The term that best described a 10 gram of KClO3 per 100 grams of water solution at 30 degree Celcius is Saturated. The solubility chart is needed for this work. If the solubility chart is drawn for KClO3, it will be observed that the proportion of KClO3 that is needed to dissolve in 100ml of water to make the solution saturated is 10 grams at 30 degree Celcius.
