Answer:

feel slippery

Explanation:

Bases are certain metallic oxides, metallic hydroxides and aqueous ammonia. They typically have the following characteristics;

The aqueous solution of many of them have a bitter taste.
The aqueous solutions of bases have soapy or slippery feel and the strong bases are very caustic to the skin.
Their aqueous solutions have a pH greater than 7.
Bases have the ability to change the color of indicators.
They are conduct electricity and are said to be electrolytes.

From the choices given, the fitting answer is that bases have a slippery feel.

Calculate ΔH⁰298 (in kJ) for the process P(s) + 5/2 Cl2(g) → PCl5(g) from the following information.

Viefleur [7K]

Answer:

$\Delta H_{298}^{0}$ for the process is -375 kJ

Explanation:

Given reaction is a combination of the two given elementary steps.

Summation of change in standard enthalpy ( $\Delta H_{298}^{0}$ )of the two elementary reactions give $\Delta H_{298}^{0}$ of the reaction $P(s)+\frac{5}{2}Cl_{2}(g)\rightarrow PCl_{5}(g)$ .

$P(s)+\frac{3}{2}Cl_{2}(g)\rightarrow PCl_{3}(g)$ ...... $\Delta H_{1}=-287kJ$

$PCl_{3}(g)+Cl_{2}(g)\rightarrow PCl_{5}(g)$ ...... $\Delta H_{2}=-88kJ$

-----------------------------------------------------------------------------------------------------

$P(s)+\frac{5}{2}Cl_{2}(g)\rightarrow PCl_{5}(g)$

$\Delta H_{298}^{0}$ = $\Delta H_{1}+\Delta H_{2}=-287kJ-88kJ=-375kJ$

What happened to the concentration of the product of H2O when the reaction shifts to the left

lilavasa [31]

I might need a diagram for this, but I have a vague idea of what you are talking about.

If H20 is going left it means the temperature is going lower.

The molecules will condense to slowly become ice
