Answer:i don't rlly get the question but this is what i found on the internet :/

Explanation:

When the temperature is increased, the position of equilibrium moves in the endothermic direction to reduce the temperature. ... This means that as the temperature is increased, the position of equilibrium moves to the left, and the yield of ammonia decreases.

If 0.8675 g of KHP requires 24.56 mL of an NaOH solution to reach the equivalence

ValentinkaMS [17]

Answer:

$M_{base}=0.173M$

Explanation:

Hello there!

In this case, since the titration of acids like KHP with bases like NaOH are performed in a 1:1 mole ratio, it is possible for us to know that their moles are the same at the equivalence point, and the concentration, volume and moles are related as follows:

$n_{acid}=M_{base}V_{base}$

Thus, by solving for the volume of the base as NaOH, we obtain:

$M_{base}=\frac{n_{acid}}{V_{base}} \\\\M_{base}=\frac{0.8675g*\frac{1mol}{204.22g} }{0.02456L} \\\\M_{base}=0.173M$

Best regards!

A 75.0-milliliter lightbulb is filled with neon. There are 7.16 × 10-4 moles of gas in it, and the absolute pressure is 116.8 ki

Fantom [35]

Answer:- 1467 K

Solution:- It asks to calculate the kelvin temperature of the light bulb. Looking at the given info, it is based on ideal gas law equation, PV=nRT.

Given: $n=7.16*10^-^4moles$

V = 75.0 mL = 0.0750 L

P = 116.8 kPa

We know that, 101.325 kPa = 1 atm

So, $116.8kPa(\frac{1aym}{101.325kPa})$

= 1.15 atm

R is universal gas constant and it's value is $0.0821\frac{atm.L}{mol.K}$ .

T = ?

Let's plug in the values in the equation and solve it for T.

$1.15(0.0750)=7.16*10^-^4*0.0821(T)$

0.08625 = 0.00005878(T)

$T=\frac{0.08625}{0.00005878}$

T = 1467 K

So, the temperature of the light bulb would be 1467 K.

Snezhnost [94]

The answer is "chemical properties". The original water is split apart by the current
to form its constituent elements, hydrogen & oxygen. This is a chemical change, as 
the original water is lost and new substances, H2 & O2, are produced. 
Hope this answers your question.
