Determine the temperature change when a 100. g block of gold is supplied with 1.00 x 103 J of heat will give brainliest pls help
rusak2 [61]

Answer:

77.5°C

Explanation:

Data obtained from the question include the following:

Mass (M) = 100g

Heat (Q) = 1x10^3 J

Change of temperature (ΔT) =..?

Note: The specific heat capacity (C) of gold = 0.129 J/g°C

With the above information obtained from the question, we can obtain the change in temperature as follow:

Q = MCΔT

Divide both side by MC

ΔT = Q/MC

ΔT = 1x10^3 / (100 x 0.129)

ΔT = 77.5°C

Therefore, the change in temperature is 77.5°C

Phosgene, a poisonous gas, when heated will decompose into carbon monoxide and chlorine in a reversible reaction: COCl2 (g) &lt;
Advocard [28]

Answer:

8.08 × 10⁻⁴

Explanation:

Let's consider the following reaction.

COCl₂(g) ⇄ CO (g) + Cl₂(g)

The initial concentration of phosgene is:

M = 2.00 mol / 1.00 L = 2.00 M

We can find the final concentrations using an ICE chart.

     COCl₂(g) ⇄ CO (g) + Cl₂(g)

I       2.00            0            0

C        -x             +x           +x

E    2.00 -x          x             x

The equilibrium concentration of Cl₂, x, is 0.0398 mol / 1.00 L = 0.0398 M.

The concentrations at equilibrium are:

[COCl₂] = 2.00 -x = 1.96 M

[CO] = [Cl₂] = 0.0398 M

The equilibrium constant (Keq) is:

Keq = [CO].[Cl₂]/[COCl₂]

Keq = (0.0398)²/1.96

Keq = 8.08 × 10⁻⁴

When the equation Al2(SO4)3 + NaOH + Al(OH)3 + Na2SO4 is correctly balanced, what is the coefficient of Al(OH)3?
nevsk [136]
The balanced chemical formula should be Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4

Therefore the coefficient of Al(OH)3 is 2!

Hope that helps :)
