Why do you think dark surfaces absorb radiation better than light surfaces?
laiz [17]

Your answer→ <em>The lighter side absorbs less of the incident light, reflecting some of the energy. Darker materials also emit radiation more readily than light-colored materials, so they cool faster.</em>

At 600. K how many moles of gas are in a 1.00 L cylinder at atmospheric pressure?
Anton [14]

Answer:

0.02moles

Explanation:

To answer this question, the general gas law equation is used. The General gas law is:

Pv = nRT

Where; P = standard atmospheric pressure (1 atm)

V = volume (L)

n = number of moles

R = Gas law constant

T = Temperature

For this question; volume = 1.00L, atmospheric pressure (P) = 1 atm, R = 0.0821 L-atm / mol K, T = 600K, n = ?

Therefore; Pv = nRT

n = PV/RT

n = 1 × 1/ 0.0821 × 600

n = 1/49.26

n = 0.0203moles

Hence, there are 0.02 moles of gas.

Zinc(II) sulfide reacts with oxygen according to the reaction: A reaction mixture initially contains 3.0 mol ZnS and 2.0 mol O2.
tiny-mole [99]

Answer:

Excess reagent is the ZnS. After the reaction is complete, 1.67 moles of sulfide remain.

Explanation:

This is the reaction to work with:

2ZnS + 3O₂  →  2ZnO + 2SO₂

Limiting reagent is the oxygen. We confirm it by a rule of three

2 moles of sulfide can react to 3 moles of O₂

Therefore 3 moles of ZnS will react to (3 . 3) / 2 = 4.5 moles (we need 4.5 moles of O₂ and we only have 2 moles, that's why the O₂ is the limiting)

Excess reagent is the zinc (II) sulfide

3 moles of oxygen react to 2 moles of ZnS

2 moles of O₂ will react to (2 . 2) / 3 = 1.33 moles of ZnS (it is ok, be cause we have 3 moles, and we need only 1.33)

After the reaction is complete ( 3 - 1.33) = 1.67 moles of sulfide remain.
