Answer: Order of the elements from most reactive to least reactive is:

Mg >  Zn > Fe > H > Cu

Explanation: Reactivity of the elements is the tendency of the elements to loose or gain electrons with ease.

As, all the given elements are metals, so the metals which will loose electrons easily will be more reactive. To study the reactivity of metals, we use reactivity series.

The metals which are more reactive are placed on the top of the reactivity series and which are less reactive are placed at the bottom.

Hence, the order of the elements from most reactive to least reactive is:

Mg >  Zn > Fe > H > Cu

Reactivity series is attached below.

Explain why the pressure in a sealed container of gas decreases when heat is added to the system?
weeeeeb [17]

Answer:

the question is bogus

see explanation

Explanation:

explain why the pressure in a sealed container of gas decreases when heat is added to the system?

when you add heat to the gas molecules in a sealed container, the molecules move faster and the pressure INCREASES!!!

IT DOES NOT DECREASE

PV =nrT

IF THE O THEVOLUME IS FIXED (REIN A SEALED CONTAINER) AND THE  NUMBER OF MOLES n is FIXED, THEN THE PRESSURE IS DIRECTLY PROPORTIONAL THE TEMPERATURE

THE GREATER T, THE GREATER P

Phosgene, a poisonous gas, when heated will decompose into carbon monoxide and chlorine in a reversible reaction: COCl2 (g) <
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

2. River, reservoir, Lake, groundwater, rain

3. H2O

4. POW is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from water.

5. Reduces amount of chlorine, soil residue, and organic and inorganic substances. Helps in improving the taste. Smell and visual appearance of water.

6. Boiling, filtration, distillation, and chlorination

7. Dust, dirt, harmful chemicals, biological contaminants, radiological contaminants

8. It is the contamination of water bodies, usually as a result of human activities, in such a manner that negatively affects it legitimate uses.

9. Colorless, turbidity, taste And odor.

10. Hardness of water is caused by compounds of calcium and magnesium, and by a variety of other metals.
