Nitrogen dioxide gas is dark brown in color and remains in equilibrium with dinitrogen tetroxide gas, which is colorless.

Chemistry
1 answer:
sukhopar [10]2 years ago
8 0

Answer:

This reaction is exothermic because the system shifted to the left on heating.

Explanation:

2NO₂ (g) ⇌ N₂O₄(g)

Reactant => NO₂ (dark brown in color)

Product => N₂O₄ (colorless)

From the question given above, we were told that when the reaction at equilibrium was moved from room temperature to a higher temperature, the mixture turned dark brown in color.

This simply means that the reaction does not like heat. Hence the reaction is exothermic reaction.

Also, we can see that when the temperature was increased, the reaction turned dark brown in color indicating that the increase in the temperature favors the backward reaction (i.e the equilibrium shift to the left) as NO₂ which is the reactant is dark brown in color. This again indicates that the reaction is exothermic because an increase in the temperature of an exothermic reaction will shift the equilibrium position to the left.

Therefore, we can conclude that:

The reaction is exothermic because the system shifted to the left on heating.

Which gas law states that the pressure of a gas decreases when volume is increased and the temperature is unchanged
Nesterboy [21]

Answer: Boyle's law

Explanation: It states that pressure of a gas is inversely proportional to the volume of a gas at constant temperature.

P∝\frac{1}{V}       at constant temperature

or If the pressure of gas is decreased, the volume increases if the temperature is unchanged and If the pressure of gas is increased, the volume decreases if the temperature is unchanged.

P_1V_1=P_2V_2

What do the three types of mixtures have in common? <br> (colloid, solution, suspension)
trasher [3.6K]

Answer:

A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. The particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas.

aluminum bromide reacts with chlorine gas to produce aluminum chloride and bromide gas. if we have 9 moles of chlorine gas. how
Luda [366]

Moles of Bromine produced = 9 moles

<h3>Further explanation</h3>

Given

9 moles of Chlorine gas

Word equation

Required

Moles of Chlorine produced

Solution

We change the word equation into a chemical equation (with a formula)

Aluminum bromide reacts with chlorine gas to produce Aluminum chloride and bromide gas

2AlBr₃+3Cl₂⇒2AlCl₃+3Br₂

moles Cl₂ = 9

Maybe you mean, <em>how many moles of Bromine can we produce?</em>

From equation, mol ratio Cl₂ : Br₂ = 3 : 3, so mol Br₂=mol Cl₂=9 moles

Which phrase describes non-foliated rocks? only one!
irinina [24]

Answer:

include quartzite and marble

Explanation:

non-foliated rocks are

1. metamorphic rocks

2. they are formed in the surrounding of igneous rocks

3. The environmental condition of formation of non-foliated rocks are that temperature is very high

4. pressure is very low but equal from all direction on igneous rocks

5. The constituent material crystalizes to form large rocks in which atoms are tightly and closely packed. Due to this density of these rocks are also higher.

Example of such rocks are

Quartzite : Its  constituent material are mineral quartz and metamorphosed sandstone

Marble : its constituent material are mineral calcite; metamorphosed limestone

Hence, include quartzite and marble is the correct choice.
