Chemistry
1 answer:
dezoksy [38]3 years ago
3 0

Answer :

The substance is in the gas phase only in region  → 5

The substance is in both the liquid and the solid  phase in region  → 2

The substance is in only the liquid phase in region  → 3

The melting point is the temperature at region  → 2

The boiling point is the temperature at region → 4

Explanation :

Six phases of substance:

  • Melting or fusion : In this process the phase changes from solid state to liquid state at constant temperature.
  • Freezing : In this process the phase changes from liquid state to solid state at constant temperature.
  • Evaporation : In this process the phase changes from liquid state to gaseous state at constant temperature.
  • Condensation : In this process the phase changes from gaseous state to liquid state at constant temperature.
  • Sublimation : In this process the phase changes from solid state to gaseous state without passing through the liquid state at constant temperature.
  • Deposition : In this process the phase changes from gaseous state to solid state without passing through the liquid state at constant temperature.

Is milk a solution, suspension, compound , colloid ?
kakasveta [241]

Answer:

Colloids (heterogeneous)

The difference between a colloid and a suspension is that the particles will not settle to the bottom over a period of time, they will stay suspended or float. An example of a colloid is milk. Milk is a mixture of liquid butterfat globules dispersed and suspended in water.

What is the atomic weight of Na?
Zigmanuir [339]

Answer:

22.989769 u

Explanation:

The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668. Carbon-13: 0.0111 x 13.0034 = 0.1443.

What is the limiting reactant in a reaction where 10.0 mol of iron is treated with 12.0 mol of bromine? The product that forms i
hammer [34]

<u>Answer:</u> The limiting reagent in the reaction is bromine.

<u>Explanation:</u>

Limiting reagent is defined as the reagent which is completely consumed in the reaction and limits the formation of the product.

Excess reagent is defined as the reagent which is left behind after the completion of the reaction.

Given values:

Moles of iron = 10.0 moles

Moles of bromine = 12.0 moles

The chemical equation for the reaction of iron and bromine follows:

2Fe+3Br_2\rightarrow 2FeBr_3

By the stoichiometry of the reaction:

If 3 moles of bromine reacts with 2 moles of iron

So, 12.0 moles of bromine will react with = \frac{2}{3}\times 12.0=8moles of iron

As the given amount of iron is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.

Hence, bromine is considered a limiting reagent because it limits the formation of the product.

Thus, the limiting reagent in the reaction is bromine.
