Answer : Evaporative salts are majorly used as common salts or halites, which are highly and widely used to preserve foods, dye fabric, and de-ice roads.

Explanation : Evaporative salts are produced by evaporation of the sea water hence it is named as evaporative salts. These are mainly extracted through evaporation from seawater. The salts from shallow ponds where the seawater gets collected in a land, which is later harvested and then purified.

A solid can evaporate by melting into a liquid, which then evaporates; or by changing instantly into a vapor, or subliming. The rate of evaporation of a substance depends on its surface temperature, the pressure, and the humidity. Evaporation is the procedure by which a liquid or a solid changes into a vapor. A substance may evaporate by changing into a vapor at the surface, as when water evaporates from an uncovered dish.

tangare [24]

Explanation:

When a metal replaces another metal in solution, we say such a reaction has undergone a single displacement reaction.

In such a reaction, metal higher up in the activity series replaces another one due to their position.

To known the metal or metals that will replace the given copper, we need to reference the activity series of metals.

Every metal higher than copper in the series will displace copper from the solution.

So, there metals are: potassium, sodium, lithium, barium, strontium etc.

g n the Ideal Gas Law lab, how is the temperature of the hydrogen gas determined? Select one: The pressure of the gas is determi

Charra [1.4K]

Answer:

The volume of the gas is determined, which will allow you to calculate the temperature.

Explanation:

According to Charles law; the volume of a given mass of an ideal gas is directly proportional to its temperature at constant pressure.

This implies that, when the volume of an ideal gas is measured at constant pressure, the temperature of the ideal gas can be calculated from it according to Charles law.

Hence in the Ideal Gas Law lab, the temperature of an ideal gas is measured by determining the volume of the ideal gas.

snow_lady [41]

Answer:

Project 3.

Explanation:

Project 3's anticipated cost is 12 to 17 million dollars. It is a lower anticipated cost than Project 2 and Project 4, but higher than Project 1 by one million dollars at maximum cost anticipation. Additionally, the percentage of wildlife to benefit is 70-80%, which is second to the most wildlife to benefit which is Project 4 at 75-80%.

And finally, for community support for Project 3 - the chart lists it as high. This outclasses Project 2 and Project 4, but balances with Project 1. However, Project 1 costs 13 to 16 million dollars and only benefits 15-25% of wildlife.

Balancing Chemical Equation Na+Br2=NaBr

solniwko [45]

Answer:

2Na + Br2 = 2NaBr

Explanation:

In order to balance a chemical equation you make the make sure both sides have the same number of atoms on each side, you do this by multiplying on both sides as if it was a algebraic equation.

Na+ Br2 = NaBr

Na × 2 = Na2

Br × 2 = Br2

2Na + Br2 = 2NaBr

Hope this helps.
