Answer:

Height and mass

Explanation:

The potential energy of a body is the energy due to the position of a body.

It is mathematically expressed as:

Potential energy = m g h

m is the mass of the body

g is the acceleration due to gravity

h is the height of the body

Acceleration due to gravity on the earth surface is a constant.

As mass and height of a body increases, the acceleration due to gravity will also increase.

Write the TOTAL IONIC EQUATION between zinc and hydrochloric acid.

Andreyy89

Answer : The net ionic equation will be,

$Zn(s)+2H^+(aq)\rightarrow Zn^{2+}(aq)+H_2(g)$

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The balanced ionic equation between zinc and hydrochloric acid will be,

$Zn(s)+2HCl(aq)\rightarrow ZnCl_2(aq)+H_2(g)$

The ionic equation in separated aqueous solution will be,

$Zn(s)+2H^+(aq)+2Cl^-(aq)\rightarrow Zn^{2+}(aq)+2Cl^-(aq)+H_2(g)$

In this equation, $Cl^-$ is the spectator ion.

By removing the spectator ion from the balanced ionic equation, we get the net ionic equation.

The net ionic equation will be,

$Zn(s)+2H^+(aq)\rightarrow Zn^{2+}(aq)+H_2(g)$

the temperature of a balloon rises from 275 degrees k to 395 degrees k, what would the ending volume be if it started at 5 L

Airida [17]

<h3>Answer:</h3>

7.182K

<h3>Explanation:</h3>

From the question we are given;

Initial temperature, T1 = 275 K
Final temperature, T2 = 395 K
Initial volume, V1 = 5 L

We are required to calculate the final volume, V2

Charles's law is the law that relates the volume of a gas and its temperature.
It states that the volume of a fixed mass of a gas and its absolute temperature are directly proportional at a constant pressure.
Therefore;

$\frac{V1}{T1}=\frac{V2}{T2}$

To calculate, V2 we rearrange the formula;

$V2=\frac{V1T2}{T1}$

$V2=\frac{(5L)(395K)}{275}$

$V2=7.182K$

Therefore, the ending volume will be 7.182K
