Answer:

$S_{(g)}+O_2_{(g)}\rightarrow SO_2_{(g)}$

Explanation:

Sulfur in the pressure of oxygen produces sulfur dioxide gas. The balanced chemical reaction is shown below as:-

$S_{(g)}+O_2_{(g)}\rightarrow SO_2_{(g)}$

The enthalpy change of the reaction is ΔH = -297 kJ/mol. This burning of sulfur reaction is exothermic in nature and this combustion can produce temperature of upto 1000 °C or more.

Sulfur in the elemental state oxidises and changes its oxidation number from 0 to +4 and oxygen reduces and changes its oxidation number from 0 to -2.

Balanced chemical equation: S(s) + O₂(g) → SO₂(g).

Sulfur change oxidation number from 0 to +4 (oxidation) and oxygen change oxidation number from 0 to -2 (reduction).

Sulfur dioxide (SO₂) is very common volcanic gas.

Fossil fuel combustion increases the acidity of rain because the sulfur dioxide is produced.

Because of fuel combustion, sulfur dioxide goes up into the atmosphere as the hot gases rise, than it reacts with water and oxygen in the air and form sulfuric acid.

Answer:

Independent variable, is the amount of salt water received by each plant

Dependent variable, is the height of each plant

Control group, is the fourth plant that received pure water.

Note: The question is incomplete. The complete question is as follows: For the following experiments, define the independent variable (IV), dependent variable (DV) and control group (CG).

2. You water three sunflower plants with salt water. Each plant receives a different concentration of salt solutions. A fourth plant receives pure water. After a two-week period, the height is measured.

Explanation:

Independent variable: An independent variable is a variable that an experimenter changes or controls and which has a direct effect on the dependent variable.

In the experiment above, the independent variable is the amount of salt water received by each plant because it is under the control of the experimenter and also is thought to have a direct effect on the height of plants.

Dependent variable: A dependent variable is a variable that is being measured or studied in an experiment, and it depends on the independent variable for its results.

The height of the plants is the dependent variable as it depends on the amount of salt water the plant receives.

Control group: The control group is the group in an experiment or study that does not receive the treatment as the other groups being studied and as such, is not influenced by the independent variable. Therefore, it is used as a standard for the other groups under study.

In this experiment, the control group is the fourth plant that received pure water.

Use the following table to answer the question. Strong acids Weak acids Weak bases Strong bases HBr CH3COOH NH3 NaOH HCl HF NH4O

Y_Kistochka [10]

Answer: The salt which has the highest pH is $CH_3COONa$

Explanation: Salts are formed by the reaction of acid and base. General equation for the generation of salt is given by:

$HX+BOH\rightarrow BX+H_2O$

The given salts are formed from the reaction of acids and bases.

1) $K_2SO_4$

This is a salt formed by the reaction of strong base (KOH) and strong acid $(H_2SO_4)$ . So, this salt is a neutral salt.

$H_2SO_4+2KOH\rightarrow K_2SO_4+2H_2O$

2) $CuSO_4$

This is a salt which is formed by the reaction of weak base $(Cu(OH)_2)$ and strong acid $(H_2SO_4)$ . So, this salt is an acidic salt.

$H_2SO_4+Cu(OH)_2\rightarrow CuSO_4+2H_2O$

3) $NH_4Cl$

This is a salt which is formed by the reaction of weak base $(NH_3)$ and strong acid (HCl). So, this salt is an acidic salt.

$HCl+NH_3\rightarrow NH_4Cl$

4) $CH_3COONa$

This is a salt which is formed by the reaction of strong base (NaOH) and weak acid $(CH_3COOH)$ . So, this salt is a basic salt.

$CH_3COOH+NaOH\rightarrow CH_3COONa+H_2O$

Now, we have to find the salt which has the highest pH value.

Highest pH value means that the salt must be basic in nature and from the given salts, only $CH_3COONa$ is basic salt. Hence, this salt has the highest pH value.
