Answer:
The same number of atoms of each element must appear on both sides of a chemical equation. However, simply writing down the chemical formulas of reactants and products does not always result in equal numbers of atoms. You have to balance the equation to make the number of atoms equal on each side of an equation.

Hi!
The substance that could be found in air, water or soil that is harmful to humans or animals is called pollutant.
Pollutants are the only harmful substances that can be found in these three places. Carbon Dioxide (CO₂) is commonly found in the air, fossil fuels are found in soil and water and smog is found in the air. Only pollutant can be found in these three places as there are varied in its chemical structure. Common pollutants include Sulfur Dioxide (SO₂) which can be found in the air, and Lead, which can be found in water or soil.
Have a nice day!
Answer:
1.35 m
Explanation:
We can solve this problem by using the <em>freezing point depression formula</em>:
Where:
- ΔT is the temperature difference between the freezing point of the pure solvent (water) and the solution. In this case it is (<em>0 °C - -2.5 °C = 2.5 °C</em>).
- Kf is the cryoscopic constant, <em>for water it is 1.853 °C*kg/mol.</em>
- i is the van't Hoff factor, <em>as sugar does not dissociate in water, it has a value of 1</em>.
We <u>input the data</u>:
- 2.5 °C = 1.853 °C*kg/mol * m * 1
And <u>solve for m</u>:
