Answer:
Volume and density are inversely related
Answer:
Explanation:
1. Increasing the concentrations of reactants in a chemical reaction would affect a reaction positively by increasing the number of collisions within a particular period which in turn increases the rate of reaction.
2. The molecules gains energy,which enable them to move faster and collide with the right energy for a reaction to take place.
3. The average kinetic motion of molecules in a solution can be measured by measuring the temperature. Temperature is a measure of the average kinetic energy of molecules in a solution.
The chemical formula is CaC2
Answer:
The concentration of impurities in the filtered water is 33 ppm.
Explanation:
Initially, the concentration of impurities is 330 ppm. If the filter removes 90% of impurities, then only 10% of the original impurities remain in the filtered water. Therefore, their concentration will be 10% of 330 ppm, that is, 33 ppm.
