Answer:
Regularly test the water in residents' homes.
Explanation:
The only way to know if tap water contains lead is to do tests to determine the levels of that metal in the water. Therefore, the state is under an obligation to constantly conduct such tests in the resident´s homes and thus determine whether the water supplied is fit for human consumption.
The state after the tests must guarantee the population the treatment of the water to reduce the levels of lead. The main pipes that contain lead pipes must be changed, as well as those parts of the service connections made of lead.
15 is the group that phosphorus is found in.
The formula of Aldehyde is represented by <span>C2H4O. It has two atoms of Carbon, four atoms of hydrogen and one atom of oxygen. Aldehyde is an organic compound. It's organic because it contains carbon. It has a structure of R-CHO, that consists a carbonyl center bonded to R group and to hydrogen.</span>
Answer:
90%
Explanation:
Percentage yield = ?
Theoretical yield = 50g
Actual yield = 45g
To calculate the percentage yield of a compound, we'll have to use the formula of percentage yield which is the ratio between the actual yield to theoretical multiplied by 100
Percentage yield = (actual yield / theoretical yield) × 100
Percentage yield = (45 / 50) × 100
Percentage yield = 0.9 × 100
Percentage yield = 90%
The percentage yield of the substance is 90%
Answer:
The component that dissolves the other component is called the solvent. Solute – The component that is dissolved in the solvent is called solute
