Answer:
Explanation:
NaCl does not contain molecules
Answer:
A
Explanation:
The molecule with the strongest intramolecular bond is HF. Hydrogen fluoride is the answer due to the strong and highly electronegative nature of Fluorine.
- Fluorine is the most electronegative element in nature.
- When it combines with other substances, due to its electronegative property, it draws most of the electrons closest to itself in the bond.
- This tendency and ability makes the shared electrons closer the fluorine in the bond.
- The strong polarization that ensues confers a very strong covalent bond pair on the bond formed.
Answer:
The chemical equation needs to be balanced so that it follows the law of conservation of mass.
Explanation:
Answer:
This question will be answered based on general understanding of how a controlled experiment should be:
The answer is: We must make sure we are testing/changing only one variable, and controling others
Explanation:
A controlled experiment is an experiment in which the independent variable is changed for a particular group called the EXPERIMENTAL group and unchanged for another group called the CONTROL group.
In a controlled experiment, only one variable should be tested while the others should be kept constant in order to have an effective result or outcome. This is the case in this question, the type of music or soil should be unchanged for each plant because the experimenter must make sure that he/she is testing/changing only one variable, and controling others.
