*10 points!* A scientist wants to know if fertilizer helps plants grow faster. She adds fertilizer to 50 plants regular soil. She keeps 50 plants in the same regular soil. She predicts that those receiving fertilizer will grow faster. They are plant in the type of container, temperature, and water amount. She carries the experiment for 10 months. Using the above information identify the following:
1. Hypothesis
2. Control group
3. Experimental group
4. Independent Variable
5. Dependent Variable
6. Constants
7. What can be done to improve the validity of the experiment

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
