An element from Group 2 will form ionic bonds with a nonmetal, Groups 13-17
Explanation:
An ionic bond is formed between a "metal and non-metal". The valence electrons are lost in one and gained in the other atom. It involves electrostatic forces between the two ions which are of opposite charges.
When one atom(metal) losses an electron, it becomes a "positive ion". Similarly, when the other atom(non-metal) gains an electron it becomes a negative ion. For example: The formation of NaF(Sodium Fluoride).
The dependent variable is 'Number of plants' which is the correct answer.
The independent variable is CO₂ levels in ocean water, however, the growth of plants in ocean water depends on the CO₂ levels. Higher CO₂ is level is conducive to the growth of plants.
Plants use CO₂ and water in photosynthesis to prepare food in the presence of light.
6CO₂ + 6H₂O + light energy = C₆H1₁₂O₆ + 6O₂.
No it shouldn't! These Vaccinations are being pumped into us and do we even know what they are really doing?!?!?
