Answer:
CaF2
Explanation:
Calcium fluoride is a solid formed by the chemical combination of Calcium (Ca) and Fluorine (F). Two molecules of fluorine (F2) and one molecule of Calcium (Ca) are needed to form the Calcium Fluoride molecule.
An ionic bond is formed between the Calcium and Fluorine atoms i.e. electrons are transferred from calcium atoms to fluorine atoms. The calcium ion is a cation with formula; Ca2+ while fluorine is an anion with formula; F-. Hence, it takes two molecules of Fluorine ion (F-) to form a relatively stable and neutral molecule with 1 molecule of Calcium ion (Ca2+).
Depends if the reaction is endo or exo thermic
Endothermic reaction
Increasing the temperature will shift the equilibrium to the right-hand side of the equilibrium. to oppose the change in temperature.
Exothermic reaction
Increasing the temperature will shift the equilibrium to the left-hand side of the equilibrium. to oppose the change in temperature.
Hope that helps
Hello there!
<span>A vegetable garden is 12 meters long by 7 meters wide. It is home 168 mice. What is the population of the mice.
</span>
The size of the vegetable garden is just extra information.
The only information we need is: "<span>It is home 168 mice"
This means the population of mice is 168. Meaning, there are 168 mice living there.
I hope I helped!
Let me know if you need anything else!

If a bacterial protein contains 150 amino acids, then there would be 150 codons in the specification to construct the said protein. A codon is definces as a sequence of 3 RNA or DNA nucleotides which would correspond to a specific amino acid such that if you have 150 amino acids then you would also have 50 codons. THe start of a codon is the first codon that can be found in the messenger RNA that is translated by the ribosome.
