Chlorine has 7 valence electrons. With what group of elements will chlorine most readily bond?.
The elements that chlorine will most readily bond with are elements found in group one eg sodium, potassium, etc.
What is group of elements?Elements are arranged in groups in the periodic table based on their number of valance electrons.
Elements in the same group of the periodic table has similar characteristics.
Reaction between metals and nonmetalsWhen metals react with non-metals, electrons are transferred from the metal atoms to the non-metal atoms, forming ions.
The resulting compound is called an ionic compound.
Chlorine is the most reactive non metal and will bond easily with metals. The most reactive metals are found in group one.
Example of chlorine reaction with a group one elementCl⁻ + Na⁺ -------> NaCl
Thus, the elements that chlorine will most readily bond with are elements found in group one eg sodium, potassium, etc.

Kiera and Grace are sisters. They both have blue eyes. Kiera is extremely short for her age and Grace is exceptionally tall for her age. Develop a hypothesis as to why the sisters have different statures. Justify your hypothesis in two or more complete sentences.
The hypothesis as to why the sisters have different statures occurs because from genetics we know that it is linked to the alleles so one sister is shorter than the other one was they had different alleles.
What is the genetic similarity between siblings?On average, siblings share about 50% of their DNA with each other, but some siblings share even more and some less. So while we all have approximately 50% DNA from each parent, the segments we end up getting are completely random.
Hereditary character or gene that is manifested by the absence of the opposite gene, called dominant, in this case, Kiera is extremely short for her age.

B) Which
brand of fertilizer (A,B or C) works the best?
C)
Which amount of fertilizer will show the most
growth?
D) What level of fertilizer is the most that
can be given before growth decline?
Answer:
A) Which brand and amount of fertilizer will work best?
Explanation:
A) is the best answer because it takes into account all of the variables. The variables seem to be the amount of fertilizer, average plant growth, and brand of fertilizer. The independent variables are amount of fertilizer and fertilizer brand. The dependent variable is the plant growth.
B) is not the best answer because it does not include the amount of fertilizer. Because this variable is changing, it is important to consider.
C) is not the best answer because it does not take the type of fertilizer into account. If the researcher were only concerned with how the amount of fertilizer affects plant growth, it would not be necessary to include 3 different types of fertilizer.
D) is not the best answer because this doesn't explain why the researcher used different types of fertilizer.

Answer:
4 2/3 days
Explanation:
31.25 = 250 ( 1/2)^n solve for n
31.25/250 = 1/2 ^n log both sides to find n = 3 half lives
14 days = 3 half lives

Atoms are the unit of the molecule of the compound. The 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water and 3 moles of carbon dioxide in the sample.
What are atoms?Atoms are the smallest fundamental unit of the compounds that can be given by Avogadro's number.
For calculating the oxygen atoms in 5 mole water:
If 1 mole = 6.02 × 10²³
Then, 5 moles = 5 × 6.02 × 10²³
Hence, 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water.
Moles of carbon dioxide in the sample is calculated as:
If 1 mole of carbon dioxide = 6.02 × 10²³ molecules
Then moles in 1.8 x 10²⁴ molecules will be,
(1.8 x 10²⁴ molecules) ÷ (6.02 × 10²³ molecules) = 3 moles
Hence, 3 moles of carbon dioxide is present in the sample.
