The two different mineral elements that a fertilizer can contain are:
- Phosphorus - build up of nucleic acid and ATP
- Nitrogen- synthesis of proteins
<h3>What are fertilizers?</h3>
Fertilizers are chemical substances added to the soil in order to improve crop growth and development.
Fertilizers are artificially made to contain mineral elements that are needed by the plants. Some of the mineral elements are as follows:
- Phosphorus
- Nitrogen
- Pottasium
- Phosphorus helps in the build up of nucleic acids and ATP for energy.
- Nitrogen is useful in the synthesis of proteins.

Answer:
Filled below
Explanation:
#v.e means number of valence electrons.
Also, the column total v.e is gotten by adding the v.e of the metal to the v.e of the non metal based on the chemical formula of both of the 2 elements combined.
K: Cl: 5; KCl; 1 + 5 = 6
Be: S: 6; BeS; 2 + 6 = 8
Na: F: 7; NaF; 1 + 7 = 8
Mg: Se: MgSe; 2 + 6 = 8
Al; N; AlN; 1 + 5 = 6
Be; F; BeF2; 2 + 2(7) = 16
Mg; N; Mg3N2; 3(2) + 2(7) = 20
Answer: The new volume of gas is 28.5 L
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 1.00 atm (at STP)
= final pressure of gas = 102.6 kPa = 1.01 atm (1 kPa= 0.0098 atm)
= initial volume of gas = 10.0 L
= final volume of gas = ?
= initial temperature of gas = 
(STP)
= final temperature of gas = 
Now put all the given values in the above equation, we get:
The new volume of gas is 28.5 L
The correct answer is option B. The amphibian and mosses belonged to the same age.
Since the rocks belong to the same age and one contain fossils of an amphibian and the other containing fossils of mosses, it is very likely that both the amphibian and the mosses existed at the same time.
Sedimentary rocks generally have fossils in them and it is very easy to determine the age of the fossils from Radiometric Dating using radioactive carbon C¹⁴. However, before the complete understanding of radioactive decay fossil, age was determined by studying the succession of fossils on old to younger sedimentary rocks.
