<u>Answer:</u> When oppositely charged species interact.
<u>Explanation:</u>
Ionic compound is defined as the compound which is formed by the complete transfer of electrons from one element to another element.
In these compounds, oppositely charged ions are attracted towards each other to form a compound.
<u>For Example:</u> NaCl is formed by the attraction of 
ions. So, same number of oppositely charges maintain electrical neutrality.
Electrical neutrality in a compound is achieved when atoms forming a compound have same number of opposite charges. Basically the charges on cation is balanced by the charges on anion.
Molarity of solution = 0.08 M
<h3>Further explanation </h3>
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
Where
M = Molarity
n = number of moles of solute
V = Volume of solution
Volume of solution = 100 ml + 150 ml = 250 ml
Answer:
90 Thymine bases
Explanation:
Chargaff's rules states that in the DNA of any organism, the amount of purine and pyrimidine bases must be in a 1:1 ratio. This means that the amount of Adenine and Guanine bases (purines) should be equal with their complementary pairs of Thymine and Cytosine bases respectively (pyrimidines). (A = T) + (G = C) = 100
Hence, according to this question, if there are 60 cytosine bases, this means that there will be 60 Guanine bases. 60 C + 60 G = 120 pyrimidines
300 total bases - 120 pyrimidine bases = 180 purine bases.
180/2 = 90 equal bases of Adenine and Thymine. Hence, Thymine bases will be 90.
Answer:
Population of duck and frog will change with the change
Explanation:
The complete question is
Scientists are studying animals in a large lake area. In this lake area, both owls and raccoons eat ducks, and ducks eat frogs. The data shows that recently the size of the raccoon population decreased. How will the decrease in the raccoon population affect the other populations? Be sure to explain whether the owl population, the duck population, and the frog population will change, and why.
- Owl population will change
-
Duck population will change
-
Frog population will change
Solution
Raccoon eat duck and duck eat frog. Now if the population of Raccoon decreases then the number of predators of duck will decrease thereby increasing the population of duck.
The higher will be the number of ducks, the more frogs they will consume thereby decreasing the population of frogs
Hence both the population of duck and frog will change with the change
The liquids hexane
and water are placed in a test tube. The test tube is stoppered, shaken, and
placed in a test tube rack. The liquids separate into two distinct
layers because hexane and water have different molecular polarities. The answer
is number 2.
