Explanation:
Oogenesis can be defined as a process of differentiation of egg cell (ovum), into a mature ovum that further develops after fertilization. In humans, oogenesis begins in the early stage of embryonic development, during whcih primary oocyte performs meiosis I and forms secondary oocyte.
<u>Answer:</u> The chemical equation is 
<u>Explanation:</u>
There are 2 types of reactions that are classified based on enthalpy change:
- Endothermic reaction
- Exothermic reaction
Endothermic reactions: They are defined as the reactions where heat is absorbed by the reaction. The change in enthalpy of the reaction is always positive.
Exothermic reactions: They are defined as the reactions where heat is released by the reaction. The change in enthalpy of the reaction is always negative.
Given values:
Energy released for 1 mole of HCl reacted = -42.1 kCal
The chemical equation for the formation of ammonium chloride follows:
Answer:
C
Explanation:
The nucleus contains protons and neutrons, electrons are located in outer electron cloud.
Answer:
P(total) = 15 atm
Explanation:
Given data:
Pressure of O₂ = 5.75 atm
Pressure of N₂ = 7 atm
Pressure of He = 2.25 atm
Total pressure inside tank = ?
Solution:
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(O₂) + P(N₂) + P(He)
P(total) = 5.75 atm + 7 atm + 2.25 atm
P(total) = 15 atm
