The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. This is because molecules can only complete the reaction once they have reached the top of the activation energy barrier.
Answer: B. meiosis
Explanation: Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell? divides twice to form four daughter cells.
Like transpiration in plants mammal's hypothalamus makes sweat glands functional and mammal's body secretes sweat which on evaporation decreases the body temperature
For the cell cycle to be out of control refers to cancer which is the abnormal growth of cells. Cancer and the cell cycle can be connected because cancer interrupts the natural cell cycle process.
Answer:
Dissolve 11.7 grams of NaCl in 500 ml of water and it will give 0.4 M NaCl solution.
Explanation:
As we know that
Thus the number of moles of NaCl required to form 0.4 molar solution are
the volume given is 500 ml
= 500/1000 liter = 0.5 liter
putting the values
We also know that one mole of NaCl = 58.5 grams thus 0.2 moles
= 58.5 × 0.2 = 11.7 grams
THUS dissolve 11.7 grams of NaCl in 500 ml of water and it will give 0.4 M NaCl solution.
