The hormone that promotes active tubular secretion of potassium ions into, along with sodium absorption from filtrate in the distal convoluted tubule and collecting duct is Aldosterone. This hormone is produced by the adrenal gland and acts mainly in the functional unit of the kidney to aid in the conservation of sodium, secretion of potassium, water retention and to stabilize blood pressure. It indirectly regulates blood levels of electrolytes and helps to maintain the blood pH.
Given :
2 Mg + O₂ → 2 MgO
To Find :
How many moles of magnesium oxide are formed if you burn a 2.3 mol sample of magnesium ribbon in the air.
Solution :
From given balanced chemical reaction we can see that 2 mole of Magnesium reacts with 1 mole of O₂ to produce 2 mole of MgO.
Since, there is abundance of oxygen in air.
Therefore, 2.3 moles of magnesium will produced 2.3 moles of magnesium oxide.
Answer: The forces of attraction are stronger in new attractions that are formed.
Explanation:
When a chemical reaction takes place between two or more different compounds then less reactive substance is displaced by the more reactive substance.
During this process, when bonds are broken between the reactants then it means the force of attraction is less stronger. The formation of new compounds occur because force of attraction is more in these new substances due to which its atoms come closer to each other.
Thus, we can conclude that forces of attraction are stronger in new attractions that are formed.
I think it’s hydrothermal vents, rifts and subduction trench
Explanation:
It is known that 1 gram contains 1000 milligrams. And, mathematically we can represent it as follows.
or 
So, when we have to convert grams into milligrams then we simply multiply the digit with 1000. And, if we have to convert a digit from milligrams to grams then we simply divide it by 1000.
