Answer:
Explanation:
By Ideal Gas Law, P1*V1 / T1 = P2*V2 / T2
So new pressure = (P1*V1 / T1) / (V2 / T2)
= P1*V1*T2 / T1*V2
= 800*3.6*298 / 250*1.8
= 1907.2 mmHg
Answer:
0.2 mol
Explanation:
Use the given values to find the molar mass. The molar mass is 40 g/mol.
23 + 16 + 1 = 40
Using the molar mass, convert grams to moles.
(8 g)/(40 g/mol) = 0.2 mol
You have 0.2 mol of sodium hydroxide.
My teacher just explained this problem to me and she said it is "the same".
Answer : Gain of electrons.
Explanation : In a oxidation-reduction reaction often called as redox reactions, during the process of reduction the electrons are gained by the reduced species in the chemical reaction, whereas in the oxidation process the electrons are lost by the oxidised species. The total transfer of electrons forms the base of the redox reactions.
Redox chemical reactions are those where the oxidation states of atoms are changed.
