Answer:
0.01 M
Explanation:
The chemist is performing a serial dilution in order tyo obtain the calibration curve for the instrument.
First we must obtain the concentration of the solution in the 250ml flask from
C1V1 = C2V2
Where;
C1 = concentration of the stock solution
V1 = volume of the stock solution
C2 = concentration of the diluted solution
V2= volume of the diluted solution
2.61 × 10 = C2 × 250
C2 = 2.61 × 10/250
C2 = 0.1 M
Hence for solution in 100ml flask;
0.1 × 10 = C2 × 100
C2 = 0.1 × 10/100
C2 = 0.01 M
Answer:
1. the effects of punishment.
Explanation:
Stanley Milgram (1933 - 1984) was a graduate American psychologist at Yale University who conducted the Little Worlds Experience (the source of the concept of the six degrees of separation) and the Milgram Experience on obedience to authority.
Milgram was interested in researching how far people would go in obeying an instruction if it involved harming another person.
The study aimed to observe how easily ordinary people could be influenced into committing atrocities.
The first one is the 2Hg+.....
The second is the Ca+ 2H2O....
The third is the first one, H2 + Cl2...
And the last is Fe+ S= FeS
It was so easy
Good Luck
Answer:
D. Is the correct option.
Explanation:
2p level contains the electrons furthest from the nucleus in the case of Nitrogen thus it's much easier to disperse/remove the electrons from the shell due to low pull of nucleus energy.
53.5 g MgCl2 /95.21 g/mol = 0.5619 Moles MgCl2. Since the ratio is 3MgCl : 2Na3PO4 you multiply 0.5619 x 2/3 (since you're solving for NaPO, the 2 goes on top) which shows we have .3746 Moles of NaPO. Multiply times it's molar mass so 0.3746x 163.94g/mol= 61.4136 grams NaPO. I believe.
