C-12? (6 protons) C-13? (6 protons) C-14? (6 protons)
Answer:
Yes.
Explanation:
Yes, the change in cuvette lead to a determinate error in the analysis if the different cuvette is used for the analysis because the amount of liquid sample that is used has different volume. If both cuvette are of the same type and has no difference in their structure and size then there is error occurs in the analysis but if both cuvette are different from one another then the error will occur in the analysis. because the amount of liquid that is used has different volume.
Answer:
Number of moles of oxygen used=13.5moles
Explanation:
To know the number of moles of oxygen used, first calculate the molar mass of water.
H2O=(2*1)+(1*16)
=2+16
18g/mol of H2O
The moles of H2O is 7.6 moles
So first, find the molar mass of oxygen
O2=2*16
=32g/mol
Then, number of moles of oxygen is equal to molar mass of oxygen divide by the molar mass of water times the number of moles of water
No. moles of O2=[32g/mol]/[18g/mol] *7.6moles
Moles of O2=1.778*7.6moles
No.moles of O2=13.5 moles
Therefore, the number of moles of oxygen used was 13.5moles
<em>Answer:</em>
- At 60 centigrade, the kinetic energy of the substance will be greatest.
<em>Explanation:</em>
As we know, the kinetic energy of substance is directly proportional to Temperature.
The total Kinetic energy can be calculated as follow
K.E = 3/2 n.R.T
From the equations, it is cleared that Temperature is directly proportional to temperature.
If it is Mg2N2, and the limiting element is Mg, then the mass of Mg2N2 that can be produced is 50g/2 = 25 grams.
if it is Mg3N2, then the mass is 50/3 = 16.67grams.
