Answer:
CH3Br ( Methyl Bromide )
Explanation:
H9 C3 Br3 => rewrite as: C3H9Br3 => actually, this is 3 moles of molecule CH3Br !
C3H9Br3 ~ 3( CH3Br)
I hope this answer can help you. Have a nice day!
Answer : The specific heat of tin is, 0.213 J/g.K
Explanation :
Formula used :
where,
q = amount of heat lost = -399.4 J
c = specific heat capacity of tin = ?
m = mass of tin = 25.0 g
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
Therefore, the specific heat of tin is, 0.213 J/g.K
Yes, because if you have a flower and it reproduces then there's a HIGH chance that the next flower will be the same color because of traits! <span />
Answer:
The correct answer is KNO3
Explanation:
Pb(NO3)2 +2 KCl -> PbCl2 + KNO3
If we look at the left side of the equation we could see that there are 1 lead atom, 2 nitrate atoms ,2 potassium atoms and 2 chlorine atoms
Now when we look at the right side of the equation, we found that there are –
1 lead atom and 2 chlorine atoms (PbCl2) , thus lead and chlorine are balanced as they have the same number of atom in LHS and RHS
There is only 1 potassium and 1 nitrate atom on RHS , thus KNO3 is not balanced.
The balanced equation would be –
Pb(NO3)2 +2 KCl -> PbCl2 +2 KNO3
