The emission of a beta particle has the effect of : C. No change in mass
basically, beta particle has a very very little mass compared to the proton and neutrons, so little to the point that it never considered as a change in mass. But it does decreases the charge of atom
hope this helps
The concentration as % by mass is calculated as below
mass of solute/mass of solvent x100
mass of solute(sugar) = 4g
mass of solvent(water) =46 g
= 4g/ 46 g x100 = 8.7%
Answer:
H3PO4 + 5 HCl → PCl5 + 4 H2O
Explanation:
The given equation is
H3PO4 + HCl = PCl5 + H2O
The above chemical equation has one P atom on both the sides, hence phosphorus is balanced
There are 5 Cl on the RHS but only one Cl on the LHS. On balancing the chlorine, we get -
H3PO4 + 5HCl = PCl5 + H2O
Now, there are 8 hydrogen atom on the LHS but only two on the RHS. On balancing the hydrogen on both the sides, the new equation become
H3PO4 + 5HCl = PCl5 + 4H2O
Let us check for oxygen
Oxygen on LHS = 4 and oxygen on RHS = 4
Thus, the balanced equation is H3PO4 + 5HCl = PCl5 + 4H2O
