How do you find density?
Well, first D=m/v
D=density
M=mass
V=Volume
Volume of cube: 3*3*3=9cm cubed
Mass of cube: 25g
D=25g/9cm cubed
<span>2.8 g/cm cubed is the answer.
Hope this helps!</span>
It represents a chemical change
Answer:
11 atoms
Explanation:
The formula for lead(II) bicarbonate is: Pb(HCO3)2.
Atoms in Pb(HCO3)2:
Pb=1, H=1×2, C=1×2, O=3×2
1+1×2+1×2+3×2
=1+2+2+6
=11 atoms
The radiation emitted is a beta particle with a -1 charge. <span>Beta particles have a </span><span>medium penetrating power. An emission of beta particles requires shielding because of the hazards it pose to humans. Thus, one characteristic of this radiation is that some shielding is required.</span>
