Answer:
number of protons, mass and atomic number
Explanation:
Answer:
Pb(NO3)2+2NaCl \to PbCl2+NaNO3
Explanation:
Lead(II) nitrate is 
Sodium Chloride is 
This is a double displacement reaction. Hence anions or cations of both the compounds are displaced to form the products.


Therefore the balanced equation is

Answer:
In percentage, the sample of C-4 remains = 0.7015 %
Explanation:
The Half life Carbon 14 = 5730 year
Where, k is rate constant
So,
The rate constant, k = 0.000120968 year⁻¹
Time = 41000 years
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
So,
<u>In percentage, the sample of C-4 remains = 0.7015 %</u>
Answer:
PbBr2 + 2HCl → 2HBr + PbCl2. Reaction Information. Lead(Ii) Bromide + Hydrogen Chloride = Hydrobromic Acid + Cotunnite. Reaction Type.
