Answer:
the sample undergo 
disintegrations per second.
Explanation:
Given:
The amount of sulphur purchased is 0.671 μCi
To find:
disintegrations per second = ?
Solution:
Some of the conversions are
1 rad = 0.01 Gy
1Gy = 1 j/kg tissue
1 rem = 0.01 Sv
1Sv = 1 j/Kg
Using these conversions,
The decay rate of this sample is calculated as
= disintegrations per second
The chemical formula for zinc is Zn, and HCl for hydrogen chloride. The complete balanced equation for these reactants would be:
Zn + 2 HCl → ZnCl₂ + H₂
The stoichiometric coefficient 2 for HCl is essential to obey the Law of Conservation of Mass. The elements before and after the reaction must be equal in amounts.
Answer:
The answer to your question is: Q = 3153600 Joules
Explanation:
Data
Q = ?
m = 48 kg
T1 = 21°C
T2 = 94°C
Cp = 900 J/g°C
Formula
Q = mCpΔT
Q = (48)(900)(94 - 21) = 3153600 Joules
