Answer:
transmutation, conversion of one chemical element into another. A transmutation entails a change in the structure of atomic nuclei and hence may be induced by a nuclear reaction (q.v.), such as neutron capture, or occur spontaneously by radioactive decay, such as alpha decay and beta decay .
Answer:
Explanation:
Given that,
Mass of the sample, m = 275 g
It required 10.75 kJ of heat to change its temperature from 21.2 °C to its melting temperature, 327.5 °C.
We need to find the specific heat of the metal. The heat required by a metal sample is given by :
c is specific heat of the metal
So, the specific heat of metal is 
.
0.5 litres contain 1.1 moles
therefore 1 litre will have= 1*1.1/0.5
molarity=2.2M
Answer is: <span>the percent yield for this reaction is 75,37%.
</span>m(MgCl₂) = 962 g.
n(MgCl₂) = m(MgCl₂) ÷ M(MgCl₂).
n(MgCl₂) = 962 g ÷ 95,21 g/mol.
m(MgCl₂) = 10,1 mol.
n(MgCl₂) : n(Mg) = 1 : 1.
n(Mg) = 10,1 mol.
m(Mg) = 10,1 mol · 24,3 g/mol.
m(Mg) = 245,43 g.
ω(Mg) = 185 g ÷ 245,43 g · 100% = 75,37%.
