Rdaioactive decay results in the formation of a different element. Plutonium decays by emitting alpha emission to form uranium. Thermal energy is emitted as the alpha particles are absorbed and the kinetic energy is converted to heat. The amount of energy is computed by the formula;
E = mc²
E = 0.000046 × (3 ×10^8)
Energy = 4.14 ×10^13 Joules
Answer:
studies
Explanation:
if they get plenty of studies then they get it
The correct formula for hydrogen gas is H2
Answer:
We know that, composition of HNO3 is Hydrogen, Nitrogen and oxygen. Total number of atoms = 3+1+1=5 atoms are present in 1 molecule of HNO3.
Answer:
There are 55, 49 g of CaCl2
Explanation:
We calculate the weight of 1 mol of CaCl2:
Weight CaCl2=Weight Ca + 2x(Weight Cl)= 40,08g+ 2x 35, 45g=110,98 g/mol
1000ml-----2 mol of CaCl2
250ml------x= (250 ml x 2 mol of CaCl2)/1000ml= 0,5 mol of CaCl2
1mol -----110,98g
0,5mol ---x= (0,5molx110,98g)/1 mol= <em>55,49 g</em>
