Answer:
2.8087*10^-12 kJ per mole of reaction (2.8087*10^-12 kJ/mol).
Explanation:
To calculate the energy produced, we need to write a balanced equation for the reaction and determine the change in the masses of the reactants and products. Afterward, we can use the energy equation to determine the energy produced. The balanced equation for the nuclear reaction is shown below:
³₁H + ²₁H ⇒⁴₂He + ¹₀n
The masses of atoms are ³₁H is 3.01605 amu, ²₁H is 2.0140 amu, ⁴₂He is 4.00260 amu, and ¹₀n is 1.008665 amu.
change in mass Δm = (3.01605+2.0140) - (4.00260+1.008665) = 0.0188 amu
Energy produced, E = m*C^2
C is the speed of light = 3*10^8 m/s and 1 amu = 1.66*10^-27 kg
Therefore:
E = 0.0188*1.66*10^-27 * (3*10^8)^2 = 2.8087*10^-12 kJ per mole of reaction.
Therefore, in scientific notation, the energy released is 2.8087*10^-12 kJ/mol
Answer:
Element; compound
Explanation:
Oxygen is an element on the periodic table, but when it's combined with the element Hydrogen, it produces water, which is a compound (H2O). When two elements combine, it produces a compound.
I hope this helps! :)
Answer:
41.2 lb/gal
Explanation:
Step 1: Given data
Density of iodine: 4.94 g/mL
Step 2: Convert the mass to grams
We will use the conversion factor 1 lb = 454 g.
4.94 g/mL × (1 lb / 454 g) = 0.0109 lb/mL
Step 3: Convert the volume to gal
We will use the conversion factors 1 gal= 3.785 L and 1 L = 1,000 mL.
0.0109 lb/mL × (1,000 mL/1 L) × (3.785 L/1 gal) = 41.2 lb/gal
