Silver. It is number 47 on the periodic table meaning it has 47 protons. It’s atomic mass is 108. 47+61=108 so it is definitely silver
Answer: 780 kcal are required to produce 12.00 mol of
Explanation:
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and written along with reactants.
The balanced chemical reaction is:
According to stoichiometry :
2 moles of are produced by absorption of energy = 130 kcal
Thus 12.00 moles of are produced by absorption of energy =
Thus 780 kcal are required to produce 12.00 mol of
Answer:
Plastic ma be a homogeneous mixture
Explanation:
as the homogeneous mixture are the equal ration blended solution so plastic are also blended in equal proportion with the help of molten state
<h3>
Answer:</h3>
Wavelength-1.805 × 10^-12 m
Type of electromagnetic radiation-Gamma rays
<h3>
Explanation:</h3>
We are given the following;
Energy of a photon is 1.10 × 10^-13 Joules
We are required to calculate the wavelength's of photon
We need to know that the energy of a photon is calculated by the formula;
E = hf, but f = c/λ
Therefore;
E = hc/λ , where h is the plank's constant,6.623 × 10^-34 J-s, c is the speed of light, 2.998×10^8 m/s and λ is the wavelength.
Rearranging the formula;
λ=hc/E
Thus,
λ = (6.623 × 10^-34 J-s × 2.998×10^8 m/s) ÷ 1.10 × 10^-13 J
= 1.805 × 10^-12 m
- Therefore, the wavelength of the photon is 1.805 × 10^-12 m
- The most probable electromagnetic wave with the wavelength 1.805 × 10^-12 m is gamma rays
- This is becasue the wavelength of gamma rays is less than 1 nm or 10^-9 m
