There are two types of change in matter: physical change and chemical change. ... This is called the Law of Conservation of Matter. It states that matter can never be created or destroyed, only changed and rearranged.
Answer:
9.069 KW
Explanation:
The heat engine operates in a carnot cycle between 75°C to 492°C so the lower temperature and the higher temperature
Efficiency of the carnot cycle
We know that
it is given that duration of each cycle is 1.16 sec so power output
Niobium 97
Explanation:
When a substance undergoes beta decay, the mass number of such nuclei remains the same but the atomic number increases by 1.
A beta particle is denoted as ⁰₋₁β
Zirconium ₄₀⁹⁷Zr
Niobium ₄₁⁹⁷Nb
The decay reaction is shown below:
₄₀⁹⁷Zr → ₄₁⁹⁷Nb + ⁰₋₁β
From the equation above, we can deduce that both mass and atomic numbers are conserved;
Mass number: 97 = 97 + 0; 97 = 97
Atomic number: 40 = 41 - 1; 40 = 40
