Answer:
852000 J
Explanation:
The following data were obtained from the question:
Mass (M) = 600 g
Change in temperature (ΔT) = 2 °C
Specific heat capacity (C) = 710 J/g℃
Heat transfered (Q) =?
Thus, we can obtain the the heat transfered to the diamond by using the following formula:
Q = MCΔT
Q = 600 × 710 × 2
Q = 852000 J
Therefore, the energy transfered to the diamond by heat is 852000 J
Answer: Option (a) is the correct answer.
Explanation:
It is known that elements which have completely filled octet when they are present in neutral state then they do not need to gain or lose an electron. Hence, the element becomes unreactive in nature.
For example, neon is a noble gas whose atomic number is 10 and its electronic distribution is 2, 8. As they have completely filled orbitals so they do not react with other elements.
As a result, they are rarely found in combination with other elements.
Thus, we can conclude that the Group 8A(18) elements are unreactive and are rarely found in combination with other elements.
Energy is released as a bond is formed
Answer:
They all end up in the oceon

Answer:
The outer shell of the new star will start to expand.
Explanation:
The new star will continue to glow for millions or even billions of years. As it glows, hydrogen is converted into helium in the core by nuclear fusion. The core starts to become unstable and it starts to contract. The outer shell of the star, which is still mostly hydrogen, starts to expand.
