Hey! 1) Convection [Warm water is less dense, so it rises.] 2) Conduction [The metal skewer is heated by the fire, and it is directly touching your hand. The metal skewer transfers heat to your hand through conduction.] 3) Conduction [The rock is directly touching you, so it transfers heat to you through conduction.] 4) Convection [Convection causes weather systems because hot air sinks and cold air sinks] 5) Convection [The hot air rises because it is less dense while the cold air sinks because it is denser.] ~Hope this helped~
Answer:
The answer to your question is: 63.5 u
Explanation:
Data Percent Molecular mass
63 Cu 69.2% 62.9296 u
65Cu 30.8% 64.9278 u
Average atomic mass = ?
Formula
Average atomic mass = (0.692 x 62.9296) + (0.308 x 64.9278)
= 43.55 + 19.99
= 63.5 u
Answer:
25
Explanation:
Isotopes of an element are the same element with different mass numbers but the same atomic number or the number of protons.
we know that in a balanced atom
Number of electrons = Number of protons = Atomic number
Atomic number (z) of manganese = 25
For Mn+5, the number of protons remains the same = 25
However, the number of electrons on Mn+5 = 21
A process called fission which generates heat to produce steam, which is used by a turbine generator to generate electricity.
