Maybe the dessert, because it's dry
Answer:
the two major sources of energy for the rock cycle are also shown; the sun provides energy for surface processes such as weathering, erosion, and transport, and the Earth's internal heat provides energy for processes like subduction, melting, and metamorphism.
Pt195 having 78 atomic number is the daughter nucleus produced when Au195 undergoes electron capture.
An unstable isotopes can undergoes radioactive decay to form a more stable isotopes . Initial isotopes is called parent nuclide and the resultant isotopes from radioactive decay is called the daughter nuclide There are several radioactive decay like alpha decay , beta decay , gamma decay , electron capture etc .
In electron capture , the atom have only one less which is daughter isotopes than electron than atomic number of parent isotopes.

Answer:
Isotopes of bromine have same chemical properties because they have same number of electrons.
Isotopes have only different number of mass that does not affect it's chemical properties too much.
Answer:
3.86x10^24 molecules
Explanation:
From the question given, the following data were obtained:
Volume of ice = 0.5cup
1 cup = 240mL
0.5cup = 0.5 x 240 = 120mL
Density of ice = 0.9167 g/mL
molar mass of water = 18.015g/mol
First let us calculate the mass of ice. This is illustrated below:
Density = Mass /volume
Mass = Density x volume
Mass = 0.9167 x 120
Mass of ice = 110.004g = Mass of water
From Avogadro's hypothesis, we understood that 1mole of any substance contains 6.02x10^23 molecules. This means that 1mole of water will also contain 6.02x10^23 molecules.
1mole of water = 18.015g
If 1 mole (18.015g) contains 6.02x10^23 molecules,
Therefore, 110.004g of water will contain = (110.004x6.02x10^23)/18.015 = 3.86x10^24 molecules
