Answer : The correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
Explanation :
The general trend of atomic number and atomic mass in the periodic table is,
Both atomic number and atomic mass increase from left to right and decreases from right to left in the periodic table due to the addition of the number of neutrons and the number of protons in the nucleus.
Hence, the correct option is, (C) Both the atomic mass and the atomic number increase from left to right.
Answer:
1.75M
Explanation:
The problem deals with finding the molarity of the given compound.
The compound is:
Na₂SO₄.10H₂O
Mass of the compound = 10.5kg = 10500g
Volume of the compound = 18.6L
Molarity is the number of moles of solute in a solution;
Molarity = 
Number of moles = 
Molar mass of Na₂SO₄.10H₂O = 2(23) + 32 + 4(16) + 10[2(1) + 16]
= 322g/mol
Now;
Number of moles = 
= 32.6mole
So;
Molarity = 
= 1.75M
Answer:
A spectator ion is an ion that does not participate in a chemical reaction and is found in a solution before and after a reaction.
Hope this helped :)
Answer:
The rooe of rainforests in the water cycle is to add water to the atmosphere through the process of transportation(which in plants release water from their leaves during photosynthesis). When forests are cut down, less moisture goes into the atmosphere and rainfall declines, sometimes leading to drought
B) proton
electrons are in a cloud around it, ions are elements with a charge, idk what a free radical is but ik that protons and neutrons are inside the nucleas
