To see if an equation is balanced, make sure that each side of the reaction has an equal number of the types of atoms. The one that has a mismatch is A
Atoms, because molecules are a group of two or more atoms stuck together :)
Answer:
A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets. The atoms consist of matter that has a nucleus in the centre. one mole of water contains 6.02 x 1023 MOLECULES of water But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.Feb 12, 2003
Explanation:
A drought is a period of drier-than-normal conditions that results in water-related problems.<span> When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases.</span>
Answer:
60g
Explanation:
Moles = mass / mollar mass
Mass = Moles x mollar mass
Mass = 2.50 x 24
Mass = 60g
