Thus 3 moles of ions are released when samples dissolves definitely in water.
Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms.
<h3>How many ions are in a mole?</h3>
One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The variety 6.022 × 10²³ is acknowledged as Avogadro's number or Avogadro's constant.
<h3>How plenty is a mole of water?</h3>
18.0146 grams
The atomic mass of hydrogen is 1.0078 and the atomic mass of oxygen is 15.999, so the mass of a mole of water is two x 1.0078 + 15.999. Therefore, a mole of water, or 6.022 x 1023 molecules, weighs 18.0146 grams.

Answer:
The answer is B
Explanation:
Because conduction of heat or electricity occurs through a medium(for eg. The heat from a fire going through a metal pot . So in this example the pot is the medium of conduction).
And in this question the medium of heat conduction is the ground, with the heat moving in an upward motion .
The sun grows plants, animals eat plants, we eat animals giving us energy
Answer:
Ammonia is a compound.
Explanation:
A compound is composed of two or more separate elements. Ammonia is NH3, which happens to be two different elements.
Combustion:
The saturated hydrocarbons are relatively inert except at high temperatures. Combustion is one of the more important chemical reactions of the alkanes.
Alkanes have the general formula of CnH2n+2. For example, an alkane with 6 carbon atoms (n = 6) would have a formula of C6H2·6+2 or C6H14. Structurally C6H14 would be shown as:
