When electricity flows through water, the water molecules split into molecules of hydrogen and oxygen gas. How many oxygen (O2)

molecules are produced from the splitting of two molecules of water (H2O) if the balanced equation for the reaction is as follows?

Answer: The number of oxygen molecules produced are 1.

<u>Explanation:</u>

Water is formed by the combination of hydrogen and oxygen atoms.

Water splits into 2 types of molecules when electricity is applied.

The balanced chemical equation for the splitting of water into its molecules follows:

2H_2O\rightarrow 2H_2+O_2

By Stoichiometry of the reaction:

2 moles of water splits to form 2 moles of hydrogen molecule and 1 mole of oxygen molecule.

Or,

2 molecules of water splits to form 2 molecules of hydrogen and 1 molecule of oxygen.

Hence, the number of oxygen molecules produced are 1.

Four research teams measured the length of a rare whale, and what each team wrote in its team notebook is shown in the table bel
vovikov84 [41]

Answer:

Explanation:

Precision relates to instruments of measurement or scale . A scale measuring upto cm is less precise than an instrument measuring upto mm .

Here the first measurement appears to have been taken with an instrument measuring up to metre and the second measurement appears to have been taken with an instrument measuring up to decimeter . So second measurement is most precise .

Third measurement is closest to the actual measurement that is 45.0 m , so it is most accurate measurement .
