M(H2O) = 2*1.0 +16.0 = 18.0 g/mol
2.75 × 10⁻⁴ mol H2O * 18.0 g H2O/1 mol H2O = 4.95*10⁻³ g H2O
2[H⁺] + [O²⁻] → H₂O
Explanation:
Half reactions are usually composed of components of oxidation-reduction (redox) reaction where one element is losing electrons while another is gaining so they can come together into a compound. The half-reaction shows part of a reaction where the combining elements are charged and the product, from the redox, is neutral.
In this case, the H⁺ is carrying the positive charge because it is donating an electron to O²⁻, which is the reason the O²⁻ is carrying the negative charge. Note that we need 2 H⁺ for every one O²⁻. The O is being reduced while the H is being oxidized.

Answer:
It has direction and size.
Explanation:
All physical quantities are generally grouped into two;
i) Vector quantities
ii) Scalar quantities
Vector quantities are those quantities that has both magnitude (size) and direction.
Scalar quantities are those quantities that has magnitude (size) and no direction.
Velocity is a vector quantity because it has direction and size.
Answer:
3.87 x 10^24
Explanation:
Simply multiply the moles by avogadros number
6.42 moles of H2O x 6.022 x 10^23 molecules/1 mole of H2O = 3.87 x 10^24 molecules of H2O
