Answer:
Climate is long time intervals and weather is short time intervals
Explanation:
Balanced chemical reaction:
PbO₂<span>(s) + Sn(s)+ 4H</span>⁺(aq) → Pb²⁺(aq) + Sn²⁺(aq) + 2H₂O<span>(l).
Oxidation half-reaction: Sn </span>→ Sn²⁺ + 2e⁻.<span>
Reduction half-reaction: PbO</span>₂ + 4H⁺ + 2e⁻ → Pb²⁺ + 2H₂O.
Net reaction: Sn + PbO₂ + 4H⁺ + 2e⁻ → Sn²⁺ + 2e⁻ + Pb²⁺ + 2H₂O.
Oxidation is increase of oxidation number, reduction is decrease of oxidation number.
The single combination of pressure and temperature at which liquid water, solid ice, and water vapor can coexist in a stable equilibrium occurs at approximately 273.1575 K (0.0075 °C; 32.0135 °F) and a partial vapor pressure of 611.657 pascals (6.11657 mbar; 0.00603659 atm).[4][5] At that point, it is possible to change all of the substance to ice, water, or vapor by making arbitrarily small changes in pressure and temperature. And the temperature is called Triple point
Answer:
Atomic #: 82
Mass #: 206
Charge: 4+
# of protons: 82
# of electrons: 78
# of neutrons: 124
Explanation:
Atomic #: look at the bottom left #, it's always the atomic #.
Mass #: look at the top left # it's always the mass #.
Charge: they give you the charge which is shown on the upper right of the element.
# of protons: is the atomic #
# of electrons: also the atomic # minus 4 bc the charge is a positive 4, indicating that some electrons 'left'.
# of neutrons: 206 (mass # is protons + neutrons) minus 82 (atomic#) which is 124.
