What happens to Earth when it is farthest from the sun?

Nata [24]

Answer:

Explanation:

The Earth is closest to the Sun, or at the perihelion, about 2 weeks after the December Solstice, when it is winter in the Northern Hemisphere. Conversely, the Earth is farthest away from the Sun, at the aphelion point, 2 weeks after the June Solstice, when the Northern Hemisphere is enjoying warm summer months.

Therefore, most countries might have two or four seasons.

Determine whether each of the following is a strong acid, a weak acid, or a species with negligible acidity.Drag the appropriate

sp2606 [1]

Answer:

CH₃NH₃⁺ is a weak acid.

HPO₄²⁻ has a negligible acidity.

CH₄ has a negligible acidity.

HNO₂ is a weak acid.

Explanation:

There are 7 strong acids: HCl, HBr, HI, HNO₃, H₂SO₄, HClO₃, HClO₄. The rest of the acids are weak.

CH₃NH₃⁺ is a weak acid, according to the following equation:

CH₃NH₃⁺ ⇄ CH₃NH₂ + H⁺

HPO₄²⁻ can act as an acid or as a base:

Acid reaction: HPO₄²⁻ ⇄ PO₄³⁻ + H⁺

Basic reaction: HPO₄² + H₂O ⇄ H₂PO₄⁻ + OH⁻

Given Kb > Ka, HPO₄²⁻ has a negligible acidity.

CH₄ cannot release nor accept H⁺ so it has a negligible acidity.

HNO₂ is a weak acid, according to the following reaction:

HNO₂ ⇄ H⁺ + NO₂⁻

In which reaction does the oxidation number of hydrogen change? In which reaction does the oxidation number of hydrogen change?

dedylja [7]

Answer: The correct answer is $2Na(s)+2H_2O(l)\rightarrow 2NaOH(aq.)+H_2(g)$

Explanation:

Oxidation number is defined as the number which is given to an atom when it looses or gains electron. When an atom looses electron, it attains a positive oxidation state. When an atom gains electron, it attains a negative oxidation state.

Oxidation state of the atoms in their elemental state is considered as 0. Hydrogen is present as gaseous state.

For the given chemical reactions:

Reaction 1: $2HClO_4(aq.)+CaCO_3(s)\rightarrow Ca(ClO_4)_2(aq.)+H_2O(l)+CO_2 (g)$
