When it is tilted away from the Sun, it is winter in the northern hemisphere. In between we have autumn and spring. The day that the Earth's North Pole is tilted closest to the sun is called the summer solstice. This is the longest day (most daylight hours) of the year for people living in the northern hemisphere.

Water can be formed in the following reaction:
andreev551 [17]

Answer is: 10 moles of water will be produced.

Balanced chemical reaction of formation of water:

2H₂ + O₂ → 2H₂O.

n(H₂) = 10 mol; amount of hydrogen gas.

From balanced chemical reaction: n(H₂) : n(H₂O) = 2 : 2 (1 : 1).

n(H₂O) = n(H₂).

n(H₂O) = 10 mol; amount of water.

state the formula for potassium hydroxide and explain, in terms of charges, how you formed the formula
Ganezh [65]

Potassium oxide is an ionic compound. The potassium has a charge of <span>K+</span> and oxygen has a charge of <span>O<span>2−</span></span>. We need 2 potassium ions to balance one oxide ion making the formula <span><span>K2</span>O</span>.

Potassium hydroxide is an ionic compound. The potassium has a charge of <span>K+</span> and hydroxide has a charge of <span>OH−</span>. We need 1 potassium ion to balance one hydroxide ion making the formula KOH.

<span><span>K2</span>O+<span> H2</span>O→KOH</span>

To balance the equation we place a coefficient of 2 in front of the potassium hydroxide.

<span><span>K2</span>O+<span>H2</span>O→2KOH</span>

I hope this was helpful.
