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.

Calculate the mass of 12.3 moles of MgSO4.​
Afina-wow [57]

Answer:

614 034 kg

Explanation:

n = m/Mm

m = n * Mm

Mm(MgSO4) = 1 * 24.3 * 1 * 32.1 * 4 * 16 = 49921.92

m = 12.3 * 49921.92

m = 614 034 kg
