Answer:
Na₂SO₄
Explanation:
Assume that you have 100 g of the compound.
Then you have 32.37 g Na, 22.57 g S, and 45.05 g O.
1. Calculate the moles of each element.
Moles of Na = 32.37 × 1/22.99 = 1.408 mol Na
Moles of S = 22.57 × 1/32.06 = 0.7040 mol S
Moles of O = 45.05 × 1/16.00 = 2.816 mol O
2. Calculate the <em>molar ratio</em>s.
Divide all values by the smallest number.
Na: 1.408/0.7040 = 2.000
S: 0.7040/0.7040 = 1
O: 2.816/0.7040 = 4.000
3. Determine the empirical formula
Round off all numbers to the closest integer.
Na: 2
S: 1
O: 4
The empirical formula is Na₂SO₄.
Could be from liquid (most common refrigerant) to gas phase.
Answer:

Explanation:
they are highest cloud type and are made of ice crystals
a. double replacement
b. AB + CD ⇒ AD +CB
c and d
H₃PO₄ : Phosphoric acid
KOH : Potassium hydroxide
K₃PO₄ : Tripotassium phosphate
H₂O : water
<h3>Further explanation</h3>
Given
Reaction
H₃PO₄ + 3 KOH → K₃PO₄ + 3 H₂O
Required
Type of reaction
General equation
Name of reactants and product
Solution
Double replacement reaction : Cations and anions of different compounds switch places
It can also be said as <em>a neutralization reaction</em> because it produces water(reaction between an acid and a base)
AB + CD ⇒ AD +CB
