My science text book said that it was either diamond or gold. Gold may not be right, but I am pretty sure diamond is.
Sorry if I got this wrong.
When compounds form, the atoms that bonded get a stable arrangement of electrons.
Compounds form because their atoms get a more stable arrangement than they had in the reactants.
A stable arrangement is a <em>complete octet</em> of eight electrons in the valence shell
.
Because the coldness in the ice cream and the suns gamma rays are hitting the ice cream and then it will start to melt. and that is why ice cream melts.
Answer:
12
Explanation:
You will need a chemical equation with masses and molar masses, so let’s gather all the information in one place.
: 258.21 18.02
KAl(SO₄)₂·xH₂O ⟶ KAl(SO₄)₂ + xH₂O
Mass/g: 4.74 2.16
Step 1. Calculate the mass of the KAl(SO₄)₂.
Mass = 4.74 g – 2.16 g = 2.58 g.
Step 2. Calculate the moles of each product.


Step 3. Calculate the molar ratio of the two products.

1 mol of KAl(SO₄)₂ combines with 12 mol H₂O, so x = 12.
