In general the inter- molecular attraction between particles of gases is much more smaller than those found in the particles of liquids. Because of this, the particles of gases are usually far apart from one another while the particles of liquid are closer together compares to that of gases.
Sn(s) + 2 HF(aq) ----> SnF2(s) + H2(g)
M HF = 20 g/mol
M SnF2 = 157 g/mol
40 g (HF) -----> 157 g (SnF2)
30 g (HF) -----> x g (SnF2)
x = 30 g × 157 g / 40 g = 117,75g
Answer: 117,75 g

Explanation:
Formula
density = mass / volume
Givens
mass = 26.94
volume = 2.568
Solution
density = 26.94 / 2.568
density = 10.49 grams / cc^3
Answer
This is very likely silver.
The givens in the table except for the first 2 are wrong.
silver is as above
copper is a bit over 8.
Answer :
Explanation :
The aluminium and fluorine react to give ionic compound aluminium fluoride.
Aluminium has 1 valence electrons in their shell and fluorine has 7 valence electrons in their shell.
For the complete octet, both aluminium and fluorine exchange valence electrons to form an ionic compound.
The aluminium donates its three valence electrons to three fluorine atoms and they form one and three ions.
