a certain metal hydroxide, m(oh)2, contains 32.8% oxygen by mass. what is the identity of the metal m?

Leno4ka [110]

Total mass = x

It would be: x*32.38/100 = 32

x = 3200/32.38 = 97.56

Atomic mass of (OH)2 = 34

So, remaining mass = 97.56-34 = 63.56

which is approximately equal to mass of copper

So, we can say m is copper here, and formula of the compound would be Cu(OH)2

Predict the following product(s) of the following reaction? F2 + KCI →

slega [8]

Answer:

${ \rm{F _{2(g)} + 2KCl _{(aq)} → { \bold{2KF _{(g)} + Cl_{2(g)} }}}}$

Explanation:

» The prediction is 98% correct because single displacement reaction type is highly possible.

This is because Fluorine has is more electronegative than Chlorine in Potassium Chloride. So, it strongly displaces Chlorine from the solution hence forming Chlorine gas.

» The 2% of wrong prediction maybe because of wrong reactant measurements following mole concept chemistry.

If you are asked the observation,

Observation » A green yellowish gas is formed.

This gas is Chlorine gas (Cl2)
