What do you notice is different about the arrangement of the H 2 O molecules in solid form compared to the arrangement of molecu
Nonamiya [84]

Answer:

when the water is frozen, the molecules are tight and bunched together because its a solid. Although that the molecules seem to be tight, it does not meant that the molecules are not moving. The molecules in H 2 O solid form makes them move fast as in vibration. If the H 2 O was in liquid form, the molecules would be spread out and there would be plenty of room to move. But if the H 2 O is a gas, the molecules are even more loose that the liquid and they do whatever they choose to.

7. Which statement is true about particles in ice and in boiling water?
IceJOKER [234]

Answer:

A. particles are the same.

Explanation:

Hello, since we are talking about the water, the molecules are quite equal.

Nonetheless,  if you want to know it (because this is not in the answers), the particles move faster in the boiling water than in the ice, considering that in the boiling water there is a larger energy content, which allows the molecules to move faster (they "have" more energy). In addition, The molecules are closer in the ice because that is the only way for them to solidify (get together).

Best regards!

How many grams of iron metal do you expect to be produced when 245 grams of an 80.5 percent by mass iron (II) nitrate solution r
NNADVOKAT [17]
2Al + 3Fe(NO₃)₂ = 3Fe + 2Al(NO₃)₃

m=245 g
w=0.805 (80.5%)
M{Fe(NO₃)₂}=179.857 g/mol
M(Fe)=55.847 g/mol

1. the mass of salt in solution is:
m{Fe(NO₃)₂}=mw

2. the proportion follows from the equation of reaction:
m(Fe)/3M(Fe)=m{Fe(NO₃)₂}/3M{Fe(NO₃)₂}

m(Fe)=M(Fe)m{Fe(NO₃)₂}/M{Fe(NO₃)₂}

m(Fe)=M(Fe)mw/M{Fe(NO₃)₂}

m(Fe)=55.847*245*0.805/179.857= 61.24 g
