12.25 g of aluminium nitrate Al(NO₃)₃ are needed to prepare the solution.

Explanation:

First we determine the number of moles of aluminium nitrate:

molar concentration = number of moles / volume (L)

number of moles = molar concentration × volume (L)

number of moles of aluminium nitrate = 0.230 × 0.250

number of moles of aluminium nitrate = 0.0575 moles

Then we calculate the mass of aluminium nitrate Al(NO₃)₃:

mass = number of moles × molecular weight

mass of aluminium nitrate = 0.0575 × 213

mass of aluminium nitrate = 12.25 g

a hydrogen-filled balloon was ignited and 1.60g of hydrogen reacted with 12.8g of oxygen. how many grams of water vapor were for
Anon25 [30]
2H2 + O2 ---> 2H2O

1 mole of H2 = 2g
1 mole of O2 = 32g
1 mole of H2O = 18g

according to the reaction:
2*2g H2---------------32g O2
1,6g H2----------------- x g O2
x = 12,8g O2

so reaction is stechiometric

32g O2---------------- 2*18g H2O
12,8g O2 -------------- x
x = 14,4g H2O

answer: 14,4g of water vapour

Which orbital is partially filled in the Zirconium (ZI) atom?
Nikolay [14]

Answer:

4d orbital.

Explanation:

Hello!

In this case, since zirconium's atomic number is 40, we fill in the electron configuration up to 40 as shown below:

1s^2,2s^2,2p^6, 3s^2,3p^6,4s^2,3d^{10},4p^6,5s^2,4d^2

Thus, the orbital 4d is partially filled.

Best regards!
