What is the mass of aluminum oxide (101.96 g/mol) produced from 1.74 g of manganese(iv) oxide (86.94 g/mol)?

Chemistry

NemiM [27]2 years ago

the mass of aluminum oxide (101.96 g/mol) produced from 1.74 g of manganese(iv) oxide (86.94 g/mol) is 1.36g

The reaction is 3 MnO2 + 4 Al ------ 2Al2o3+ Mn

3 mole of manganese oxide give 2 moles of aluminum oxide so by the reaction n( MnO2)/3 =n(al203)2

the formula is n= mass/M so, now substituting values

m (Al2O3)= m(MnO2) X 2 X M (Al2O3) / M(MnO2 X3

so, by substituting values, 2 X101.96 X1.74g / 3 X 86.94 =1.36g

so mass of aluminum oxide obtained = 1.36g

What would you need to do to calculate the molarity of 10g of NaCl in 2kg of water?
Artist 52 [7]

Answer:

B) we will convert the 10 g of NaCl into moles.

Explanation:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

we will convert the 10 g of NaCl into moles.

Number of moles of NaCl:

Number of moles = mass/molar mass

Number of moles = 10 g/ 58.44 gmol

Number of moles = 0.17 mol

1 Kg = 1 L

Molarity = 0.17 mol / 2 L

Molarity = 0.085 mol/L

Molarity = 0.085 M

Which of the following is an aldehyde?
balu736 [363]

Answer:  CH_3CH_2CH_2CHO has aldehyde functional group.

Explanation:

Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

A.  CH_3CH_2CH_2COCH_3 has ketone C=O functional group .

B.  CH_3CH_2CH_2COOH has carboxylic acid COOH functional group .

C.  CH_3CH_2CH_2CHO has  aldehyde H-C=O functional group .

D. CH_3CH_2CH_2COOCH_3 has ester RO-C=O functional group .

Thus CH_3CH_2CH_2CHO has aldehyde (CHO) group.
