First you find the atomic mass of CH2
they give you the mass so it is
12.01+ (2 x 1.008) (because there’s 2 H)
= 14.026
divide 70.13/14.026= 5
now you multiply the coefficient by 5 so
CH2 becomes C5H10
hope that helped

Which of the following is true for an excess reactant?
kupik [55]

Answer:

C) It is the reactant that is left over after the reaction stops.

Explanation:

The excess reactant is the reactant that is left over after the reaction stops. The extent of the reaction is not determined by this reactant.

A limiting reactant is a reactant that is in short supply within a given reaction.

Such reactants determines the extent of chemical reaction.

  • Limiting reactants are used up in a chemical reaction.
  • The excess reactants remains unchanged after the reaction.

A) What mass in grams of H20 is needed to react completely with 40.0 g of
Step2247 [10]

Answer:

m_{H_2O}=9.24gH_2O

Explanation:

Hello there!

In this case, since there is a 2:2 mole ratio between sodium peroxide and water according to the given reaction, it is possible to apply the following stoichiometric setup for the calculation of the required mass of water:

m_{H_2O}=40.0gNa_O_2*\frac{1molNa_O_2}{78gNa_O_2}*\frac{2molH_2O}{2molNa_O_2}  *\frac{18.02gH_2O}{1molH_2O} \\\\m_{H_2O}=9.24gH_2O

Best regards!

Lostsunrise [7]

Answer:

3.6 × 10²⁴ atoms of O

Explanation:

Let's consider the molecular formula of silver nitrate: AgNO₃.

We can establish the following relations:

  • 1 mol of AgNO₃ has 6.02 × 10²³ molecules of AgNO₃ (Avogadro's number).
  • 1 molecule of AgNO₃ has 3 atoms of oxygen.

The atoms of oxygen in 2.0 moles of silver nitrate are:

2.0molAgNO_{3}.\frac{6.02\times10^{23}moleculeAgNO_{3}  }{1molAgNO_{3}} .\frac{3atomO}{1moleculeAgNO_{3}} =3.6\times10^{24}atomO

What is the mole fraction of cation in 1M of aluminium sulphate​
Svetllana [295]

The mole fraction of cation (Al)=0.4

<h3>Further explanation</h3>

Given

1 M of Aluminium sulphate​

Required

The mole fraction of cation

Solution

Ionization of the Aluminum sulfate solution( assume 1 L solution ) :

mol Al₂(SO₄)₃ = M x V = 1 M x 1 L = 1 mol

Al₂(SO₄)₃⇒2Al³⁺ + 3SO₄²⁻

1 mol          2 mol   3 mol

From this equation, total mol in solution = 2+3 = 5 moles

Mol fraction Al(as a cation) :

= 2/5=0.4
