How many grams of Ca(I03)2, is produced if the yield is 100%?

Answer:

Write the balanced equation 2C2 H6 + 702 ==>4C02 + 6H2.... balanced equation ethane....oxygen....carbon dioxide...water

Answer:

Covalent bond.

Explanation:

It involves sharing electrons equally between both molecules.

Answer:

2 Reactants

Explanation:

its the iron and oxygen

Answer:

Inorganic impurities present in the bulk of a liquid such as KCl tend to increase the surface tension of water.

Explanation:

As potassium chloride (KCl) dissolves in water, the ions are hydrated. ... When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them.

Answer:

[tex]0.55284g/mL[/tex]

Explanation:

Hello there!

In this case, given the by-mass percent of ethanol:

[tex]\frac{70gEt}{100gSol}[/tex]

It is possible to compute the density by using its molar mass to find the grams in one liter of solution:

[tex]12\frac{molEt}{1L}*\frac{46.07 gEt}{1molEt}=552.85g/L[/tex]

However, by taking the g/mL we obtain:

[tex]552.84\frac{g}{L} *\frac{1L}{1000mL}=0.55284g/mL[/tex]

Which is the density of the solution.

Answer:

The total mass of glucose and oxygen is equal to the total mass of carbon dioxide and water.

Explanation:

:)

Answer:

0.559 L

Explanation:

Step 1: Given data

Step 2: Calculate the volume of solution (V)

The molarity is equal to the moles of solute divided by the liters of solution.

M = n/V

V = n/M

V = 0.405 mol/(0.724 mol/L) = 0.559 L

The volume in Litres of a 0.724 M Nal solution that contains 0.405 mol of Nal is 0.56L.

Answer:

0.5 mol dm⁻³

Explanation:

The reaction that takes place is:

First we convert the given volumes to dm³(1000cm³ = 1 dm³):

Now we calculate how many NaOH moles reacted, using the given volume and concentration:

Then we convert NaOH moles into H₂SO₄ moles, using the stoichiometric coefficients:

Finally we calculate the concentration of H₂SO₄:

Answer:

42.61 g of NaOH.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2Na + 2H₂O —> 2NaOH + H₂

Next, we shall determine the mass of Na that reacted and the mass of NaOH produced from the balanced equation. This is illustrated below:

Molar mass of Na = 23 g/mol

Mass of Na from the balanced equation = 2 × 23 = 46 g

Molar mass of NaOH = 23 + 16 + 1

= 40 g/mol

Mass of NaOH from the balanced equation = 2 × 40 = 80 g

SUMMARY:

From the balanced equation above,

46 g of Na reacted to produce 80 g of NaOH.

Finally, we shall determine the mass of NaOH produced by the reaction of 24.50 g of Na. This can be obtained as follow:

From the balanced equation above,

46 g of Na reacted to produce 80 g of NaOH.

Therefore, 24.50 g of Na will react to produce = (24.50 × 80)/46 = 42.61 g of NaOH.

Thus, 42.61 g of NaOH were obtained from the reaction.
