What kind of saccharide is this

Give at least one example from industry where a mixture must be separated in order to obtain the materials that are useful to so

deff fn [24]

The answer is; crude oil and iron ore

Iron ore is used to make steel (mainly Fe). However, the raw material contains a mixture of impurities such as pyrite and apatite that have to be removed. Crude oil also includes a mixture of different hydrocarbon and other impurities. Impurities such as water have to be removed and the hydrocarbon distilled to separate them.

30.00 ml of a h2so4 solution with an unknown concentration was titrated to a phenolphthalein endpoint with 44.45 ml of a 0.1489

kodGreya [7K]

The concentration of the H2SO4 solution should be 0.1101 M.

Calculation of the concentration:

Since

Volume of H2SO4 = 30.00 mL = 0.030 L

Volume of NaOH= 44.45 mL = 0.04445 L

Concentration of NaOH= 0.1489 M

Now

The balanced equation is

H2SO4 + 2NaOH → Na2SO4 + 2H2O

Now the concentration of the H2SO4 solution is

b*Ca*Va = a*Cb*Vb

here, b = the coefficient of NaOH = 2

Ca = ?

Va = the volume of H2SO4= 30.0 mL = 0.030 L

a = the coefficient of H2SO4 = 1

Cb = the concentration of NaOH = 0.1489 M

Vb = the volume of NaOH = 44.45 mL = 0.04445 L

Now

2*Ca*0.030 = 1* 0.1489* 0.04445

0.060 * Ca = 0.00661

Ca = 0.1101 M

Hence, The concentration of the H2SO4 solution is 0.1101 M.

Many metals react with acids to produce hydrogen gas. A certain reaction produces 32.6 L of hydrogen gas at STP. How many moles

morpeh [17]

Answer: 1.46moles

Explanation:

Applying PV= nRT

P= 1atm, V= 32.6L, R= 0.082, T = 273K

Substitute and simplify

1×32.6/(0.082×273)=n

n= 1.46moles
