Answer:

<em>If you are given a chemical equation and specific amounts for each reactant in grams, you have to follow these steps, in order, to determine how much product can possilby be made:</em>

  • <u><em>1. Convert each reactant into moles of the product. </em></u>
  • <u><em>2. Determine which reactant is the limiting reactant. </em></u>
  • <u><em>3. Convert the moles of product, from the limiting reactant, to grams</em></u><u>.</u>

Justification:

The balanced chemical equation, through the coefficients, represents the proportions, in terms of mole ratios, in that each reactant chemically react with each other to form each product.

So, if you are given specific aomunts for each reactant in grams, you must start by converting each reactant amount into mole numbers, using the molar mass of each one.

Then, using the theoretical mole ratios (from the coefficients of the balanced chemical equation) you can determine how much of each product can be produced, in terms of moles, first starting with the complete consumption of one of the reactants, and then doing the same with each of the other reactants, one by one.

The reactant that yields the least amount of product is the limiting reactant, since it will be consumed completely once that amount of product is obtainded, while the other reactants will be in excess.

Now, that you have the number of moles that can be produced from the limiting reactant, you can convert it into grams of product, just using the molar mass of the same.

400. mg of an unknown protein are dissolved in enough solvent to make 5.00 mL of solution. The osmotic pressure of this solution
ch4aika [34]

<u>Answer:</u> The molecular weight of protein is 1.14\times 10^2g/mol

<u>Explanation:</u>

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

\pi=iMRT

or,

\pi=i\times \frac{m_{solute}\times 1000}{M_{solute}\times V_{solution}\text{ (in mL)}}}\times RT

where,

\pi = Osmotic pressure of the solution = 0.0861 atm

i = Van't hoff factor = 1 (for non-electrolytes)

m_{solute} = mass of protein = 400 mg = 0.4 g   (Conversion factor:  1 g = 1000 mg)

M_{solute} = molar mass of protein = ?

V_{solution} = Volume of solution = 5.00 mL

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of the solution = 25^oC=[25+273]K=298K

Putting values in above equation, we get:

0.0861atm=1\times \frac{0.4g\times 1000}{M\times 100}\times 0.0821\text{ L. atm }mol^{-1}K^{-1}\times 298K\\\\M=1136.62g/mol=1.14\times 10^2g/mol

Hence, the molecular weight of protein is 1.14\times 10^2g/mol

The Hall process for the production of aluminum involves the reaction of aluminum oxide with elemental carbon to give aluminum m
topjm [15]

Answer:

  • <u><em>1.7 × 10³ kg of ore.</em></u>

Explanation:

Call X the amount of aluminum ore mined to produce 1.0 × 10³ kg the aluminum metal.

Then, taking into account the yield of the reaction (82 % = 0.82) and the percent of aluminun in the ore (71% = 0.71), you can write the following equation:

  •  X         ×          71%                ×       82%     =     1.0 × 10³ kg

         ↑                      ↑                              ↑                     ↑

(mass of ore)    (% of Al in the ore)        (yield)        ( Al metal to obtain)

You must just simplify, solve and compute:

  • 0.71 × 0.82 × X = 1,000
  • X = 1,000 / (0.71 × 0.82) = 1,000 / 0.5822 = 1,717.6 Kg

Round to two significant figures; 1,700 kg = 1.7 × 10³ kg of ore ← answer.

Sodium chloride can be produced by the reaction of sodium metal with chlorine gas. Which is the limiting reactant if 6.70 moles
Alecsey [184]

Answer:

Chlorine gas.

Explanation:

Hello!

In this case, the undergoing chemical reaction is:

2Na+Cl_2\rightarrow 2NaCl

Thus, given the moles of reacting both sodium and chlorine, we compute the moles of sodium chloride yielded by each reactant by considering the 2:2 and 1:2 mole ratios:

n_{NaCl}^{by\ Na}=6.70molNa*\frac{2molNaCl}{2molNa}=6.70molNaCl \\\\n_{NaCl}^{by\ Cl_2}=3.20molCl_2*\frac{2molNaCl}{1molCl_2}=6.40molNaCl

Thus, since chlorine yields less moles of sodium chloride, we infer it is the limiting reactant.

Best regards!
