A student is told to use 20.0 grams of sodium chloride to make an aqueous solution that has a concentration of 10.0 grams of sod
Butoxors [25]

Volume of the solution = 20.0 g NaCl * \frac{1 L solution}{10.0 g NaCl}

= 2 L solution x \frac{1000 mL}{1 L} =2000 mL

Volume of solute = 7.5 mL

Volume of water (solvent) = 2000 mL - 7.5 mL = 1992.5 mL water

Given the equation:
Citrus2011 [14]

Answer: a)  Fe is the limiting reagent

b) 3.59 g

c) 11.6g

Explanation:

4Al_2O_3+9Fe\rightarrow 3Fe_3O_4+8Al  

To calculate the moles :

   

\text{Moles of} Al_2O_3=\frac{27.5g}{102g/mol}=0.27moles

\text{Moles of} Fe=\frac{8.4g}{56g/mol}=0.15moles

According to stoichiometry :

a) 9 moles of Fe  require= 4 moles of Al_2O_3

Thus 0.15 moles of Fe will require=\frac{4}{9}\times 0.15=0.067moles  of Al

Thus Fe is the limiting reagent as it limits the formation of product and Al is the excess reagent.

b) As 9 moles of Fe give = 8 moles of Al

Thus 0.15 moles of Fe give =\frac{8}{9}\times 0.15=0.133moles  of Al

Mass of Al=moles\times {\text {Molar mass}}=0.133moles\times 27g/mol=3.59g

c) As 9 moles of Fe give = 3 moles of Fe_3O_4

Thus 0.15 moles of Fe give =\frac{3}{9}\times 0.15=0.05moles  of Fe_3O_4

Mass of Fe_3O_4=moles\times {\text {Molar mass}}=0..05moles\times 231.5g/mol=11.6g

Elena L [17]

Answer:

Inhibition and tolerance.

Explanation:

Competitive inhibitors are characterized by being chemicals that are similar to the normal substrate. While non-competitive inhibitors are chemicals that bind to the enzyme and alter its shape. This renders the active site of the enzyme ineffective against the substrate. Tolerance makes a society that is fair and equitable.

MrMuchimi

Incomplete question. However, I answered from a general perspective.

<u>Explanation:</u>

Note, a flyer is a piece of advertising leaflet that is usually posted in public spaces, consisting of captivating as well as persuasive message designs. Although there are also digital flyers that can be distributed electronically.

Since in the case we imagine you are a cloth or plastic product manufacturer, your ideal flyer may contain such captions as;

→ with  [brand name]

YOUR BEAUTY IS AT ITS BEST!!!

→ LIVE THE MOMENT, EXPRESSION AT WORK!!!
