Why are metal containers not used for storing acids​

I’m pretty sure they are, but it depends on which acids. Some acids have a really high or low ph that can burn through items, like our stomach acid. Instead, something with a high melting point would be used.

<h2>Answer:</h2>

Metal containers are not used for storing acid because most of the time acid reacts with almost every metal and produces salts or <em><u>oxides</u></em> which alters the acid characteristics making it <em>useless.</em><em>.</em><em>.</em><em>.</em>

What is the total mass of kno3 that must be dissolved in 50. Grams of h2o at 60.°c to make a saturated solution?
Trava [24]

Answer:

55 g

Explanation:

First, we have to look for the solubility of KNO₃ at 60°C, considering that the solubility is the maximum amount of solute that can be dissolved in 100 grams of solvent, that is, the concentration of a saturated solution.

The solubility of KNO₃ at 60°C is 110.0 g of KNO₃ per 100 g of water. The mass of KNO₃ that must be dissolved in 50 g of water to make a saturated solution is:

50 g H₂O × (110.0 g KNO₃/100 g H₂O) = 55 g KNO₃

Sheena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation?
Ksivusya [100]

Answer:

The volume of a ball that is 24 cm across is :

d). v = four-thirds pi 12 cubed

Explanation :

Ball is a sphere and volume of sphere is given by :

\frac{4}{3}\Pi r^{3}

r = radius of ball

r =\frac{24}{2}

r = 12 cm

Volume is :

\frac{4}{3}\Pi \times 12^{3}

What is the theoretical yield of aluminum that can be produced by the reaction of 60.0 g of aluminum oxide with 30.0 g of carbon
Varvara68 [4.7K]

Answer: 31.8 g

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} Al_2O_3=\frac{60.0g}{102g/mol}=0.59moles

\text{Moles of} C=\frac{30.0g}{12g/mol}=2.5moles

Al_2O_3+3C\rightarrow 2Al+3CO  

According to stoichiometry :

1 mole of Al_2O_3 require 3 moles of C

Thus 0.59 moles of Al_2O_3 will require=\frac{3}{1}\times 0.59=1.77moles  of C

Thus Al_2O_3 is the limiting reagent as it limits the formation of product and C is the excess reagent as it is present in more amount than required.

As 1 mole of Al_2O_3 give = 2 moles of Al

Thus 0.59 moles of Al_2O_3 give =\frac{2}{1}\times 0.59=1.18moles  of Al

Mass of Al=moles\times {\text {Molar mass}}=1.18moles\times 27g/mol=31.8g

Thus 31.8 g of Al will be produced from the given masses of both reactants.
