Answer:

2KOH + H2SO4 > K2SO4 + 2H2O

Explanation:

firstly the order speaks, you can't have something like OKOH so the other two is eliminated. Then check if the remaining reactions balance

Answer: Option b. 50 neutrons and 38 protons.

Explanation:

Atomic number = proton number = 38

Mass number = proton number + Neutron

Mass number = 88

Proton = 38

Neutron number =?

Neutron number = Mass number — proton number

Neutron number = 88 —38 = 50

How long would it take to produce enough aluminum to make a case (24 cans) of aluminum soft drink cans if each can used 3 g of a
kozerog [31]

Answer : It takes time to produce 3 g of aluminium is, 165 seconds.

Explanation :

As we are given that the mass of aluminium is, 3 grams. Now we have to calculate the total mass of aluminum.

Total mass of aluminum = 3g × 24 = 72 g

Now we have to calculate the moles of aluminum.

\text{Moles of Al}=\frac{\text{Mass of Al}}{\text{Molar mass of Al}}

Molar mass of Al = 27 g/mol

\text{Moles of Al}=\frac{72g}{27g/mol}=2.67mol

As, 1 mole of Al has 3 Faradays

So, 2.67 mole of Al has = 2.67\times 3=80.1 Faradays

and,

Charge = 80.1\text{ Faradays}\times \frac{96500\text{ coulombs}}{1\text{ Faradays}}=7.73\times 10^6\text{ coulombs}

Current = 5.00\times 10^4A\times \frac{93.9}{100}=46950A

Now we have to calculate the time.

Time=\frac{Charge}{Current}=\frac{7.73\times 10^6}{46950}=164.6s\aaprox 165s

Hence, it takes time to produce 3 g of aluminium is, 165 seconds.
