Answer:

The last answer would be correct because if you have ever done it before you would know that rubbing your feet (just like the rubbing of ice crystals) on the carpet will create the energy you need, then once you touch the metal it creates that spark!

Explanation:

hoped that helped-I would be thankful for brainliest ;)

6. The reaction of quicklime, CaO, with water produces slaked lime, Ca(OH)2, which is widely used in the construction industry t

vlabodo [156]

Answer:

1) Enthalpy of reaction per gram of quick lime or calcium oxide is -6.25 kJ/g.

2) $4.730\times 10^6$ kilo Joules of energy is produced when 1 Tonn of slaked lime is produced.

Explanation:

$CaO(s) + H_2O(l)\rightarrow Ca(OH)_2(s),\Delta H=-350 kJ/mol$

Enthalpy of reaction = ΔH = -350 kJ/mol

1 mole of calcium oxide = 56 g/mol

1 ) Enthalpy of reaction per gram of quick lime or calcium oxide:

$\frac{\Delta H}{56 g/mol}=\frac{-350 kJ/mol}{56 g/mol}=-6.25 kJ/g$

2) Mass of slake lime = 1 Tonn = 1,000,000 g

Moles of slaked lime = $\frac{1,000,000}{74 g/mol}=13,513.51 mol$

According to reaction, on formation of 1 mol of slaked lime 350 kilo Joules of energy is produced.

Then energy produced when 13,513.51 moles of slaked lime is produced:

$350 kJ\times 13,513.51 =4.730\times 10^6 kJ$

$4.730\times 10^6$ kilo Joules of energy is produced when 1 Tonn of slaked lime is produced.

What might two Group 16 non metals likely form?

just olya [345]

When the compound is composed of two non-metals, the the bond that joins them together is called covlent bond. Otherwise, when the compound is composed of a metal and a non-metal then the bond existing between them is called ionic bond. Answer then to this problem is A. covalent bond

Sulfuric acid, H2SO4, can be neutralized by sodium hydroxide, NaOH. The unbalanced equation is: H2SO4(aq) + NaOH(aq) → Na2SO4(aq

evablogger [386]

Answer: Sulfuric acid, H2SO4, can be neutralized by sodium hydroxide, NaOH. The unbalanced equation is:
H2SO4(aq) + NaOH(aq) → Na2SO4(aq) + H2O(l)
A student who was asked to balance the reaction wrote the following:
H2SO4(aq) + Na2OH(aq) →Na2SO4(aq) + H3O(l)
Is this correct? Explain why or why not using what you know about the law of conservation of mass and chemical changes. If necessary, provide the correct balanced equation.
Explanation: The mass of the reactants must equal that of the products. This is because the masses of the products arise from the reactants and no mass is either created or destroyed. The total mass of the reactant must equal that of the product side and vice versa.
The student made an error of protonating the water molecule to H3O+ without a corresponding balance on the reactant side. In this case, it is wrong and ceases to be an equation. The product side masses don't equal the reactant side.
Balancing a chemical equation is done by first writing the correct chemical symbol. The moles and masses of each compound are cross-checked that they are equal on both sides of the equation.
