Which metal is more active than tin, but less active than zinc
VikaD [51]

Answer:

Iron (Fe)

Explanation:

The reactivity series shows a series of metals reactivity from lowest to highest. Based on the arrangement of metals in the reactivity series, iron is placed above tin and below zinc, this means that iron is more reactive than tin but less reactive than zinc. This means that iron would displace tin ions in a solution whereas zinc would displace iron ions in a solution.

The reactivity of metals is due to the stability of metals in their electron configurations as atoms and as ions.

What is the molality of a solution that contains 5 moles of solute in 100 kilograms of water?
slega [8]
<span>Answer:
molality = (moles of solute) / (kilogram of solvent)

moles of solute = (75.2 g AgClO4) / (mole mass AgClO4)
moles of solute = (75.2 g AgClO4) / (207.3206 g/mol)
moles of solute = 0.3627232 mol

molality = (0.3627232 mol) / (0.0752 Kg)
molality = 4.8234468 m or 4.82 m rounded to three significant figures </span>

alekssr [168]

Answer:

2 chlorine atoms.

Explanation:

H₂ + Cl₂ → 2HCl

The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.

If 2 molecules of Hydrogen and 2 molecules of Chlorine is present in the reactants, the same no. of atoms should also be present in the product.

∴ the no. of chlorine atoms in the product is 2.

A chemist measures the energy change Delta H during the following
Ann [662]

Answer: 1) endothernic

2) Yes absorbed

Explanation:

Decomposition is a chemical reaction in which one reactant gives two or more than two products. All decomposition reactions are endothermic reactions as energy is absorbed to break the bonds.

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and \Delta H for the reaction comes out to be positive.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and \Delta H for the reaction comes out to be negative.
