Determine the ratio of moles of iron actually used to moles of new product actually formed. Does this molar ratio agree with the
KATRIN_1 [288]

The mole ratio of iron to copper is 1 : 1, thus, 1.31 g of iron is required to produce 1.5 g of copper.

<h3>What is the equation of the reaction between iron and copper(ii) sulfate?</h3>

The reaction between iron and copper(ii) sulfate is a redox displacement reactions in which copper is displaced from its salt by iron.

The equation of the reaction is given below:

CuSO_4 + Fe \rightarrow FeSO_4 + Cu

The mole ratio of both reactants and product is 1 : 1

  • moles = mass/molar mass

molar mass of copper sulfate = 160 g

molar mass of Cu = 64

molar mass of iron = 56 g

  • mole ratio of iron to copper = 1 : 1

moles of Cu in 1.5 g = 1.5/64 = 0.00234

mass of iron required = 0.00234 × 56 = 1.31 g of iron

Therefore, from the mole ratio of iron to copper, 1.31 g of iron is required to produce 1.5 g of copper.

How does an organic pH indicator works. (illustrate using chemical equations and
kap26 [50]

Answer:

A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually. Hence, a pH indicator is a chemical detector for hydronium ions (H3O+) or hydrogen ions (H+) in the Arrhenius model.A pH of 7 indicates a neutral solution like water. A pH less than 7 indicates an acidic solution and a pH greater than 7 indicates a basic solution. Ultimately, the pH value indicates how much H+ has dissociated from molecules within a solution. The lower the pH value, the higher concentration of H+ ions in the solution and the stronger the acid. Likewise, the higher the pH value, the lower the concentration of H+ ions in the solution and the weaker the acid.

Why might genetically identical twins have different phenotype
KIM [24]

Answer:

They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes?  Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.
