Answer:
Explanation:
This is an example of a limiting reactant question, and is very common as a general chemistry problem.
We first see the balanced equation, that is:
2CuCl2+4KI→2CuI+4KCl+I2
We first need to find the limiting reactant
We see that 0.56 g of copper(II) chloride (CuCl2) reacts with 0.64 g of potassium iodide (KI) . So, let's convert those amounts into moles.
Copper(II) chloride has a molar mass of
134.45 g/mol . So in 0.56 g of copper(II) chloride, then there exist
0.56g134.45g/mol≈4.17⋅10−3 mol
Potassium iodide has a molar mass of
166 g/mol . So, in 0.64 g of potassium iodide, there exist
if it wrong i am sorry
There is no single chemical composition that characterizes all glass. Typical glass contains formers, flexes, and stabilizers. Formers make up the largest percentage of the mixture to be melted. And typical soda-lime-silica glass the former is silica (silicon dioxide) in the form of sand.
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.
