+2, because the element has more protons than electrons now
Answer:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... As a result, the particles take up more volume.
Answer: 160 g Fe2O3
Explanation: solution attached.
First convert molecules to moles using Avogadro's number then convert to mass using the relationship between moles and molar mass of Fe2O3
Option 4 is right option regarding incorrect association.
A nucleotide is a monomer made of sugar, base and phosphate group whereas nucleic acid is a polymer of nucleotide. Thus, this association is correct.
Amino acid is a monomer such as glycine, alanine whereas polypeptide made from association of number of amino acid by creating a peptide linkage to produce a polypeptide.
Monosaccharide is a monomer such as glucose, fructose which associates together to produce polysaccharide such as cellulose made from glucose.
nucleic acid is a polymer of nucleotide whereas polypeptide made from association of number of amino acid by creating a peptide linkage to produce a polypeptide.
Thus, option 4 is right option having incorrect association.
