Write formula for these compounds: a. Sodium iodide b. Tin (II) chloride c. Potassium Sulfide d. Calcium iodide
Answers
All these compounds are ionic compounds and the formula of the compounds are: Tin(II) chloride - SnCl₂, potassium sulphide- K₂S, calcium chloride - CaCl₂.
What is chemical formula?
The chemical formula of a compound make them easy to identify the elements of composition. The formula of a compound s given with the chemical symbols of elements.
The subscripts of atoms is the number of that elements in the compounds. For instance, tin(II) chloride is formed by losing two electrons from the metal tin -Sn to each two chlorine atoms and thus the formula is SnCl₂.
Potassium sulphide is an ionic compound formed by losing one electrons from potassium to the sulphur atom. Sulphur needs two electrons to attain octet thus it binds with two K atoms and the formula is K₂S.
Calcium chloride is formed by the ionic bonding between calcium and chlorine atom. Calcium has the valency of two thus, it donates two electrons each to each chlorine atoms and hence the formula is CaCl₂.

Answer;
New information changed the understanding of the atom’s structure.
Explanation;
- Mendeleev is know as the Father of the Modern Periodic Table. His table allowed scientists to predict the existence of elements that hadn't been discovered.
- Mendeleev saw that when the elements were arranged in order of increasing atomic mass, those that had similar properties occurred in a repeating pattern. He predicted that elements yet to be found would fill the gaps in his table.

The punnet square shows that all of the offspring are hererozygus. The dominant trait which is green will be shown over the recessive trait which is yellow.
100% of the offspring should have green pods.
Genotype
100% heterozygus (different) Gg
Phenotype

What is glucose ?
A basic sugar, glucose has the chemical formula C6H12O6. The most prevalent monosaccharide, a type of carbohydrate, is glucose.
The primary form of sugar in the blood, glucose serves as the body's cells' main source of energy. Glucose can be produced by the body from other chemicals, or it can be obtained from the meals we eat. The bloodstream carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.
The brain is the most energy-hungry organ in the body and uses half of the body's sugar energy due to its abundance of nerve cells, or neurons. Thinking, memory, and learning are all tightly correlated with blood glucose levels and how effectively the brain uses this substance.
Thus, a homopoloymer of glucose is corn starch.
