Explanation:
The unbalanced nuclear equation is

Let's write the question mark as a nuclear symbol.

The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.
Then
98 = 0 + A, so A = 98 - 0 = 98, and
38 = -1 + Z, so Z = 38 + 1 = 39
Then, your nuclear equation becomes

Element 39 is yttrium, so the balanced nuclear equation is

Sucrose Disaccharide
Sucrose, also called table sugar with molecular formulae C12H22O11 is a disaccharide composed of two monosaccharides ( 50%glucose + 50% fructose.).
Lactose Disaccharide
Lactose with molecular formula C12H22O11, found in milk is a disaccharide composed of two monosaccharides (galactose and glucose).
Fructose Monosaccharide
Fructose with molecular formulae C6H12O6 is a natural sugar mostly found in fruits.
Starch Polysaccharide
Starch ,a complex carbohydrate with molecular formula (C6H10O5)n, is a Polysaccharide containing many units of glucose joined together by 1,4 linkages. Sources of starch can be found in the parts of plants( roots, tubers etc).
Glucose monosaccharides
Glucose, is a simple sugar (monosaccharides) with the molecular formula C6H12O6. It is found in parts of plants as well as in humans and known as blood sugar because of its location in the bloodstream.
Answer:
Some materials let electricity pass through them easily. These materials are known as electrical conductors. Many metals, such as copper, iron and steel, are good electrical conductors.
