Answer: 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:
The complete ionic equation is:
The ions which are present on both the sides of the equation are lithium and chlorate ions. and hence are not involved in net ionic equation.
Thus the net ionic equation is:
Answer:
Atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

How can you maximize the use of useful materials that you have identified? empty bottles, fruits peeling,old news paper
The way to maximize the use of materials identified is by identifying the 3 R's of waste management which are Reduce, Recycle and reuse .
Explanation:
For example, when we check through the materialsempty bottles, fruits peeling,old news paper them can be Reduce, Recycle and reuse.
The plastic bottles can be recycled i.e converting the waste plastic materials into another useful materials like fabric, shoes, mats.
Fruits peeling can be reuse as composts for plants. These can be allow to be decompose which serve as plant compost to release nutrients for plants growth.
Old newspapers can be reduced by been sold to junks shop and some cash can be earned from it.
Answer:
The correct option is A.
Explanation:
A disaccharide refers to a sugar that is formed by the chemical bonding of two monosaccharides which are joined together via glycosidic bond.
A monosaccharide refers to any sugar that can not be reduced further to give a simpler sugar. When two monosaccharides residue come together they form a disaccharide ('Di' means two).
One good example of monosaccharide is glucose. When two glucose molecules or glucose and another monosaccharide join together they give rise to disaccharide such as surcose, lactose and maltose. The components of these disaccharides are given below:
1. Sucrose (Table sugar): Glucose + fructose.
2. Lactose (Milk sugar): Glucose + galactose.
3. Maltose: Glucose + glucose.
If my understanding is correct, what this saying is referring to is the conversion of energy from relatively useful forms to heat energy (which is relatively useless).
As you probably know, conservation of matter says that matter can be neither created nor destroyed. You may also be aware of the conservation of energy, which states that energy can be neither created nor destroyed, but only converted from one form to another. Whenever you have a chemical process, a complicated process called entropy is what drives the process (you don't need to know exactly what this is, but if you want to, you can look up the second law of thermodynamics). Part of that process often involves energy being converted to different forms--from useful forms (that can do work) to useless forms (that can't do work). Useful forms of energy are "useful" because they can do work, and in the process are converted to heat, which is not very useful for work, and generally cannot be converted back to useful forms. Matter, on the other hand, does not have "useful" and "useless" forms.
