The result when the OH- ions go as additional acid is added is that t<span>hey remain in solution but change concentration. </span>This is because when you add more acid to hydroxide, it will change its concentration due to the acidity added.
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.

The equation can be written in terms of ions as:

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 ions which are present on both the sides of the equation are potassium and nitrate ions and hence are not involved in net ionic equation.
Hence, the net ionic equation is :

Answer:
Empirical formula is CH₃.
Explanation:
Given data:
Mass of carbon = 120 g
Mass of hydrogen = 30.3 g
Empirical formula = ?
Solution:
Number of gram atoms of C = 120 g / 12 g/mol = 10
Number of gram atoms of H = 30.3 g / 1.008 g/mol = 30.06
Atomic ratio:
C : H
10/10 : 30.06/10
1 : 3.06
C : H = 1 : 3
Empirical formula is CH₃.
Collagen in the human body connects and supports bodily tissue such as skin, bones, muscles and cartilage. It supports the internal organs and can even be found in teeth! Collagen's main function is to sustain tendons, skin, and cartilage and provide firmness and elasticity to those structures.
Answer:
Explanation:
%mass of glucose =( mass of gucose /mass of solution )x100%
= 163 / (755+ 163 )
= 17.76 %
