Mentos reacts to coca-cola because of the sugars and then they expand which causes the soda to explode out of the open container. this is a chemical reaction because it cause the sugars to expand which you can't see happen.
Answer;
A scalene
Explanation;
A triangle is a geometric figure with three sides and three angles that always add up to 180 degrees.
Based on properties triangles can be classified as equilateral, scalene, isosceles and right triangles.
Equilateral triangles has all the three sides and the angles equal, an isosceles triangle has two of its sides equal, and two angles that are known as the base angles equal. A scalene triangle has all the three angles and sides different from each other. A right triangle is a triangle in which one of the angle is right angle or is 90 degrees.
An isosceles triangle may be a right triangle, equilateral triangle, and also may be an acute triangle, however an isosceles triangle can never be a scalene triangle
Answer:
i think C the higher the frequency the lower the energy of light.
<u>Given information:</u>
A solution with a high H+ ion concentration
<u>To determine:</u>
The nature of pH of such a solution
<u>Explanation:</u>
pH is a measure of the H+ ion concentration in a given solution. Lower the pH higher will be the H+ concentration and the solution is termed acidic. In contrast, if the pH is higher the H+ concentration will be lower and the solution is basic.
Mathematically,
pH = -log[H+]
[H+] = 
pH = 2; [H+] = 10⁻²M
pH = 7; [H+] = 10⁻⁷M
pH = 13; [H+] = 10⁻¹³M
pH = 14; [H+] = 10⁻¹⁴M
Ans: (a)
Thus, the highest concentration of H+ ions is for a solution of pH = 2
