Answer:
sulphuric acid and ammonium hydroxide
Explanation:
They are different types of batteries. there are zinc carbon batteries, alkaline batteries, lithium carbon batteries, lead-acid batteries.
lithium is used for high performance devices such as smartphones, digital cameras and even electric cars.A variety of substances are used in lithium batteries, but a common combination is a lithium cobalt oxide cathode and a carbon anode
lead-acid batteries: This is the chemistry used in a typical car battery. The electrodes are usually made of lead dioxide and metallic lead, while the electrolyte is a sulfuric acid solution.
zinc carbon batteries; The anode is zinc, the cathode is manganese dioxide, and the electrolyte is ammonium chloride or zinc chloride.
alkaline batteries;The cathode is composed of a manganese dioxide mixture, while the anode is a zinc powder. It gets its name from the potassium hydroxide electrolyte, which is an alkaline substance.
The parent isotope percent will change from 100% to 50% to 25% to 12.5% and to 6.25%. So the sample go through four times of half-life. So the sample is 58*4=232 years old.
Answer:
they can change how we think,move and even how we feel about things!

Colloids have small non-dissolved particles that flow around in the mixture. These particles do not settle over time. When a light is shined on colloids the scattering characteristic of the Tyndall effect are visable.</span>
