Answer:
5.35m H2O2 x 34.02g/1m H2O2 = 182g H2O2
Explanation:
B) Tellurium is a metalloid. Metalloids in some classifications are also or alternatively called “semi-metals.”
A. Chemical energy can be in many forms including in the chemicals found in food
Answer:
Water (H2O) is polar due to the bent shape of the molecule. The shape means most of the negative charge from the oxygen is one one side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding.
Hope this helps!
Answer:
weak acid
Explanation:
pH scale is from 0 to 14
pH =7 is for water which is neutral. it is neither acidic or basic as the hydrogen ion concentration is equal to hydroxyl ion concentration.
Lesser the pH value than 7 greater the acidic nature. And greater the pH value than 7 more the basic nature.
Given pH=3-7 So the indicated interval represents weakly acidic.
