North magnets attract the opposite side in this case south would attract to north and vise versa if it was negative it would attract to positive and vise versa
Answer:
A proton has positive charge of 1, that is, equal but opposite to the charge of an electron. A neutron, like the name implies, is neutral with no net charge. The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons). need a pictur of the question
Explanation:
Potassium can be a component of the cream.
<h3>Why does potassium show white-purple flame when burned?</h3>
An element's presence can be determined using a flame test. The potassium in cream of tartar is what gives it its white-purple color.
Low ionization enthalpy elements allow the flame to display color. Due to low ionization enthalpy, when an element is heated, its valence electrons are quickly excited to higher orbits and emit light as they return to their original orbit. Salts of potassium emit a white-purple color when ignited. The cream of tartar's chemical formula is KC₄H₅O₆.

Answer:
2%
Explanation:
Original mass of water in glass = 10 ounces
amount that evaporates each day = 0.01 ounce
number of days = 20 days
Total amount that evaporated = 0.01 x 20 = 0.2 ounce
percentage of water that evaporated during this period = 0.2/10 x 100
= 2%
<em>Hence, the percentage of the original amount of water evaporated during this period is 2%</em>
Answer:
A Scientific Law
Explanation:
'When a substance goes through a chemical change the amount of mass and matter cannot be created nor destroyed.' This a statement of The Law of Conservation of Mass. This Scientific Law is simply titled as a law because every time experimented, the results are predictable and is natural occurrence.
