Answer:
D They have the same properties.
Explanation:
The same no. of isotopes doesnot describes because isotopes have same symbol but didderent atomic mass.
Answer:
The correct answer is: <em>There must be potential energy in the bonds due to its particles position.</em>
Explanation:
Potential energy is a kind of energy which is stored in an object due to its position or configuration. For example, if there is a ball in the fifth floor of a building, it has a determined potential energy which is converted to kinetic energy when the ball fall down. The same is in the case of the chemical bonds: the particles or atoms have potential energy related to their relative positions in the system. In fact, chemical energy is considered a form of potential energy (stored in chemical bonds).
Answer:
I think it's A
Explanation:
H202 is hydrogen peroxide
H20 is water
The three particles found in an atom are the protons, neutrons and electrons. Protons have a positive charge. Electrons have negative charge. Lastly, neutrons have no net electrical charge. Protons and neutrons are much heavier than electrons and are located in the center of the atom.
Answer:
1.70 mol of ethanol is needed
Explanation:
First, we have to write the balanced equation for reaction of ethanol with oxygen to produce acetic acid and water
Balanced reaction:

According to balanced equation, 1 mol of ethanol produces 1 mol of 
So, moles of ethanol needed to produce 1.70 mol of water = 1.70 mol
