Answer:
197 + (35.5×3) = 303.5
Explanation:
relative formula mass is the sum of the relative atomic masses of the atoms in the formula ( AuCl3 )
Explanation:
This is due to a reduction in atmospheric pressure – pressure due to the weight of the overlying air column). Remember that the higher the altitude the lower the air density and subsequently the lower the air pressure.
Therefore when heating water at higher altitude the vapor pressure of the water at the surface overpowers the atmospheric pressure – which is slightly lower than at sea level – even before the water temperatures reach 100 degrees centigrade.

Answer:
C.) They have fewer electrons than protons
Explanation:
Charges on ions are determined by the ratio of electrons to protons. Neutral elements have the same number of protons and electrons. Remember: protons have a positive charge and electrons have a negative charge. However, based on the amount of electrons these elements have, some are more or less willing to give up their electrons to participate in ionic bonding. Potassium usually gives up 1 electron because this satisfies the octet rule. By removing this electron, the element has more protons than electrons, giving it an overall +1 charge.
Answer: No that is false.
Explanation: There are 6 basic elements of life here they are. Have cells, have chemicals, respond to stimuli, reproduce, grow and develop, and use energy.
