Explanation:
to find mL we must cancel grams we do this by the equation:
20/1.41 = 14.2 mL
Answer:
physical
Explanation: water can change from solid to liquid to a gas
The answer would be bromine because electronegativity increases as you move up and to the right on the periodic table, and if you keep moving right you will see that bromine has the highest electronegativity out of those four elements.
Answer is: <span>it comes at the right time.
Some of the chemistry discoveries that come in right time (with enough informations, knowledge and right technology to use that discovery) are: </span>Periodic Table of the Elements, discovery of electron, proton, neutron, radioactivity, pasteurization, t<span>he Haber-Bosch process.</span>
