Answer:
Carbon Tetrachloride
Explanation:
1 Carbon atom, 4 chlorine atoms (hence "tetra" prefix)
Answer : J. J. Thomson’s experiment disproved the theory that an atom is indivisible.
Explanation : Scientist J.J. Thomson did his experiment to prove the existence of electrons. He did the experiment using a cathode ray tube, in which a vacuum-sealed tube with a cathode and anode on one end was placed which created a beam of electrons that traveled towards the other end of the tube. This was the theory that proved that atoms consists of many subatomic particles namely electrons.
Answer:
11.4 moles
Explanation:
Your chemical equation for the reaction of zinc and nitric acid will be
Zn + 4 HNO₃ --> Zn(NO₃)₂ + 2 NO₂ + 2 H₂O
To solve the problem, you need to use stoichiometry. For every 1 mole of zinc, you will need 4 moles of nitric acid. Divide 45.60 by 4. Your answer should be 11.4 moles.
True should be the correct answer
