Answer:
Blue Litmus will change into red if it is added in sodium hydroxide
Explanation:
Answer: No
Explanation: Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.
Organic chemistry was definitely harder for me, though this is a matter of opinion and learning style. If you are good with logic, then organic chemistry might not be so hard, or at least that's what my professor said. A lot of physics was just knowing how to use formulas and then plugging and chugging, and knowing basic outcomes of physical reactions. It's a whole other story if you take calculus based physics.
Good luck.
Answer:
1.23 atm
Explanation:
Given data
- Initial pressure (P₁): 1.0 atm
- Initial volume (V₁): 750 mL
- Final pressure (P₂): to be calculated
- Final volume (V₂): 610 mL
For a gas sample, <em>there is an inverse relationship between the pressure and the volume</em>, that is, when the pressure is increased, the volume decreases. Mathematically, for an ideal gas at constant temperature, we can find the final pressure using Boyle's law.
Okay, so the atomic mass of Cl2 is 35.5, so all you would have to do is multiply that by 2 to get 71.
