Answer:
The new pressure is 2, 74 atm
Explanation:
We apply Boyle Mariotte's law, where for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1 = P2xV2 P2=( P1 x V1)/V2 1 L-----1000L--->( 140ml/1000ml)x1L=0,140 L
(50ml/1000ml)x 1L =0,050L
P2= (0,980 atm x 0,140 L)/0,050L= 2, 744 atm
Answer: I don’t think the answer is A or C. Maybe B.
The word chemosynthesis means
the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
Explanation:
The atomic radius of main group elements generally increases down a group because as there are more electrons they are farther away from the nucleus and the electrons closer to the nucleus shield the outer electrons from the protons for attraction.
Answer: 1: B. It will speed up the reaction.
2: A. Increase the concentration of a reactant.
3: A. They act as catalysts.
4: C. A catalyst decreases the activation energy needed for a reaction.
5: D. collision theory.
