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:The units of molarity are M or mol/L. A 1 M solution is said to be “one molar.”
Explanation:
Answer:
A hydrogen molecule forms from two hydrogen atoms, each with one electron in a 1 s orbital. The two hydrogen atoms are attracted to the same pair of electrons in the covalent bond. The bond is represented either as a pair of “dots” or as a solid line. Each hydrogen atom acquires a helium-like electron configuration. Shared electrons located in the space between the two nuclei are called bonding electrons. The bonded pair is the “glue” that holds the atoms together in molecular units. The hydrogen molecule is the simplest substance having a covalent bond.
Explanation:
Answer:
The correct answer is A.
Explanation:
Electrical potential energy is a type of potential energy that results from the Coulomb force and is associated with point loads in a defined system.
For a point charge in the presence of an electric field E produced by another point charge Q, electrostatic potential energy is defined as the negative of the work done by the electrostatic force to carry the charge from position A to position B: mathematically this is a line integral.
The electric field is conservative, and, for a point charge, it is radial, so the work is independent of the trajectory.
