A sealed cylinder with a movable piston contains exactly 1 mole of an ideal gas at 25°C. The pressure of the gas is held constant at 1 bar. When the temperature of the cylinder is doubled one of the following describes what happens: a. The pressure halves​
b. The pressure doubles and the number of moles remains the same
c. The number of moles halves and the pressure doubles
d. The number of moles remains the same and the pressure remains constant

one state would change   like louisiana to texas. thats a change

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
