Answer : Option B) A Comet

Explanation : A comet is mainly composed of rock, dust, ice and frozen gases like carbon monoxide, carbon dioxide, methane, and ammonia. It is sometimes called as dirty snowballs, recent studies on comets have revealed that the ice of a comet is covered by a crust. Comets also contain many variety of organic compounds as well as the gases.

Comets when comes near the sun while revolving around it loses some of the ice from its crust which gets vaporized by sun's heat.

This is very tricky. An Asteroid is made out of rock metals and other stuff. A comet is mainly made out of ice and dust. A Meteorite is made out of minerals that contain some metal. Planet is not obviously it. So the correct answer is B.

What is T2, if T1= 500 k, v1=10L, V2=8L,P1=600 torr,P2=200 torr?
Molodets [167]

Answer:

T2 = 133.333°K

Explanation:

Using Combined Gas Laws:

(600 torr)(10L)/500°K = (200 torr)(8L)/x°K

\frac{600 torr(10L)}{500K} =\frac{200 torr(8L)}{xK}

Cross multiply:

x°K (600 torr)(10L) = 500°K(200 torr)(8L)

Divide:

x°K = (500°K(200 torr)(8L))/(600 torr)(10L)

xK = \frac{500K(200 torr)(8L)}{600 torr(10L)}

x = 400/3°K or 133.333°K

please help I don’t understand the difference between ammonium and ammonium ion. I possibly did 9.a) correct but part b is a bit
ozzi

You may find the electron diagram of ammonia and the ammonium ion in the attached picture.

Explanation:

Ammonia NH₃ have covalent bonds with the hydrogen atoms in which for each bond one electron comes from nitrogen atom (blue dot) and the other from the hydrogen atom (red dot). You may see that the nitrogen remains with the lone pair of electrons that does not participate in bonding.

Ammonia NH₃ have a basic character and is able to accept a proton H⁺ from an acid to form the ammonium ion NH₄⁺. The fourth bond formed its called a coordinative-covalent bond that is created only with the nitrogen lone pair of electrons (blue dots).
