Answer:

Option "B" is correct.

Explanation:

According to VSEPR theory, There are repulsion forces exists among the bond pair - bond pair or bond pair - lone pair of electrons. In NH_{3} and  CH_{4}, the number of electron pairs are same but methane has all the four bond pairs where in ammonia, three bond pairs and one lone pair exists. And thus there are repulsion forces possible in between the lone pair and bond pair of electrons thus the arrangement of electron pairs around both the molecules is same or different depending up on the conditions leading to maximum repulsion.

What is the mass in grams of 2.0 moles of NO2
mote1985 [20]
Use your periodic table to get 1 mol. Look up the atomic masses. I'll round the numbers since every periodic table is different.
 
N = 14
O2 = 2 *16
Total = 30 grams / mol


Therefore 2 mols = twice as much = 60 grams.

if a substance causes another substance to be oxidized, that substance is a(n) agent. likewise, the substance that is oxidized i
Inessa [10]

If a substance causes another substance to be oxidized, that substance is an oxidizing agent. Likewise, the substance that is oxidized in an electrochemical reaction is always the reducing agent.

An Oxidizing agent is the one that gets reduced by accepting electrons. It causes oxidation because it makes the other substance lose electrons.

Oxidizing agents also transfer one electronegative atom like oxygen to the other chemical substance. Halogens are an example of oxidizing agents.

A reducing agent is the one that gets oxidized because it loses electrons in a redox reaction. It loses electrons and achieve a higher oxidation state. Lithium is an example of a reducing agent.

Why are the New Moon and Full Moon considered opposites of each other?
Sergio [31]
The full moon shows all of one side of the moon in pictures it is all white. In a new moon you can't see the moon cuz it's all dark and in pictures it is all black. Thus becoming opposites of each other.
