Answer:
If the earth had on Axis, there will be no seasons.
When something about the size of mars clashed with Earth about 4.5 billion years ago, it hit off a piece that became the moon.
We are asked in the problem to convert teh unit mci or millicurie to another unit of radioactivity, becquerel. The conversion to be used in this case is <span>1 millicurie [mCi] = 37,000,000 becquerel [Bq] .The problem gives 15 mCi which when multiplied to </span>37,000,000 is equal to 5,550,000,000 bQ
The amount of sugar in a liquid can be measured using a laser pointer and a prism. Basically, you utilize Snell's Law:
n_i*sin(θi) = n_r*sin(θr), where,
n_i = index of refraction of the incident medium
n_r = index of refraction of the refractive medium
θi = <span>angle of incidence
</span>θr = <span>angle of refraction
</span>
You make use of the laser pointer, prism, and sugar solutions in various known concentrations. You then graph the sugar concentration versus the angle of refraction. You can then determine the amount of sugar in a liquid after determining the angle of refraction of that unknown sugar solution.
Ionic bonds are made up of a metal and a nonmetal elements while covalent bonds are are made up of two metal. So, you can just look at the periodic table and identify which compounds have two metals and which have one metal and one nonmetal. Also, those compounds with high electronegativity difference are very likely to be ionic while the opposite is covalent. HOWEVER, some compounds can be both covalent and ionic. For instance, if HCI gas is at higher temperatures, then it is ionic while it would be covalent at room temp.
Hope I've helped.

Answer:
yes....
Explanation:
Let me explain the molecular orbital diagram of N2 using its diagram.
one atom of nitrogen has 7 electrons so a N2 molecule will have 14 electrons
so first 2 electrons go in 1s sigma bond
next 2 in 1s sigma anti bond orbital
next 2 in 2s sigma bond orbital
next 2 in 2s sigma anti bond orbital
next 2 in 2pz sigma bond( assuming that z axis is the internuclear axis ) orbital
