Explain why Noble Gases (group 18 elements) have little/no electronegativity
Answer: they don't have values there because they aren't on the pauling scale of electronegativity, as they don't form any compounds with other elements. However, argon and neon can technically form compounds with other elements; it is just extremely unlikely.

Choose the answer that best explains why Orion is important to star watchers.
Orion is located on the celestial equator. Its location causes the rest of the stars to appear to revolve around Orion as the Earth rotates.
Since Orion can be seen in both the Southern and Northern Hemispheres it is useful for finding north in the night sky.
Orion, the hunter, was an important figure in Greek Mythology making the constellation of central importance to astronomers.
Orion is easy to locate, it can be seen in both hemispheres and is helpful for locating prominent stars, nebulas and surrounding constellations.
Answer:
Orion is located on the celestial equator. Its location causes the rest of the stars to appear to revolve around Orion as the Earth rotates.
Explanation:
The above stated statement is the reason why those who watches for stars commonly called the star watchers use the Orion as their base point in star observation. Without this, it would be difficult to trace the stars or know the exact ones which appears on the sky.

A compound is found to have a composition of 35.880% Cr, 21.076% P, and 43,545% O
What is the empirical formula of the compound?
Explanation:
Cr=35.880/51=0.73≈0.7
P=21.076/31=0.67≈0.7
O=43.543/16=2.71
Divide each by 0.7 u get
Cr=1 ,P =1, O=4
Empirical formula is CrPO4

Answer:
Cl2 + 2NaBr --> 2NaCl + Br2
Explanation:
This is a single displacement reaction where one side of the ionic compound switches with the other.
So, Cl2 + NaBr ---> NaCl + Br2
This isolates the Bromine and puts the Chlorine in it's place.
Then, balance out the equation like so and you should get
Cl2 + 2NaBr --> 2NaCl + Br2
Why are we pulled to the center of the Earth and not into the much larger sun?
Answer:
The sun's gravity pulls on the earth, and the earth pulls back on the sun at the same time. This is why the center of the solar system is not the center of the sun. As one gravitational body gets bigger than the other, it circles closer to the center of the system (shown in red).
Explanation:
hope this helps...
The earth is known to be falling towards the sun as a result of intense gravity. The earth is known to have plenty of sideways momentum and due to this sideways momentum, the earth is often falling towards the sun and missing it.
The reason we are pulled to the center of the Earth and not into the much larger sun by gravity is that all objects with mass, like our Earth, do bend and curve the fabric of the universe referred to as spacetime.
At most, the gravity from the sun result in our planet moving in a curved, elliptical path. but, the planets are moving fast enough so that they are not pulled into the sun.
The sun has a more weaker gravity and as it loses mass, it causes the Earth to slowly move away from it.

Under each DNA sequence write the complimentary mRNA base sequence that each of these gene fragments would produce. Remember that in the production of mRNA, the DNA base sequence "A" _________________ specifies the RNA base ____________________
Answer:
The correct answer would be -
Thymine to adenine
Cytosine to guanine
guanine to cytosine
Adenine, and "U" uracil respectively.
Explanation:
mRNA is a sequence of complementary base sequences encoded from a gene or DNA segment which is used to produce the protein by the process called translation.
From converting a sequence from DNA to its complementary mRNA sequence, the rules of complementary base pairing will be applied: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A) and Thymine is replaced by adenine.

Which compound is insoluble in water?
A) calcium bromide
B) potassium bromide
C) silver bromide
D) sodium bromide
Answer:
C) silver bromide
Explanation:
Calcium bromide is incorrect.
The compound which is insoluble in water is silver bromide (AgBr).
Which compounds are insoluble in water?Those compounds which have high attraction force between their constitutes ions as compare to ions between the water and compounds are insoluble in water.
Among given compounds all are soluble in water except silver bromide, because silver is having high nuclear charge than other given alkali metals as calcium, potassium and sodium. So it tightly attracts the bromide ion towards itself and this attraction is more than the attraction between the H⁺ ion of water and bromide ion, as a result of which it is insoluble in water.
Hence, option (C) is correct i.e. silver bromide.
