Which of the following notations is the correct noble gas configuration for Li

Answers

Noble gas configuration for Li : [He]2s¹

Further explanation

In an atom, there are levels of energy in the shell and sub-shell

This energy level is expressed in the form of electron configurations.

Lithium with atomic number 3, then the electron configuration:

1s²2s¹

And for noble gas configuration or it can be called Condensed electron configurations :

[He]2s¹

Answer:

[He]2s¹

Which metal is more active than NI and less active than Zn?1. Cu
2. Cr
3. Mg
4. Pb

Answers

Answer : The correct option is, (2) Cr (Chromium)

Explanation :

The reactivity series of metal are arranged of the reactivity from the highest to the lowest. Reactivity series is used to determine the products of the single displacement reactions. In the single displacement reaction, the most reactive metal displaces the least reactive metal.

From the given reactivity series we conclude that there are two metal (Mg and Cr) are more reactive metal than the Ni and there are two metal (Pb and Cr) are less reactive metal than the Zn. So, the Cr (Chromium) is the metal which is more active than Ni and less active than Zn.

Hence, the correct option is, (2) Cr
Cr is more active than nickel and less active than zinc.

Which is classified as a renewable resource? A. coal B. wind C. oil D. uranium

Answers

The answer is B) Wind because wind will always be available, while coal, oil and uranium are objects we are digging up. This makes wind a renewable resource, therefore it is better for the environment because we can theoretically never run out of it. This is the reason we are starting to use wind to create energy; we can use it again.
The answer is obviously B. It is the only one that can continually be renewed without fail. 

Why do minor parties have difficulty succeeding in the United States electoral system? A. tend to focus on only a single issue B. quickly join forces with the wrong party C. views are usually tied to strict religious doctrine D. seldom are given the respect from foreign officials they need to get elected

Answers

I think the best answer is D. Minor parties do not always get a support from foreign officials in order for them to get elected. They also have difficulties because they are a small political party. They do not have enough resources or supporters as compared to larger political parties.

Explain a polar molecules and give examples​

Answers

Ethanol is polar because the oxygen atoms attract electrons because of their higher electronegativity than other atoms in the molecule. Thus the -OH group in ethanol has a slight negative charge. Ammonia (NH3) is polar. Sulfur dioxide (SO2) is polar.

What is the mass of 2.65 millimoles of sulfur?

Answers

Divide this problem in to two steps: 1. Convert millimoles to moles. 2. Convert moles to grams.

1.
2.65 mlmol x 1mol/1000mlmol=.00265mol

2.
.00265mol x 32.065g/1 mol=.0850g S

Let me know if you need more explanation on why I used the conversions that I did.
