Mark is pushing a box down the hall. Mark is using 5N to push the box 20m. How much work is Mark doing?

Answers

The work by Mark : 100 J

Further explanation

Work is the transfer of energy caused by the force acting on a moving object  

Work is the product of force with the displacement of objects.  

Can be formulated  

[tex]\tt W=F\times d[/tex]

W = Work, J, Nm  

F = Force, N  

d = distance, m  

Mark is using 5N to push the box 20 m,

F = 5 N

d = 20 m

[tex]\tt W=5\times 20\\\\W=100~J[/tex]

A student mixed several different 12 mm plastic beads together by mistake. Luckily the beads had different densities. One group of beads had a density of 0.6 g/cm3; the other beads had a density of 1.2 g/ cm3. Describe a method the student can use to sort the beads.

Answers

Answer:

The answer is "Each student will get a glass of water and drop the bead into it  but the beads float 0.6 g / cm3 and slip down to 1.2 g / cm3

".

Explanation:

One's masses would've been dissimilar, even though their width and concentrations were also equal. Whenever the type-A mass is m,  then the type-B mass is 2 m. One should measure then, therefore.  

Water has a 1g / cm^3 density. Although Type A is higher than air, Type B is much more compact. it means will float if they place  it in water type-A where type-B sinks.

No, it has the wrong number of valence electrons. The correct number is: No, it has the right number of valence electrons but doesn't satisfy the octet rule. The symbols of the problem atoms are:*

Answers

The question is incomplete, the complete question is shown in the image attached.

Answer:

1) No, it has the right number of valence electrons but does not satisfy the octet rule.

2) Yes

3) No, it has the wrong number of valence electrons, the correct number is 16

Explanation:

If we look at the first structure in the image(HCN), it easy to see from inspection that nitrogen has three valence electrons as it is normally supposed to have. However, if we count all the electrons around nitrogen, we will notice that they are six instead of eight. Thus nitrogen has not satisfied the octet rule here.

The structure HBr satisfies the octet rule, hence it is a reasonable Lewis structures for the compound shown.

CO2 has 16 valence electrons but the structure shown contains about 20 valence electrons hence it is not a reasonable Lewis structure for the compound.

Yes, in HCO⁺ the proposed lewis structure is reasonable.

No, COCl₂ has the wrong number of valence electrons.

No, OH⁻ has the right valence electron but does not obey the octet rule.

The correct structure for the question can be seen in the image attached below.

In the proposed structure, the number of valence electrons in HCO⁺ is: ( 1 + 4 + (6-1) ) = 10e⁻

Thus, the atoms obey the octet rule and the number of calculated valence electrons corresponds with what we have in the given structure.

Yes, the structure is correct and reasonable.

In COCl₂, the central carbon bonding to the oxygen is supposed to be doubly bonded and not singly bonded.the number of valence electron in COCl₂ is: ( 4 + 6 + (7 × 2)) = 24e⁻

The calculated number of valence electrons is different from the given structure of 26e⁻, so we can say No, it has a wrong number of valence electrons.

In the third structure, oxygen is supposed to have three lone pairs of electrons in order to obey the octet rule.the number of valence electrons in the structure is: (6 + (1+1) = 8e⁻

But both H, as well as, O do not obey the octet rule. Therefore, we say No, it has the right number of valence electron but do not obey the octet rule.

can someone explain what radioisotopes are?

Answers

Answer:

A radioisotope is a radioactive isotope.

Explanation:

On the Periodic Table, elements 92 and up are radioactive. So that is Uranium and any higher elements. Remember that radioactive elements love to decay and are dangerous.

Isotopes are different forms of an element. For instance, we could have different amount of neutrons in the same element (same number of protons).

We could have an element like He - 4 vs. He - 6, where He - 4 would have 2 neutrons and He - 6 would have 4 neutrons.

So a radioisotope would be an elemental isotope that is radioactive. A good example of this is Uranium.

We have thousands of different isotopes of Uranium, but 2 are well known: Uranium - 235 and Uranium - 238. Both are the same element with the same amount of protons, but both have a different amount of neutrons.
