Three different atoms or atomic cations with 3 electrons.

Chemistry
1 answer:
sveticcg [70]2 years ago
6 0

Answer:

Li, Be^+, B^{2+}

Explanation:

To answer this question successfully, we need to remember that atoms are neutral species, since the number of protons, the positively charged particles, is equal to the number of electrons, the negatively charged particles. That said, we may firstly find an atom which has 3 electrons (and, as a result, 3 protons, as it should be neutral).

The number of protons is equal to the atomic number of an element. We firstly may have an atom with 3 protons and 3 electrons (atomic number of 3, this is Li).

Similarly, we may take the atomic number of 4, beryllium, and remove 1 electron from it. Upon removing an electron, it would become beryllium cation, Be^+.

We may use the same logic going forward and taking the atomic number of 5. This is boron. In this case, we need to remove 2 electrons to have a total of 3 electrons. Removal of 2 electrons would yield a +2-charged cation: B^{2+}.

How can exposoure to high energy waves be both harmful and helpful to cells??
belka [17]
Exposure to high energy waves can be helpful to cells by damaging DNA in cells, meaning if somebody were to have cancer cells it breaks down the bad cells and it can shrink tumor. It can be harmful by damaging skin cells, which we need as our first line of defense. Meaning, it could cause skin cancer. Hope this helped!

Al(s) + NiSO4(aq)<br> Balance
irinina [24]

Answer:

2Al(s) + 3NiSO4 --> Al2(SO4)3 + 3Ni

Explanation:

This reaction type is a single replacement. The format of a single replacement is:

A+BC --> B+AC

A= Al

B= Ni

C= SO

The coefficient 3 for Ni would become a subscript for  AC. After you plug those into the reaction you need to count how many of each are on the left side and try to get the same number on the right side. Both sides must be equal to have a balanced equation.

What is refraction? * Bending of light<br> Reflection of light
sdas [7]
Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light. Hope this helps!

How do I find the moles of OH- which reacted (mol) in the titration. Table Attached
BaLLatris [955]

Answer:

It is equal to the number of moles of acid that reacted. When Oxalic acid is your limiting reactant it is the # of moles of oxalic acid used. When NaOH is your limiting reactant it is equal to the number of moles of NaOH used.
