Answer 1

Explanation:

cooling

communication

heating

motion

Answer 2

Answer:

I believe it's all of the above

Explanation:

Because heating and cooling can be done by an AC unit, which takes electricity. Communication also takes electricity, along with lighting (especially if we're talking light fixtures to light up homes). Not to mention motion, such as cars and other transportation uses, believe it or not, electricity.

Hope this helped, also please tell me if I'm wrong.

Answers

• Biodiversity is essentially diversity of genetics
• An ecosystem refers to multiple species
• A large population of one species is a decent answer but not the best because more species would have more diverse genetics
• Lots of traits in one species is basically the same as the above bullet point
• Not having seasons could help but not necessarily
• So our best answer is a large community of organisms

How many moles of carbon atoms are there in
5g of carbon?

Answers

Answer:

12 atoms of carbon

Explanation:

(6.023X10^23)/12 atoms of Carbon.

There are 0.42 moles of carbon atoms in 5g of carbon.

HOW TO CALCULATE NUMBER OF MOLES:The number of moles in a substance can be calculated by dividing the mass of the substance by its molar mass. That is;

no. of moles = mass (g) ÷ molar mass (g/mol)

According to this question, the mass of carbon is 5g. The molar mass of carbon is 12g/mol.

No. of moles = 5g ÷ 12g/mol

No. of moles = 0.42moles

Therefore, there are 0.42 moles of carbon atoms in 5g of carbon.

Which change is likely to happen to an atom of the element strontium (Sr) during bonding?

(1 point)

It will gain electrons, forming a positive ion.
It will gain electrons, forming a positive ion.

It will give up electrons, forming a negative ion.


It will give up electrons, forming a positive ion.


It will gain electrons, forming a negative ion.

Answers

Answer: It will give up electrons, forming a positive ion.

During bonding, strontium atom will give up electrons, forming a positive ion.

STRONTIUM:

Strontium (Sr) is an element in group 2 of the periodic table. Just like every other element in group 2, strontium posseses two valence electrons in its outermost shell.

Strontium will undergo bonding with other atoms by losing its two (2) valence electrons to form a cation i.e. a positively charged ion.

Therefore, strontium atom will give up electrons, forming a positive ion when it undergoes bonding.

Which property accounts for the fact that atoms can be identified by an examination
of the emission spectrum?
A. Each kind of atom has a different mass number.
B.Each kind of atom has a different atomic number.
C.Each kind of atom has a different isotopes.
D. Each kind of atom has a characteristic difference in energy levels for electrons.

Answers

Answer:

Explanation:

D is the answer

Each kind of atom has a characteristic difference in energy levels for electrons, this property accounts for the fact that atoms can be identified by an examination, therefore the correct answer is option D.

What is the photoelectric effect?

It is the process of emission of electrons from the material because of absorption of electromagnetic radiation in form of photons of light waves.

The photoelectric effect explains the particle behavior of the light waves.

Each kind of atom has a characteristic difference in energy levels for electrons this fact can be used to identify the different atoms by using inspection.

Thus, the correct answer is option D.
