Answer:

7.23 x 10^24 atoms

Explanation:

Use Avogadro's number that states that there are 6.022 x 10^23 particles in one mole:

12 mol O x (6.022 x 10^23) atoms = 7.23 x 10^24 atoms

Answer:  The intertidal or littoral zone maintains a balance between the land and the sea. It provides a home to specially adapted marine plants and animals.

Explanation: The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.

Explanation:

Molar mass of Na=23g/mol

amount of mole(n)=3

mass=?

therefore,n=m/M

3mol=m/23g/mol

m=23g/mol ×3mol

m=69g.

3 Ca3 (PO4)2 + 4 CaO

So we can see that there are 3 Ca3 (Ca3, Ca3, Ca3), which means you multiply the subscript by the coefficient, meaning 9 Ca. Then we see (PO4)2, which means that there are two PO4 (PO4, PO4) so we multiply the subscript 2 by the subscript 4 on O to equal 8 O, and we multiply the subscript 2 by the subscript 1 on P (the 1 is not written) to equal 2 P.

So far we have 9 Ca, 8 O, and 2 P.

One last term, 4 CaO (means CaO, CaO, CaO, CaO) which translates to 4 Ca and 4 O.

Add them all together and you get (9+4=13) 13 Ca, (8+4=12) 12 O, and 2 P

Explanation:

Using Charles Law ,

[tex]\frac{V1}{T1}=\frac{V2}{T2}[/tex]

Using this formula we have ,

V1= 200cm^3

T1=40+273.15 = 313.15 K

T2 = 100+273.15 = 373.15 k

V2= ?

Hence using above formula simplify it we will get ,

V2 = 238.3 cm^3

Explanation:

There are some climates in which there are no living things. The average of the weather is the climate.

Climate is a region's averaged long-term weather pattern over a period of time, usually 30 years. More precisely, it is the average and variation of climatic variables over a period of time that can range from a few months to many millions of years.

Every element of our life is impacted by the climate, including our food supplies, transportation systems, clothing choices, and vacation destinations. It significantly affects our future, our health, and our means of subsistence. Climate is the long-term trend of the weather in any given location.

As an illustration, you can anticipate snow in the Northeast in January or hot and muggy weather in the Southeast in July. Climate is this. Extreme values, such as record-breaking high temperatures or heavy rainfall, are also part of the climatic record.

Thus, there are some climates in which there are no living things.

2. orbit

3. potential energy

4. magnetic field

5. net force

6. B; repulsion

7. A; copper

8. B; there is no gravitational attraction between you and the cup, but Earth's gravity is stronger, so Earth's gravity pulls the cup down

9. A; the net force is acting in an upward direction

Explanation:

The controlled variable is what stays constant throughout an experiment. You use the controlled variable to compare the new data to see what happened during whatever reaction you could say.

Answer:

It is an covalent bond.

Explanation: The bond is covalent because all the dots are equaled to each other therefore creating a stable bond. When the bonded atoms have a lower total energy than that of widely separated atoms, a covalent bond forms. The electrons are not moved from one atom to the other in polar covalent bonds, such as that between hydrogen and oxygen atoms, as they are in an ionic bond.

Answer:

3). 1.30 × 10^(24) molecules

Explanation:

From avogadro's law which state that equal volume of all gases at the same temperature and pressure contain the same number of molecules.

We can relate it to this question as;

V₁/n₁ = V₂/n₂

Where;

V₁ is initial volume

n₁ is initial number of molecules

V₂ is final volume

n₂ is final number of molecules

Thus at STP, we have V₁ = V₂ and as such Plugging in the relevant values gives;

5/(1.30 x 10^(24)) = 5/n₂

n₂ = 1.30 x 10^(24) molecules
