Answer:

Option C

Explanation:

From the question we are told that:

Difference in energy \delta E =3.49 * 10^{-17} J

The Ground state Difference in energy at n=1

\delta E_g = 2.18 * 10^{-18} × Z^2

Generally the equation for Difference in energy is mathematically given by

\delta E=\delta E_g

Therefore

3.49 * 10^{-17} = 2.18 * 10^{-18} * Z^2

Z^2=16

Z=4

Therefore

Charge on element Z Q_Z

Q_Z= Atomic\ no\. of\ element - No.\ of\ electrons\ of\ element

Q_Z =4-1

Q_Z=+3

Option C

What is the volume of 3.66 x 1032 molecules of fluorine gas at STP?
kipiarov [429]

Answer:

1.36x10^10L

Explanation:

Step 1:

Determination of the mole of fluorine that contains 3.66x10^32 molecules. This is shown below:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This implies that 1 mole of fluorine also contains 6.02x10^23 molecules.

Now if 1 mole of fluorine contains 6.02x10^23 molecules,

Therefore, Xmol of fluorine will contain 3.66x10^32 molecules i.e

Xmol of fluorine = 3.66x10^32/6.02x10^23

Xmol of fluorine = 6.08x10^8 moles

Step 2:

Determination of the volume occupied by 6.08x10^8 moles of fluorine.

1 mole of any gas occupy 22.4L at stp. This means that 1 mole of fluorine also occupy 22.4L at stp.

Now if 1 mole of fluorine occupies 22.4L at stp,

Then 6.08x10^8 moles of fluorine will occupy = 6.08x10^8 x 22.4 = 1.36x10^10L

A. Acid rainfall will cause a decrease in oceanic surface temperatures.
laiz [17]

Answer:

Increased atmospheric carbon dioxide will cause increased ocean surface temperatures.

Explanation:

Greenhouse gases of which CO2 is a typical example are known to cause a gradual and steady increase in the surface temperature of the earth by trapping infrared rays close to the surface of the earth.

As the surface temperature of the earth rises, the surface temperature of the oceans rises also leading to the tendency towards hurricanes.

Hurricanes are violent storms which are known to form near the equator over warm ocean waters.

Hence, increased atmospheric carbon dioxide will cause increased ocean surface temperature which in turn increases the chances of the occurrence of hurricanes.

Will give brainliest, points, and more!!
tino4ka555 [31]

Do you relizes how many activities lead to global warming? When gas is burned in a car, it produces carbon dioxide (a green house gas). The carbon dioxide then floats up towards the atmosphere and becomes part of the atmosphere. This then causes the heat from the sun to get trapped, bouncing from the atmosphere to the earth. The sun will never stop producing heat which will only lead to the world getting hotter as each decade goes by.  

Hope this helps you!
