What happens when warm air rises? (5 points)

Alika [10]

The movement creates a difference in air pressure.

When warm air rises it goes up to top of atmosphere.
The cold air remains at bottom.
Which makes a blank space in between.
To fill that space air comes from all sides
Which makes difference in pressure.
It becomes reason for creation of Tornado, hurricane,Cyclones etc

A 25.0 ml solution of .0600 M EDTA was added to a 57.0 ml sample containing an unknown concentration of V3+. All V3+ present for

Rom4ik [11]

Explanation:

Let us assume that the ratio for the given reaction is 1:1.

Therefore, we will calculate the moles of $Ga^{3+}$ as follows.

Moles of $Ga^{3+}$ solution = molarity × volume (L)

= 0.0440 M × 0.014 L

= 0.000616 moles

Moles of excess EDTA = 0.000616 moles

Also, the initial moles of EDTA will be calculated as follows.

Total initial moles of EDTA = 0.0600 M × 0.025 L

= 0.0015

Therefore, moles of EDTA reacted with $V^{3+}$ will be as follows.

= 0.0015 - 0.000616

= 0.00088 moles

Since, we have supposed a 1 : 1 ratio between $V^{3+}$ and EDTA .

So, moles of $V^{3+}$ = 0.00088 moles

Now, we will calculate the molarity of $V^{3+}$ as follows.

Molarity of $V^{3+}$ solution = $\frac{\text{moles}}{\text{volume (L)}}$

= $\frac{0.00088 moles}{0.057 L}$

= 0.015 M

Thus, we can conclude that the original concentration of the $V^{3+}$ solution is 0.015 M.

How many atoms are there in 10.2 moles of Phosphorous?

nikdorinn [45]

There are 2.06 x 10²⁴ atoms

<h3>Further explanation </h3>

The mole is the number of particles (atoms, molecules, ions)contained in a substance

1 mol = 6.02.10²³ particles

Moles can also be determined from the amount of substance mass and its molar mass

number of atoms :

$\tt 10.2\times 6.02\times 106{23}=2.06\times 10^{24}$
