Answer: 73 m is equal to 730 dm

Explanation:

Meter and decimeter are the units which are used to express the length of an object.

These two units are interchangeable.

To convert meter into decimeter, we use the conversion:

1 meter = 10 decimeter

We are given the value of length is 73 m

Converting this into decimeter, we get:

$\Rightarrow (73m)\times (\frac{10dm}{1m})\\\\\Rightarrow 730dm$

Hence, 73 m is equal to 730 dm

Calculate the mass of vanadium(V) oxide (V2O5) that contains a million (1.0 *10^6) vanadium atoms. Be sure your answer has a uni

sweet [91]

Answer : The mass of vanadium(V) oxide will be $1.51\times 10^{-16}g$

Explanation : Given,

Number of atoms of $V_2O_5$ = $1.0\times 10^{6}$

Molar mass of $V_2O_5$ = 181.88 g/mole

In $V_2O_5$ , there are 2 atoms of vanadium and 5 atoms of oxygen.

First we have to determine the moles of $V_2O_5$ .

As, $2\times 6.022\times 10^{23}$ number of vanadium atom present in 1 moles of $V_2O_5$

So, $1.0\times 10^{6}$ number of vanadium atom present in $\frac{1.0\times 10^{6}}{2\times 6.022\times 10^{23}}=8.3\times 10^{-19}$ moles of $V_2O_5$

Now we have to determine the mass of $V_2O_5$ .

$\text{Mass of }V_2O_5=\text{Moles of }V_2O_5\times \text{Molar mass of }V_2O_5$

$\text{Mass of }V_2O_5=(8.3\times 10^{-19}mole)\times (181.88g/mole)=1.51\times 10^{-16}g$

Therefore, the mass of vanadium(V) oxide will be $1.51\times 10^{-16}g$

Answer:

Q1: 1.67 L.

Q2: Saturated solution.

Explanation:

Q1:

We have the role that the no. of millimoles before dilution is equal to the no. of millimoles after dilution.

(MV) before dilution = (MV) after dilution

M before dilution = 10.0 M, V before dilution = 0.5 L.

M after dilution = 3.0 M, V after dilution = ??? L.

∴ V after dilution = (MV) before dilution / M after dilution = (10.0 M)(0.5 L) / (3.0 M) = 1.67 L.

Q2:

From the given curve, it is clear that the solubility of sodium nitrate at 35.0°C is 100 g per 100 g of water.

So, the mentioned solution is a saturated solution at this T.

A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent.

water and ammonia are polar. The hydrogen atoms in each have a slight positive charge. What does that tell you about the oxygen

Andreas93 [3]

Answer:

More electronegative

Explanation:

The oxygen and nitrogen in ammonia shows that they are more electronegative than the hydrogen atoms.

Electronegativity shows the affinity of an atom for valence electrons.
Electronegativity is the measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.

The oxygen atom in water and the nitrogen atom in ammonia are more electronegative.

They attract the electrons more and they then become negatively charged.

The hydrogen will then become positively charged in the shared covalency.

Answer:

The solution's new volume is 1.68 L

Explanation:

Dilution is the procedure to prepare a less concentrated solution from a more concentrated one, and simply consists of adding more solvent. So, in a dilution the amount of solute does not vary, but the volume of the solvent varies.

In summary, a dilution is a lower concentration solution than the original.

The way to do the calculations in a dilution is through the expression:

Ci*Vi=Cf*Vf

where C and V are concentration and volume, respectively; and the i and f subscripts indicate initial and final respectively.

In this case, being:

Ci= 7 M
Vi= 0.60 L
Cf= 2.5 M
Vf=?

Replacing:

7 M*0.60 L= 2.5 M* Vf

Solving:

$Vf=\frac{7 M*0.60 L}{2.5 M}$

Vf= 1.68 L

The solution's new volume is 1.68 L
