Consider the following balanced reaction between hydrogen and nitrogen to form ammonia:

1 answer:

8 0

Three moles of H2 produce 2 moles of NH3. Since the reactinng ratios are constant, then the ratio of hydrogen consumed:ammonia is 3:2
Mathematically, 3 Mol H2=2mol NH3
19 Molly H2=?
Cross-multiplying gives;
(19*2)/3=12.67 moles

If you purchased 0.610 μCi of sulfur-35, how many disintegrations per second does the sample undergo when it is brand new?Expres

ASHA 777 [7]

Answer:

the sample undergo $1.67 \times 10^5$ disintegrations per second.

Explanation:

Given:

The amount of sulphur purchased is 0.671 μCi

To find:

disintegrations per second = ?

Solution:

Some of the conversions are

$1 Ci = 3.8 \times 10^{10} Bq$

1 rad = 0.01 Gy

1Gy = 1 j/kg tissue

1 rem = 0.01 Sv

1Sv = 1 j/Kg

Using these conversions,

The decay rate of this sample is calculated as

$0.671 \mu C i \times \frac{1 \mu C i}{10^{6}} \mu C i \times \frac{0.671 \times 10^{10}}{1 \mu C i}$

= $1.67 \times 10^5$ disintegrations per second

create visual representations that show the interactions between the particles in both samples during vaporization

ivolga24 [154]

Given what we know, we can confirm that despite not being able to provide a visual representation, if you were to create one, it would show the atoms in the substance moving with <u>more and more </u>energy over time until vaporization occurred.

<h3>What is vaporization?</h3>

Vaporization is the changing of a liquid into a gas.
This is known as a phase change.
This happens when the atoms receive enough heat energy.
The heat energy provides the atoms with kinetic energy and causes them to move faster over time.
When the kinetic energy is enough to rupture the bonds that hold a liquid together, it becomes a gas.

Therefore, given that vaporization is when atoms within a substance gain so much kinetic energy that they are able to rupture the bonds that hold them relatively close together and change into a gas, we can confirm that a visual representation would have to be a diagram showing the increased movement of atoms over time.
