What are the different ways the simulation shows that the equation balances visually.

For every reaction that’s balanced, indicates the total number of molecules ( the large coefficients ) in the table.

The reaction number total of molecules

The reactive side ( left ) The product ( right )

Make Ammonium

Water separated

Combust(?) Methane

Is the number of molecules totals in the left side of a balanced equation, is always the same number of molecules that totals on the right side of the equation? Explain your answers.

For every balanced reaction, indicated the total number of atoms ( the individual atoms ) in the table. Suggestion: this can require multiplying that subscript for the coefficient of some of the atoms.

Example: 2NH3: There’s 2 atoms of N and 6 atoms of H ( 2 x 3 ).

The reaction number of the total of atoms.

The reactive side ( left ) The product side ( right )

Make Ammonium

Separate Water

Combust Methane

Does the number of the atoms total to the left side of a equation balanced is always the same number of atoms total in the right side of the equation?

What strategy did you used when you played the game of the chemical equation of the equivalent? What atoms were more easier to start examining to try to balance the equations? Did it require trial and error ?

In the simulation, could you use the numbers that didn’t enter ( like 1/2 or 0.43 ) for the coefficients of a balanced equation?

Decide whether each proposed multiplication or division of measurements is possible. If it is possible, write the result in the
Tju [1.3M]

The possible options for the proposed multiplication or division of measurements are:

1. 9.0 km * 7.0 km = 63 km²; this is a correct option because km² is dimensionally correct.

3. 24 dL²/0.60 L = 0.24 L²/0.60 L = 0.4 L is a correct option since L is a unit of volume.

<h3>What are the possible options among the proposed multiplication or division of measurements?</h3>

The possible options among the proposed multiplication or division of measurements are those which are dimensionally correct.

Considering the given options:

1. 9.0 km * 7.0 km = 63 km²

This is a correct option because km² is dimensionally correct as it is a unit of area.

2. 2.0 g²  * 0.043 kg is not correct since there is no unit of square mass.

3. 24 dL²/0.60 L = 0.24 L²/0.60 L = 0.4 L is a correct option since L is a unit of volume.

In conclusion, the correct measurements options are those that are dimensionally correct.

If a solution has a pOH of 8.71, what is the [H+]?
TEA [102]

Answer: 5.1\times 10^{-6}M

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration.

pH=-\log [H^+]

pH+pOH=14

Putting in the values:

pH=14-8.71=5.29

5.29=-log[H^+]

[H^+]=5.1\times 10^{-6}

Thus [H^+] is 5.1\times 10^{-6}M

If an object has a mass of 180 g and a density of 6 g/cm^3, what is the volume of the object?
cupoosta [38]

Answer:

<h3>The answer is 30 cm³</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 180 g

density = 6 g/cm³

We have

volume =  \frac{180}{6}  \\

We have the final answer as

<h3>30 cm³</h3>

Hope this helps you

Benzene can be nitrated with a mixture of nitric and sulfuric acids. How do we do that?
Montano1993 [528]

Answer:

We can do the nitration of benzene by treating the benzene with a mixture of nitric acid and sulphuric acid by not extending the temperature of 50°C

Explanation:

Nitration of benzene takes place by treating the benzene with a mixture of nitric acid and sulphuric acid at low temperatures such as the temperatures below 50°C

The nitration of benzene takes place through electrophilic substitution reaction

In this reaction the electrophile is nitronium ion (NO2+) which performs an electrophilic substitution reaction on the benzene ring and during the reaction an intermediate will also be formed in which there will be positive charge distributed in the benzene

These electrophile is generated when nitric acid is treated with sulphuric acid

As nitric acid is a strong oxidising agent, here in this case the oxidation state of nitrogen will change from +5 to +3

The reactions regarding the nitration of benzene is present in the file attached
