Explanation:

It is known that Fe(OH)_{3} is insoluble in water. As a result, plants are not able to absorb Fe^{3+} readily through osmosis.

Therefore, the Fe^{3+} in Fe(OH)_{3} would be released in acidic environments, using neutralization, Iron(III) ions can be released.

Hence, the easiest way is to add low concentrations of H_{2}SO_{4} to the soil is as follows.

         Fe(OH)_{3} + H_{2}SO_{4} \rightarrow H_{2}O + Fe_{2}(SO_{4})_{3}

Thus, we can conclude that Fe_{2}(SO_{4})_{3} is soluble and is good for plants too.

If the actual yield of a reaction is 37.6 g while the theoretical yield is 112.8 g what is the percent yield
Zigmanuir [339]
<h2>Hello!</h2>

The answer is:

The percent yield of the reaction is 32.45%

<h2>Why?</h2>

To calculate the percent yield, we have to consider the theoretical yield and the actual yield. The theoretical yield as its name says is the yield expected, however, many times the difference between the theoretical yield and the actual yield is notorious.

We are given that:

ActualYield=37.6g\\TheoreticalYield=112.8g

Now, to calculate the percent yield, we need to divide the actual yield by the theoretical and multiply it by 100.

So, calculating we have:

PercentYield=\frac{ActualYield}{TheoreticalYield}*100\\\\PercentYield=\frac{37.6g}{112.8g}*100=0.3245*100=32.45(percent)

Hence, we have that the percent yield of the reaction is 32.45%.

Have a nice day!

What happened to the concentration of the product of H2O when the reaction shifts to the left
lilavasa [31]

I might need a diagram for this, but I have a vague idea of what you are talking about.

If H20 is going left it means the temperature is going lower.

The molecules will condense to slowly become ice

Water has a density of 1.0g/ml * Physical Property Physical Change Chemical Property Chemical Change
Daniel [21]

The density of water is a physical property.

You can measure it without changing the water to a different substance.

It is <em>not a physical change</em> because the water does not change to ice or steam.

You can observe a <em>chemical property</em> or a <em>chemical change</em> only if the water <em>changes to a different substance</em>.

When would it be useful for gas to form?
Alexus [3.1K]

Answer: A gas is a form of matter that lacks either a defined shape or a define volume. In other words, it fills a container and takes its shape. Any form of matter that exists as a solid or liquid also takes the form of a gas. Matter changes into a gas when temperature increases and pressure decreases.
