<span>The product would be :
H3O+ Benzaldehyde -----> C6H5CHO.
It will form a neutral molecule. So the charge is neutral.
I hope it helped.</span>

2KClO3(s) =&gt; 2KCl(s) + 3O2(g) <br> is there an increase or decrease of entropy?
ValentinkaMS [17]

Answer:

Entropy increases

Explanation:

Entropy (S) is a measure of the degree of disorder.  For a given substance - say water - across phases the following is true ...

S(ice) < S(water) << S(steam)

For a chemical process, entropy changes can be related to increasing or decreasing molar volumes of gas from reactant side of equation to product side of equation. That is ...

if molar volumes of gas increase, then entropy increases, and

if molar volumes of gas decrease, then entropy decreases.

For the reaction                  2KClO₃(s) => 2KCl(s) + 3O₂(g)

molar volumes of gas =>       0Vm*            0Vm      3Vm

*molar volumes (Vm) apply only to gas phase substances. Solids and liquids do not have molar volume.

Since the reaction produces 3 molar volumes of O₂(g) product vs 0 molar volumes of reactant, then the reaction is showing an increase in molar volumes of gas phase substances and its entropy is therefore increasing.

Systematic or Random Error? -This type of error affects overall accuracy but does not necessarily affect precision. This type of
love history [14]

Answer:

<em>This type of error affects overall accuracy but does not necessarily affect precision.</em> - Systematic error

<em>This type of error affects precision but does not necessarily affect overall accuracy.</em> - Random error

<em>This type of error occurs if you use a buret that was calibrated incorrectly when it was made.</em> - Systematic error

<em>You can minimize this type of error by taking repeated measurements.</em> - Random error

Explanation:

<em>Systematic errors are errors that are attributable to instrument being used during measurement or consistent incorrect measurement during a research</em>. They are consistently and repeatedly committed during measurements and therefore affect the overall accuracy of measurements. A person committing systematic error can have precise repeated measurement but will be far from being accurate.

R<em>andom errors on the other hand has no pattern and are usually unavoidable because they cannot be predicted.</em> When sufficient replicate measurements are made, such errors are reduced to the barest minimum and usually do not affect the overall accuracy of measurements.

PLEASE!! *MEASURING MATTER VOCAB MATCHING*
Airida [17]
Matter - anything with mass and occupies space
accuracy - an indication of how close a measurement is to the correct result
precision - the degree to which a measurement can be replicated
meniscus - the curved top surface of a liquid column
volume - spaced occupied measured in cubic units
density - mass of an object per unit volume

Based on your knowledge of energy resources conservation, which of the following statements is true? a) Manufacturers can increa
Kruka [31]

Answer: Option (b) is the correct answer.

Explanation:

When useful energy is conserved then this conservation is known as energy conservation.

For example, when lights of a room are switched on where no one is sitting then on switching off the lights we are conserving wastage of electricity.

Thus, we can conclude that out of the given options, the statement energy resources can be conserved by turning off lights when they are not in use is true.

lead sulfide reacts with oxygen gas to produce lead oxide and sulfur dioxide. if 0.500 moles of o2 were consumed using this chem
Digiron [165]
Easy!

All you have to do is look at the formula.

Lead Sulfide is PbS

Lead Oxide is PbO

Sulfur Dioxide is SO₂

Oxygen is O₂

You would need to balance out the equation, so it would be PbS + O₂ --> PbO + SO₂.

We can balance this out with the following.  2PbS + 2O₂ --> 2PbO + SO₂.

So 0.500 moles of oxygen would be the same conversion rate for PbO so it would also be 0.500 moles of lead oxide (PbO)
