Answer:

  • <u><em>It shifts left</em></u>

Explanation:

The<em> equilibrium</em> equation is:

  • Water + Energy ⇄ Vapor

By LeChatelier's principle when a <em>system</em> in <em>equilibrium</em> is disturbed, the system will react to counteract the disturbance and restore fhe equiibrium.

When one of the substances increases, look at where it appears in the chemical equilibrium equation and determine how that increase can be compensated.

In this case, the system will try to balance the increase in vapor, which is on the right side of the equation, by consuming part of it and producing more water and energy through the reverse reaction, from right to left. Thus, the system will shift left.

How many moles of gas would you have if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature
seraphim [82]

Answer: There are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

Explanation:

Given: Volume = 38.0 L

Pressure = 1430 mm Hg (1 mm Hg = 0.00131579 atm) = 1.9 atm

Temperature = 273.15 K

Using ideal gas equation, the moles of gas will be calculated as follows.

PV = nRT\\

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T =temperature

Substitute the values into above formula as follows.

PV = nRT\\1.9 atm \times 38.0 L = n \times 0.0821 L atm/mol K \times 273.15 K\\n = \frac{1.9 atm \times 38.0 L}{0.0821 L atm/mol K \times 273.15 K}\\= 3.2 mol

Thus, we can conclude that there are 3.2 moles of gas if you have a volume of 38.0 L under a pressure of 1430 mmHg at standard temperature.

From the addition of water to the molecule of an alkene is obtained a product containing 21.6% O2. Write the addition reaction.
klemol [59]

Addition reaction between water molecules and alkene molecules produces alcohol.

<h3>What is addition reaction?</h3>

Addition reaction generally takes place across the unsaturated carbon compounds.

When water molecule (H₂O) is added to the alkene which may be ethene (C₂H₄) molecule then formation of product i.e. ethanol (CH₃CH₂OH) takes place through the addition of hydrogen and hydroxyl group across the double bond. And reaction is shown in the attached image.

Hence formation of alcohol product takes place.

The concentration of an additive in a standard sample of palm oil was measured 6 times and the following results were obtained:
Lerok [7]

In the data, 0.20 ppm is an outlier and this can be rejected if there is a 95% confidence level.

<h3>What is an outlier?</h3>

When analyzing data an outlier is a value that is abnormal or too different from other data. In the case presented 0.20 can be tagged as an outlier because other values such as 0.11, 0.12, 0.13, and 0.14 are similar while 0.20 is outside this range.

<h3>Should this piece of data be rejected?</h3>

The general rule is that if there is a 95% of confidence or higher you can reject an outlier, knowing the other data occurs 95% of the time, and therefore the outlier is improbable.

Based on this, you can reject an outlier if the confidence level is 95%.
