Answer:

Photosynthesis reaction is irreversible and so it is a chemical change.

<h2> </h2><h2>Explanation</h2>

<em>The plants produce their own food by using the carbon dioxide, water, chlorophyll which is a green pigment present in the leaves and sunlight. Here plants are converting light energy into chemical energy and here carbon dioxide and water is converted into glucose and oxygen and the reaction is irreversible and we cannot the reactants back and so photosynthesis is a chemical change.</em>

Reaction for this is given as - $6CO_{2} + 6H_{2}O ---> C_{6}H_{12}O_{6} +6O_{2}$

The products of the photosynthesis are not reversible and they are irreversible.

Consider the reaction: 2HI(g) ⇄ H2(g) + I2(g). It is found that, when equilibrium is reached at a certain temperature, HI is 35.

Answer:

Kc = 0.075

Explanation:

The dissociation (α) is the initial quantity that ionized divided by the total dissolved. So, let's calling x the ionized quantity, and M the initial one:

α = x/M

x = M*α

x = 0.354M

For the stoichiometry of the reaction (2:1:1), the concentration of H₂ and I₂ must be half of the acid. So the equilibrium table must be:

2HI(g) ⇄ H₂(g) + I₂(g)

M 0 0 <em> Initial</em>

-0.354M +0.177M +0.177M <em>Reacts</em>

0.646M 0.177M 0.177M <em>Equilibrium</em>

The equilibrium constant Kc is the multiplication of the products' concentrations (elevated by their coefficients) divided by the multiplication of the reactants' concentrations (elevated by their coefficients):

$Kc = \frac{[H2]*[I2]}{[HI]^2}$

$Kc = \frac{0.177M*0.177M}{(0.646M)^2}$

$Kc = \frac{0.03133M^2}{0.41732M^2}$

Kc = 0.075

You have a sample of 75.6 g of C3H8. How many moles of C3H8 are in the sample?

dsp73

The number of moles that are contained in the given mass of propane ( $C_3H_8$ is 1.7143 moles.

<u>Given the following data:</u>

Mass of propane = 75.6 grams.

<u>Scientific data:</u>

The molar mass of propane = 44.1 g/mol.

To calculate the number of moles that are contained in the given mass of propane ( $C_3H_8$ ):

<h3>How to calculate the moles of a compound.</h3>

In this exercise, you're required to determine the number of moles of propane that are contained in the given sample:

Mathematically, the number of moles contained in a chemical compound is given by this formula:

$Number\;of\;moles = \frac{mass}{molar\;mass}$

Substituting the given parameters into the formula, we have;

$Number\;of\;moles = \frac{75.6}{44.1}$

Number of moles = 1.7143 moles.

If scientists had tried to repeat thomosons experiment and found that they could not would thomosons cocnclusion still have been

lesantik [10]

Answer:

Explanation:

The conclusions from Thomoson's claims would be invalid if his experiment could not be replicated.

<em>One of the attributes of a valid experiment in science is replication. That is, an experiment must be repeatable with similar outcomes under similar conditions as the original experiment when independently performed by another scientist. Once an experiment cannot be replicated, the outcomes of such an experiment become invalid in science.</em>

Hence, <u>Thomoson's conclusion would be invalid if his experiment could not be replicated. </u>
