The process of photosynthesis is essential in the oxygen/carbon dioxide cycle. Photosynthesis removes from the atmosphere and produces and releases into the atmosphere.A) glucose, oxygen
B) oxygen, glucose
C) carbon dioxide, oxygen
D) oxygen, carbon dioxide

Answers

Answer 1

Answer:

The answer is C) carbon dioxide, oxygen.

Explanation:

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

So lets eliminate some answers:

Photosynthesis removes oxygen from the atmosphere and produces and releases glucose into the atmosphere.

Oxygen can not convert itself to glucose and plants don't take in oxygen so this answer is automatically eliminated

Photosynthesis removes oxygen from the atmosphere and produces and releases carbon dioxide into the atmosphere.

Plants take in carbon dioxide and convert it to oxygen basically how humans breath but inverted, not the other way around.

Photosynthesis removes glucose from the atmosphere and produces and releases oxygen into the atmosphere.

Glucose naturally is not found in the atmosphere in the first place so if a plant were to survive is would have to be in a glucose enriched environment which is very uncommon meaning it would be very rare to be a living functional plant that can photosynthesize. So this is checked off the list!

So we are now left with one sentence that would make sense

Photosynthesis removes carbon dioxide from the atmosphere and produces and releases oxygen into the atmosphere.

Plants take in carbon dioxide meaning the first section of this answer is right and they release oxygen which is also correct therefore this statement is valid and is the correct answer

Hope this helped (:

Select the sketches that show aqueous solutions of a strong and weak acid.

Answers

Answer:

The strong acid is that which undergoes the most amount of ionization into hydrogen ions in aqueous solution

Explanation:

Here we note that the strength of an acid is determined by the degree of ionization into hydrogen ions [H⁺] and hydoxonium ions an aqueous solution.

Therefore, the solution that has the highest proportion of hydrogen ions per each acid molecule is considered the stronger acid.

Final answer:

Strong acids ionize more completely in an aqueous solution and thus produce a higher concentration of hydronium ions. Conversely, weak acids only partially ionize, producing fewer hydronium ions.

Explanation:

An aqueous solution of a strong acid will show a higher concentration of hydronium ions (H3O+) as a result of more complete ionization. This is because, in a strong acid, nearly every molecule dissociates, yielding these ions.

Conversely, an aqueous solution of a weak acid will show a lower concentration of hydronium ions due to partial ionization. The molecules of a weak acid do not completely dissociate, resulting in fewer ions.

These behaviors are depicted in the given figures, which show the relative strengths of acids, differentiated based on their acid-ionization constants (Ka) and the concentration of hydronium ions they generate.

Which statement describes a chemical property of aluminum?(1) Aluminum is malleable.
(2) Aluminum reacts with sulfuric acid.
(3) Aluminum conducts an electric current.
(4) Aluminum has a density of 2.698 g/cm3 at STP.

Answers

The correct answer as to which statement describes a chemical property of aluminum would be that it reacts with sulfuric acid.

There are two properties of every substance - physical and chemical properties.

Physical properties refer to the characteristics that can be observed without altering the substance while chemical properties refer to the characteristics of undergoing chemical changes in reactions.

Physical properties include color, boiling and melting point, hardness etc., while chemical properties include reactivity, toxicity, flammability, etc.

All the options have to do with physical properties of aluminum except its reactivity with sulfuric acid. The equation of reaction is as follows:

Al + H2SO4 ---> Al2(SO4)3 + H2

Natural gas, or methane, is an important fuel. Combustion of one mole of methane releases 802.3 kilojoules of energy. How much energy does that represent in kilocalories?

Answers

Answer: 802.3 kilo Joules of energy represents 191.75 kilo Calorie of energy.

Explanation:

Energy released during combustion of one mole methane = 802.3 kilo Joules

If 1 kilo Joule = 0.239006 kilo Calorie

Then ,802.3 kilo joule will be = 802.3 $*$ 0.239006 kilo Calorie

802.3 kilo joule = 191.75 kilo Calorie

Hence, the energy in kilo Calorie is 191.75 kilo Calorie.

Answer:

191.7497 Kilocalories

Explanation:

Step 1:

Data obtained from the question:

Energy released = 802.3KJ

Step 2:

Conversion of the energy released in kilojoules to kilocalories. This is illustrated below:

1 KJ = 0.239 kilocalorie

Therefore, 802.3 KJ = 802.3 x 0.239 = 191.7497 Kilocalories

From the calculation above, 802.3 KJ is equivalent to 191.7497 Kilocalories

What needs to happen for a solute to dissolve in a particular solvent?

Answers

Answer: In order to a solute to dissolve in a solvent, both the attraction forces that bind the units of solute together and the intermolecular forces that bind the molecules of solvent together must be weaker than the attraction forces between the particles of solute and the molecules of solvent.

Explanation:

The solute particles in are binded together in virtue of attractive forces (the nature and strength of these forces depends on the particular solute).

The same happens with the solvent molecules: they are binded by attractive forces (similarly, the nature and strength of these forces depend on the particular solvent).

To get dissolved (form solution) the particles of solute must be separated and mixed with the solvent particles in a process called solvatation.

The solute particles must surrounded by the solvent particles.

When the forces of attraction between the solute particles and the solvent are stronger than the forces of attraction that bind the solute particles, the solute particles move away from the solid solute and are integrated into the solution.

the attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together.
