Answer:
No
Explanation:
In order for glucose to be produced inside the mixture, photosynthesis has to take place. The photosynthetic process requires a series of steps within an organelle called the chloroplast. The chloroplast contains the chlorophyll and other enzymes that are necessary for photosynthesis.
Once the chlorophyll is isolated, it becomes separated from the enzymes necessary for the completion of photosynthesis, and the process is truncated. When light is shined on the mixture, the majority would instead be lost as heat while some cause the chlorophyll molecules to glow.
Which of these are matter?

The atoms and molecules are matter. Therefore, option A and B are correct.
What is matter ?Matter is defined as anything that occupies space and has mass—in other words, the "stuff" of the universe. All matter is composed of substances known as elements, which have distinct chemical and physical properties and cannot be broken down into other substances via ordinary chemical reactions.
Matter is defined as anything that occupies space and has mass. Water and air are examples of matter, whereas feelings and sound are not.
Physical and chemical properties can be used to classify matter. Matter is defined as something that occupies space and has mass. Solid, liquid, and gaseous are the three states of matter. The conversion of a material from one state of matter to another without changing its chemical composition is referred to as a physical transition.
Thus, option A and B are correct.

Which orbital notation represents the second principal energy level of a silicon atom in the ground state?
Answer:
2
Explanation:
Silicon is one the elements found in nature and well positioned the periodic table.
It has an atomic number of 14 with an electronic configuration:
1s² 2s² 2p⁶ 3s² 3p⁴
From this formula the orbital notation that represents the second principal energy level is 2.
The main energy level in which the orbital is located or the average distance of the orbital from the nucleus is the principal quantum number.

The initial rate of formation of CO2(e) from the chemical reaction represented by the
equation above was studied in two separate experiments. The table above provides the
experimental conditions used. If both experiments are carried out with finely powdered
samples of the solid and 50.0mL of HCl(aq), which experiment, if any, will have the faster
initial rate of formation of CO2(g) and why?
The rate of formation of CO2(g) will be the same because the mass of CaCO3(s) and the volume of
HCl(aq) used will be the same in both experiments.
CO2(g) will be formed at a faster rate in experiment 2 because more H* particles can react per
unit time.
O CO26) will be formed at a faster rate in experiment 1 because the proportion of CaCO3(s)
particles to H* particles will be greater.
The rate of formation of CO2(e) will be the same because the surface area of the solid and the
average kinetic energy of the particles will be the same in both experiments.
Answer:CO2(g) will be formed at a faster rate in experiment 2 because more H+ particles can react per unit time
Explanation:
[tex]CO_2_{(g)}[/tex] will be formed at a faster rate in experiment 2 because more H+ particles can react per unit time. The correct option is C.
What is a chemical reaction?A chemical reaction is a process that transforms one or more substances, known as reactants, to one or more different substances, known as products. Chemical elements or compounds are examples of substances.

What is the molarity of a solution in which 0.321 g of calcium chloride is dissolved in 1.45 L water?
Answer:
Molarity = 0.002 M
Explanation:
Given data:
Mass of calcium chloride = 0.321 g
Volume of water = 1.45 L
Molarity of solution = ?
Solution:
Molarity = number of moles / volume in litter.
We will calculate the number of moles of calcium chloride first.
Number of moles = mass/molar mass
Number of moles = 0.321 g/ 110.98 g/mol
Number of moles = 0.003 mol
Molarity:
Molarity = 0.003 mol / 1.45 L

They are metals.
They have a charge.
They are made of two or more types of atoms.
They form chemical bonds through electron sharing.
Answer:
D. They form chemical bonds through electron sharing.
Explanation:
The correct characteristic of all ions is that they have a charge. Therefore option B is correct.
An ion is an atom or a molecule that has gained or lost electrons, resulting in an unequal number of protons and electrons. This imbalance of positive and negative charges gives the ion a net electrical charge.
Ions can have a positive charge (called cations) if they have lost electrons, or a negative charge (called anions) if they have gained electrons.
The charge of an ion is essential in determining its behavior and interactions with other ions and molecules. It influences the way ions form chemical bonds and participates in chemical reactions.
The charge of an ion is indicated by a superscript after the chemical symbol, such as Na+ for a sodium cation or Cl- for a chloride anion.

How many moles are equal to 89.23g of aluminum chloride, AlCl3?
Answer:
[tex]\boxed {\boxed {\sf 0.6692 \ mol \ AlCl_3}}[/tex]
Explanation:
To convert from grams to moles, we must use the molar mass. This can be calculated using the Periodic Table.
1. Molar Mass
First, identify the elements in the compound AlCl₃. They are aluminum and chlorine. Now find the masses:
Al: 26.981538 g/mol Cl: 35.45 g/molTake a look at the compound. There is a subscript of 3 after chlorine, so we must multiply its molar mass by 3 then add aluminum's.
AlCl₃= 3(35.34 g/mol) + 26.981538 g/mol = 133.331538 g/mol2. Convert Grams to Moles
We can use the molar mass as a ratio.
[tex]\frac{133.331538 \ g \ AlCl_3}{1 \ mol \ AlCl_3}[/tex]
Multiply by the given number of grams: 89.23
[tex]89.23 \ g \ AlCl_3 * \frac{133.331538 \ g \ AlCl_3}{1 \ mol \ AlCl_3}[/tex]
Flip the fraction so the grams of aluminum chloride cancel out.
[tex]89.23 \ g \ AlCl_3 * \frac{1 \ mol \ AlCl_3}{133.331538 \ g \ AlCl_3} = 89.23 \ * \frac{1 \ mol \ AlCl_3}{133.331538}[/tex]
[tex]\frac{89.23 \ mol \ AlCl_3}{133.331538}[/tex]
[tex]0.6692340112 \ mol \ AlCl_3[/tex]
3. Round
The original measurement of grams has 4 significant figures. We must round to 4 sig figs.
For the number we calculated, that is the ten thousandth place.
The 3 in the hundred thousandth place tells us to leave the 2.

There are about 0.6692 moles of aluminum chloride in 89.23 grams.

A balloon is inflated to a volume of 1.25L .If the temperature of the air inside is cooled from 35°C to 15°C , what will be the final volume of the balloon?
Answer:
V₂ = 1.17 L
Explanation:
Given data:
Initial volume of balloon = 1.25 L
Initial temperature = 35°C
Final temperature = 15°C
Final volume = ?
Solution:
Initial temperature = 35°C (35+273.15K = 308.15 K)
Final temperature = 15°C (15+273.15 K = 288.15 K)
The given problem will be solve through the Charles Law.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 1.25 L × 288.15 K / 308.15 k
V₂ = 360.2 L.K / 308.15 k
V₂ = 1.17 L

A
endocytosis.
B
diffusion.
C
active transport.
D
exocytosis.
Answer:
A endocytosis
Explanation:
The process by which a cell takes in a large particle is called endocytosis. Therefore, the correct option is option A.
What is endocytosis?Endocytosis is the procedure by which molecules are actively transported into the cell by being engulfed by its membrane. All cells use endocytosis and exocytosis to transport substances that cannot passively cross the membrane. Exocytosis serves the opposite purpose by ejecting molecules from the cell.
The requirement for homeostasis ensures an equal flow all molecules into and out of a cell, like all of the body's systems. This indicates that the number of molecules exocytosis and endocytosis both equal the number of molecules into the cell. The two systems work together to maintain a balance between nutrients and waste that is necessary for normal cell growth and function. The process by which a cell takes in a large particle is called endocytosis.
Therefore, the correct option is option A.
