Answer:
This equation is not balanced because you don't have the same amount of each element on each side of the chemical reaction. The balanced equation is:
2 S + 3 ⇒ 2
The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.
Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts.
The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.
By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.
Then, taking into account all of the above, you can determine the amount of elements on each side of the equation:
Left side: 1 sulfur S and 6 oxygen O (coefficient 3 multiplied by sub-index 2)
Right side: 1 sulfur S and 3 oxygen O (subindice value)
As you can see, you have the same amount of sulfur on both sides of the equation but the amount of oxygen is different. This indicates that the chemical equation is not balanced. To balance it, as the amount of sulfur is the same, the amount of oxygen must be balanced, which is different on each side of the reaction.
A simple way is to balance the equation is to multiply the product by 2, that is, add a coefficient 2 in front of the SO3 molecule, the reaction being as follows:
S + 3 ⇒ 2
Now the amount of elements on each side of the equation is:
Left side: 1 sulfur S and 6 oxygen O (coefficient 3 multiplied by subindice 2)
Right side: 2 sulfur S and 6 oxygen O (coefficient 2 multiplied by subindice 3)
The oxygen is now balanced, but the amount of sulfur on both sides of the reaction varies. To balance the quantities of sulfur, as now on the right side you have an amount of 2, you can add the coefficient to sulfur. The chemical equation is as follows:
2 S + 3 ⇒ 2
Now the amount of elements on each side of the equation is:
Left side: 2 sulfur S and 6 oxygen O (coefficient 3 multiplied by subindice 2)
Right side: 2 sulfur S and 6 oxygen O (coefficient 2 multiplied by subindice 3)
Finally you have the same amount of sulfur and oxygen on both sides of the reaction. So the chemical equation is finally balanced.

Which statement about plant and animal cells is true? A. Plant cells have a nucleus and a cell wall; animal cells do not have either of these structures. B. Plant cells have a cell wall and chloroplasts; animal cells do not have either of these structures. C. Plant cells have a cell wall and a cell membrane; animal cells have a cell wall but not a cell membrane. D. Plant cells have chloroplasts and mitochondria; animal cells have chloroplasts but do not have mitochondria.
Answer:
B. Plant cells have a cell wall and chloroplasts; animal cells do not have either of these structures.
Explanation:
A major difference between a plant cell and an animal cell is presence of chloroplasts in plant cells. Another key difference between plant and animal cells is the presence of a cell wall in plant cells. Both structures are absent in an animal cells.
The cell wall surrounds the plasma membrane of plant cells. This helps to provide the required tensile strength and protection against mechanical and osmotic stress.
Cell walls also help plants to maintain shape and rigidity.
The plant cell has a cell wall and chloroplast, while the animal cell lacks both of them. Thus, option B is correct.
The cell has been the smallest unit of life that has been performing varying functions with the help of different organelles.
The plant cell has been exposed to harsh environmental conditions, thus has been consisting of the cell wall along with the cell membrane. However, animal cell lacks a cell wall.
The food has been processed in the plant cells with the help of photosynthesis that required chlorophyll. The chlorophyll has been consisted in the chloroplast. Thus plants cell have consisted of chloroplast, however, animal cells lack chlorophyll as well as chloroplasts.
Thus, the plant cell has a cell wall and chloroplast, while the animal cell lacks both of them. Thus, option B is correct.

How many moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas?
Balanced equation: 2H2 + O2 → 2H2O (5 points)
a. 2 moles of water
b. 4 moles of water
c. 5 moles of water
d. 7 moles of water
Answer:
It is b
Explanation: I did it on the test and got it right
The moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas - b. 4 moles of water
The stoichiometric coefficients can be considered in a balanced equation as moles of reactants needed or moles of products formed in the reaction.
In the given case, the balanced chemical equation for this synthesis reaction looks like this2H2 + O2 → 2H2O
from the balanced equation, it is clear that the 2 moles of hydrogen gas and 1 mole of oxygen gas are required to produce 2 moles of water. so it means that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction and the same moles as hydrogen atoms present.Here it is given that there are only 2 moles of oxygen which means it is in deficiency however, it will produce 4 moles of water with four moles of hydrogen.Thus, the moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas - b. 4 moles of water

Answer:
1.) 12 tablespoons of sugar and 3 cups of water (48 tablespoons)
2.) Amount of lemon juice, sugar and water required will be = 0.375 cups, 0.75 cups and 3 cups.
Step-by-step explanation:
Malanie is making lemonade and finds a recipe that requires lemon juice, sugar and water in the ratio of 1 : 2 : 8.
She juices 2 lemons to obtain 6 tablespoons of lemon juice.
∵ 16 tablespoons = 1 cup
∴ 1 tablespoon = cup
∴ 6 tablespoon = cup = 0.375 cups
Since ratio between lemon and sugar is 1 : 2
So amount of sugar required = 0.375×2 = 0.75 cups
Ratio between lemon and water is 1 : 8
So amount of water required = 0.375×8 = 3 cups
Therefore, amount of lemon juice, sugar and water required = 0.375 cups, 0.75 cups sugar and 3 cups respectively.

the reaction. One answer is below.
CH, + 0 = CO,
This equation is incorrect.
A. Explain how and why it is incorrect
B. What would the correct equation be, and how do you know that?
Answer:
The laboratory demonstration consists of the following;
The compounds present in the combustion reaction = Methane, CH₄ and Oxygen, O₂
The chemical equation for the combustion reaction is given as follows;
CH₄ + 2O₂ → CO₂ + 2H₂O
Therefore;
A. The equation given as CH₄ + O → CO₂ is not correct because;
1) Oxygen gas exist as diatomic molecules, O₂, and given that the experiment involves the mixture of gases, the oxygen gas present which can exist as a separate compound, should be represented as O₂
2) The number of oxygen molecules in the reaction is two rather than one
3) The product also includes two molecules of water (vapor) H₂O
B. The correct equation for the reaction should be given as follows;
CH₄ + 2O₂ → CO₂ + 2H₂O
B i) The constituents of the equation is obtained by the knowledge of the fact that the combustion reaction of an organic substance such as methane in the presence of oxygen yields, carbon dioxide and water (vapor)
The equation showing the relative amounts the reacting compounds is by balancing the basic equation of the combustion of methane in the presence of oxygen

LiCl: 42.39g/mol
Answer:Mole Fraction of NaCl=0.5697
Explanation:
No OF Moles of NaCl= Mass / Molar mass
=21.7 g/58.44g/mol
=0.371moles
No OF Moles of KCl= Mass / Molar mass
=3.74g/74.55g/mol
=0.0502moles

0.371/0.6512
=0.5697
Answer:
Mole fraction: 0.570
Explanation:
Mole fraction is defined as the ratio of moles of a compound in a mixture over the total moles of the mixture. To solve this problem, we need to find moles of the 3 salts:
Moles NaCl -Molar mass: 58.44g/mol-:
21.7g NaCl * (1mol / 58.44g) = 0.3713 moles
Moles KCl -Molar mass: 74.55g/mol-:
3.74g KCl * (1mol / 74.55g) = 0.0502 moles
Moles LiCl -Molar mass: 42.394g/mol-:
9.76g LiCl * (1mol / 42.394g) = 0.2302 moles
Mole fraction NaCl:
0.3713mol / (0.3713mol + 0.0502mol + 0.2302mol) =
0.570
