At what temperature would the volume of a gas be equal to 45.7 L, if the volume of that gas was 33.9 L at 12.4ºC? 241.9 K 241.9 K 451.2 K 451.2 K 384.7 K 384.7 K 273.15 K
Answer:
The temperature will be 384.7 K
Explanation:
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules. .
In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
[tex]\frac{V}{T} =k[/tex]
Having an initial state 1 and a final state 2, the following is true:
[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]
In this case:
V1= 33.9 LT1= 12.4 C= 285.4 K (being 0 C= 273 K)V2= 45.7 LT2= ?Replacing:
[tex]\frac{33.9 L}{285.4 K} =\frac{45.7 L}{T2}[/tex]
Solving:
[tex]T2=45.7 L*\frac{285.4 K}{33.9 L}[/tex]
T2= 384.7 K
The temperature will be 384.7 K

Please can someone explain the differences in variables (e.g. control variable, Independent variable and Dependent variable). I know the definition, but I'm still not sure which is which when undertaking an experiment. Could someone possibly give me an example of an experiment and which is which?
Answer:
Independent Variable: The thing in an experiment which is changed.
Dependent Variable: The thing in an experiment which is affected by the change. (In other words, it's affected by the independent variable.)
Control Variable: The other factors of the experiment that remain unchanged.
For example, say you want to do an experiment about the effects of water on plant height. So, the independent variable, or the thing that is changed would be the amount of water, and the dependent variable would be the plant height, as the plant height is directly affected by the independent variable. Lastly, for this to be a fair experiment, there must be control variables. For example, all of the plants should be put in a room with equal temperature, they should get the same amount of sunlight, etc.
I hope this answers your question- feel free to ask me if you need any more help.
Answer with Explanation:
Lol.. even i was confused before .. so i learnt now ill help u :
Simple!
See... lets take simple expirament to explain:
My expirament is to verify if sunlight affects the growth of plants ...
So here :
My controlled variable : It is what is held constant.. So ur supposed to NOT it like everything else expect sunlight..(ex: water, soil, type of plant etc)
My Independent variable : Variable that is changed.... So this is wht u ARE changing to make th expirament ... (for ex: here sunlight u will chanhe... u will put on in a dark room and a nother in the light..)
My dependetn variabe:l Some thing that changes on is own..cause of the expiramen t... like the result ..(for ex: height , growth of plant etc)
I hope u understood !! :))

Why wasn't the water pasteurized? I chose Claim 1: If you follow the instructions, the POW kits will always heat the water above the correct temperature for pasteurization (65°C), but some people didn't follow the instructions Can someone help me support it?
Answer:
Claim 1- The evidence that supports my claim because Evidence Card b says “One man got sick, but his two children did not. He used water from Whip River. He used the cube to heat the first pitcher of water, which he gave to his kids, and then reused the cube without reheating for the second pitcher, which he drank himself.” My first piece of evidence is that if you don't follow thee directions then something bad would happen

Chlorine has 7 valence electrons. With what group of elements will chlorine most readily bond?
Group 1
Group 2
Group 16
Group 18
Answer:
group 1
Explanation:
chlorine donate electron
Chlorine will more likely to form bonds with the elements of group 1 as it has 7 valence electrons.
Chlorine element:Chlorine is an element that is present in group 17. This family is also known as the Halogen family. The elements of this group will have seven electrons in their outermost shell. It has only one electron less to attain a stable noble electron configuration.
Thus, it will form bond more readily with Group 1 that has only one electron in its outermost shell.
Thus, correct option is a.

How many grams of silver chromate are produced when 250. mL of 1.500 M Na2CrO4 are added to excess silver nitrate? Please balance the equation before solving the problem.
AgNO3(aq)+Na2CrO4(aq) --> Ag2CrO4(s)+NaNO3(aq)
30 points here!:)
Write the balanced chemical equation
Calculate the moles of
Na2CrO4
Use the molar ratio from the balanced equation to calculate the moles of
Ag2CrO4
Calculate the mass of
Ag2CrO4
mass of Ag2CrO4 produced is 124 g.
The mass of silver chromate are produced when 250. mL of 1.500 M Na₂CrO₄ are added to excess silver nitrate is 62.028g.
How do we calculate mass from moles?Mass of any susbtance will be calculated by using moles as:
n = W/M, where
W = given mass
M = molar mass
Relation between moles and molarity as:
M = n/V, where
M = molarity
V = volume
Moles of Na₂CrO₄ = (1.5)(0.25) = 0.375 mol
Given balanced chemical reaction is:
2AgNO₃(aq) + Na₂CrO₄(aq) → Ag₂CrO₄(s) + 2NaNO₃(aq)
From the stoichiometry of the reaction it is clear that,
2 moles of Na₂CrO₄ = produces 1 mole of Ag₂CrO₄
0.375 moles of Na₂CrO₄ = produces 1/2×0.375=0.187 mole of Ag₂CrO₄
Mass of 0.187 moles of Ag₂CrO₄ = (0.187mol)(331.7g/mol) = 62.028g
Hence required mass of Ag₂CrO₄ is 62.028g.

Around what pH are most of the substances in your body? Why?
Answer:
The pH scale measures how acidic or alkaline — basic — something is. Your body works constantly to carefully control pH levels of blood and other fluids. The body's pH balance is also called the acid-base or acid-alkaline balance. The right pH levels are needed for good health.
