Answer:
C. The amount of product will be limited by the number of moles of
the limiting reagent.
Explanation:
a p e x :)) i just took the quiz
The amount of product will be limited by the number of moles of
the limiting reagent. Hence, option C is correct.
What is a Limiting reagent?The reactant that gets consumed early in the reaction restricts the quantity of product which will be produced in the chemical reaction. Thus, the reactant that gets consumed early in a chemical reaction is a limiting reagent.
Hence, the amount of product will be limited by the number of moles of the limiting reagent.

For the balanced equation shown below, how many moles of Al will react with 98.7 moles of CuSO4
Answer:
65.8 mol
Explanation:
Step 1: Write the balanced equation for the single displacement reaction
2 Al + 3 CuSO₄ → Al₂(SO₄)₃ + 3 Cu
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of Al to CuSO₄ is 2:3.
Step 3: Calculate the number of moles of Al that will react with 98.7 moles of CuSO₄
98.7 mol CuSO₄ × 2 mol Al/3 mol CuSO₄ = 65.8 mol Al

Answer:
160.000 años corresponde a 16.000 décadas.
Explanation:
Para resolver correctamente el ejercicio debemos plantear la regla de tres simple de la siguiente manera:
1 década equivale a 10 años; A cuantas decadas equivalen 160.000 años?
1 década→10 años
x ←160.000 años
Debemos multiplicar 160.000 por 1 y luego dividir entre 10 ;
x=([tex]\frac{160.000x1}{10}[/tex])=16.000 décadas; en notación científica sería 16x10^3.
Respuesta: 160.000 años corresponde a 16.000 décadas.
Complete the table with the mass number, number of protons, number of neutrons, and number of electrons for the elements shown.
Answer:
Explanation:
The Proton number for flourine will be 9
Then the mass number which will be protons+ neutrons will be 19
Argon which has a mass number of 40
to find the proton number of argon it will be 40-22=18
then the electron number will just be the same as proton number
then calcium the proton will be the same as electron so it will be 20
then neutrons will be mass number -proton number
which is 21

What are ions?
An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.
Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.Ions are generated on dissociation.

PLZ help me with this question
Answer:
Mean: 350
Median: 300
Range: 650
Mode: 300
Explanation:
Mean: 800+300+150+300+200= 1750, 1750 divided by 5 = 350
You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS to find the mean.
Median: (150, 200, 300, 300, 800)
To find Median put the numbers in order from greatest to least then you choose the middle number.
Range: Range is the distance from the smallest number to the largest the way to solve this is (Highest number) - (lowest number). In your case its 800-150 which equals 650
Mode: The mode is the value that appears most frequently in a data set.

how do I find the slope of this graph? Is it even possible?
Answer:
Not exactly But you can take the slope of the curved portion and the slope of the flatline.
It wont do you much good since your working for absorbance but if you ever see something like a temperature change you can use the slope(s) to find freezing points/melting
Explanation:
If you need to submit a slope you could use a best fit which is just point to point or you could break it up like i mentioned
How many moles are in 5.34 x 10*21 particles of Nitrogen?
Help plzzzzz it's due today ----- Would Shining light on the reaction increase or decrease the reaction rate
Answer:
increase
Explanation:
Reactions that are initiated by light are called photochemical reactions. The brighter the light, the faster the reaction.
Answer: An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. 17.5 “Temperature and Reaction Rate”).
Explanation:
Explain the difference between endothermic and exothermic processes. Provide an example of each.
These are reactions that transfer energy to the surroundings (ie the energy exits from the reaction, hence the name exothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become hotter. A thermometer is used to detect the temperature increase.
Examples:
Combustion
Neutralisation between acids and alkali
Endothermic reactionsThese are reactions that take in energy from the surroundings (ie energy enters the reaction, which will help you to remember the name endothermic). The energy is usually transferred as heat energy, causing the reaction mixture and its surroundings to become colder. A thermometer is used to detect the temperature decrease.

Ionic compounds form because ___ charges attract
Answer:
Ionic bonding is the attraction between positively- and negatively-charged ions. These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel.
Explanation:
Ionic compounds form because opposite charges attract.
In an ionic compound, positive and negative ions come together to form a stable structure. This occurs when an atom loses electrons to become a positively charged ion (cation) and another atom gains those electrons to become a negatively charged ion (anion). The positive and negative charges of the ions attract each other, resulting in the formation of an ionic bond.
This attraction between positive and negative charges is what holds ionic compounds together. The strong electrostatic forces of attraction between ions result in a lattice structure, where each ion is surrounded by oppositely charged ions.
Thus, ionic compounds are formed because opposite charges attract.

Hello,
After doing the Knewton assignments and watching some videos. I really do not understand some basics concepts of Energy. One of the questions is asking: Which of the following objects has more kinetic energy than does potential energy?
a) a compressed spring in a pinball machine just before the ball is launched.
b)a rollercoaster motionless at the top of the track.
c) a yo-yo before it is released
d)the pendulum of a grandfather clock at the lowest point of its arc of motion.
I thought that the answer was b, but the correct answer was c). I did not understand the explanation. It says " Kinetic energy is the energy of motion. Each of the objects above are motionless—with stored potential energy—except for the clock. At the bottom of its arc it will have the greatest kinetic energy, which is then converted to potential energy as it swings back up to one side"
So if someone could explain this better I would so good.

a certain kind of light has a wavelength of 4.6 micrometers what is the frequency of this light and gigahertz? Use c= 2.998 × 10^8 m/s for the speed of light.
Answer:
6.52×10⁴ GHz
Explanation:
From the question given above, the following data were obtained:
Wavelength (λ) = 4.6 μm
Velocity of light (v) = 2.998×10⁸ m/s
Frequency (f) =?
Next we shall convert 4.6 μm to metre (m). This can be obtained as follow:
1 μm = 1×10¯⁶ m
Therefore,
4.6 μm = 4.6 μm × 1×10¯⁶ m / 1 μm
4.6 μm = 4.6×10¯⁶ m
Next, we shall determine frequency of the light. This can be obtained as follow:
Wavelength (λ) = 4.6×10¯⁶ m
Velocity of light (v) = 2.998×10⁸ m/s
Frequency (f) =?
v = λf
2.998×10⁸ = 4.6×10¯⁶ × f
Divide both side by 4.6×10¯⁶
f = 2.998×10⁸ / 4.6×10¯⁶
f = 6.52×10¹³ Hz
Finally, we shall convert 6.52×10¹³ Hz to gigahertz. This can be obtained as follow:
1 Hz = 1×10¯⁹ GHz
Therefore,
6.52×10¹³ Hz = 6.52×10¹³ Hz × 1×10¯⁹ GHz / 1Hz
6.52×10¹³ Hz = 6.52×10⁴ GHz
Thus, the frequency of the light is 6.52×10⁴ GHz
