Apollo boasted to Cupid about how much larger his bow was. Apollo was offended, and Cupid hit him with a golden love arrow in retaliation, leading him to fall in love with the first person he saw.
What harm did Eros cause Apollo?Apollo had cracked far too many jokes about Eros. Eros shot Apollo with one of his golden arrows as a kind of retribution, which caused Apollo to fall hopelessly in love with the nymph Daphne.
Is Cupid able to vanquish Apollo?The next action taken by Cupid was something Apollo did not anticipate. The god of love flapped his wings as he soared alongside the god of music. Then, with a "golden arrow with a keen gleaming point," he shot him in the chest.

If 335 g water at 35.5C loses 5750 J of heat, what is the final temperature of the water?
Answer:
The final temperature is 39.58 degree Celsius
Explanation:
As we know
Q = m * c * change in temperature
Specific heat of water (c) = 4.2 joules per gram per Celsius degree
Substituting the given values we get -
5750 = 335 * 4.2 * (X - 35.5)
X = 39.58 degree Celsius

What is the new pressure if the temperature outside is 296k and his weight causes the tire's volume to drop to 2.0 liters
Question:
At standard temperature and pressure, the volume of a tire is 3.5L. What is the new pressure if the temperature outside is 296k and its weight causes the volume of the gas is 2.0 L?
Answer:
The new pressure is: 1.896 atm
Explanation:
At standard temperature and pressure, we have:
[tex]P_1 = 1atm[/tex]
[tex]T_1 = 273.15k[/tex]
[tex]V_1 = 3.5L[/tex]
Outside, we have:
[tex]T_2 = 296k[/tex]
[tex]V_2 = 2.0L[/tex]
Required
Determine the new pressure
Using combined gas law, we have:
[tex]\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}[/tex]
This gives:
[tex]\frac{1 * 3.5}{273.15} =\frac{P_2*2.0}{296}[/tex]
Solve for [tex]P_2[/tex]
[tex]P_2 = \frac{296 * 1 * 3.5}{273.15*2.0}[/tex]
[tex]P_2 = \frac{1036}{546.30}[/tex]
[tex]P_2 \approx 1.896 atm[/tex]

Explanation:
A study was conducted to see if increasing the substrate concentration has an appreciable effect on the velocity of a chemical reaction. With a substrate concentration of 1.5 moles per liter, the reaction was run 15 times, with an average velocity of 7.5 micromoles per 30 minutes and a standard deviation of 1.5. With a substrate concentration of 2.0 moles per liter, 12 runs were made, yielding an average velocity of 8.8 micromoles per 30 minutes and a sample standard deviation of 1.2. Is there any reason to believe that this increase in substrate concentration causes an increase in the mean velocity of the reaction of more than 0.5 micromole per 30 minutes
Answer:
There is not enough evidence
Explanation:
For 1.5 moles substrate concentration per liter
Reaction ( n2 ) = 15 runs
average velocity ( x2 ) = 7.5 micromoles per 30 minutes
standard deviation ( s2 ) = 1.5
For 2.0 moles substrate concentration per liter
Reaction( n1 ) = 12 runs
average velocity ( x1 ) = 8.8 micromoles per 30 minutes
standard deviation ( s1 ) = 1.2
Show Reason to believe that this increase in substrate conc causes an increase in mean velocity
Hypothesis test
H0 : μ1 - μ2 = 0.5
H1 : μ1 - μ2 > 0.5
level of significance ( ∝ ) = 0.01
attached below is a detailed solution to the problem
P-value ( 0.073 ) > level of significance ( 0.01 ) hence we fail to reject the null hypothesis
hence there in not enough evidence to believe that this increase causes an increase in the mean velocity of the reaction of more than 0.5 micromole per 30 minutes
How many grams of glycerine, C3H8O3, are needed to make 100. mL of 2.60 M solution?
Answer:
the mass of the glycerine needed in the given solution is 23.92 g
Explanation:
Given;
molarity of the solution (C₃H₈O₃), C = 2.60 M
Volume of the solution, V = 100 mL = 100 x 10⁻³ L = 0.1 M
The molarity of a solution is given as follows;
[tex]Molarity = \frac{amount \ of \ solute \ (moles)}{volume \ of \ solution \ (L)} \\\\amount \ of \ solute \ (moles) = Molarity \ \times volume \ of \ solution \ (L)\\\\amount \ of \ solute \ (moles) = 2.6 \times 0.1 \\\\amount \ of \ solute \ (moles) = 0.26 \ mole[/tex]
The molecular mass of the given solution;
molecular mass = (12 x 3) + (8 x 1) + (16 x 3)
molecular mass = 92 g/mol
The mass of the glycerine needed in the given solution is calculated as follows;
reacting mass = amount of solute (moles) x molecular mass (g/mol)
reacting mass = 0.26 x 92
reacting mass = 23.92 g
Therefore, the mass of the glycerine needed in the given solution is 23.92 g

Complete question:
A ball with a weight of 0.5 kg is sitting on a shelf that is 3 meters high. What is the gravitational potential energy of the ball ?
Help me! This is 8th grade sci btw
Answer:
the gravitational potential energy of the ball is is 14.7 J.
Explanation:
mass of the ball, m = 0.5 kg
height above the ground on which the ball is sitting, h = 3 m
The gravitational potential energy of the ball is calculated as follows;
P.E = mgh
P.E = 0.5 x 9.8 x 3
P.E = 14.7 J
Therefore, the gravitational potential energy of the ball is is 14.7 J.

Those microscopic organisms perform what 2 processes that help pave the way for lichen by creating organic material.
Answer:
Decomposition pf residues and weathering of rock.
Explanation:
Microorganisms performs two processes such as decomposition and weathering of rock materials. These two processes make the medium suitable for the growth and development of the lichens because these processes increases nutrient and organic matter on the rock surface that is used by the lichens for its growth. In decomposition process, larger compounds are broken down into simpler substances while on the other hand, the weather of rocks causes breakdown of rock material into simpler minerals that also used by the lichens.
There are moles of carbon present in 100 g of a
compound with the following percentage composition:
C= 40.0%, H = 6.72%, O = 53.29%.
Answer: 3.33
Explanation:
The molecular formula of the given composition is C₃H₆O₃.
What is molecular formula?Molecular formula is defined as a compound's chemical formula, which counts the total number of each element present in a molecule of the compound as discrete molecules. The arrangement of atoms in a molecule in three dimensions is known as molecular geometry, commonly referred to as the molecular structure.
The percentage composition is
C = 40.00 %
H = 6.72 %
O = 53.29 %
Mole = 100 g
Mass of C = 40 / 100 x 100 = 40 g
mass of H = 6.72 / 100 x 100 = 6.72 g
Mass of O = 53.29 / 100 x 100 = 53.29 g
Dividing the mass with moles
C = 40 / 12 = 3.3
H = 6.72 / 1 = 6.72
O = 53.29 / 16 = 3.3
Formula = C₃H₆O₃
Thus, the molecular formula of the given composition is C₃H₆O₃.

I NEED THIS LESS THAN 7 MINUTES IYS 15 POINTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! What is the difference between a balanced equation and an unbalanced equation?
All of the answers are correct.
A balanced equation obeys the law of conservation of mass, an unbalanced equation does not. An unbalanced equation shows the conservation of mass.
Balanced equations do not show equal numbers of atoms on each side of the equation.
Answer:
Balanced equation have equal number of atoms of different elements in the side of reactants and products.
Answer:
- A balanced chemical equation has an equal numbers of atoms of different elements in the side of reactants and products.
- An unbalanced chemical equation has an unequal number of atoms of one or more elements in the reaction.

How many grams of KCl are made when 5.02 moles of
ZnCl2 react in the reaction below?
2KMnO4 + ZnCl2 → 2KCl + Zn(MnO4)2
lol pls help me
Answer: 747.98 grams of KCl are made when 5.02 moles of [tex]ZnCl_2[/tex] react in the reaction.
Explanation:
The balanced chemical equation is:
[tex]2KMnO_4+ZnCl_2\rightarrow 2KCl+Zn(MnO_4)_2[/tex]
According to stoichiometry:
1 mole of [tex]ZnCl_2[/tex] produce = 2 moles of [tex]KCl[/tex]
Thus 5.02 moles [tex]ZnCl_2[/tex] will produce =[tex]\frac{2}{1}\times 5.02=10.04[/tex] moles of [tex]KCl[/tex]
Mass of [tex]KCl=moles\times {\text {molar mass}}=10.04mol\times 74.5g/mol=747.98g[/tex]
Thus 747.98 grams of KCl are made when 5.02 moles of [tex]ZnCl_2[/tex] react in the reaction.
