true or false, Electromagnetic radiation with a higher energy, travels with higher speed than electromagnetic radiation with a lower energy
Answer:
True.
Explanation:
Since electromagnetic radiation travels in waves, we can assume that the more high energy the waves are, the faster they will go. So therefore, higher energy travels faster.

You measure the absorbance of your extracted curcumin solution and realize that the solution is too concentrated. What made you realize this
If the absorbance of a solution of curcumin which is too concentrated is measured, the absorbance will be unusually high.
Spectrometry measures the interaction of light with molecules. The absorbance refers to how much light that interacts with molecules of the substance. The more the concentration of the substance the higher the absorbance of the solution.
Hence, if the absorbance of a solution of curcumin which is too concentrated is measured, the absorbance will be unusually high. An unusually high absorbance tells us that the solution is too concentrated.

A balloon with an initial volume of 3.1 L at a temperature of 193 K is warmed to 374 K.
What is its volume at the final temperature? (Assume constant temperature.)
Answer:
New volume = 6.0L
Explanation:
Make a list of variables given in the question, and what we want to find:
Initial volume (L) = Vi = 3.1
Initial temperature (K) = Ti = 193
New temperature (K) = Tn = 374
New volume (L) = Vn
We have volumes and temperatures given and we're talking about gas, the equation including both these variables that should come to mind is the ideal gas equation:
PV = nRT
P = pressure (Pa)
n = number of moles
R = gas constant = 8.31
Now, we construct an equation we can solve to get the new volume:
P(Vn) = nR(Tn)
And insert the values we know:
P(Vn) = n(8.31)(374)
P(Vn) = n·3107.94
The equation contains 3 unknown variables;
We should first try to see if we can eliminate the 2 we are not interested in, namely P and n;
What we should recognise is that the pressure and number of moles will not change upon warming the balloon;
Firstly, heating the gas inside the balloon doesn't add anything to the balloon, i.e. doesn't increase the moles of gas, it simply raises the energy of the gas particles already within the balloon, so n will not change;
Secondly, I think there is a mistake in the question, it should read "assume constant pressure" in the brackets, since the temperature does change, which we are told;
Also, we can assume normal atmospheric pressure inside and outside the balloon as would be the case ordinarily;
What we want to do with this information is rearrange the equation we constructed to have these 2 constant or unchanging variables on one side and everything else on the other, so:
[tex]\frac{P}{n} = \frac{3107.94}{V_{n} }[/tex]
Next, we construct an equation for the balloon before warming:
P(Vi) = nR(Ti)
P(3.1) = n(8.31)(193)
P·3.1 = n·1603.83
Once again, rearrange to get P and n on one side of the equation and everything else on the other:
[tex]\frac{P}{n} = \frac{1603.83}{3.1} \\\\ \frac{P}{n} = 517.364516[/tex]
Now, we have two equations for P/n, we can eliminate P/n since both these values remain the same before and after warming the balloon as previously established:
[tex]\frac{3107.94}{V_{n} } = \frac{P}{n} = 517.364516 \\\\ \frac{3107.94}{V_{n} } = 517.364516 \\\\[/tex]
Now, rearrange and solve for Vn:
[tex]\frac{3107.94}{V_{n} } = 517.364516 \\\\ V_{n} = \frac{3107.94}{517.364516} \\\\ V_{n} = 6.00725...[/tex]
Vn = 6.0L
A quantity of electricity equal to 9.439 x 104 C passes through a galvanic cell that has an Ni(s) anode. Compute the maximum chemical amount, in moles, of Ni2 (aq) that can be released into solution.
The maximum chemical amount in moles of Ni₂ (aq) that can be released into the solution is 0.978 mol.
Using Q = nF where Q = quantity of electricity = 9.439 × 10⁴ C = 94390, n = number of moles of NI₂ (aq) and F = Faraday's constant = 96485 C/mol
Making n subject of the formula, we have
n = Q/F
substituting the values of the variables into the equation, we have
n = Q/F
n = 94390 C/96485C/mol
n = 0.978 mol
So, the maximum chemical amount in moles of Ni₂ (aq) that can be released into the solution is 0.978 mol.

Since gas molecules average velocity depends on temperature, oxygen molecules at 25°C are moving faster than oxygen molecules at 0 °C.
According to the kinetic theory of gases, the molecules of a gas are in constant random motion and collide frequently with each other and the walls of the container.

My QUESTION
A car is travelling 35 miles per hour. How fast is it going when
measured in meters per minute?
Answer:
933.33 m/ min
Explanation:
1 mile = 1.6 km
So the car travels 1.6× 35 km in 1 hour
One hour has 60 minutes
So speed of car = 1.6×35 km / 60 minutes
1km = 1000 m
Speed = 1.6×35×1000 m/ 60 minutes
= 933.33 meters per minute
A car is traveling 35 miles per hour. The speed that is measured in meters per minute is 933.33 m/ min.
What is speed?Speed is the dimension of distance. It is calculated in meters per second. It is the rate of change of an object in a direction. Speed is calculated by dividing the distance by time. It is a scalar quantity.
Given, that a car is traveling 35 miles per hour. The speed is given, in miles we just have to convert the miles into meters per minute. Miles if the English unit of measurement and meter is the SI unit of measurement.
1 mile = 1.6 km
So the car travels 1.6× 35 km in 1 hour
One hour has 60 minutes
So speed of car = 1.6×35 km / 60 minutes
1km = 1000 m
Speed = 1.6 × 35 × 1000 m/ 60 minutes
= 933.33 meters per minute
Thus, the speed of the car is 933.33 m/ min.

Is there more than one possible model that could be inferred from Rutherford’s data?
Rutherford proposed the nuclear model of atom. The only one model which can be inferred from this model is nucleus with protons and revolving electrons around.
What is Rutherford model?Rutherford proposed some aspects of atomic structure based on his gold foil experiment. He discovered that the alpha ray is scattering from foil by the repulsion it experienced from the metal.
This results lead to the discovery of positively charged particles in atom latter called as protons. Rutherford proposed that theses protons are located inside the nucleus and the electrons are revolving around the nucleus.
Latter Niels Bohr his student interpreted the nuclear model of Rutherford with quantum mechanics and theory of max planck and he proposed the equations for the determination of energy and momentum of electrons and the radius of atom.
Therefore, no other inferences except the presence of protons and revolving electrons can be obtained from Rutherford's model of atom.
