reaction. Which word could be used to describe UV light in this situation?
O A. Catalyst
B. Enzyme
C. Solvent
D. Reactant
Answers
because it is and it’s cool
The correct option for the given question about Harmfull effect of UV light is Option D) Reactant.
Why UV light is so harmfull for some vitamins?In general, temperature, oxygen, and light impacts on vitamins and minerals are sensitive. A nutrient can lose its biological potency if its molecular structure is slightly altered.Numerous vitamins, including vitamin A, vitamin B2 (riboflavin), vitamin B6, vitamin B12, and folic acid, are known to be particularly susceptible to UV radiation oxidation.Additionally, light speeds up the negative interactions between vitamins.For instance, the combination of riboflavin and light together speeds up the breakdown of both folic acid and vitamin C. This is what causes milk that has been exposed to light to lose vitamin C.Thus to conclude we can say that UV light damages some vitamins by reacting with them.

What is the pH of a solution that has [H+] of .0042M?
Answers
Answer:
pH = 2.4
Explanation:
pH is defined as the negative log of the hydronium concentration.
Thus, we can plug in the given hydronium concentration:
pH = -log[H⁺] = -log[0.0042] = 2.4 (two significant figures)
The pH of the solution is 2.4.
P.S: Although I referred to [H⁺] as hydronium concentration, it is more accurate to express it as [H₃O⁺], though they are interchangeable and means the same thing.

Plates on Earth are moving quickly. Yet, friction causes them to travel more slowly. So, the correct options are B and C.
What are tectonic plates?Tectonic plates are enormous fragments of the upper mantle and crust of the Earth. They are composed of both continental and oceanic crust. Earthquakes occur around mid-ocean ridges and the large faults which mark the edges of the plates.
The Earth's plates are shifting swiftly. Nevertheless, friction slows their movement. Gravity causes the floating plates to rise and fall. On occasion, the movement of tectonic plates results in earthquakes.
When compared to the Earth's mantle, the plates behave like solid, unyielding shells. The lithosphere is the name given to this thick outer layer.
Thus, the correct options are B and C.

If the hydroxide ion concentration of a solution is 3.26 x 10-6 M, is it an acidic or a basic solution?
Answers
Answer: It is a basic solution with pH =8.51
Explanation:
We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M
But We know thar
[OH-] [H+] = 1 × 10^-14
To get the Hydrogen ion [H+] concentration, we have that
[H+] = 1 × 10^-14 M/[OH-]
= 1 × 10^-14 M/3.26 x 10-6 M
= 3.067 x 10^-9 M
But, pH = - log [H+]
Therefore,
pH = - log (3.067 x 10^-9)
pH=8.51
when pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.

I have 130 L of gas in a piston at a temperature of 250°C. If I cool the gas
until the volume decreases to 85 L, what will the temperature of the gas be?
Answers
This is a Charles' Law problem: V1/T1 = V2/T2. As the temperature of a fixed mass of gas decreases at a constant pressure, the volume of the gas should also decrease proportionally. Here, we are given the new volume of the gas after cooling, and we want to determine to what temperature the gas was cooled.
To use Charles' Law, the temperature must be in Kelvin (x °C = x + 273.15 K). We want to solve Charles' Law for T2, which we can obtain by rearranging the equation into T2 = V2T1/V1. Given V1 = 130 L, T1 = 250 °C (523.15 K), and V2 = 85 L:
T2 = (85 L)(523.15 K)/(130 L) = 342 K or 68.9 °C. If sig figs are to be considered, since all the values in the question are given to two sig figs, the answer to two sig figs would be either 340 K or 69 °C.
Gases show great uniformity in their behaviour irrespective of their nature. The concept Charles's law is used here to determine the new temperature of the gas. The new temperature of the gas is 341.96 K.
What is Charles's law?At constant pressure, the volume of a given mass of gas is directly proportional to the temperature on Kelvin scale. The absolute scale of temperature is introduced by the scientist Charles. The temperature at which gases supposed to have zero volume is called the absolute temperature.
Mathematically the Charles's law can be expressed as:
V = constant × T
V / T = constant
For two different gases, the equation is:
V₁ / T₁ = V₂ / T₂
T₂ = V₂T₁ / V₁
85 × 523 / 130 = 341.96 K
Thus the new temperature of the gas is 341.96 K.

80 grams of water releases 2550 joules of heat. What is the temperature change of the water? Heat capacity of water is 4.2 J/g°C.
Answers
Answer:
7.59°C
Explanation:
Using the formula;
Q = m × c × ∆T
Where;
Q = amount of heat (joules)
m = mass of substance (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
According to this question;
m = 80g
c = 4.2 J/g°C.
Q = 2550J
∆T = ?
Using Q = m × c × ∆T
∆T = Q/mc
∆T = 2550 ÷ (80 × 4.2)
∆T = 2550 ÷ 336
∆T = 7.589°C
The change in temperature of water = 7.59°C.
