What are some differences between a main sequence star and a red giant?
Answer:
Some notable differences between a main sequence star and a red giant are its sizes and color. Red Giants tend to typically be, well, red. The output of a red giant is so much greater than that of a main sequence. A red giant is the last stage of a main sequence star's life. Another difference is what occurs inside the star. Main sequence stars fuse hydrogen together in order to keep gravity from imploding the star, while red giants run short of hydrogen and fuses helium.

At 303 K, the volume of a gas is 30.0 ml. At constant pressure, what is the new
volume of the gas if the temperature is decreased to 283K?
Answer:
V₂ = 28 mL
Explanation:
Given data:
Initial temperature = 303 K
Initial volume = 30.0 mL
Final temperature = 283 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 30.0 mL × 283 K /303 K
V₂ = 8490 mL.K / 303 K
V₂ = 28 mL

how can you test a sample of soil for acidity or alkalinity
Answer:
Scoop a soil sample into a fresh container, add 1/2 cup of water, and mix. Then, add 1/2 cup of baking soda. If the soil bubbles or fizzes, the soil is acidic. The reaction you're seeing is the result of acidic soil coming into contact with an alkaline substance (baking soda).

At 6 atmosphere pressure, the volume of a gas is 1200 ml. What pressure is
required to reduce the volume of a gas to 200 ml without changing the
temperature?
Answer:
36 atmExplanation:
The pressure required can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the required pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question we have
[tex]P_2 = \frac{6 \times 1200}{200} = \frac{7200}{200} = \frac{72}{2} \\ [/tex]
We have the final answer as
36 atmHope this helps you

7. Calculate the average atomic mass of bromine. One isotope of bromine has an atomic mass of 78.92amu and a relative abundance of 50.69%. The other major isotope of bromine has an atomic mass of 80.92amu and a relative abundance of 49.31%.
Answer:
Average atomic mass = 79.9 amu.
Explanation:
Given data:
Average atomic mass of Bromine = ?
Atomic mass of 1st isotope = 78.92 amu
Relative abundance of 1st isotope = 50.69%
Atomic mass of 2nd isotope = 80.92 amu
Relative abundance of 1st isotope = 49.31%
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (50.69×78.92)+(80.92×49.31) /100
Average atomic mass = 4000.45 + 3990.16 / 100
Average atomic mass = 7990.61 / 100
Average atomic mass = 79.9 amu.
The process of wearing down by friction-like sand blasting is called
O exfoliiation
O erosion
O Wind Abrasion
O deposition
Answer:
Erosion
Explanation:
Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials. ... Objects transported in waves breaking on coastlines cause abrasion.

Define Triple point of water?
Triple point is that temperature, at which the substance is found in all three states i.e. solid, liquid and gas. Every substance has different triple point, because Triple point is just above the freezing point and each substance has different freezing and boiling point.
_____________________________________WATER:Water has a Melting point or Freezing Point (MP or FP) of [tex]0^0[/tex] C or 273K and Boiling point (BP) [tex]100^{0}[/tex] C or 373 K. Since the triple point is just above the MP or FP thus Triple Point of water is [tex]0.01^{0}[/tex]C or 273.16K.

if a substance has a PH of 9 is it an acid, base or nutral.
Answer:
At nine, it can still count as neutral.
Explanation:
The ph scale goes from 0 (acid) to 14 (alkaline/base). The middle would be seven, which is neutral. Nine has more alkalinity than a true neutral, but I believe it is close enough to the middle to not count as a base.
Is tomato juice a solution? state a reason for your answer.
Answer:
yes tomato juice is a solution. because it is homogenous mixture and it's ingredient dissolve in water.
Solutions are made of a solute and a solvent. Tomato juice is solution since it contains the tomato pulp and water which can be mixed well.
What is a solution?A solution is a combination of a soluble or insoluble salt and a solvent like water. There are homogenous solutions and heterogenous solutions. In the homogenous solutions the solute is completely soluble in the solvent and both exists in one phase.
In heterogenous solutions, the solute form a different phase from the solvent and appear immiscible. The components can be mixed well using stirring methods.
Tomato juice is made by the tomato pulp and water. The pulp and water is mixed well to form the juice and it appear to be one solution
Therefore, tomato juice can be considered as a solution.

When you climb to the top of a water slide, you are gaining:
O A. gravitational kinetic energy.
B. chemical potential energy.
c. gravitational potential energy.
D. chemical kinetic energy.
Answer:
C
Explanation:
You climbing the water slide gives you potential energy and your building gravitational eneergy.
When we climb the top of a water slide we are gaining gravitational kinetic energy. That is we are moving through the surface and thus we experience both kinetic energy and gravitational energy.
What is kinetic energy?Kinetic energy of a body is generated by virtue of its motion. Gravitational energy is a form of energy by which the an object attracts other object to its center of mass. Both forms of energy are directly proportional to the mass of the object.
Potential energy is generated by virtue of the position and height of the object. As the height from surface increases, potential energy increases. Potential energy and kinetic energy together called as mechanical energy of an object.
When starts moving our potential energy is converting to kinetic energy. Hence, when we climb the top of a water slide kinetic energy starts to increase. Thus, option A is correct.
