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.

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

The temperature of the water vapor (H,0) inside a pressure cooker increased from 295 K to 395 K. AS
the sample is heated, the pressure of the water vapor went from 21.0 kPa to
Answer:
P₂ = 28.12 KPa
Explanation:
Given data:
Initial temperature = 295 K
Final temperature= 395 K
Initial pressure = 21.0 KPa
Final pressure = ?
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
21.0 KPa / 295 K = P₂/395 K
P₂ = 21.0 KPa× 395 K / 295 K
P₂ = 8295 KPa. K /295 K
P₂ = 28.12 KPa

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.

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.

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).

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.
