methyl orange, methyl red,phenoptalin, merhy red
Explanation:
all this following are indicators use to check the end point of a reaction
Answer:
0.911 atm
Explanation:
In this problem, there is no change in volume of the gas, since the container is sealed.
Therefore, we can apply Gay-Lussac's law, which states that:
"For a fixed mass of an ideal gas kept at constant volume, the pressure of the gas is proportional to its absolute temperature"
Mathematically:

where
p is the gas pressure
T is the absolute temperature
For a gas undergoing a transformation, the law can be rewritten as:

where in this problem:
is the initial pressure of the gas
is the initial absolute temperature of the gas
is the final temperature of the gas
Solving for p2, we find the final pressure of the gas:

Answer:
Orange , yellow, green and blue
red coat absorbs all colors of visible light except red, so red light
is the only light left to bounce off of the coat toward our eyes.
Answer:
C. Chemical energy
Explanation:
The different types of energy listed in this question are:
A) Electrical energy: it is the energy related to the flow of electrical charges (current)
B) Nuclear energy: it is the energy contained in the nuclei of the atoms, and released during nuclear reactions
C) Chemical energy: it is the energy contained in the bonds between molecules, and it is released during chemical reactions
D) Thermal energy: it is the energy associated with the motion of molecules
Photosynthesis is the process that plants use to transform the light energy (coming from the Sun) into chemical energy. In fact, in this process, plants absorb CO2 (from the atmosphere) and solar energy (from the light), and they convert them into sugars (glucose) and oxygen. Therefore, the initial energy coming as solar energy is converted into energy of the bonds of the molecules of glucose (so, chemical energy).
So, the correct option is C).
