ΔH=−890.4kJ
Calculate the amount of heat (q) produced by the combustion of 3.04 L of methane at 1.52 atm under STP conditions.
Include your sign indicating if heat is absorbed or released.
Answer:
the change in internal energy of the gases is -3.0924 KJ
Explanation:
The computation of the change in internal energy of the gases is as follows;
Given that
Q = -3.1 KJ
= -3100 J
It is negative as the heat is lost from the mixture
And,
W = + 7.6 J
It is positive as the work is done in the mixture
Now we use the following equation
Delat E = Q + W
= -3100 J + 7.6 J
= -3092.4 J
= -3.0924 KJ
Hence, the change in internal energy of the gases is -3.0924 KJ

Explanation:
Science tells us that light is the reason we are able to see objects. Without light, we wouldn't be able to process the visible world. ... The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, infrared light, ultraviolet light, X-rays, and gamma rays.
Frequency = Velocity / Wavelength = Hz (m/s / m)
Velocity = Wavelength x Frequency = distance/time
Wavelength = Velocity / Frequency = meters (any length)
Step 1: Write down the equation needed to solve for velocity
Velocity = Wavelength x Frequency
Step 2: Place the known measurements into the equation
Step 3: Solve the equation.

Different types of plants use different types of carbon fixation as adaptations to varying conditions.
Please select the best answer from the choices provided
T
F
Answer: Different types of plants use different types of carbon fixation as adaptations to varying conditions.
Explanation: Different plants have evolved different types of carbon fixation methods as an adaptation towards varying conditions
Different types of plants use different types of carbon fixation as adaptations to varying conditions. The statement is True.
What is Carbon fixation?
Carbon fixation is the process by which inorganic carbon, from the atmosphere, is attached to an organic compound, usually a carbohydrate. This process is catalyzed by the enzyme RuBisCO, the most abundant enzyme on earth.
Carbon fixation is a cornerstone when it comes to the process of photosynthesis. Without carbon fixation in the Calvin cycle, photosynthesis would not be able to occur and plants would not be able to make their own food.
Therefore, Different types of plants use different types of carbon fixation as adaptations to varying conditions. The statement is True.

If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called a cold front
true or false?
(6th grade science class)
True
Explanation:
Cold, dry air against warm air creates a cold front, and visa versa warm air pushes against cold air its a warm front
Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, the given statement is true.
What is matter?Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter. Cold, dry air against warm air creates a cold front, and visa versa warm air pushes against cold air its a warm front.
Therefore, the given statement is true.
