Answer:
CH4(g) + 2O2(g) -------> CO2(g) + 2H2O(g)
Explanation:
Even though the question is incomplete because the equations are missing. However, one thing that is clear from the question is that the reaction is a combustion reaction.
A combustion reaction is a type of reaction that produces heat and light. The mixture of methane and oxygen yielded a brief, large flame which shows that combustion has taken place according to the equation shown above.
Explain why a flash of green light made flubber so energetic
Answer:
The flash of green light may give off some type of energy that only emits from green light which probably energizes the Flubber
Explanation:
A flubber is a rubber like polymer that absorbs and amplifies energy. A flubber absorbs energy from a light source and electrons present in it are excited in order to emit light of higher wavelength. The green light absorbed by the flubber to emit longer wavelength of light emitting more energy.

Vehicles use diesel fuels. Which one of these energy transformations takes place when the fuel is used by the engine
Answer:
A
Explanation:
I would say a because we all know that kinetic energy is energy in motion and fuel is an example of chemical energy. So it must be from chemical to kinetic energy.
Explain how cross cutting principles (intrusions, inclusions, faults) help to determine the relative age of a rock layer.
Answer:
The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. ... So the fault must be the youngest formation that is seen. The intrusion (D) cuts through the three sedimentary rock layers, so it must be younger than those layers

Which one of the following is an example of a difficulty caused by thermal
expansion?
O A. The siding on a house buckles on a hot day.
OB. Watery iced tea
OC. Smog in the air during summer heat
OD. lce cream not getting hard
Answer: A
Explanation:just passed it
Answer:
A. The siding on a house buckles on a hot day
Explanation:
The key word in this question is EXPANSION. Without even knowing the siding expands causing it to buckle when it's hot, you can use process of elimination. It can't be answer B because watered down iced tea would most likely be as a result of the ice melting which is the opposite of expanding. It can't be C because air is not solidified and therefore can't expand. Lastly, D cannot be it because ice cream expands when cold, causing it to become hard. If it's not hardening then it's not expanding. This is also the correct answer on a p e.x

A rectangular box has the following dimensions on the inside: 5 cm x 5 cm x 10 cm. What volume can the box hold, in milliliters?
- 20 mL
- 259 mL
- 25 mL
- 50 mL
Answer:
The volume in milliliters is 250mL
Explanation:
The volume of a rectangle is obtained using the equation:
Volume = Length * Width * Height
In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:
Volume = 5cm * 5cm * 10cm
Volume = 250cm³
1mL = 1cm³.
That means the volume in milliliters is 250mL
What is the speed of a car that has traveled 100 miles in 20 hours?
|
Answer:
5 mph
Explanation:
100 miles, 20 hours (divide by 2)
50 miles, 10 hours (divide by 2)
25 miles, 5 hours (divide by 2)
divide both sides by 5
5 miles, 1 hour
