How do we turn petroleum into energy we use?

Chemistry
1 answer:
arlik [135]4 years ago
7 0

You don't "turn" it into energy; petroleum HAS stored energy (chemical energy).However, you can turn it into ANOTHER TYPE OF ENERGY; usually this is done by burning the petroleum, and using it to drive machinery.

Since burning fuels is wasteful (the efficiency is limited, in theory, to the Carnot efficiency of a heat engine), other options are being explored, such as chemical reactions in a fuel cell. But such technology is not yet used on a large scale.

What is the reaction rate at 1000 K K when the concentration of NO N O is increased to 0.12 M M , while the concentration of H2
marissa [1.9K]

Answer:

the reaction rate of 1,000 k is 17.28 m/s

Explanation:

The computation of the reaction rate in case when NO is increased to 0.12 M is shown below:

According to the question, data provided is as follows

NO = 0.12M

H_2 = 2.00\times 10^{-2} M

Based on the above information

Reaction rate is

= (6.0\times10^4)\times(0.12)^2\times(2\times10^{-2})

= 17.28 M/s

Hence, the reaction rate of 1,000 k is 17.28 m/s and the same is to be considered

Forest food web………….
vodka [1.7K]

Forest Food web consists of the producers, main consumers, secondary consumers, scavengers, and decomposers. Food web is the collection of the large number of food chains.

<h3>What are some examples of food webs?</h3>

Numerous food chains make up a food web. As animals seek food, a food chain only follows one way. As an example, a hawk consumes a snake following the consumption of a frog, a grasshopper, and grass. A food web illustrates the numerous relationships between plants and animals.

<h3>What are the different types of food web?</h3>

1. Primary consumers

2. Secondary consumers

3. Tertiary consumers

4. Decomposers or phytoremediators

Which of these crystals is softest: P4, ZnS, CuCl, SiO2
lorasvet [3.4K]
I think the correct answer would be the first option. It is the solid phosphorus (P4) that will be the softest among these crystals. P4 is held by covalent bonding or sharing of electrons between atoms while ZnS, CuCl and SiO2 are being held by ionic bonding. Covalent bonding involves the overlapping of orbitals while ionic bonding has separation of the charges. Although covalent bonding is a strong type of bond, ionic bonding is much stronger as compared to the former. Being stronger, the compounds mentioned above with this type of bonding would tend to be harder than phosphorus which has covalent bonding only.

Study the image, which shows an air mass moving into a region.
DanielleElmas [232]

thunderstorms and heavy rain

Explanation:

The weather in a region with an incoming air mass made up of moist air is predominantly that of thunderstorms and heavy rain.

Moist air brings in rainfall and thunderstorms. They are peculiar and predominant in tropical regions of the world .

  • A moist air is an air mass that is moisture laden or full of water vapor.
  • They are usually formed where evaporation of water vapor from sea water is very high.
  • The evaporated water is warmer and lighter than the surrounding air.
  • By virtue of this, it moves inland and condenses to form massive rainfall accompanied by thunderstorm.
