What is biomass energy? How does it work? (2-3 sentences is good enough c:)

Chemistry

Delvig [45]2 years ago

Answer:

Biomass’ is a fancy word for something very simple: stuff that’s found in nature. People have used biomass energy ever since the very first cave-dwelling person thought to make a fire out of wood!

Wood can be used in biomass energy production

Today, biomass power plants use everything from animal waste to wood pellets to create electricity. There are lots of advantages to biomass energy, which is a renewable energy source. But there’s also some debate about whether it’s the greenest type of energy around. Here at OVO, we chose to remove biomass from our fuel mix in 2017, in favour of cleaner energy sources: wind, solar, hydro and tidal energy.

What is biomass energy?

Biomass is made up of living things (or things that were once living). This can include any plant or animal material, such as sugarcane or corn crops, wood chips, or even dung.

All these types of biomass contain energy, because they’re organic materials. So, whether they started life as plants or animals, they’ve all absorbed chemical energy naturally from the sun.

When they’re used as biomass, these materials are called ‘feedstocks’.Sources of biomass energy

How does biomass energy work? Biomass energy production explained

Biomass feedstocks can be used to create 3 types of energy:

Heat

Electricity

Biofuels, such as biodiesel

Some biomass plants are multi-taskers, creating both heat and electricity. These are known as CHP (Combined Heat and Power) plants.

So, how do biomass plants create heat? Simple: by burning feedstocks, just like our ancestors have done for thousands of years.

Read on to find out how biomass energy production turns wood into electricity or diesel.

How can biomass generate electricity?

Biomass can generate electricity in a number of ways – but the most common is ‘direct combustion’. This means burning the agricultural waste or wood to heat water. This produces steam, which spins turbines.

In some biomass plants, the extra steam can also be used in on-site manufacturing processes, or for heating. This makes the whole process even more energy efficient. Smart, right?

There are many other ways to generate electricity using biomass. Some scientists are even exploring the possibility of using what we’ll politely call ‘human waste’ to power homes!

(WILL GIVE BRAINLIEST IF YOU ANSWER ALL 4) Chemistry
Kitty [74]

Answer:

See explanations

Explanation:

a. Molarity = moles/Volume in Liters = 5moles/2Liters = 2.5M in NaCl

b. Freezing Pt Depression

     1. Sprinkling salt on icy surfaces

    2. Using antifreeze in automobile cooling systems

    3. <em>Not an application </em>

    4. Using salt to make ice cream

c. pOH = -log[OHˉ] = -log(1x10ˉ¹⁰) = -(-10) = 10 => pH = 14 – pOH = 14 – 10 = 4

d. H₂O + NH₃ => NH₄⁺ + OHˉ => Bronsted Acid is H₂O  (proton donor)

Calculate the mean kinetic energy {e1rans) in joules of the following molecules at 350 k: (a) he, (b) co2, and (c) uf6. explain
Lady bird [3.3K]

The mean kinetic energy per molecule is , where  is the Boltzmann constant and T is the absolute temperature.

So at 1000°C, the T = 1273.15 K, kB=1.38 × 10-23, therefore the mean kinetic energy is 2.635 × 10⁻²⁰J.

<h3><u>What is Kinetic energy ?</u></h3>

The energy an item has as a result of motion is known as kinetic energy.

A force must be applied to an item in order to accelerate it. We must put forth effort in order to apply a force. After the job is finished, energy is transferred to the item, which then moves at a new, constant speed. Kinetic energy is the type of energy that is transmitted and is dependent on the mass and speed attained.

Kinetic energy may be converted into other types of energy and transported between things. A flying squirrel may run into a chipmunk that is standing still, for instance. Some of the squirrel's original kinetic energy may have been transferred to the chipmunk or changed into another kind of energy after the impact.
