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!

The human body excretes nitrogen in the form of urea, NH₂CONH₂. The key step in its biochemical formation is the reaction of wat
Misha Larkins [42]

Mass perventage of nitrogen in urea, arginine, ornithine is   46.67%, 32.2%,21% respectively.

What is Mass perventage ?

Mass percentage is one way of representing the concentration of an element in a compound or a component in a mixture. Mass percentage is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100.

Molecular mass of urea (NH2CONH2) is= 2× (Atomic mass of N ) + 4 × (Atomic mass of H) + (Atomic mass of C) (Atomic mass of O) = 60

Mass percentage of N = Total mass of N atoms in the compoundMass of compound×100=2860×100=46.67%

chemical formula for arginine is C6H14N4O2

molar mass of C6H14N4O2=174g/mol

moles of N atoms in C6H14N4O2=4

mass of N atoms=14*4=56g

mass percent of N in C6H14N4O2=(56/174)*100=32.2%

the chemical formula for ornithine is C5H12N2O2

molar mass of C5H12N2O2=132g/mol

moles of N atoms in C5H12N2O2=2

mass of N atoms in C5H12N2O2=2*14=28

mass percent of N in C5H12N2O2=(28/132)*100=21%

Which of these statement(s) is/are true about a balloon filled with 1.00 mol N2 (g) at STP?
lara [203]

Answer:

I. The balloon has a volume of 22.4L

III. The balloon contains 6.022x10^23 molecules.

Explanation:

At stp, it has been proven that 1mole of a gas occupy 22.4L.

Therefore, option (i) is correct.

The molar mass N2 = 14.01 x 2 = 28.02g/mol

Number of mole of N2 = 1 mole

Mass of N2 =..?

Mass = mole x molar Mass

Mass of N2 = 1 x 28.02 = 28.02g.

The mass content of the balloon is 28.02g, therefore, option (ii) is wrong.

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This implies that 1 mole of N2 also contains 6.02x10^23 molecules

Therefore, option (iii) is correct.

The correct options to the question are:

Option i and option iii
