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!

Dolomite, [CaMg(CO3)2] is found in a soil sample. A geochemist titrates 24.65 g of soil with 57.85 mL of 0.3315M HCl. What is th
pshichka [43]

In order to find out the %mass dolomite in the soil, calculate for the mass of dolomite using the information given from the titration procedure. You would need to multiply 57.85 ml with 0.3315 M HCl and you would get the amount of HCl in millimoles. Then multiply the amount of HCl with 1/2 (given that for every 1 mol of dolomite, 2 mol of HCl would be needed). Convert the amount of dolomite to mass by multiplying the millimoles with the molecular weight which is 184.399. Then convert the mass to grams which is 1.768 grams. Divide the mass of dolomite (1.768 grams) with the weight of soil sample. The % mass is 7.17.

Katena32 [7]
Q=mc \Delta T \\\\
Q=168,2J\\
m=4g\\
c=4.184\frac{J}{g^{o}C}\\\\
\Delta T=\frac{Q}{mc}=\frac{167,2J}{4g*4,184\frac{J}{g^{o}C}}=9,99^{o}C\\\\
\Delta T = T_{f}-T_{i}\\\\
9,99^{o}C=T_{f}-10^{o}C\\\\
T_{f}=9,99^{o}C+10^{o}C=19,99^{o}C\approx20^{o}C

Determine the approximate amount of potassium hydrogen phthalate, KHP, that you will need to neutralize 6.00 ml of 0.100 M NaOH.
Sveta_85 [38]

Answer:

potassium hydrogen phthalate KHP MOLAR MASS = 204.233 glmol

to get 1000 ml

Molar concentration = Mass concentration/Molar Mass

mass concentration = molar concentration x molar mass

mass concentration=0.1 M,

molar mass= 204.233 g/mol

so to get 1L

mass conc = 204.233 x 0.1

= 20.4233g  for 1L or 1000 ml

to get 6.00 ml

if 20.4233g is for 1000ml

then to 6.00 ml

= 20.4233 x 6 / 1000

= 0.123g for 6.00 ml

according to the equation below

NaOH(aq) + KHC8H4O4(aq) --> KNaC8H4O4(aq) + H2O(l)

number of moles of NaOH is equal to that of KHP

so the same amount will be needed too, which is

= 0.123g
