1. Measure your waste

It is easier to manage and track your improvement on something that is measured. Start by recording the types and quantities of waste materials generated within your business.

This could just be a quick visual assessment and estimation of amount and types of waste per week. As you change how you manage your waste, you can compare and see what difference your changes make to the amount of waste disposed to landfill.

2. Reduce

To reduce the amount of waste going to landfill, consider:

can waste be avoided or reduced by the way you procure goods and services or by changing your business operations?

does another local business have a use for the waste materials produced by your business?

what materials can be targeted for recycling?

3. Recycle

Find out what options are available locally for business recycling.

4. Collection services

It is a good idea to find out how levy fees will be managed by your waste service provider, and find out more about your waste collection services—how it impacts your ability to recycle and what options are available to you.

5. Separating waste

It’s important to ensure that waste is correctly separated for recycling. Putting the wrong waste in contaminates the recycling. Check out the free-to-download recycling signage to help businesses communicate correct recycling and waste separation behaviours.

The limiting reagent is the reactant that is used up completely. This stops the reaction and no further products are made. Given the balanced chemical equation that describes the reaction, there are several ways to identify the limiting reagent.Explanation:

The energy released in nuclear reactions are far larger than that released in chemical reactions due to the release of nuclear energy from the nucleus.

Energy is released in a reaction due to the breaking of bonds are well as formation of bonds.

The quantity of energy released in reactions differs according to the reaction type involved.

When compared to chemical reactions, the energy released in nuclear reactions are very much higher because of the changes that occurs in the nucleus of the atoms involving nuclear energy.

The energy, E released in nuclear reactions is given by the formula below:

[tex]E = mc^{2}[/tex]

where m is the mass of the substance and c is the speed of light.

Therefore, the energy released in nuclear reactions are far larger than that released in chemical reactions.

941539.2 g of mass of oxygen is produced when 2000 kg of aluminium oxide is completely electrolysed.

Electrolysis is the process by which electric current is passed through a substance to effect a chemical change.

The mass of aluminium oxide Al₂O₃ = 2000 kg = 2000 000 g

Molar mass of Al₂O₃ = 101.96 g/mol

no of moles = [tex]\frac{mass }{ molar \;mass}[/tex]

no of moles of Al₂O₃ =  [tex]\frac{2000 000 g}{101.96 g/mol}[/tex]

no of moles of Al₂O₃ = 19615.4 mol

From the reaction:

4Al + 3O₂  ⇒  Al₂O₃

To determine the moles of O₂ in Al₂O₃:

Then;

19615.4 mol X [tex]\frac{3}{2}[/tex] mol of O₂ = 29423.1

The mass of oxygen now = 29423.1  × 32 g

= 941539.2 g

Hence,  941539.2 g of mass of oxygen is produced when 2000 kg of aluminium oxide is completely electrolysed.

Answer:

A pearl is not a mineral

Explanation:

Even though a pearl is made up of a few little overlapping platelets of certain minerals such as aragonite, which is the stable form of calcium carbonate which is a necessary component for sealife. Why is a pearl not a mineral though? Yes a pearl is made up of mineral compounds, but its organic origins take away its ability to be included as a mineral. Pearls do not have distinctive crystal structures and are formed by living organisms.

If the concentration of the solutions are doubled then the cell EMF is also doubled.

According to the Nernst equation, the concentration of the species determines the cell EMF as we can see form the formula;

Ecell = E°cell - 0.0592/nlogQ.

Hence, if the concentration of the solutions are doubled then the cell EMF is also doubled.

Which of these solutions is the most basic?

[OH-] = 4.3 x 10-9 M

[OH-] = 2.8 x 10-11 M

[OH-] = 6.7 x 10-10 M

[OH-] = 1.0 x 10-5 M

[OH-] = 4.3 x 10-9 M

_______________________________________

[OH-] = 2.8 x 10-11 M

_______________________________________

[OH-] = 6.7 x 10-10 M

_______________________________________

[OH-] = 1.0 x 10-5 M

_______________________________________

we know that , the solution with pH > 7 is termed as basic and more the pH ,more the basicity, hence ,the solution with the highest pH would be the strongest base out of these all which is

[OH-] = 1.0 x 10-5 M with pH = 9

Note the rule

And we can find the answer through logarithm rules basic

So

Higher the n higher the pOH

But

As we can see

Option D has least n (5)

Hence D is more basic

Explanation:

Fossil fuels include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils. When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air.

Although fossil fuels are continually formed by natural processes, they are classified as non-renewable resources because they take millions of years to form.

fossil fuels, are called nonrenewable, which means they have a limited supply and are not continuously being made or they are made very slowly

Answer:

Original: P₁ = 710 mmHg, V₁ = 14.8 mL, T₁ = (273.2 + 11.0) K = 284.2 K

New: P₂ = 370 mmHg, V₂ = ? mL, T₂ = (273.2 + 20.0) K = 293.2 K

Combined gas law: P₁V₁/T₁ = P₂V₂/T₂

Then, V₂ = V₁ × (P₁/P₂) × (T₂/T₁)

Calculated new volume, V₂ = (14.8 mL) × (710/370) × (293.2/284.2) = 29.3 mL
