Answer:

D - combining it's potential energy with it's kinetic energy

Answer:

See explanation

Explanation:

While it is true that there are only about 90 naturally occurring elements, these elements are capable of combining with each other to form millions of substances.

Most of the substances that we see around us today result from a combination of one or more of these naturally occurring elements.

Let us look at three examples;

The carbohydrate in food is composed of carbon, hydrogen and oxygen

The stainless steel materials we use are composed of iron, carbon and other trace elements

Glass is made up of silicon, oxygen and other elements

Only 90 naturally occurring elements capable of combining with each other to form millions of substances.

Compounds:

When two or more elements combine in a certain ratio to form a molecule.

For example-

Water is made up of two hydrogen and one Oxygen ration is 2:1.

If hydrogen and Oxygen combine inn 2:2, they for Hydrogen peroxide.

Water gives life and Hydrogen peroxide can kill a person.

Other examples are,

Therefore, only 90 naturally occurring elements capable of combining with each other to form millions of substances.

Explanation:

Hope it helps

Organizing a community to collect waste  and implementing ecological solid waste management greatly helps to reduce pollution and landfilling also creates ideas for recycling.

In order to build and sustain an efficient waste management programme, community-based waste management are partnerships between non-governmental organizations, governmental organizations, and the affected communities.

Answer:

3000 Nm^2

Explanation:

We must remember that pressure is defined as force per unit area.  

We have been given the following information in the question;

Area of the tank= 1.5 m^2

Weight of water in the tank = 4500N

And;

P = F/A

F= force

A = area

P = 4500 N/1.5m^2

P= 3000 Nm^2

Answer:

1-1) NaHCO3 + CH3COOH --> NaCH3COO + H2O + CO2

1-2) 0.5 mole of CO2

2-1) 2C4H10 + 13O2 --> 8CO2 + 10H2O

2-2) 4 mol CO2

Explanation:

Question 1

NaHCO3 + CH3COOH --> NaCH3COO + H2O + CO2

To balance the equation, count the number of atoms on both sides of the equation

(1 Na, 1+3+1H, 1+1+1C, 3+2Oxygen) --> (1 Na, 1+1+1C, 3+2H, 2+1+2Oxygen)

Combining the pluses will give you the following

(1 Na, 5H, 3C, 5Oxygen) --> (1 Na, 3C, 5H, 5Oxygen)

Both sides are the same, therefore the chemical equation is balanced (originally).

From the equation, we can see that 1 mole of NaHCO3 produces 1 mole of CO2.

So that means 0.5 mole of NaHCO3 would produce 0.5 mole of CO2.

Question 2

C4H10 + O2 --> CO2 + H2O

Again, count the number of atoms on both sides of the equation

(4C, 10H, 2O) --> (1C, 2H, 3O)     This time left does not equal right side

You now need to find factors that can make both sides equal.

C4H10 + O2 --> 4CO2 + H2O    Now the C is balanced, let's recount

(4C, 10H, 2Oxygen) --> (4C, 8+1Oxygen, 2H)      H&O is still not balanced

C4H10 + O2 --> 4CO2 + 5H2O    Now the H is balanced, let's recount

(4C, 10H, 2Oxygen) --> (4C, 8+5Oxygen, 10H)      O is still not balanced

C4H10 + (13/2)O2 --> 4CO2 + 5H2O    Now the O is balanced

(4C, 10H, 13Oxygen) --> (4C, 13Oxygen, 10H)

But because 13/2 is a fraction, we want to eliminate that by multiplying every reactant and product by 2 (the denominator).

2C4H10 + 13O2 --> 8CO2 + 10H2O    Now it's completely balanced!

(8C, 20H, 28Oxygen) --> (8C, 28Oxygen, 20H)     Yayy! It's balanced.

Now, 2 mol C4H10 produces 8 mol CO2.

So 1 mol C4H10 produces 4 mol CO2.

Answer: Thus 9.75 moles of iron will be required.

Explanation:

The balanced chemical reaction is:

[tex]2Fe+3O_2\rightarrow 2Fe_2O_3[/tex]  

According to stoichiometry :

2 moles of [tex]Fe_2O_3[/tex] are produced by= 2 moles of [tex]Fe[/tex]

Thus 9.75 moles of [tex]Fe_2O_3[/tex] are produced by=[tex]\frac{2}{2}\times 9.75=9.75moles[/tex]  of [tex]Fe[/tex]

Thus 9.75 moles of iron will be required.

Answer:

after 4 half-lives, 125g is left

Explanation:

The half-life of a radioactive substance is the time it takes for the substance to decay by half its original mass.

In this example, we are asked to find the remaining mass after four half-lives.

What we will simply do is to reduce the starting mass by half, after each half-life decay. this is done as follows:

1st half-life decay: starting mass 2000g

final mass = 2000g ÷ 2 = 1000g

2nd half-life decay: starting mass = 1000g

final mass = 1000 ÷ 2 = 500

3rd half-life decay: starting mass = 500

final mass = 500 ÷ 2 = 250g

4th half-life decay: starting mass = 250g

final mass = 250 ÷ 2 = 125g

∴ after 4 half lives, 125g is left
