A can of cola contains approximately 240 calories. If you consume two cans of cola each day for one week, approximately how many calories did you consume from cola?
Select one:
a. 3,400 calories
b. 70 calories
c. 1,700 calories
d. 480 calories

Answers

Answer 1
Answer: 3,400 calories
Answer 2
Well if you do 240 x 2 you get 480 and if you multiply it you get 3360

You don’t specify whether we round that number or you don’t specify whether we calculate the calories consumed weekly or daily

The oxidation # (charge) of an element called "lindenium "Ld is + 1 and the oxidation # (charge) of an element called "mendezine symbol "Mz, is -2. What is the chemical formula for the compound called lindenium mendezide?

Answers

Answer:

Ld₂Mz

General Formulas and Concepts:

Chemistry - Compounds

Valence shellsWriting chemical compoundsBalancing charges

Explanation:

Step 1: Define

"Lindenium" Ld w/ oxidation charge of +1

"Mendezine" Mz w/ oxidation charge of -2

Step 2: Write Compound

To balance out the charges to be neutral (0), we must counter balance the amount of Ld's with Mz's. We need 2 Ld's with 1 Mz to create a compound with a neutral charge:

2Ld¹⁺ + Mz²⁻

2(+1) + (-2) = (+2) + (-2) = 0 (neutral charge)

Therefore, our compound must be Ld₂Mz.

A clear, pure liquid sample is brought into the lab and exposed to an electrical current. Different gases are
produced on each of the electrodes. The sample is -

a. an element
b. an alloy
c. a compound
d. a polymer

Answers

I think the answer is an element

The sample here is a compound. The correct option is c.

What is a compound?

A chemical compound is a substance made up of many identical molecules that contain atoms from more than one chemical element and are held together by chemical bonds.

A molecule made up of only one element's atoms is thus not a compound.

The anode undergoes oxidation, while the cathode undergoes reduction. The species being oxidized provides the electrons.

An electrode in an electrochemical cell is referred to as an anode or a cathode depending on the direction of electron flow.

The electrode reacts with the electrolyte at the anode, producing electrons.

These electrons build up at the anode. Meanwhile, another chemical reaction occurs at the cathode, allowing that electrode to accept electrons.

Thus, the correct option is c.

What is the mass of 2.25 mol of the element Iron (Fe)?
Choose the correct set up from the given choices.

a. You would divided 2.25 mol by (55.84 mol divided by 1 gram)

b. You would multiply 2.25 mol by (1mol divided by 55.84 g)

c. You would multiply 2.25 mol by (55.84g divided by 1 mol)

d. You would divide 2.25 mol by (1 mol divided by 55.84g)

Answers

The answer is D I hope this help

Mole measure the number of elementary entities of a given substance that are present in a given sample. To find mass of 2.25 mol of the element Iron (Fe), we multiply 2.25 mol by (55.84g divided by 1 mol). Therefore option c is correct option.

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance.

Mathematically,

Mole of Fe element=  mass of Fe element÷ Molar mass of Fe element

mass= Mole of Fe element ×Molar mass of Fe element

Substituting the given values in above formula we get

mass= 2.25 mol× 55.84 g/mole

mass= 2.25 mol× 55.84 g/mole

To find mass of 2.25 mol of the element Iron (Fe), we multiply 2.25 mol by (55.84g divided by 1 mol).

Therefore option c is correct option.

How much radium-226 will remain from a 20 gram sample after 4800 years?

Answers

Answer:

2.5 g mass of Ra-226 will remain after 4800 years.

Explanation:

Given data:

Mass of Ra-226 = 20 g

Sample remain after 4800 years = ?

Solution:

Half life of Ra-226 = 1600 years

Number of half lives passed = T elapsed / half life

Number of half lives passed = 4800 year / 1600 year

Number of half lives passed = 3

At time zero = 20 g

At first half life = 20 g/2 = 10 g

At 2nd half life = 10 g/2 = 5 g

At 3rd half life = 5 g/2 = 2.5 g

Thus, 2.5 g mass of Ra-226 will remain after 4800 years.

C3H5OH + 3 O2 --> CO2 + H2O When balancing the equation above, how many molecules of CO2 and H2O are produced? The first half is already balanced.

Answers

Answer:

1.8069*10²⁴molecules of CO₂ and H₂O are produced.

Explanation:

C₃H₅OH + O₂ → CO₂ + H₂O

The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Then, you must balance the chemical equation. For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts

Left side: 3 C, 6 H and 3 O.

Right side: 1 C, 2 H and 3 O.

The coefficients located in front of each molecule indicate the amount of each molecule for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.  

So, balancing the C:

C₃H₅OH + O₂ → 3 CO₂ + H₂O

Then:

Left side: 3 C, 6 H and 3 O.

Right side: 3 C, 2 H and 7 O.

Now, balancing the H:

C₃H₅OH + O₂ → 3 CO₂ + 3 H₂O

Then:

Left side: 3 C, 6 H and 3 O.

Right side: 3 C, 6 H and 9 O.

Finally, balancing the O:

C₃H₅OH + 4 O₂ → 3 CO₂ + 3 H₂O

Then:

Left side: 3 C, 6 H and 9 O.

Right side: 3 C, 6 H and 9 O.

Since you have the same amount of each element on each side of the reaction, the reaction is balanced. Then 3 moles of CO₂ and 3 moles of H₂O are produced.

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and it applies to any substance.

Then the following rule of three applies: if 1 mole contains 6.023*10²³ molecules, then 3 moles of CO₂ or 3 moles of H₂O, how many molecules does it contain?

[tex]amount of molecules=\frac{3 moles* 6.023*10^{23} molecules}{1 mole}[/tex]

amount of molecules= 1.8069*10²⁴

1.8069*10²⁴ molecules of CO₂ and H₂O are produced.

Answer:

Dust and smoke.

Explanation:

Dust and smoke are two different particles present in the air. Dust and smoke are different from one another due to their origin. Smoke formed from burning of materials while dust refers to the soil particles lifted by the wind due to their light weight. Dust and smoke are similar to each other due to their small in size, infinite number means uncountable and light weight.

Air is a mixture of gases and consists of dust particles and water vapor. It consists of small to very large size of particles. Some of them include dust pollen, soot, and liquid droplets.

Dust and soot particles of the air are different as the soot is a fine black particle of carbon and tar. It is made by the incomplete combustion of air. While dust is fine dry particles of matter.

Hence they both differ.

You noticed that this metal was not a new metal. In fact, this metal was discovered years ago. You determined this when you saw the atomic emission spectrum. As you read the article, you remembered that each atomic emission spectrum is unique to each element and the atomic emission spectrum matched one that was already discovered.
