Answer:

The correct answer is find the number of 1 foot cubes that fill the fish tanks.

Explanation:

Volume is defined as amount of space occupied by an object.

Number of 1 foot cubes lying on the length of fish tank ,l= 5 feet

Number of 1 foot cubes lying on the width of fish tank,w = 3 feet

Number of 1 foot cubes lying on the height of fish tank ,h= 3 feet

Volume of the cuboid fish tank will be :

l\times b\times h=5 feet\times 3 feet \times 3feet=45 feet^3

The volume of fish tanks id 45 cubic feet.

Volume well in the picture the fish tank seems to be a rectangle, so you would do V=length x width x height. So V=5x3x3=45

Answer:

single replacement

Explanation:

Step 1: Data given

single replacement = A reaction in which one element replaces a similar element in a compound. For example, a metal replaces an other metal.

The general form of a single-replacement (also called single-displacement) reaction is:

A+BC→AC+B

Decomposition = a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is:

AB→A+B

Synthesis =  A reaction that occurs when one or more compounds combines to form a complex compound:

A + B → AB

Double replacement: a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds.

The general form of a double-replacement reaction is:

AB+CD→AD+BC

Combustion reaction = a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve  O2  as one reactant.

The reaction Zn + 2HCl → ZnCl2 + H2

⇒ Does not involve O2 = NOT a combustion reaction

⇒ The compounds do not form a complex compound = NOT a synthesis

⇒ A compound does not break down into smaller substances = NOT a decomposition

⇒ There is a replacement between Zn and H. This is a <u>single replacement</u>, not a double replacement reaction.

Measurements show that unknown compound X has the following composition: element mass % carbon 41.0% hydrogen 4.58% oxygen 54.6%
anastassius [24]

Answer:

CHO

Explanation:

Carbon = 41%,  Hydrogen = 4.58%, oxygen = 54.6%

Step 1:

Divide through by their respective relative atomic masses

41/ 12,         4.58/1,         54.6/16

3.41              4.58            3.41

Step 2:

Divide by the lowest ratio:

3.41/3.41,      4.58/3.41,     3.41/3.41

1,                    1,                  1

Hence the empirical formula is CHO

5. Can you determine the number of neutrons in the nucleus of an atom by looking at the element's average atomic mass and the at
Shkiper50 [21]

Answer:

No you can't

Explanation:

The atomic number is the amount of protons in element's nucleus, that's one reason why. The second reason is that the atomic mass is protons and neutrons combined, their estimated value, which doesn't show how much neutrons are in an element. It does show combined, but not specifically neutrons
