Answer:

2672 kj

Explanation:

C4H10 O mole wt =  48 + 10 + 16 =~ 74 gm

27200 gm / 74 gm/mole = 367.57 moles

367.57 moles * 7.27 kj/mole =

Answer:

This energy is mostly seen when the ball is kicked in the air. It is called potential energy because it has the potential to do work.

If 125 mL of a 1.1 M glucose solution is diluted to 500.0 mL , what is the molarity of the diluted solution? Express your answer
Juli2301 [7.4K]

Answer:

0.28M

Explanation:

From the question given, we obtained the following information:

C1 = 1.1 M

V1 = 125mL

V2 = 500mL

C2 =?

Using the dilution formula C1V1 = C2V2, we can easily find the molarity of the diluted solution as follows:

C1V1 = C2V2

1.1 x 125 = C2 x 500

Divide both side by 500

C2 = (1.1 x 125)/500 =

C2 = 0.28M

Atoms of different chemical elements can be differentiated based on the number of.
Alona [7]

The atoms of different chemical elements can be differentiated based on the number of protons.

Each chemical element is differentiated by his number of protons. This number of protons is also knowing as atomic number and it is represented by the letter (Z).

The atomic number represented the number of protons in the nucleus of an element. For example:

  • The element that has only 1 proton in his nucleus is Hydrogen atom.
  • The element that has 2 protons in his nucleus is Helium atom.

<h3>What is an atom?</h3>

The atom is the smallest part of the composition of matter, it is indivisible and is composed of a nucleus that has protons and neutrons, and around the nucleus there are the electrons.
