Answer: The study of elements and their compounds and reactions with one another.
Explanation: ACTUAL DEFINITION (Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.)
Answer:
- 0.36 m/s.
Explanation:
- For the reaction: <em>a + 2b → c,</em>
<em>∵ The initial rate of the reaction = - δ[a]/δt = - 1/2 δ[b]/dt = 0.180 m/s.</em>
∴ The initial rate of the reaction = - 1/2 δ[b]/dt = 0.180 m/s.
∴ - 1/2 δ[b]/dt = 0.180 m/s.
<em>∴ δ[b]/dt </em>= (- 2)(0.180 m/s) =<em> - 0.36 m/s.</em>
1) Xenon
2) Berylium
3) Aluminium (Assuming 3p = 3rd Period)
4) Tungsten
5) Bromine
6) Xenon again
7) Indium I think
8) Strontium
9) Titanium
10) Oxygen
11) I don't understand that at all XD
12) Rutherfordium
13) Radon
14) Potassium?
15) Argon
So somebody needs to confirm 3, 7, 11, and 14, but I think the rest are correct if you load up a Periodic table
Answer:
0.2M
Explanation:
Data obtained from the question include:
C1 = 2.0 M
V1 = 100mL
V2 = 1000mL
C2 =?
Using the dilution formula C1V1 = C2V2, the molarity of the diluted solution can be obtained as follows:
C1V1 = C2V2
2 x 100 = C2 x 1000
Divide both side by the 1000
C2 = (2 x 100) / 1000
C2 = 0.2M
The molarity of the diluted solution is 0.2M
