Answer:
0.1738 M
Explanation:
Let's consider the neutralization reaction between NaOH and HBr.
NaOH + HBr → NaBr + H₂O
The moles of HBr are:
14.76 × 10⁻³ L × 0.4122 mol/L = 6.084 × 10⁻³ mol
The molar ratio of NaOH to HBr is 1:1. In the endpoint, they have reacted completely, so the moles of NaOH were 6.084 × 10⁻³ mol before the reaction.
The molarity of NaOH is:
M = 6.084 × 10⁻³ mol / 35.00 × 10⁻³ L = 0.1738 M
First, we need to find out how many moles we have of
if we are given 6.35g.
We need to calculate the molar mass of the molecule:
Cu: 63.546g
N: 14.01g * 2 = 28.02g
O: 15.999g * 6 = 95.994
Add them together to get: 187.56g
So now we need to find the number of moles we are given. This can be done by setting up a multiplication equation and cancelling the units:
So now that we know the number of moles that we have, we can use the molarity equation to find the volume of the solution. The molarity equation is:
So since we are given the molarity in the equation (0.750 M), we can plug in the molarity and moles to find the volume of the solution:
So now we know that the volume is 0.04533 Liters; however the question asks for the answer in milliliters. To do this, we must multiply by 1000:
So
the volume of the solution (<em>
in mL</em>
) is 45.33 mL.
Answer:
Add more batteries.
Explanation:
The more batteries there are in the electromagnet, the more steel/iron clips that the electromagnet can attract. Hence, this results in making the electromagnet stronger.
It is improbable that any specie with d0 or d10 will exhibit color in coordination compounds.
- If the central metal atom or ion in a coordination complex contains unfilled d orbitals, the compound exhibits color.
- Weak d–d transitions that produce spectral bands in the visible spectrum are thought to be the source of the colors.
- Hence, It is improbable that any specie with d0 or d10 will exhibit color in coordination compounds.
<h3>What are coordination compounds?</h3>
- Molecules that have one or more metal centers bonded to ligands are known as coordination compounds (atoms, ions, or molecules that donate electrons to the metal).
- These complexes may have a charge or be neutral.
- The complex is stabilized by nearby counter-ions when it is charged.
