Jupiter is a very large planet mainly made up of hydrogen
Answer:
<h3>The answer is 26.22 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density of iron = 7.874 g/cm³
volume = final volume of water - initial volume of water
volume = 57.65 - 54.32 = 3.33 mL
We have
mass = 7.874 × 3.33 = 26.22042
We have the final answer as
<h3>26.22 g</h3>
Hope this helps you
Not all guys will break your heart and act selfish. When you find the right one he will treat you like a queen and you’ll never have to worry about him being unfaithful. I know it doesn’t help a hurting heart, but you WILL find your soulmate one day! Just keep faith! Best wishes!
Answer:
The correct solution is "3.28 m".
Explanation:
According to the question,
Mol fraction of solvent,
= 0.0558
Molar mass of water,
= 18 g/mol
Mol of H₂O in 1000 g water,
= 55.55 mol
Now,
Let the mol of solute will be "x mol".
Total mol in solution will be "55.55 + x".
As we know,
⇒ The mol fraction of solvent = 
![x=0.0558[55.55+x]](https://tex.z-dn.net/?f=x%3D0.0558%5B55.55%2Bx%5D)
Answer:
a. bond angles c. bond length
Explanation:
Models are abstractions of the real world. They are used to present either real or hypothetical situations either visually, graphically or through mathematical expressions.
- In chemistry, to show bond angles and bond lengths, different models are used.
- One of such is the VESPR - valence shell electron pair repulsion- theory which the model upon which the bond relationships between elements in a compound is shown.
- Also, the hybridization schemes are excellent models for showing bond relationships.
