Answer:
The answer to your question is letter A.
Explanation:
Isomers are molecules that have the same molecular formula but have a different structure. The molecule from which are looking an isomer has 5 carbons and 1 double bond. Then we need to look for another molecule with these components.
A.- This molecule has 5 carbons and 1 double bond, This structure is an isomer of the first one.
B.- This molecule has 3 carbons and 1 double bond, it's not an isomer of the first structure.
C. This molecule has 4 carbons and 1 triple bonds, it's not an isomer of the first structure.
D. This molecule has 5 carbons but it doesn't have any double bond, then it's not an isomer of the first structure.
Lithium has 1 valence electron available for bonding. So its A.
The difference between relative dating and absolute dating is that relative dating is a method of sequencing events in the order in which they happened. Absolute dating is a method of estimating the age of a rock sample in years via radiometric techniques.
Answer:
Explanation:
<u>1) Data:</u>
<u />
a) Acetic acid CH₃COOH
b) molar mass of CH₃COOH: 60.052 g/mol
c) %: = 5.00%
d) d = 1.006 g/ml
e) M = ?
<u>2) Formulae:</u>
a) M = n of solute / V of solution in liters
b) n = mass in grams / molar mass
c) % = (mass of solute / mass of solution)×100
d) d = mass / volume
<u>3) Solution:</u>
a)<u> Assume a basis </u>
b) <u>Calculate the mass of that basis (1 liter of solution)</u>
- d = mass / V ⇒ mass = d × V
- mass = 1.006 g/ml × 1 liter × 1,000 ml/liter = 1006 g
c) <u>Calculate the mass of solute</u>
<u />
- % = (mass of solute / mass of solution ) × 100 ⇒
mass of solute = % × mass of solution / 100 = 5.00% × 1,006 g / 100
mass of solute = 50.3 g
d) <u>Calculate the number of moles of solute</u>
<u />
- n = mass in grams / molar mass = 50.3 g / 60.052 g/mol = 0.838 mol
e) <u>Calculate molarity</u>
- M = n / V in liter = 0.838 mol / 1 liter = 0.838 M ← answer
The answer is A I read it wrong at first the physical property is what can be observed using our senses so it's A which is density
