I have attached an image of the IR spectrum required to answer this question.
Looking at the IR, we can look for any clear major stretches that stand out. Immediately, looking at the spectrum, we see an intense stretch at around 1700 cm⁻¹. A stretch at this frequency is due to the C=O stretch of a carbonyl. Therefore, we know our answer must contain a carbonyl, so it could still be a ketone, aldehyde, carboxylic, ester, acid chloride or amide. However, if we look in the 3000 range of the spectrum, we see some unique pair of peaks at 2900 and 2700. These two peaks are characteristic of the sp² C-H stretch of the aldehyde.
Therefore, we can already conclude that this spectrum is due to an aldehyde based on the carbonyl stretch and the accompanying sp² C-H stretch.
Mass of lead Pb = 4.00 g (given)
Density of lead= 11.34 g/mL (given)
When lead is placed in a graduated cylinder which is partially filled with water, the volume of lead will be the volume of water displaced by it.
Density (d) of a substance is the ratio of mass (m) to the volume (m) of the substance.
The formula of density is given as:
Putting the given values of density and mass of lead, we get
Rearrange the equation, to find the volume
Therefore, volume replaced by lead is 0.353 mL
Answer:
1.26 g
Explanation:
Number of moles of ascorbic acid = concentration × volume
Concentration = 0.447 M
Volume = 16.00 mL
Number of moles = 0.447 × 16/1000
Number of moles = 7.152 × 10^-3 moles
Number of moles= mass/molar mass
Molar mass of ascorbic acid = 176.1 g/mol
Mass = 7.152 × 10^-3 moles × 176.1 g/mol
Mass = 1.26 g
Answer:
The correct answer is - the uterus.
Explanation:
The uterus or the womb is an organ that appears to be pear-shaped and it is hollow from inside where the fetus is developed and it is also called the birth canal. The uterus has two parts one is the cervix and the other is the corpus.
The cervix makes the lower part of the uterus and opens up into the vagina the external reproductive organ of the females. The corpus is the part that makes the main body of the uterus. The uterus is present between the bladder and rectum where the egg fertilized and implanted itself.
Convert 0.47g 2-naphthol to mols. mol = g/molar mass.
Using the coefficients in the balanced equation, convert mols 2-naphthol to mols 2-butoxynaphthalene then you have to Convert mol 2-butoxynaphthalene to grams. g = mols x molar mass. This is the theoretical yield.
