Answer: Yes, there is sufficient sodium carbonate available.
Explanation:
In this scenario, according to the specified reaction:
Using stoichiometry, one can figure out the grams of sodium carbonate required to neutralize 1,665 g of sulfuric acid as outlined below:
Hence, the amount on hand is 2.0 kg, which leaves 0.2 kg as surplus, therefore:
A. Yes, there is sufficient sodium carbonate available.
Best regards.
The slight warm feeling noticed at the valve stem when air is pumped into the tire is likely due to the kinetic energy generated by the friction from the pump and the resultant increase in gas pressure within the tire.
Answer:
Benzoyl Chloride
Explanation:
Friedel-Craft Acylation is a reaction used to incorporate electrophiles (especially carbonyl groups) into the double bonds of aromatic compounds.
This scenario involves synthesizing benzophenone using benzene and benzoyl chloride.
Mechanism:
Step 1: Initially, benzoyl chloride reacts with a Lewis acid to create an electrophile known as oxo(phenyl)methylium.
Step 2: The second stage involves benzene participating in an electrophilic substitution reaction, where the electrophile is added.
Step 3: Finally, the aromatic nature of benzene is restored by releasing a proton.
Density is defined as the "mass per unit volume" of an object.
Thus, for an object weighing 100 grams with a volume of 100 milliliters, the density calculates to 100 grams / 100 ml.
When weighing the object, if there is water on the scale's surface, it will contribute additional weight, making the object seem heavier than its actual mass. Consequently, you might mistakenly conclude that the density is GREATER than it truly is.
For instance, if there were 5 ml of water on the scale, with water's density being 1 gram per milliliter (1 g/ml), it would add 5 grams to the object's weight. Using the previous example, the object's mass appears as 105 grams instead of 100 grams. Thus, you would calculate:
density = mass / volume
density = 105 grams / 100 ml
density = 1.05 g/ml
Thus, the effect on density would be to misleadingly suggest it is greater.
I hope this is helpful!
Best of luck
