A meter of polyaramide fiber has a diameter of 710.μm , a mass of 0.059g , and takes 0.13s to produce on an industrial spinneret
1 answer:
In order to calculate the mass of fiber that can be spun in 55 min we have to determine the rate of production.
Generally speaking, all the different types of rates have in common a variable divided over time. In this case the variable we're interested in is the mass of fiber, so we have to divide the mass of fiber over the time it takes to spin, and then if we want to find the mass of fiber for any given time, we just have to multiply the time and the rate together.
Keep in mind that the time that is given to us to find the rate is in seconds, so we have to convert that to minutes
The math expression would be the following:

It represents a decomposition reaction because one reactant breaks apart and forms two products.
Explanation:
The type of chemical reaction depicted by Jane represents a decomposition reaction because on reactant breaks apart and forms two products.
In this reaction XY breaks apart to form X and Y. This is a decomposition reaction.
XY → X + Y
- Decomposition or cracking is the formation of two or more products from a single reactant.
- The break down of a compound into individual atoms or molecules falls into this category.
- The extreme instability of a compound drives such a reaction.
- The products is usually stable or it can dissociate further till it is stable.

Answer:
324.18 g/mol
Explanation:
Let the molecular mass of the antimalarial drug, Quinine is x g/mol
According to question,
Nitrogen present in the drug is 8.63% of x
So, mass of nitrogen =
Also, according to the question,
2 atoms are present in 1 molecule of the drug.
Mass of nitrogen = 14.01 amu = 14.01 g/mol (grams for 1 mole)
So, mass of nitrogen = 14.01×2 = 28.02
These 2 must be equal so,
solving for x, we get:
<u>x = 324.18 g/mol</u>
Answer : The correct option is, (A) because one of each is produced every time an
transfers from one water molecule to another.
Explanation :
As we know that, when the two water molecule combine to produced hydronium ion and hydroxide ion.
The balanced reaction will be:
Acid : It is a substance that donates hydrogen ion when dissolved in water.
Base : It is a substance that accepts hydrogen ion when dissolved in water.
From this we conclude that, the hydrogen ion are transferred from one water molecule to the another water molecule to form hydronium ion and hydroxide ion. In this reaction, one water molecule will act as a base and another water molecule will act as an acid.
Hence, the correct option is, (A)
