How many moles are in 563.9 grams of arsenic?

Chemistry
1 answer:
Aleks [24]3 years ago
6 0

Answer:

No. of moles, n = 7.52 moles

Explanation:

Given that,

Mass, m = 563.9 grams

Molar mass of arsenic = 74.92 g/mol

We need to find the number of moles in 563.9 grams of arsenic. Let it is denoted by n. It is equal to given mass divided by total molar mass.

n=\dfrac{563.9 }{74.92}\\\\=7.52\ \text{moles}

So, there are 7.52 moles in 563.9 grams of arsenic.

Answer:

The complete aerobic oxidation of glucose is coupled to the synthesis of as many as 36 molecules of ATP

Explanation:

Glycolysis, the initial stage of glucose metabolism, takes place in the cytosol and does not involve molecular O2. It produces a small amount of ATP and the three-carbon compound pyruvate. In aerobic cells, pyruvate formed in glycolysis is transported into the mitochondria, where it is oxidized by O2 to CO2. Via chemiosmotic coupling, the oxidation of pyruvate in the mitochondria generates the bulk of the ATP produced during the conversion of glucose to CO2. The biochemical pathways that oxidize glucose and fatty acids to CO2 and H2O.

Will lead (Pb) react with HgSO4?
lora16 [44]

Answer:

B

Explanation:

The electrochemical series can be used to check if a particular element has a greater activity than the other. Firstly, on the electrochemical series, it can be seen that lead is at a higher position compared to mercury. All things being equal, it will show a higher activity than mercury and hence can knock it off its salt.

Although it is the Overall standard electrode potential that tells us if a reaction is feasible or not, we can use the activity series to quickly discern if the reaction is possible or not. The overall standard electrode potential of both is positive which makes the reaction to be feasible and hence lead can display mercury off its salt

How are natural polymers and synthetic polymers similar?
Anna [14]

Answer: C) Both are made up of monomers that are linked by covalent bonds

Explanation: Polymers are large molecules which are formed by combination of small repeating units called as monomers.

Natural polymers are found in nature such as cellulose whereas synthetic polymers are synthesized in laboratories such as Nylon 6,6.

All the polymers, whether natural or synthetic are made up of monomers and are joined by covalent bonds.
