Answer : The correct option is, (D)

Explanation :

Balanced reaction : Balanced reactions are those reactions when the number of different atoms of the element present in the reactant sides is equal to the product sides.

The given unbalanced reaction is,

Zn+K_2CrO_4\rightarrow K+ZnCrO_4

The balanced chemical reaction is,

Zn+K_2CrO_4\rightarrow 2K+ZnCrO_4

Therefore, 1, 1, 2, 1 are the coefficients that would correctly balance this equation.

Convert 835g Ar to liters of Argon gas. Please Help!!!
Feliz [49]
 835 g Ar  to  liters of Argon  gas  is  calculated as    follows

find  the  moles of Ar =  mass/molar mass

= 835g /39.95  g/mol  =  20.9  moles

At  STP   1mole of  ideal  gas =  22.4 L,  what  about  20.9 moles

= 20.9 moles/1mole x 22.4 L =468.16 L  of Argon

How should the nutritionist explain why fats cannot be directly converted into carbohydrates?
lara [203]

Fats cannot be directly converted into carbohydrates during gluconeogenesis, glucose is created from oxaloacetate. However, oxaloacetate generated from fats occurs via the citric acid cycle. Because carbons from fats must enter the citric acid cycle as acetyl CoA first, fats can only indirectly become carbohydrates.

Option B

<u>Explanation:</u>

Gluconeogenesis is the process by which glucose is produced in body from non carbohydrate sources like fat, amino acids etc. This process involves the conversion of each and every product into oxaloacetate and then conversion of oxaloacetate into pyruvate and then the reverse process of Glycolysis is followed.

The concentration of oxaloacetate and ADP maintains the process. An increased amount of both of them supports the gluconeogenesis. But all products must undergo citric acid cycle to get converted into oxaloacetate. So fats are indirectly converted into glucose.

How many moles of O are in 2.45 moles of H2CO3?​
Irina-Kira [14]

Answer:

7.35 moles of oxygen

Explanation:

First of all, for 1 mole of H₂CO₃ we have 3 moles of oxygen (can be deduced from the chemical formula of the acid), then the moles of oxygen in 2.45 mole of the compound, which are given in the question, from the carbonic acid will be:  

If in        1 mole of H₂CO₃ we have 3 moles of oxygen

The in    2.45 moles of H₂CO₃ we have X moles of oxygen

X = ( 3 × 2.45 ) / 1 = 7.35 moles of oxygen
