Chemistry
1 answer:
harkovskaia [24]3 years ago
8 0

Answer:

1) <u>Meter</u> (length), <u>Gram</u> (mass), <u>Liter</u> (volume)

2) Let 92.4 mm  =   x m

  since 1000 mm = 1 m

⇒ x = 92.4  ÷ 1000

     x = 0.924 m      

 ∴ 92.4 mm  =  <u> 0.924 m </u>

3)   Lets covert 4.2 m to cm = 420 cm

      ∴ <u>4.2 m </u>> 42 cm

Glyceraldehyde-3-phosphate is an important intermediate molecule in the cell's metabolic pathways because __________.
olga55 [171]

Answer:

Present in both catabolic and anabolic pathways

Explanation:

Glyceraldehyde-3-phosphate abbreviated as G3P occurs as intermediate in glycolysis and gluconeogenesis.

In photosynthesis, it is produced by the light independent reaction and acts as carrier for returning ADP, phosphate ions Pi, and NADP+  to the light independent pathway. Photosynthesis is a anbolic pathway.

In glycolysis, Glyceraldehyde-3-phosphate is produced by breakdown of fructose-1,6 -bisphosphate. Further Glyceraldehyde-3-phosphate converted to pyruvate and pyruvate is further used in citric acid cycle for energy production. Therefore, it is used in catabolic pathway too.

Glyceraldehyde-3-phosphate is an important intermediate molecule in the cell's metabolic pathways because it is  present in both catabolic and anabolic pathways.

2KMnO4= K2MnO4+ MnO2+O2 how many grams of KMnO4 are required to produce 1.60 grams of O2
Sergeu [11.5K]

Answer: 15.8 g of KMnO_4 will be required to produce 1.60 grams of O_2

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} O_2=\frac{1.60g}{32g/mol}=0.05moles

2KMnO_4\rightarrow K_2MnO_4+MnO_2+O_2

According to stoichiometry :

As 1 mole of O_2 is given by = 2 moles of KMnO_4

Thus 0.05 moles of O_2 is given by =\frac{2}{1}\times 0.05=0.10moles  of KMnO_4

Mass of KMnO_4=moles\times {\text {Molar mass}}=0.10moles\times 158g/mol=15.8g

Thus 15.8 g of KMnO_4 will be required to produce 1.60 grams of O_2

Are the charges in the finger attracted or repelled by the charges in the doorknob? How can you tell?
ludmilkaskok [199]

The charges in the finger are attracted by the charges in the doorknob because charges that are the same repel each other. Charges that are different attract each other. The electric field is pulled toward the other charged object if their charges are different.
