Answer : The correct option is, C.

Explanation :

  • Refraction : When light is passing from rarer medium to denser medium then the light bends towards the normal line due to change in the speed of the light.
  • Reflection : When light ray falling on the surface then the refracted ray coming out from the surface. In reflection, the incident angle is equal to the reflected angle.

In a given diagram, refraction phenomenon is observed in which an incident angle of a light ray is 45^0 and the refracted angle of a light ray is 32^0 which means the light bends towards the normal.

From this we can say that the light is passing through rarer medium to denser medium. In denser medium, the speed of light slows down.

How many grams are in 3.67 moles of lithium cyanide
OLga [1]

Answer: 120.9 grams

Explanation:

Given the question : How many grams are in 3.67 moles of Lithium cyanide?

Chemical formula of lithium cyanide = LiCN

Molar mass of LiCN: Li = 6.941 ; C = 12, N = 14

LiCN = (6.941 + 12 + 14). = 32.941 g/mol

(Gram of substance / mole of substance) = (molar mass of substance / one mole)

(Gram of substance / 3.67) = (32.941 / 1)

= gram * 1 = 3.67 * 32.941

Gram of substance = 120.89347

= 120.9 grams

Which of the following statements about the combustion of glucose with oxygen to form water and carbon dioxide (C6H12O6 + 6 O2 →
worty [1.4K]

Answer:

The correct statement is:

E - The entropy of the products is greater than the entropy of the reactants.

Explanation:

C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O

As glucose is a large molecule and then it is transformed into many molecules of water and carbon dioxide, the entropy of the system increases. If the number of molecules increases, the disorder increases.

Initial state: 7 molecules (1 glucose + 6 oxygen)

Final state: 12 molecules (6 carbon dioxide + 6 water)

Luda [366]

Answer:

The correct answer is beta decay

Explanation:

When a beta particle is emitted from a radioactive atom,at that time the daughter atom that is produced have atomic mass 1 unit more than that of its parental atom.

 In the given reaction a beta particle is emitted from the carbon atom resulting in the formation nitrogen atom,The atomic mass of nitrogen atom is 7dalton which is one unit more than the atomic mass of carbon that is 6 dalton.

Buffers are substances that help resist shifts in pH by Question 10 options: 1) releasing H in acidic solutions. 2) donating H t
ehidna [41]

Answer:

5) donating H to a solution when they have been depleted and accepting H when they are in excess.

Explanation:

A buffer solution is a solution that undergoes a negligible change in pH in addition of moderate quantities of acid or alkali. In other words, a buffer solution is one that resists a change in pH on addition or dilution of small amounts of acids or alkalis.

So, from the given question:

Buffers are substances that help resist shifts in pH by donating H to a solution when they have been depleted and accepting H when they are in excess.
