A student observes that a ray of light bends where it passes from glass into water. What best explains this phenomenon? O The pr

operties of a wave change as it travels from one medium into another. O The energy of a liquid is greater than that of a solid and increases the amount of light in it. O The mass of a ray of light varies in proportion with the density of its surroundings. O A wave consumes energy in a solid but produces energy in a liquid.​

Answer:

The correct answer is - The properties of a wave change as it travels from one medium into another.

Explanation:

The bending of the light from passing through the air into the liquid is called the refraction of the light due to change its direction as it slows down as water is more denser than air with a higher refractive index. They slow and the wavelength decreases but frequency remain same

Given that cao(s) + h2o(l) → ca(oh)2(s), δh°rxn = –64.8 kj/mol, how many grams of cao must react in order to liberate 525 kj of
USPshnik [31]

Answer:

454.3 g.

Explanation:

  • From the given data:

1.0 mol of CaO liberates → – 64.8 kJ.

??? mol of CaO liberates → - 525  kJ.

∴ The no. of moles needed = (1.0 mol)(- 525 kJ)/(- 64.8 kJ) = 8.1 mol.

<em>∴ The no. of grams of CaO needed = no. of moles x molar mass</em> = (8.1 mol)(56.077 g/mol) = <em>454.3 g.</em>

What do proteins act as?
Tresset [83]

Proteins are made from long chains of smaller molecules called amino acids. These long chains are folded into particular shapes. This is important in relation to how antibodies and enzymes work.

Enzymes are biological catalysts. There are optimum temperatures and pH values at which their activity is greatest. Enzymes are also proteins. If the shape of an enzyme changes, it may no longer work (it is said to have been 'denatured'). maybe right?
