Define each of the following wave phenomena, and give an example of where each occurs: (a) refraction;

1 answer:

5 0

Refraction is the phenomenon of change in the speed of light when the light when passes from the medium of one optical density to a medium of another optical density. The light rays also show a bending when passing through the interface of such a medium.

<h3>What causes wave refraction?</h3>

Refraction is the bending of waves due to a change in speed as they travel through different media. Waves may accelerate or decelerate when they go obliquely from one medium to another. The waves will bend more dramatically as their speed changes.

<h3>What characteristics does a wave have?</h3>

The following characteristics of waves:

Refraction is the bending of waves as they move from one medium to another due to a change in their speed.
Waves may speed up or slow down as they transition from one medium to another at an angle.

How many grams of steam at 100 °C would be required to raise the temperature

Alex777 [14]

The mass of steam required to raise the temperature of water is 3.5 g.

The given parameters;

<em>mass of the benzene, = 47.6</em>
<em>initial temperature of the benzene, = 5.5 ⁰C</em>
<em>final temperature of the benzene = 30 ⁰C</em>

The molar mass of Benzene = 78.11 g/mol

The molar mass of water = 18 g/mol

The number of moles of the Benzene is calculated as follows;

$n = \frac{47.6}{78.11} = 0.61 \ mole$

The mass of steam required is calculated as follows;

<em>heat lost by steam = heat absorbed by benzene</em>

<em />

$\frac{m}{18} \times 40.7 \times 10^3 = 47.6(1.63)(30-5.5) \ + \ 0.61 \times 9.87 \times 10^3\\\\2261.11 m = 7921.61\\\\m = \frac{7921.61}{2261.11} \\\\m = 3.5 \ g$

Thus, the mass of steam required to raise the temperature of water is 3.5 g.

How fast a reactant is used up to how fast a product is formed is _____.

STatiana [176]

Answer: B) The rate of reaction

Explanation: Rate of reaction describes the speed at which the reactants of the reaction are getting converted into the products with respect to time.

The equilibrium explains that how much concentration of reactant is in equilibrium with the product.

Solution concentration is the number of moles of solution divided by volume.

The catalyst is the substance which increases the rate of the reaction which bringing any change in other things.
