Answer:

Difference between reflection and refraction :

The reflection is the phenomena based on light propagation where the light bounce back after hitting a polished surface.

For example:- light bounce back at different angles when it hits a mirror or shiny metal.

The refraction is the also a phenomena based on light propagation where the light rays passes through a transparent surface and changes its direction by bending.

For example :-when we put a spoon in a glass of water, the spoon it refract light and appears bent.

I have attached a picture which I think it is self-explanatory.

<span>Reflection is when light bounces off an object, while refraction is when light bends while passing through an object</span>

The compound Xe(CF3)2 decomposes in afirst-order reaction to elemental Xe with a half-life of 30. min.If you place 7.50 mg of Xe

Irina-Kira [14]

Answer:

$t=147.24\ min$

Explanation:

Given that:

Half life = 30 min

$t_{1/2}=\frac{\ln2}{k}$

Where, k is rate constant

So,

$k=\frac{\ln2}{t_{1/2}}$

$k=\frac{\ln2}{30}\ min^{-1}$

The rate constant, k = 0.0231 min⁻¹

Using integrated rate law for first order kinetics as:

$[A_t]=[A_0]e^{-kt}$

Where,

$[A_t]$ is the concentration at time t

$[A_0]$ is the initial concentration

Given that:

The rate constant, k = 0.0231 min⁻¹

Initial concentration $[A_0]$ = 7.50 mg

Final concentration $[A_t]$ = 0.25 mg

Time = ?

Applying in the above equation, we get that:-

$0.25=7.50e^{-0.0231\times t}$

$750e^{-0.0231t}=25$

$x=\frac{\ln \left(30\right)}{0.0231}$

$t=147.24\ min$

I am Lyosha [343]

Answer:

62.5 mg

Explanation:

Just multiply the original amount by 1/2 three times:

500 mg x 1/2 x 1/2 x 1/2 = 62.5 mg

CO, + H2O –H^2 CO^3 The reaction is which type of chemical reaction?

gulaghasi [49]

Answer:

Combination reaction or synthesis reaction

Explanation:

Given reaction:

CO + H₂O → H₂CO₃

The type of reaction shown above is a combination or synthesis reaction. A combination reaction is one in which a single product is formed from two or more reactants.

In the given reaction carbon monoxide combines with water to produce hydrogen carbonate.

The formation of compounds from the union of their constituent elements falls into this category of reactions.
