While preparing for his first Chemistry exam, Jaden is studying the elements and trying to memorize their abbreviations. On test

day, he is frustrated because he studied 30 elements but can only remember the abbreviation for the last 5. This tendency to remember items at the end of a list of data is called:

Answer:

The correct option is: Recency effect

Explanation:

Serial position effect is a concept that describes the <u>effect of the position of an item in a sequence on its recall accuracy</u>. According to this theory, in a sufficiently long list of items, an individual is more likely to recall the first and the last items with greater accuracy than the middle items.

There are two types:

<u>1. Recency effect</u>: <u>The items in the end of the list or series are recalled first and more accurately.</u>

<u>2. Primacy effect</u>: The items in the beginning of the list or series are recalled first and more accurately.

In the given example, Jaden can only recall the abbreviation for the <u>last 5 elements in a list of 30 elements</u>. This tendency is known as Recency effect.

The half life for the first order conversion of A to B is 56.6 hours. How long does it take for the concentration of A to decrea
sveta [45]

Answer:

It will take 188.06 hours for the concentration of A to decrease 10.0% of its original concentration.

Explanation:

A → B

Initial concentration of the reactant = x

Final concentration of reactant = 10% of x = 0.1 x

Time taken by the sample, t = ?

Formula used :

A=A_o\times e^{-\lambda t}\\\\\lambda =\frac{0.693}{t_{\frac{1}{2}}}

where,

A_o = initial concentration of reactant

A = concentration of reactant left after the time, (t)

t_{\frac{1}{2}} = half life of the first order conversion  = 56.6 hour

\lambda = rate constant

A=A_o\times e^{-(\frac{0.693}{t_{1/2}})\times t}

Now put all the given values in this formula, we get

0.1x=x\times e^{-(\frac{0.693}{56.6 hour})\times t}

t = 188.06 hour

It will take 188.06 hours for the concentration of A to decrease 10.0% of its original concentration.

What combination of forces was the closest match? Why?
Virty [35]

Answer: COMBINED FORCES

When forces act in the same direction, they combine to make a bigger force. When they act in opposite directions, they can cancel one another out. If the forces acting on an object balance, the object does not move, but may change shape.
