The arrangement helps in easy memorizing of the elements in periodic table with the easy knowledge of oxidation state and properties of group of elements.

Explanation:

The groups consists of elements having same valence state and similar properties while the elements in periods are arranged in increasing atomic number.

So the period helps in remembering the atomic number and mass number of every element from their period number.

While the group number helps in finding the oxidation state, valence electrons and chemical properties of the elements present in that group.

Also it is easier to classify metals and non-metals and also semi-metals with the grouping of their group numbers.

Groups probably come in most handy when predicting the properties of an element. Just like people in a family all me share similar traits, elements in the same group on the periodic table also will have similar properties. Going across a period, each element has one more protein and less metallic then it’s predecessor.

Gold has a specific heat of 129 J/kg°C. How many joules of heat energy are required
ikadub [295]
To raise 1 kg by 1C, it will take 129 joules.

To raise 0.015 kg by (85-22)C, it will take (129*0.015)*22 = 42.57 joules.

The thermal efficiency of a power cycle operating in a reversible manner is found to be 50%. Assuming that the same 2 thermal re
inna [77]

Answer:

Explanation:

The thermal efficiency of a Power cycle \eta = \dfrac{Q_H -Q_c}{Q_H}

where;

\eta = 50\% = 0.5

Q_H = Heat \ flow \ from \ higher \ temperature

Q_c = Heat \ flow \ from \ lower \ temperature

0.5 = \dfrac{Q_H -Q_c}{Q_H}

0.5 Q_H = Q_H - Q_c --- (1)

Q_c = 0.5 Q_H         ---- (2)

The coefficient of performance is:

COP_R = \dfrac{Q_c}{Q_H -Q_c}

let replace the value of Q_c = 0.5 Q_H   in the above equation then;

COP_R = \dfrac{0.5Q_H}{Q_H -0.5 Q_H}

COP_R = \dfrac{0.5Q_H}{0.5 Q_H}

COP_R = 1

The

On the other hand,  the heat pump

COP_{HP} = \dfrac{Q_H}{Q_H -Q_c}

By replacing equation (1) into the above equation; we have:

COP_{HP} = \dfrac{Q_H}{0.5Q_{H}}

COP_{HP} = \dfrac{1}{0.5}

COP_{HP} =2

_______________ is the name for the permanent destruction and clearing of forests
VMariaS [17]

Answer:

<h2>Deforestation</h2>

Explanation:

__________________________________________________________

According to <em>Vocal Media,</em>

<em>__________________________________________________________</em>

<em>Deforestation is the permanent destruction of forests in order to utilize the land or trees. Typically, deforestation is clearing a lot of trees without the intention of establishing future growth. Harvesting, forest fires, and insect infestations do not count as deforestation because the affected areas will eventually grow back.</em>
