Answer:
In general, the energy needed to remove an electron (the ionization energy) increases as the atomic number increases across a period.
Explanation:
Each additional proton increases the attraction between the nucleus and the electron.
Thus, it takes more energy to remove an electron as you add extra protons.
The correct option is A.
The law of definite proportion states that a given chemical compound always contains its component elements in fixed ratio irrespective of the source they are obtain from.
For instance, water is made up of two atoms of hydrogen and one atom of oxygen. Water can not be formed in any other way. Combining the oxygen and the hydrogen in another ratio will give us another thing not water.
Answer:
The answer is "As 
, at high-temperature 
and When
."
Explanation:
The equation for the reaction is:
At equilibrium,
When k=5.8(>1), the value of 
would be positive
So, 
is negative (< 0)
So if K > l, 
If the reaction is not in equilibrium so the equation is :
=
Substituting the expression:
It is the positive value for all temperatures.
So, As Q = 336, at the high temperature .
Answer:
Some of the Alpha particles shot at the gold foil bounced back.
Explanation:
Answer:
Volcanoes cool off the earth by emitting heat from its interior. They also add islands and for example, Hawaii was created / is made out of volcanoes. The deposits from volcanoes can also be used for building materials. Volcanic explosions have caused the atmosphere and oceans to form. Volcanic deposits also create land which is fertile.
