Answer:
A
Explanation:
3 CARBON ATOMS 8 HYDROGEN
Answer:
Number of protons and electrons stay constant
Number of neutrons Differs
Explanation:
Isotopes are the different kinds of same element. Now, as we know quite well that an element can only have one atomic number, this means that the proton number is irrespective of the type of atom
Of the element. The proton number is the identity of the element.
As we know that the atom is electrically neutral, it means the number of electrons will always stay the same too.
Since isotopes are not alike in every respect, the number of neutrons differ. This means they have same atomic numbers but different mass numbers.
<h2>
Answer:</h2>
The water has higher specific heat capacity which affects the lakes largely in such way that the water in a lake changes temperature slowly.
<h2>
Explanation:</h2>
Evaporation is a process of liquid changing its state to gaseous state at any temperature. Water has high specific heat due to the presence of strong hydrogen bonds. Due to which it requires heat in huge amount to raise the water (in large quantity) temperature.
Thus, the molecules will be unable to gain much kinetic energy that result in changing the temperature very slowly.
<span>Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass. Dalton also stated that all compounds were composed of combinations of these atoms in defined ratios. He postulated that chemical reactions resulted in the rearrangement of the reacting atom.
