I am writing this sentence because the answer does not reach the 20 character limit. Thank you have nice day! :D Cx :P
D. respiration by plants and animals
The atomic number of the product decrease by one in the d) positron emission and the e) electron capture radioactive decay. These radioactive decays are two of three common forms of the Beta Decay which occurred when the proton released a positron and a neutron emitted an electron<span>. The Beta Decay can increase or decrease the atomic number.</span>
Explanation:
When water is heated up then its molecules move rapidly from one place to another. Hence, kinetic energy of the molecules tend to increase.
Also, K.E = 
where, T = temperature
Therefore, more is the increase in temperature more will be the mean molecular speed change in the water molecules.
As a result, mean molecular speed change increases with increase in temperature and vice-versa.
Answer:
40.444 × 10∧23 atoms
Explanation:
The mole is the unit of amount in chemistry. We know that
1 mole of sulfur = 6.02× 10∧23 atoms
The number 6.02× 10∧23 is called Avogadro's number. It is define as
" Avogadro's number is the number of molecules atoms or ions in one gram molecule of a compound, one gram atom of an element or one gram ions of a substance"
For example:
1 g of hydrogen = 1 mole of hydrogen = 6.02× 10∧23 atoms of hydrogen
18 g of water= 1 mole of water= 6.02× 10∧23 molecules of water
Given data:
moles of sulfur= 6.70
number of atoms= ?
solution:
6.70 × 6.02× 10∧23 = 40.444 × 10∧23 atoms
