Answer:
heat transfer by thermal energy
Explanation:cause thermal is hot air so heat transfer by thermal
Answer:
The correct answer is - option 1. the molarity of H changes by one order of magnitude.
Explanation:
pH is dependent on the concentration of H+ not on the volume of H+ or the salt content. The molarity of H+ changes by one order of magnitude with the change in pH of 1.0 unit that can be an increase or decrease in molar concentration by one order of magnitude or factor of 10.
Order of magnitude refers to the factor of ten or powers of ten. A change in the order is equal to the change of the exponent changes by ± 1
Answer:
Noble gases
Explanation:
Neon and argon have 8 electrons in their outermost shells. The elements which have 8 electrons in the outermost shell or in the valence shell,are known as the noble gases.
Answer
Avogadro's number: One mole of any substance contains 6.022×10²³ molecules
Explanation
While finding the number of moles of oxygen molecules present in 3.65 moles of Na2SO4 the conversion factor used would be Avodagro's number, which is
One mole of any substance contains 6.022×10²³ molecules.
