Answer:
The answer is D - near the roof.
Explanation:
Attics don't have a ton of insulation or hard cinder-block to block the goggles form seeing through it. This is why the attic can be a place where the temperature varies with the outside temperature.
Its pH value signifies the variance from the neutral point of 7, where the farther you get from 7, the stronger the base or acid

1 mole -------------- 6.02*10²³ molecules
0.0524 moles -------- molecules H2O
molecules H2O = 0.0524* ( 6.02*10²³) / 1
molecules H2O = 3.15*10²² / 1
= 3.15*10²² molecules H2O
The Enthalpy of Reaction is the adjustment in the enthalpy of a compound response that happens at a consistent weight. It is a thermodynamic unit of estimation helpful for figuring the measure of vitality per mole either discharged or created in a response.
Answer:
A
Explanation:
Protons are the ones which give rise to different elements, hence different elements have different chemical properties. Therefore, the two atoms must have different proton numbers.
The relative atomic mass of an atom is determined by the mass of the neutrons and the protons. The mass of the electrons are not included due to their negligible mass (1/1840).
Hence, due to the different proton masses, the masses of the neutrons will also differ to ensure that both atoms have the same relative atomic mass.
