Answer: The smallest unit of matter.
Explanation:
I can't answer the question without the statements but I can tell you Calorimetry means measuring amounts of heat released or received during a chemical reaction.
I would say <span>4. 40. g at 15°C because kinetic energy is related to temperature and not mass, so the lower temp would give you lower KE</span>
Answer:
23.92 g
Explanation:
Molar mass of H2SO4 = (2×1)+32+(16×4)= 2+32+48= 82g/mol
H2SO4 + 2NaOH ---> Na2SO4 + 2H2O
I mole of H2SO4 = 2 moles of NaOH
24.5/82 = 24.5/82 × 2
= 0.598 moles of NaOH will neutralize
Mass= mole× molar mass
Molar mass of NaOH= 23+16+1 = 40g/mol
Mass= 0.598 × 40 = 23.92g of NaOH
Answer:
Natural nuclear disintegration.
Explanation:
This is because it cannot be managed, like it needs no energy particle yo occur, so its natural for helium to decay.
But it is nuclear because helium decays to release an energy particle (Beta particle).
