Answer:
i think the answer is A
Explanation:
because in some areas, a regular pattern occurs of one high tide and one low tide each day,
Balance the chemical equation for the chemical reaction.
Convert the given information into moles.
Use stoichiometry for each individual reactant to find the mass of product produced.
The reactant that produces a lesser amount of product is the limiting reagent.
The reactant that produces a larger amount of product is the excess reagent.
To find the amount of remaining excess reactant, subtract the mass of excess reagent consumed from the total mass of excess reagent given.
The best answer choice here would be 'Combination'
The mass of Hydrogen is 2 g/mol
The mass of Helium is 4 g/mol
Although 1013.25 mb (760 mm Hg) is considered to be the standard atmospheric pressure at sea level, it does not mean that the pressure at this level has this value, actually this being 1011 mb.
