Answer:
Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is represented by subscripts in the empirical formula.
Explanation:
The result is the molecular formula
Answer:
A. 0.228
Explanation:
Partial pressure as name suggests is partial pressures that add up to a final (total) pressure.
Here total pressure is 1.348 atm.
He + Ne + N2 = 1.348
0. 124 + 0.996 + N2 = 1.348
N2 = 0.228
Explanation:
300c = 1.8f+32= please calculate it yourself ☺
300c= k+273= 573k
Answer:
Preparation of Bases
By the direct union of a metal with oxygen Some metals when heated in air or oxygen form the oxides of the metals. ... By the action of water or steam on some active metals Some active metals like sodium and potassium react with cold water to form hydroxides with the evolution of hydrogen gas.
