19. If the reaction of 5.87 moles of potassium with excess hydrobromic acid produced an 84.89% yleld of hydrogen gas, what was the actual yield of hydrogen gas? Unbalanced equation: K+ HBr
KBr + H2 (2 points)
O 4.98 mol H2
O 3.47 mol H2
O 2.94 mol Hz
O 249 mol H2

Explanation:

1st one trystt me

its tgat one

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
