Asample of 23.2 grams of nitrogen gas is reacted with 23.2 g of hydrogen gas to produce ammonia. using the balanced equation below predict which of the reactants is the limiting reactant

Asample contains 16.75 g of the radioisotope u-236 and 50.25 g of its daughter isotope, th-232. how long did it take for decay to take place if one half-life of u-236 is 23 million years? 46 million years 69 million years 92 million years 115 million years

Embryos of different species look very similar, which shows that the organisms share a ancestor.

Amap that uses a range of colors and shading to represent the elevation, depth, or landscape of specific features on earth is a/an map.
