Why is a geologist most likely to find metamorphic rock underground instead of on Earth's surface? There isn't enough heat and pressure at Earth's surface.
O Weathering and erosion prevents metamorphic rock from forming at Earth's surface.
The metamorphic rock would heat up too fast on the surface of Earth
There is less pressure beneath Earth's surface.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
