Which best describes the formation of metamorphic rock?
They are formed through the cooling and hardening of magma or
lava, both below Earth's surface or on Earth's surface as volcanic
rocks.
They are formed by deposited sediment, usually at the bottom of
lakes and oceans, that is compressed over time into solid layers of
rock
They are formed as extreme weather elements, like tornadoes and
floods, break down mountains and other rock landforms into smaller
pieces.
They can be formed from any of the three rock types, withstanding
high temperatures and pressures, and forming new minerals without
melting.

Acamcorder has a power rating of 17 watts. if the output voltage from its battery is 7 volts, what current does it use?units:

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
