Hello,
Question- Within the rock cycle, a metamorphic rock could become an igneous rock by going through which steps and in what order?
A. melting, cooling, crystallization
B. crystallization, melting, cooling
C. burial, compaction, cementation
D. weathering, transportation, burial
Answer- Your answer is A. Melting, cooling, crystallization.
Why- Any rock can become any rock igneous metamorphic or even condemnatory just by heating up but when it melts it becomes lava and the rock cycle starts all over again. See all it has to do to become a new phase of rock is two steps melt and cool and boom its a new phase of rock.
Important- If my answer was enough to help uou please mark me as Brainliest, Leave a thanks, and Rate my answer 5 stars thank you and have the best day ever!
This is a PV=nRT problem, commonly known as ideal gas. For this, we simply need to take what we know and plug it into the equation
Pressure x Volume = moles x ideal gas constant x tempature.
We know our pressure is 589mmHg so we can plug that in. The volume is unknown.
Then, we need to convert 8.45g of CO2 to moles. That is the grams to moles stoichiometry problem. I will not solve the problem for you, however I can set it up for you:
8.45gCO2 1 mole CO2
-------------- x --------------
1 44.01g CO2
At this point, we now have 589 x X= moles.
The ideal gas constant for mmHg should have been given to you, it is 62.4.
Then, we need to convert from celcius to kelvin. To do this, we simply add 273 to 10, since 273 is the standard unit for kelvin.
Now that we have all of our units, we can plug them into the PV=nRT formula, and solve. We are finding the V, so therefore to find it, the P (pressure) needs to equal the nRT. We would multiple nRT together to get an answer, and divide by the pressure to get the missing unit. To make sure you got the right answer, multiply P and V together to see if it equals nRT. And don't forget to round to the least number of sig figs! Hope I could be of help!
Answer:C) both its speed and its velocity.

In chemistry, orbital hybridisation (or hybridization) is the concept of mixing atomic orbitals into new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.
