I think the answer is hmmm I think
Im not sure if this will help but... your subscripts in a balanced equation are used to calculate the molar mass of the compound. And your coefficients are used to get the ratios. so for example we have this balanced equation
Be3N2 + 6H2O= 3Be(OH)2 + 2NH3 and you have to find the molar mass of 6h2o, you need to multiply the subscript by the atomic mass and then add them together to get the overall molar mass. * 2(1.01) + 16.00= 18.02 g/mol
and if a question wants to know the limiting or excess regent you would use the coefficients to find out the ratio between the compounds.
The correct answer is C. As heated material gets closer to the surface, it begins to cool.
Explanation:
Convection currents involve the flow and movement of particles in gases or liquids due to changes in temperature and density. This occurs on the Earth's mantle, which is partially liquid and it is located between the core (center of Earth) and the crust composed of plates.
In this way, molten material that is near the core heats and rises as it is less dense, but once it reaches the crust it cools, and after some time it sinks again as the magma increases its density. This cycle is constant and causes the movement of the plates in the crust, that might move apart or toward other plates. According to this, the only accurate statement is "As heated material gets closer to the surface, it begins to cool".
Answer:
c a reaction that requires energy
Explanation:
because it's moving kind of like a human is being more spontaneous by running and or movement it just sounds spontaneous if you think about energy and if you think about the way it works or away human being moved it's hard to explain but it just makes sense why would it be because it's more ordered that one is definitely the one that don't make sense I just don't think it has nothing to do with what it's trying to ask you this answer just makes sense and has a better understanding
Answer:
International system. The SI unit for specific heat is joule per kelvin per kilogram (J/K/kg, J/(kg K), J K−1 kg−1, etc.). Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same as joule per degree Celsius per kilogram (J/°C/kg).
