How are minerals affected by regional metamorphism?
Inessa05 [86]

When carbonate sediments are subjected to thermal or regional metamorphism, the CO2 cannot often escape and the carbonate minerals simply recrystallize; calcite and dolomite commonly form marble. Carbonate minerals can therefore be common in some metamorphic rocks.

Gaseous methane CH4 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 0.963
Anna71 [15]

Answer:

m_{H_2O}=0.676gH_2O

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the maximum mass of water by firstly setting up the undergoing chemical reaction as follows:

CH_4+2O_2\rightarrow CO_2+2H_2O

Thus, we are able to firstly calculate the moles of water produced by both methane and oxygen in order to identify the limiting reactant, which is related to maximum of water:

0.963 gCH_4*\frac{1molCH_4}{16gCH_4}*\frac{2molH_2O}{1molCH_4}  =0.120molH_2O\\\\1.2gO_2*\frac{1molO_2}{32gO_2}*\frac{2molH_2O}{2molO_2}  =0.0375molH_2O

Thus, we infer the limiting reactant is O2 and therefore we can obtain up to 0.0375 moles of water, which are related to the following mass:

m_{H_2O}=0.0375molH_2O\frac{18.02gH_2O}{1molH_2O}=0.676gH_2O

Cómo se denomina el calor que ponen en juego los sistemas materiales cuando cambian su temperatura? Seleccione una: a. Calor cin
Law Incorporation [45]

Answer:

La respuesta correcta es: b. Calor sensible

Explanation:

Al absorber calor, un sistema puede: aumentar su temperatura o cambiar de fase (es decir, pasar de un estado de agregación a otro). Los cambios de fase se producen a temperatura constante, por lo que el calor involucrado se denomina calor latente. Por ejemplo, cuando el agua líquida pasa a vapor por calentamiento a la temperatura de ebullición, esta temperatura se mantiene constante hasta que toda la masa de agua pasa al estado vapor. En cambio, cuando el sistema absorbe calor cambiando su temperatura pero permaneciendo en el mismo estado de agregación (por ejemplo, cuando calentamos agua líquida por debajo de la temperatura de ebullición), el calor involucrado se denomina calor sensible.
