Answer: 6.56g
Explanation:
No of moles = mass given/molar mass
Molar mass of ch4
C is carbon which is 12
H is hydrogen which is 1
Molar mass= 12+4(1)
Molar mass= 16g/moles
No of moles given is 0.41moles
No of moles = mass given/molar mass
Mass given = molar mass × no of moles
Mass given = 16×0.41
Mass= 6.56g
Answer:
A) solubility
B)luster
D)Density
F)magnetism
Explanation:
A physical property is one that tells us everything about what a substance is when no change is is occurring to its constituent.
Such properties can be observed with our senses or instruments or pieces of apparatus.
- Examples are luster, density, solubility, taste, odor, color, melting point, boiling point etc.
Endothermic bc of the temperature change
Answer:
A. The reaction will proceed forward forming more CH4
B. The reaction will proceed forward forming more CH4
C. Since the reaction is exothermic, raising the temperature will cause the reaction to proceed backward, thus forming C and H2.
D. Lowering the volume makes the gas particles to be more close together thereby enhancing their collisions leading to reaction. Therefore the reaction will proceed forward forming more CH4
E. Catalyst only reduce the activation energy so the reaction can proceed faster. The reaction will proceed forward forming.
F. The following will favour CH4 at equilibrium
i. Catalyst to the reaction mixture,
ii. Both adding more H2 to the reaction mixture and lowering the volume of the reaction mixture
iii. Adding more C to the reaction mixture.
