Answer:
2 x 12.0g/mol + 1 x6 + 16.0 g/mol
Explanation:
molecular formula = C₂H₆O ( carbon= 12g/mol H= 1g O=16)
= 2 x 12 + 6 x 1 + 16
= 46 g Molecular mass
Answer:The equilibrium constant for a given reaction is [concentration of products]/[concentration of reactants].
Explanation:
Equilibrium constant=[concentration of products]/[concentration of reactants]
The concentration of reactant molecules is maximum at time 0 and it decreases as the reaction proceeds, The concentration of product molecules increases.At equilibrium the concentration of reactants and products are equal.
All the changes would occur in accordance with the LeChateliers principle.
For the given reaction the following changes would occur:
a When CO is removed from the reaction mixture so the reaction would shift towards right that is in forward direction as we are decreasing the concentration of CO so the system would try to increase the concentration of CO and that can happen by more production of CO.
b Since the above reaction is an endothermic reaction so when we would be adding heat to the system that is when we would increase the temperature the reaction would shift forwards as more heat energy is absorbed by reactants to form more products.
c When more CO₂ is added so more amount of reactants are added to the system so the system would try to decrease the amount of reactants that is CO₂ and hence more amount of products would be formed.The reaction would shift in forward direction.
d Since this reaction is endothermic in nature so when we remove the heat from reaction hence even less amount of heat is present in the system and so the reaction shift in backward direction as the reaction cannot proceed without enough amount of heat.
Answer:
0.96 g/cm
Explanation:
Density = Mass / volume
mass = 48 grams
Volume = l x h x w --> 5 x 2 x 5 = 50 cm
48 grams / 50 cm = 0.96 g/cm
Answer:
Explanation:
Carbon-14 has a mass number of 14, and Carbon-12 has a mass number of 12. Every carbon atom must have six protons, so Carbon-14 has eight neutrons and Carbon-12 has six neutrons. Elements with the same atomic number but different atomic masses are isotopes.
Answer:
COARSE ADJUSTMENT KNOB — A rapid control which allows for quick focusing by moving the objective lens or stage up and down. ... FINE ADJUSTMENT KNOB — A slow but precise control used to fine focus the image when viewing at the higher magnifications. 6.
Coarse adjustment, using the coarse adjustment knobs, raises and lowers the stage more rapidly. Fine adjustment knobs are the smaller knobs and are also used to raise and lower the stage but more slowly and in a more controlled manner under higher magnifications.
