Answer:
294,3
Explanation:
While g = 9,81 m/s^2 then:
![E=2[kg]*9,81[\frac{m}{s^2} ]*15[m]=294,3 [J]](https://tex.z-dn.net/?f=E%3D2%5Bkg%5D%2A9%2C81%5B%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%5D%2A15%5Bm%5D%3D294%2C3%20%5BJ%5D)
[J]
Answer:B
Explanation: the only kind of bond that is not formed by differences in electronegativity is a polar disalent bond because it does not exist, at least to my knowledge.
A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion. The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both. Have A Great Day :)
Answer:
This question appears incomplete
Explanation:
The equation for the formation of iron(III) thiocyanate complex ion is
Fe³⁺ + SCN⁻ ⇄ Fe(SCN)²⁺
Three factors affect the equilibrium of a reaction
- temperature
- pressure (in gases)
- concentration
Since the formation of Fe(SCN)²⁺ is an exothermic reaction (delta H is negative); an increase in temperature will favor the backward reaction and more reactants will be produced. When the temperature is however reduced, the forward reaction will be favored and more products will be produced.
When the concentration of the reactants increases, the forward reaction is favored and hence more Fe(SCN)²⁺ is produced. However, when the concentration of Fe(SCN)²⁺ decreases, the backward reaction is favored and more reactants are produced.
