5 g C12H22O11/ 34g C12H22O11 = 0.01466
0.015mol / 1.000 L = 0.015 M
Answer:
a.One or more electrons will move to a higher energy orbit
Explanation:
Absorbing energy means that the electron gets excited and jumps to a higher level.
Answer:
C
Explanation:
If the enthalpy change (i.e. Δ<em>H</em>) of a reaction is negative, then the reaction releases heat and is hence exothermic.
Hence, our answer is C.
Conversely, if Δ<em>H</em> is positive, the reaction absorbs heat and is endothermic.
Δ<em>H</em> tells us nothing about the speed of the reaction.
While Δ<em>H</em> influences free-energy change (Δ<em>G</em> = Δ<em>H</em> - <em>T</em>Δ<em>S</em>), we cannot predict the sign of Δ<em>G</em> given only Δ<em>H </em>(recall that a reaction is spontaneous if Δ<em>G</em> < 0).
Answer:
The accepted views of science knowledge can change over time. Changes can result from new science observations, but can also be affected by social, political or religious convictions. To develop a deeper understanding, students need to investigate the context of the time in which science ideas were developed.
Explanation:
Answer:
The second one is the correct statement.
Explanation:
An atom consists of a dense, heavy, positively charged central part called nucleus. It consists of neutrons and protons.
The electrons revolves around the nucleus in circular paths. These electrons are called planetary electrons because they can be compared to various planets revolving around the sun and the nucleus is compared with sun.
