I will walk through different captions if one I say isn’t correct.
1) As the humans impact the environment, there will be consequences such as global warming. 2) When the long-term consequences has come, human life would become more difficult and complicated.
3) If the himan life hasn’t taken care of the global, it wouldn’t be safe and consequences would attracted by this cause. (As said above.)
Thank you!
Answer:
carbohydrate, 6, a carbonyl, disaccharide
Explanation:
Fructose is an example of a ketohexose. The -hexose part of the name indicates that fructose is a carbohydrate that contains 6 carbons. <em>There are more isomers that are ketohexoses.</em>
The keto- part of the name indicates that fructose contains a carbonyl functional group. <em>In ketones, the carbonyl is in an inner carbon.</em>
Fructose can combine with glucose to form sucrose. Therefore, sucrose is a disaccharide. <em>Disaccharides are formed by the bonding of 2 monosaccharides.</em>
Answer:
Correct: B
Explanation:
The first block wont move because:
Σf=3-3=0N.
The second block will move because:
Σf:5-3=2N (direction to the right).
The third block will move because:
Σf=3N (direction to the right).
Answer:
Yes, in both cases the reactant bond must be broken before the H can bond.
Explanation:
Let us remind ourselves of the basics of the collision theory. According to this theory, chemical reaction occurs because of the collision of particles of substances in a chemical reaction system.
This means that the bond between reactants must first be broken and new bonds formed in products. Activation energy is the minimum energy required for a reaction to occur. This energy goes into the rearrangement of reactant bonds to enable them to recombine and form products.
Since the N2 bond energy is far higher than the I2 bond energy, a greater degree of energy is needed overcome the energy barrier in the reaction of H2 with N2 compared to the reaction of H2 and I2 . Therefore, the activation energy for the reaction of H2 and N2 is much higher than the activation energy for the reaction of H2 with I2.
