Enzymes affect the rate of the reaction in both the forward and reverse directions; the reaction proceeds faster because less energy is required for molecules to react when they collide. Thus, the rate constant (k) increases. Figure 3: Lowering the Activation Energy of a Reaction by a Catalyst.

NaHCO₃ + HCl → NaCl + H₂O + CO₂
<u>Explanation:</u>
NaHCO₃ + HCl → NaCl + H₂O + CO₂
When Sodium bi carbonate (NaHCO₃) reacts with hydrochloric acid (HCl), it forms table salt (NaCl), water ( H₂O ) and Carbon di oxide (CO₂) gas is evolved.
Here base reacts with acid to form salt and it is the neutralization reaction.
Answer:
100 %
Explanation:
<em>Relative humidity</em> (RH) is the amount of water vapour in the air compared to the maximum amount it can hold, expressed as a percentage.
RH is measured by a device that has wet- and dry-bulb thermometers.
If the air is unsaturated, water will evaporate from the wet bulb and cool it. The wet-bulb temperature will be less than that of the dry bulb.
If the wet-bulb temperature is the same as the dry-bulb temperature, it means that water cannot evaporate from the wet bulb.
The atmosphere already holds as much water as it possibly can, so the relative humidity is 100 %.
Answer:
B- Lower temperature causes a reduction in movement
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space
Answer:
3–heptene or Hept–3–ene.
Explanation:
To name the compound given in the question above, we must determine the following:
1. Identify the functional group of the compound.
2. Locate the longest continuous carbon chain. This gives the parent name of the compound.
3. Identify the substituent group attached to the compound.
4. Locate the position of the double bond (i.e the functional group) by giving it the lowest possible count.
5. Combine the above to obtain the name of the compound.
Now, we shall obtain the name of the compound as follow:
1. The compound contains double bond. Hence the compound is an alkene.
2. The longest continuous carbon chain is 7 i.e heptene.
3. No substituent group is attached to the compound.
4. The double bond is located at carbon 3 since counting from the right gives the lowest count for the double bond.
5. The name of the compound is:
3–heptene or Hept–3–ene
