Answer: The correct option is A.
Explanation: Chemical reaction is defined as the reaction when there is a formation of new substance. Indicators that help in determining the chemical reaction are:
- Change in Temperature
- Appearance or disappearance of color
- Formation of bubbles
- Formation of a precipitate
- Characteristic odor
Option A: As seen from the image, there is a color change happening in the event. So, it can be considered as a chemical reaction.
Option B: In Event 1, release of heat and light is not visible. Hence, this is not the indicator for detection of chemical reaction.
Option C: In Event 2, we cannot judge the dropping of temperature just by seeing the image. Hence, this cannot be considered as a chemical reaction.
Option D: In this, the color is not mixed throughout the liquid, which means they are not reacting and hence, is not the indicator for chemical reaction.
Therefore, option A is the correct answer.
Well start by figuring the total amount of buns brought. This is found by multiplying the amount of packages brought by how many there were in each pack...
32 x 12 = 384
Now it says that you had 2 full packs left, and die extra buns. So you can figure how many are left with...
(2 x 12) + 5 = 29
Now subtract the total bins you had by how many you have left, and you'll see how many were used.
384 - 29 = 355
So 355 buns left, tell john he doesn't need so many! I hope this helps!
