The correct option is A.
Speed is the ratio of the distance an object moves from a reference point to the amount of time it takes to travel the distance.
For a fixed distance, if the time required to travel the distance is less than the speed is high. However, if time to cover the same amount of distance is more than the speed is low. Therefore, the measurement of speed distance and time has an inverse relationship.
Answer:
Alkene A is more stable than alkene B
Explanation:
Complete question:
The same alkane is obtained from the catalytic hydrogenation of both alkene A and alkene B. The heat of hydrogenation of alkene A is 29.8 kcal/mol, and the heat of hydrogenation of alkene B is 31.4 kcal/mol. Which alkene is more stable ?
Step 1: Data given
The heat of hydrogenation of alkene A is 29.8 kcal/mol
The heat of hydrogenation of alkene B is 31.4 kcal/mol
Step 2: Which alkene is more stable
The smaller the heat of hydrogenation, the more stable the alkene. This because it releases less heat, and has less energy.
29.8 < 31.4
This means alkene A has a smaller heat of hydrogenation than alkene B
Alkene A is more stable than alkene B

Barium has a 2+ charge as it is in group 2 in the periodic table and so it has two electrons in its outer shell and chloride has a -1 charge on its chloride ion. So we will need two of the chloride ions as we have a 2+ charge to match the amount of charge on one barium ion- forming barium ion

burning of paper, digestion of food are the example of chemical change
digestion of food is a chemical change because if we digest a food than it will come out in the dorm of stool so can we again change that stool into food
no so it is chemical change
