When a calorimeter is used, no heat is exchanged between the contents of the container and the outside air. If an endothermic re
action is conducted inside a calorimeter filled with water, which of the following statements is not correct regarding the reaction? Answers: The total energy inside calorimeter will increase.
The thermometer will show a decrease in temperature.
The water decreases in temperature as the reaction absorbs heat.
The potential energy of the products is higher than that of the reactants.
'The total energy inside calorimeter will increase'.
Explanation:
Endothermic reaction are those chemical reaction which absorbs the energy from the surrounding. And the temperature of surrounding also decreases.
When an endothermic reaction is carried out in calorimeter, temperature inside the calorimeter decreases due to absorption of the heat from the medium in which the reaction was carried out. This fall in temperature will be shown by thermometer.
So, the incorrect statement given in the option is:
'The total energy inside calorimeter will increase'.
Your answer would be, The lower the group number, the lower the period numbers, therefore, metalloids are found in a diagonal moving down from left to right.
