A bomb calorimeter can be used to mcasure the energy change of a
chemical reaction. A 0.025 sample of a
fuel is burned and found to produce
3040J of heat. Which statement is
correct?
1. The enthalpy of combustion is olki
per gram
2. The fuel must be a solid material, as
only solids can be burned in a
calorimeter
3. The enthalpy of combustion is 152 kJ
per gram
4. Thc cnthalpy of combusion is 152kJ
per molc
5. The reaction is endothermic

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

if you're asking what comes out, it's steam.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
