Question:

How many atoms are in 5Cao4?

Answers

There are 30 atoms in total

Explanation:

There is 5 carbon, 5 of whatever A is and 4 oxygens but since the whole symbol has been multiplied by 5 there would be 20 oxygen

So 20 + 5 + 5 = 30 atoms

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
