There are a couple of ways todetermine if a reaction is exothermic or endothermic. Endothermic meaning that heat is added to the reaction to make the reactants interact and exothermic meaning heat is released during the reaction between the two reactants.
In endothermic reactions you can find a triangle above the arrow.
Almost always, the first way in which biology researchers present the results of their latest research is to discuss the results of previous research that they want to build off of.
The correct answer should be B) Water vapor and carbon dioxide in the atmosphere trap heat.
The trapped heat cannot leave the atmosphere and as it is trapped, it increases the heat of the planet.
False. Pb is lower than Al in the reactivity series. It cannot replace aluminium in AlCl3
Mercury (Metal) is in liquid form at room temperature
Bromine (Non-Metal) is in liquid form at room temperature
Most of the elements are solid, 11 gases and 6 liquids
