In the energy graph of an endothermic reaction, the reactants would appear at a lower energy state than the products.
<h3>What is an endothermic reaction?</h3>
An endothermic reaction is a reaction in which heat is absirbed from the surroundings in order for the reaction to proceed.
In endothermic reactions, the heat content of the products is higher than the heat content of the reactants.
Therefore, in the energy graph of an endothermic reaction, the reactants would appear at a lower energy state than the products.

A one way trip going 60mph took 30 minutes longer that the first trip going 70 mph. How far was the trip
Answer:
12 more oxygen
Explanation:
An atom is the smallest particles that can take part in a chemical reaction
The given compounds are:
3Mg₃(PO₄)₂
Number of oxygen atoms = 3[2 x 4] = 24 oxygen atoms
For;
4Al₂O₃;
Number of oxygen atoms = 4 x 3 = 12 oxygen atoms
In 3Mg₃(PO₄)₂ , there are 24 - 12 = 12 more oxygen atoms than in 4Al₂O₃;
Answer:
Volcanoes, burning fossil fuels, and respiration of organisms.
Explanation:
Volcanoes, burning fossil fuels, and respiration of organisms releases carbondioxide that forms atmospheric carbondioxide. The carbon enters in the biosphere through the process of photosynthesis. In plants, carbondioxide enters in the plant body which is used as a reactant from which food is prepared. The carbon present in the plant body in the form of glucose which can be transferred into another organism due to feeding of organisms. The organism released this carbon in the form of carbondioxide when the eaten food is broken down for the release of energy. In that way, carbon moves from biosphere to the atmosphere whereas Volcanoes and burning fossil fuels releases carbon in the atmosphere, in this way carbon moves from lithosphere to atmosphere.
