Most likely the equation yields a new compound XY. This is a synthesis reaction. <span>Synthesis
reaction is a reaction where two or more substances combine to form a new
compound. It is a reaction which releases energy in the form of heat and
light. Therefore, it is an exothermic reaction.</span>
Since abiotic is a non living factor B would be the answer because water is abiotic
A mole of any chemical compound contains the same number of molecules - about 6.022 × 10²³ molecules.
So, 1 mole of H₂O₂, 1 mole of C₂H₂ and 1 mole of CO contain the same number of molecules.
Answer:
D . 20 grams reactant U + 3 grams reactant V → 23 grams product W
Explanation:
Law of conservation of mass states:
The mass of a closed system (As a reaction), is neither created or destroyed.
That is, the mass of reactants is equal to mass of products.
A. In reaction A 22g of reactants produce 9g of products. This reaction doesn't illustrates the law of conservation of mass.
B. 10g reactant produce 25g of products. This reaction doesn't illustrates the law of conservation of mass.
C. 19g of reactants produce 180g of products. This reaction doesn't illustrates the law of conservation of mass.
D. 23g of reactants produce 23g of products. -This is the reaction that best illustrates the Law of Conservation of Mass.
