What Is Combination Reaction With Example? An example of a combination reaction is when hydrogen and chlorine react to form hydrochloric acid: The subscripts in the chemical reaction in this image refer to the states of matter. These states of matter can be classified as solid (s), liquid (l), gas (g) and an aqueous solution
What Does It Mean If The Arrow In A Chemical Reaction Goes In Both Directions? The double arrow denotes a reversible reaction. The reactants become products and the products can become reactants again using the same process. What does the arrow indicate in a chemical equation? Reaction arrows are used to describe the state or
What Does The Symbol Mean In A Chemical Equation? Often chemical equations are written showing the state that each substance is in. The (s) sign means that the compound is a solid. The (l) sign means the substance is a liquid. The (aq) sign stands for aqueous in water and means the compound is dissolved
What Is Combination And Give Example? A combination is a selection of all or part of a set of objects, without regard to the order in which objects are selected. For example, suppose we have a set of three letters: A, B, and C. … Each possible selection would be an example of a combination.
What Does S Represent In A Chemical Equation? Symbol Meaning (s) indicates that the substance is in a solid state an alternative way of representing a substance in a solid state (aq) indicates that the substance is dissolved in water – the aq comes from aqueous indicates that heat is applied to make the reaction
Which Of The Equation Is Balanced? D. A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both
What Type Of Reaction Is Photosynthesis In All Of Its Entirety? Photosynthesis in its entirety is an anabolic, nonspontaneous (endergonic What type of reaction is photosynthesis? Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves.
