For a double replacement reaction to take place, one of following must occur:
nickel and zinc chloride
nickel and zinc chloride
A single or double displacement/replacement reaction.
This is the reactivity series of metals.
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
A single replacement reaction involve the replacement of an element with other in the molecule as in this model:A + B-C = A-C + B.
The type of reaction that always has an element and a compound as reactants is a single displacement reaction, or a substitution reaction. These are of the form A + BC ---> AC + B.
a single replacement has one product and the double replacement has two products.
single replacement reaction
Its a combination
You can identify a single replacement reaction because the reactants are a compound + an element. The products of a single replacement reaction are found by switching the element with another element in the compound. Metals switch with metals, non-metals switch with non-metals, and the most reactive element is always in the compound. A double replacement reaction can be identified because the reactants are always compound +compound. The products would also be two compounds but the elements would switch.
No, it is a double replacement reaction. Photosynthesis is not a single reaction pathway but two, one dependent on the other. Therefore, your answer is photosynthesis is a double replacement reaction. The chemical equation for photosynthesis is: 6CO2 + 6H2O --> C6H12O6 + 6O2 Also, since you start AND end with two compounds, that also makes it a double replacement reaction.
In a single-replacment reaction, atoms of an element replace atoms of another element in a compound. In a double-replacement reaction, two positive ions trade places between different ionic compounds.
