Answer:

The reactants and products determine the type of chemical reaction. If there are more products than reactants, then it is a decomposition reaction. If there are more reactants than products, it is a synthesis reaction. If oxygen is a part of the reactant, it is a combustion reaction. If one ion replaces another, it is a single replacement reaction. If there are two compounds in a reactant where cations switch, it is a double replacement reaction.

Answer:

The information of properties of the reactants and substrate that produces provide information about the type of reaction and also helps in classify the chemical reaction.

If there are fewer reactants than the products the reaction is classified as a decomposition reaction. If oxygen is present in the reaction as a reactant it is a combustion reaction. A synthesis reaction occurs if the reactants are more than the products. A single replacement reaction occurs when one ion replaces another.

Other than these reactions there are some other reactions that can be classified with knowing reactants and products.

Describe the steps to balancing a chemical equation.

scZoUnD [109]

Identify each element found in the equation. The number of atoms of each type of atom must be the same on each side of the equation once it has been balanced.

What is the net charge on each side of the equation? The net charge must be the same on each side of the equation once it has been balanced.

If possible, start with an element found in one compound on each side of the equation. Change the coefficients (the numbers in front of the compound or molecule) so that the number of atoms of the element is the same on each side of the equation. Remember, to balance an equation, you change the coefficients, not the subscripts in the formulas.

Once you have balanced one element, do the same thing with another element. Proceed until all elements have been balanced. It's easiest to leave elements found in pure form for last.

Check your work to make certain the charge on both sides of the equation is also balanced.

What can you infer if the fossil of a marine organism is found in an area that is now dry land?

Deffense [45]

Answer:

Fossils also help us to infer why dinosaurs and other organisms became extinct. Fossils tell us that there was a mass extinction at the time of the dinosaurs. They died out about 65 million years ago, along with more than half of all the other animal and plant species. ... Without plants, dinosaurs could not survive.

Give the theoretical yield, in moles, of CO2 from the reaction of 4.00 moles of C8H18 with 4.00 moles of O2. 2 C8H18(l) + 25 O2(

scoray [572]

2C₈H₁₈ + 25O₂ = 16CO₂ + 18H₂O

n(C₈H₁₈)=4 mol
n(O₂)=4 mol

C₈H₁₈:O₂=2:25 ⇒ 4:50 oxygen is the limiting reagent

n(CO₂)=16n(O₂)/25

n(CO₂)=16*4/25=2.56 mol
