How can one determine redox reactions?
Redox reactions can be determined by looking for changes in oxidation numbers of elements involved in the reaction. Oxidation involves an increase in oxidation number, while reduction involves a decrease. If there is a change in oxidation numbers, it indicates a redox reaction.
In a chemical equation numbers often appear in front of a chemical formula. What do these numbers indicate?
The numbers in front of a chemical formula, known as coefficients, indicate the ratio of each substance involved in the reaction. They show the relative amounts of reactants and products that participate in the reaction.
What is the large numbers in front of some of the formulas called?
The large numbers in front of some chemical formulas are called coefficients. They represent the ratio of moles of each substance in a chemical reaction and are used to balance the equation.
What are the large numbers in front of some of formulas?
Those large numbers are coefficients, which represent the number of units of each substance involved in a chemical reaction. They indicate the relative amounts of each reactant and product participating in the reaction.
The change in the oxidation number of Mn is?
The change in oxidation number of Mn in a reaction is determined by the difference in oxidation numbers before and after the reaction. For example, in the reaction MnO2 → Mn2O3, the oxidation number changes from +4 to +3, resulting in a decrease of 1.
Redox equations are what when the total increase in oxidation numbers equals the total decrease in oxidation numbers?
Redox equations are considered balanced when the total increase in oxidation numbers equals the total decrease in oxidation numbers. This balance ensures that the number of electrons lost in oxidation matches the number of electrons gained in reduction. By achieving this equilibrium, the conservation of charge and mass is maintained in the chemical reaction. Consequently, the overall reaction accurately reflects the transfer of electrons between species.

What are the similarities and difference between enzymes and chemical catalyst?
so the similarity is that they both speed up the reaction and both have special temperatures they best work at the only difference between them is that enzymes are found in humans and are not made by humans on particular purpose,whereas chemical catalysts are made by people and are not naturaly developed
What does exponential mean?
Numbers that are raised to an exponent either increase or decrease at an extremely fast rate.
How do you find a percentage increase decrease between two numbers?
In order to find the percentage increase and decrease between to numbers are easy. All you have to is subtract the number you start out with to the number it becomes.
What chemical equation has equal numbers of reactant and product atoms?
Any chemical reaction.
What indicates the relative numbers of reactants and products in a chemical reaction?
The coefficients in a balanced chemical equation indicate the relative numbers of reactants and products in a chemical reaction. Each coefficient represents the moles of each substance involved in the reaction.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
In a chemical equation numbers often appear in front of a chemical formula. What do these numbers indicate?

What are some ways to describe the relationship between sets of numbers?
by their increase or decrease
What is the difference between multiplying and dividing?
when multiplying the numbers increase unless it is multiplied by a decimal, it will then decrease. when dividing the numbers are divided (splitted) therefor it decreases unless it is divided by a decimal, it will then increase. Decrease means 'gets smaller or less' Increase means 'getting bigger or more'
What does exponentially?
Numbers that are raised to an exponent either increase or decrease at an extremely fast rate.
