What is general and standard form?
What is general and standard form?
The general form of a quadratic function is f(x)=ax2+bx+c where a, b, and c are real numbers and a≠0. The standard form of a quadratic function is f(x)=a(x−h)2+k.
What is the difference between standard and general form of a circle?
EQUATION OF A CIRCLE. 2) The general form : x2 + y2 + Dx + Ey + F = 0, where D, E, F are constants. If the equation of a circle is in the standard form, we can easily identify the center of the circle, (h, k), and the radius, r . (a) Find the center and radius of the circle.
How do you find the general form?
Solution: To find the equation in general form, you need to determine what A,B, and C are. Let’s start this example by finding the equation in point-slope form. To change this to general form we need to get the x- and y-terms on the same side of the equation and the numbers on the other side.
What is the general equation of circle?
Equation of a Circle in General Form The general equation of any type of circle is represented by: x2 + y2 + 2gx + 2fy + c = 0, for all values of g, f and c.
What is the advantage of having the general formula?
Answer. Answer: It tells us about the quality and quantity of reactants and products involved.
What are the advantages and disadvantages of chemical energy?
What Are the Advantages of Chemical Energy?
- Most forms of chemical energy are released through combustion.
- It is an easy form of energy to stockpile.
- Many forms of chemical energy have high density loads.
- It is reasonably efficient.
- The environmental effects can be controlled.
- It isn’t a sustainable form of energy.
What are the advantages of chemical reaction?
ADVANTAGE-Chemical Reactions helps us to find new products which can be useful for future inventions in a great way. DISADVANTAGE-Chemical Reactions cost us a lot of time and money for buying various chemicals and their instruments and sometimes harmful product may be produced which may harm us and our environment.
What are the disadvantages of chemicals?
List of Disadvantages of Chemical Energy
- It can be harmful to the environment.
- It comes with a high cost.
- It can produce radioactive waste.
- It is non-renewable.
- It is not good for human health.
Where is the chemical energy stored?
Chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.
What are the limitation of a chemical equation?
1 Answer. Following are the limitations of a chemical equation: (i) A chemical equation does not tell us the physical state of the reactants and the products in the reaction. (ii) It does not tell us the actual concentration or dilution of the reactants used in the reaction.
What information do we get from chemical equation?
A balanced chemical equation gives the identity of the reactants and the products as well as the accurate number of molecules or moles of each that are consumed or produced.
What is significance of chemical equation?
Chemical equation gives information about the changes (State, chemical composition, heat energy) occurred in a chemical reaction. In order to write the chemical equation it is need to know the formulae of the elements or compounds which are involved in the chemical reaction.
How do we know when an equation is balanced?
Let’s take a closer look: If this equation is balanced, the same atoms (in number and identity) will be present as reactants and products. If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.
What are the substances you have at the start of a reaction called?
These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.
