How do you solve Hess's law problems?
write out the balanced equation that you need then write out formation equations (2-4) that will give you those reactants and products. manipulate the equations by reversing them or multiplying or dividing by whatever number. until you have what you need for the original equation. whatever you do to the equation, do it to the enthalpy for that equation. everything should add or cancel until you have the equation needed and you can add the enthalpies to get the enthalpy for that equation
According to the law of conservation of charge in alpha decay the total number of protons on one side of the equation equals the total number of protons on the other side of the equation?
false
What is the deference between the theory and law?
A theory is an explanation of a natural phenomenon based on evidence and reasoning, often used to make predictions. A law, on the other hand, describes a consistent pattern in nature, usually expressed as a mathematical equation, that has been repeatedly observed and verified through experiments. In essence, a theory explains why something happens, while a law describes what happens.
Is A law is a well-tested and widely accepted view that best explains certain scientific observations?
No, a law in science is a statement that describes a consistent pattern observed in nature, often expressed in the form of a mathematical equation. Laws do not explain why phenomena occur, but they describe what happens. Theories, on the other hand, provide explanations for why and how phenomena occur based on evidence and testing.
What is the plural word for daughter in law?
The plural of daughter-in-law is daughters-in-law.
The ideal gas law measure p ressure in?
Pressure is given as pascals in the ideal gas equation.
What are the Principles of pressure?
pascals law
How do you design hydraulic Brake system?
It follows pascals law
The ideal gas law measures pressure in?
The ideal gas law measures pressure in pascals (Pa) or atmospheres (atm).
What is the chemical equation of the law of definite composition?
This law hasn't a chemical equation !
Why boiler drum steam pressure always different from boiler main steam line pressure?
Due to pascals law
Use of air pressure lift based on pascal's law?
according to pascals law pressure is transmitted equally and undiminised in all direction. So Force=pressure x area. such machines one side area is small and other side is large. A small force is applied to small area and according to the equation it produces large force.,
What is a mathematical equation for scientific law?
There is no single equation. There are different equations for different laws.
A matematical expression of natural law?
equation
What units should you use in the ideal gas law when are is 8.314?
When the gas constant R is 8.314 J/(mol*K), the units for pressure should be in Pascals (Pa), temperature in Kelvin (K), and volume in cubic meters (m^3) to maintain consistency in the ideal gas law equation PV = nRT.
If a chemical equation is not balanced it violates what law?
If a chemical equation is not balanced, it violates the Law of Conservation of Mass. This law states that matter cannot be created or destroyed in a chemical reaction, so the number of atoms of each element must be the same on both sides of a balanced chemical equation.
What is the equation of unbalance force?
An important equation in this case is Newton's Second Law: F=ma
