What do you do before you solve a math equation?
State the problem
What does it mean to define a variable?
State what the variable represents in the equation.
What is an equation that state that two ratios are equivalent?
That's a 'proportion'.
What is an equation that state that two rates are equal?
Rate1 = Rate2, I suppose.
Derivation of polytropic equation of state?
See wikipedia article on polytropic processes.
When was Equation of State Calculations by Fast Computing Machines created?
Equation of State Calculations by Fast Computing Machines was created in 1953.
What is the state of sulfur in following equation 2Ag(s) plus S(g)----Ag2s(s)?
In the given equation, sulfur is in the gaseous state (S(g)).
What symbol means solid in a chemical equation?
The symbol (s) indicates a solid state in a chemical equation.

What is the chemical equation of radium and oxygen?
Radium has an oxidation state of +2, Oxygen has an oxidation state of -2.....so it'll look like this Skeleton equation: Ra + O2 --> RaO.... Balanced equation 2Ra + O2---> 2RaO
What are the state symbols in a chemical equation?
State symbols in a chemical equation indicate the physical state of the reactants and products. Common state symbols include (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous (dissolved in water).
What is viral equation of state?
The viral equation of state is a mathematical relationship used to describe the behavior of gases at high pressures. It takes into account the repulsive forces between gas particles, leading to deviations from ideal gas behavior. The equation is based on the idea of a power series expansion of the pressure in terms of the gas density.
What does it mean to define a variable?
State what the variable represents in the equation.
What is an equation that state that two ratios are equivalent?
That's a 'proportion'.
How do you calculate vapour pressure from an EOS?
Use the Equation of State (EOS) in combination with the Antoine's Equation to determine vapor pressure.
What is difference between real gas and perfect gas?
Real gases deviate from ideal gas behavior at high pressures and low temperatures due to intermolecular forces and molecular volume. Perfect gases are theoretical gases that follow the ideal gas law at all conditions. Real gases have compressibility factors different from 1, while perfect gases have a compressibility factor of 1.
How do you write the chemical equation for a state change water - ice?
The chemical equation for the state change from water to ice is H2O (l) --> H2O (s). This reaction represents the process of water transitioning from liquid to solid state, where the water molecules rearrange into a crystalline structure to form ice.
