What is the equation of the line with the given slope 7 y-intercept -8?
From the given information the straight line equation is: y = 7x-8
How can you determine the y- intercept if its not given directly?
The y-intercept (or y-intercepts) of an equation is where x = 0. Replace x with zero in the equation, and solve for y.The answer depends on what information you are given - and in what form. If the equation of the curve is given in polar coordinates or in parametric form, the process is quite different to that required when given the Cartesian equation.
How do you find the length and width of a rectangle when given the area and perimeter?
By forming a quadratic equation from the information given and then the length and width can be found by solving the equation.
Does the equation 2y5x 1 represent a direct variation?
Without an equality sign the information given does not represent an equation.
Can you solve this equation 3x 96x solve for x?
Without an equality sign the information given does not qualify it to be an equation
What important information does thermochemical equation have that a regular balanced equations does not?
A thermochemical equation shows the amount of heat given out or taken in when the reaction occurs. CH4 + 2O2 = CO2 +2H2O, deltaH = -890 kJ/mol Note delta H is negative when heat is given out, exothermic and +ve when endothermic. Sorry can't do delta symbol - its a triangle!
How is thermochemical equation different from a balanced chemical equation?
A thermochemical equation includes information about the energy changes associated with a chemical reaction, such as enthalpy changes. A balanced chemical equation shows the reactants and products involved in a chemical reaction in their correct proportions. While a balanced chemical equation gives the stoichiometry of the reaction, a thermochemical equation provides additional information about the heat flow during the reaction.
What is the difference between a thermochemical equation and a traditional chemical equation?
A thermochemical equation includes the enthalpy change of a reaction, whereas a traditional chemical equation only shows the reactants and products involved in a reaction without considering energy changes. Thermochemical equations provide information about the heat absorbed or released during a reaction, while traditional chemical equations focus on the chemical identities of the species involved.
The change in energy represented by a thermochemical equation is always?
The change in energy represented by a thermochemical equation is always given in units of energy, typically kilojoules (kJ) or kilocalories (kcal), and can be either exothermic (releasing heat) or endothermic (absorbing heat).
What important information does a thermochemical equation have that a regular balanced equation does not?
A thermochemical equation includes the heat energy change associated with a reaction, typically in units of kilojoules per mole. This information allows us to understand the temperature changes during a reaction and calculate the amount of heat absorbed or released. Regular balanced equations only show the stoichiometry of reactants and products without indicating the energy changes.
What type of reaction is shown in this thermochemical equation A plus B plus Heat -- C plus D?
The reaction shown in the thermochemical equation is an exothermic reaction. This is because heat is a reactant (on the left side of the equation) and is released during the reaction.
What is the thermochemical equation for endothermic changes?
A + B + Heat → C, ΔH > 0
What is the balanced thermochemical equation for SO2?
The balanced thermochemical equation for the formation of SO2 from its elements sulfur and oxygen is: S(s) + O2(g) -> SO2(g) with ΔH = -296.8 kJ/mol
What is thermochemical equation for combustion of cyclohexane?
The thermochemical equation for the combustion of cyclohexane (C6H12) is: C6H12(l) + 9 O2(g) -> 6 CO2(g) + 6 H2O(g) This reaction is exothermic, meaning it releases energy in the form of heat. The standard enthalpy of combustion for cyclohexane is -3925 kJ/mol.
