How much heat energy is required to raise the temperature of 5 kilograms of coal from 20degree C to 220 degree C?
Q = m*c*delta Tc for coal = 0.24 (depending on its origin)Q = 5*0.24*(220-20) = 240 Joulesc for anthracite coal is also given as 0.201 which will give an answer of 201 Joules

3c plus 15 over c squared minus 5 plus c over c plus 5?
(3c +15)/(c2 - 5) + c/(c + 5)= (3c + 15)/(c - 5)(c + 5) + c/(c + 5)= (3c + 15)/(c - 5)(c + 5) + [c(c - 5)/(c + 5)(c - 5)(since the common denominator is (c + 5)(c - 5)= (3c + 15)/(c - 5)(c + 5) + (c2 - 5c)/(c + 5)(c - 5)= (3c + 15 + c2 - 5c)/(c - 5)(c + 5)= (c2 - 2c + 15)/(c - 5)(c + 5)= [(c - 5)(c + 3)]/(c - 5)(c + 5) (simplify)= (c + 3)/(c + 5)
What is the burning point of coal?
The burning point of coal depends on the type of coal, but it generally ranges from 700°C to 1300°C. At these temperatures, coal combusts and releases heat energy.
What is the chemical name of coal?
The major component of coal is carbon (C).
When a series circuit comprises of a resistor and a capacitor and is connected to an ac supply the current will what?
The equation for such circuits is given by: V=R*I +(1/C)*Integration(idt)
What is the formula of coal?
Formula: C
What resources start with c?
coal
Burning coal equation?
The combustion of coal can be represented by the equation: [ C + O_2 → CO_2 ] where carbon (C) from coal combines with oxygen (O2) in the air to produce carbon dioxide (CO2) as the main product of the reaction.
What is coal formula?
The chemical formula for coal is generally C (carbon). Coal is a combustible black or brownish-black sedimentary rock composed mostly of carbon and hydrocarbons.
What type of fuel begins with c?
coal
Where does the c in fossil fuels come from?
Coal
What is the chemical equation of coal combustion?
The combustion of coal can be represented by the general equation: C + O2 → CO2 This equation shows that carbon (C) in coal reacts with oxygen (O2) to produce carbon dioxide (CO2) as the combustion product.
What is the chemical symbol for coal?
The chemical symbol for coal is C. Coal primarily consists of carbon, which is represented by the symbol C in the periodic table.
