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
It used to be the National Coal Board (in the UK).
what is least positive integer that is divisible by each of the integers 1 through 7 inclusive ? a 420 b 840 c 1260 d 2520 e 5o40
Ah, that's a big number! In Roman numerals, 9999999 is written as IX CM XC IX. Each letter represents a different value, and when combined, they create this beautiful Roman numeral that tells a story of patience and perseverance. Just like painting a masterpiece, sometimes it takes many small strokes to create something truly magnificent.
(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)
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.
The equation for such circuits is given by: V=R*I +(1/C)*Integration(idt)
The major component of coal is carbon (C).
Formula: C
coal
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.
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.

Coal
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.

The chemical symbol for coal is C. Coal primarily consists of carbon, which is represented by the symbol C in the periodic table.
