Which combustion equation violates the law of conservation of matter? a) ch4 + 2o2 -> co2 + 2h2o b) c3h8 + 6o2 -> 3co2 + 4h2o c) 2c6h14 + 19o2 -> 12co2 + 14h2o d) 2c8h18 + 25o2 -> 16co2 + 18h2o

B - C3H8 + 6O2 -> 3CO2 + 4H2O

THis is because Oxygen is not balanced on both sides, thus defying the law of conservation of matter.

On the reactants side of the equation, there are 12 Oxygen atoms, however, on the products side, there are only 10 Oxygen atoms.

Hope this helps!

Answer : The combustion equation violates the law of conservation of matter is, (B)

Explanation :

According to the law of conservation of matter, the number of atoms of each elements of reactant side must be equal to the product side in the chemical reaction. Or we can say that the mass of reactant side must be equal to the mass of product side in the chemical reaction.

(A)

This combustion equation follow the law of conservation of matter.

(B)

This combustion equation does not follow the law of conservation of matter because in this reaction, the atoms of carbon and hydrogen elements are equal on both the sides but the atoms of oxygen element on reactant side are not equal to the product side.

(C)

This combustion equation follow the law of conservation of matter.

(D)

This combustion equation follow the law of conservation of matter.

Hence, the combustion equation violates the law of conservation of matter is, equation (B)

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen

explanation:

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
