Because the kiln utilizes fire, fire uses oxygen and the fuel to create CO2
CO2 would be the main gas because the main components of the reactants are carbon and oxygen, which make up CO2
Answer:
Option C. +150KJ
Explanation:
Data obtained from the question include:
Heat of reactant (Hr) = 200KJ
Heat of product (Hp) = 350KJ
Change in enthalphy (ΔH) =..?
The enthalphy of the reaction can be obtained as follow:
Change in enthalphy (ΔH) = Heat of reactant (Hp) – Heat of reactant (Hr)
ΔH = Hp – Hr
ΔH = 350 – 200
ΔH = +150KJ
Therefore, the enthalphy for the reaction above is +150KJ
Answer:
C₆H₁₂O₆ and O₂
Explanation:
To know which option is correct, it important that we know the concepts of chemical equation .
A chemical equation gives us an expression of a chemical reaction in terms of symbols and formula. There are two sides to every equation. The side bearing the reactant and the side bearing the product.
The reactant is located on the left side and the product is located on the right side.
Reactant —> Product
With the above information, let us answer the question given above.
6CO₂ + 6H₂O —> C₆H₁₂O₆ + 6O₂
The products are located on the right side of the equation.
Thus, the products of the reaction is C₆H₁₂O₆ and O₂
Answer:
146
Explanation:
The mass of uranium-
238 is 238 mass units. The total mass of an element is the sum of its protons and neutrons. There are 92 protons in this isotope, and its mass is 238
, so that means that there are, 238
−
92
=
146 neutrons. Thus, as weird as it may seem, the answer must be D.
Answer:
4. C4H10
Explanation:
<u>Saturated Hydrocarbon</u>
Single bond between two carbon atoms is known as Saturated Hydrocarbons
Thus, C4H10 (Butane) is saturated hydrocarbon
