There are many forms of energy: like solar, wind, wave and thermal to name a few, but the 6 Forms of Energy we study in Needham are: Sound, Chemical, Radiant, Electric, Atomic and Mechanical. Sound Energy- is produced when an object is made to vibrate. Sound energy travels out as waves in all directions.

The complete equation representing the synthesis reaction for the formation of ammonia is: 3 H₂ + N₂ ⇒ 2 NH₃

<h3>What is a synthesis reaction?</h3>

It is a reaction in which 2 or more substances combine to form 1 product.

Let's consider the following incomplete synthesis reaction.

3 H₂ + ____ ⇒ 2 NH₃

According to Lavoisier's law, the mass and the elements must be conserved in a chemical reaction. So, since there is nitrogen to the right, the missing element to the left must be nitrogen. Molecular nitrogen is diatomic.

The complete reaction is:

3 H₂ + N₂ ⇒ 2 NH₃

The specific heat of copper metal is 0.385 J/(g × °C). How much energy must be added to a 35.0 gram sample of copper to change t

Montano1993 [528]

Q = mC∆T

where: 
q = heat 
m = mass of substance = 35.0 grams 
C = 0.385 J/g*C 
∆T = change in temperature = 65C - 20C = 45C 

q = (35.0 g)*(0.385 J/g*C)*(45C) = 606 J

Balance the following equations, and indicate whether they are combination, decomposition, or combustion reactions.1. C3H6(g)+O2

antoniya [11.8K]

Answer :

(1) This reaction is a combustion reaction.

(2) This reaction is a decomposition reaction.

(3) This reaction is a combustion reaction.

(4) This reaction is a combination reaction.

(5) This reaction is a combination reaction.

Explanation :

Combination reaction : It is a type pf reaction in which the two or more molecules combine to form a larger single molecule as a product.

Decomposition reaction : It is a type of reaction in which a single larger compound decomposes to give two or more smaller molecules as a product.

Combustion reaction : It is a type of reaction in which a hydrocarbon molecule react with the oxygen molecule to give carbon dioxide and and water as a product.

1. $C_3H_6(g)+O_2(g)\rightarrow CO_2(g)+H_2O(g)$
