Now ,
C + O2 → CO2
According to above equation, 1 mole of carbon reacts with one mole of oxygen to produce one mole of carbon dioxide.Thus this implies that 12 g of carbon reacts with 32 g of O2 to produce 44 g of CO2.
No of moles = mass of the substance/molecular mass of the substance.
In this case 1.2 g of carbon reacts with "x "g of O2 to produce 4.4 g of CO2.
No of moles of carbon in this case = 1.2÷ 12 = 0.1 moles.
No of moles of carbon dioxide formed = 4.4÷44 =0.1 moles
Thus already discussed above, 1 mole of carbon reacts with 1 mole of oxygen to produce 1 mole of carbon dioxide. Hence to produce 0.1 mole of CO2 ,0.1 mole of carbon needs to react with 0.1 mole of oxygen.
Also number of moles of O2 = mass of O2÷ molar mass of O2
Substituting number of moles of O2 as 0.1 we get
mass of O2(x) = Number of moles of O2 × Molar mass of O2
Mass of O2 (x) = 0.1 × 32= 3.2 g
Thus mass of 3.2 g O2 reacts with 1.2 g of CO2 to produce 4.4 g of CO2.
The combination of the of two or more elements is known as a compound.
A homogenous mixture has a uniform composition all throughout. They are
similar in terms of the amount of composition present in a solution. For
example, oxygen is diatomic, O2. So oxygen is a compound because it has 2
elements combined in it. It is also a homogenous mixture if there are a lot of
O2 gases present in let’s say tank. They only differ in the place where they
are present. A compound is a representation of one molecule whereas a
homogenous mixture is present in a a solution.
Answer:
Exothermic reaction
Explanation:
Consider the reaction
A + B ⟶ C
If energy is released, the product C is at a lower potential energy level than the reactants A and B (see diagram).
Conversely, the reactants A and B are at a higher energy level than the product.
B is wrong. In an endothermic reaction, the reactants A and B are at a lower energy level than the product.
C and D are both wrong. Both types of reaction can be exo- or endothermic.
The words that complete these descriptions are law, hypothesis, and experiment.
<h3>What is a law?</h3>
In science, a law is a statement that accurately describes the way a natural phenomenon occurs. Due to this, laws are created after testing a hypothesis several times. This matches Jean-Baptiste's proposal because his idea about heat flow has been tested by himself and others multiple times.
<h3>What is a hypothesis?</h3>
Different from a law, a hypothesis only states a possible explanation but this should be tested to become a law. This concept can be applied to Sadi because he only has an idea about heat flow but this has not been tested.
<h3>What is an experiment?</h3>
This is a procedure that aims at testing a hypothesis. This concept applies to James because he is carrying out an objective procedure to understand energy and heat.
