Putting it all Together: Argument From Evidence

Chemistry
1 answer:
vagabundo [1.1K]3 years ago
4 0

Answer:

The reaction involved in a campfire (burning of wood) includes:

${{C}_{6}}{{H}_{12}}{{O}_{6}}+{{O}_{2}}\xrightarrow{\Delta }C{{O}_{2}}(g)+{{H}_{2}}O(g)+Energy+Ash$

Explanation:

We can clearly find here that when wood burns in presence of oxygen, there is a loss of mass in the form of gaseous products. Thus, in this case, the law of conservation of mass does not come true.

I support Lisa’s statement but there is a fact associated with the law of conservation of mass. The law stands true only when there is a definite mass of the reactants and products mentioned.

<span>The energy that was produced is called, heat combustion. It is an energy released in the form of heat when chemicals are mixed. An explosion of light and sound are the common characteristics of heat combustion. The chemical reaction takes place because of the presence of oxygen and hydrocarbon or organic molecule substances that when mixed form carbon dioxide and water which then releases heat and explosive characteristics.</span>

What is an example of a cation<br><br> what’s an example of a cation
Simora [160]

Answer:

Mg+

Explanation:

Cation is an ion that has lost its electron(s).

So, it has a positive charge.

Any ion with a positive charge (superscript has a + sign) is a cation.

Ozone decomposes to oxygen according to the equation 2 O3(g) → 3 O2(g). Write the equation that relates the rate expressions for
Roman55 [17]

Answer:

Check explanation.

Explanation:

The rate of reaction can be defined as the speed at which concentration of Reactant(s) is/are being converted into product(s) or it can be defined as the rate at which the concentration of Reactant(s) disappear and the rate at which the product(s) forms.

For instance, in the Example below;

aA + bB-------> cC + dD. Where a,b,c and d are the number of moles of A,B,C and D respectively.

The rate of Reaction can be expressed as; - 1/a d[A]/dt = –1/b d[B]/dt= 1/c d[C]/dt =1/d d[D]/dt.

So, back to the question; we are given the balanced equation of,

===> 2 O3(g) --------> 3 O2(g).

Rate of disappearance of ozone,O3 is:

= -∆[O3]/ ∆t.

= -1/2 [O3]/∆t.

Where t= time and the [O3} is the concentration of ozone,O3.

Note that we have the negative sign because, ozone is been consumed/used up in the reaction.

==> The rate of the formation of oxygen is ;

= ∆[O2]/∆t.

= 1/3 ∆[O2]/∆t.
