Answer:
pro
Explanation:
c3h8 is propane
3 carbons makes it PROpane
the ANE come from all single bonds
Answer:
· A chemical reaction is a process generally characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds. There are several different types of chemical reactions and more than one way of classifying them.
Explanation:
Cl₂O + H₂O ⇄ 2HClO
K = [HClO]²/[Cl₂O][H₂O]
K = (0,023)²/(0,077×0,077)
K = 0,000529/0,005929
<u>K</u><span><u> </u></span><u>≈</u><span><u> </u></span><u>0,0892

Answer:
d. changing temperature
Explanation:
The thermodynamic equilibrium constant K is defined as a quantity characterizing the equilibrium of a chemical reaction. For a reaction where concentrations are in equilibrium:
aA + bB ⇄ cC + dD
The equilibrium constant is:
![k = \frac{[C]^c[D]^d}{[A]^a[B]^b}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B%5BC%5D%5Ec%5BD%5D%5Ed%7D%7B%5BA%5D%5Ea%5BB%5D%5Eb%7D)
Thus, the equilibrium constant will change if:
a. Varying the initial concentration of reactants
. FALSE. The k constant doesn't depend of initial concentrations but concentration in equilibrium does.
b. Adding other substances that do not react with any of thespecies involved in the equilibrium
. FALSE. The equilibrium constant just depends of substances that are involved in the equilibrium
c. Varying the initial concentration of products
. FALSE. Again, equilibrium constant doesn't depend of initial concentrations.
d. Changing temperature
. <em>TRUE. </em>As a thermodynamic constant, k depends of temperature thus:

e. Changing the volume of the reaction vessel. FALSE. The changing in the volume of the reaction vessel will change just the initial concentrations of the reactants.
I hope it helps!
Answer:
Lithium oxide, Li₂O.
Explanation:
Hello!
In this case, according to the given amounts, it is possible to write down the chemical reaction as shown below:
Which means that the metallic oxide has the following formula: M₂O. Next, we can set up the following proportional factors according to the chemical reaction:
Thus, we perform the operations in order to obtain:
So we solve for x as shown below:
Whose molar mass corresponds to lithium, and therefore, the metallic oxide is lithium oxide, Li₂O.
Best regards!
