An element is defined as a substance made up of atoms with a specific number of protons.
Answer:
D (Decomposition)
Explanation:
This reaction is a decomposition reaction because one substance (NaNO3) is being separated into two substances (NaNO2 and O2). Alternatively, you could use the process of elimination. The reaction can't be single/double replacement because there's only one reactant, it can't be synthesis because substances are being broken down, not formed, and it can't be combustion because O2 is a product, not a reactant, and CO2 and H2O aren't being produced, as is common with combustion reactions.
Answer:
K = 9.4 *10^5
The reaction favor product formation
Explanation:
Equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium. Also it is defined as the ratio of the product of concentration of products to the product of concentration of reactants each term raised to power equal their stochiometric coefficients.
so, for the reaction,
- 2H₂ ₍g₎ + S₂ ₍g₎ → 2H₂S ₍g₎
The equilibrium constant can be expressed as following:
![K_{eq}=\frac{[H_2S]^2}{H_2]^2\times [S_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BH_2S%5D%5E2%7D%7BH_2%5D%5E2%5Ctimes%20%5BS_2%5D%7D)
where concentration of reactants and products is expressed in molarity Molarity=(no of moles/ Volume L)
So,
[H₂] = (0.50 mol / 1 L) = 0.50 M
[S₂] = (0.02 mol / 1 L) = 0.020 M
[H₂S] = (68.5 mol / 1 L) = 68.5 M
∴ K_{eq}=\frac{[68.5]^2}{0.50]^2\times [0.020]}=9.4*10^5
As the value of K is greater than 1, the reaction favor product formation.
Answer:
A.
Explanation:
In conclusion, an electrically neutral object is an object that has a balance of protons and electrons. In contrast, a charged object has an imbalance of protons and electrons. ... The type of charge(positive or negative) is determined by whether the protons or the electrons are in excess
