<u>Answer: </u>The chemical formula for Palladium(IV) sulfate is
<u>Explanation:</u>
Palladium is the 46th element of the periodic table which has an oxidation state of +4 (because it is a metal and will form positive ion) and sulfate is the polyatomic ion having a charge of -2 with formula
So, to write the formula of the compound, we do criss cross method in which oxidation state of each element or ion is given to the other combining atom which results into the formation of a neutral compound.
The chemical formula of the compound is

The rate of a reaction is not affected by C) the magnitude of the equilibrium constant.
<h3>What is the rate of a reaction?</h3>
The rate of a reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.
Let's consider which of the following factors affect the rate of a reaction.
- A) the concentration of the reactants. YES. The relationship between the concentrations of the reactants and the reaction rate depends on the reaction orders.
- B) presence of a catalyst. YES. Positive catalysts increase the reaction rate whereas negative catalysts decrease it.
- C) the magnitude of the equilibrium constant. NO. The equilibrium constant does not affect the reaction rate.
- D) the temperature of the reaction. YES. Usually, the higher the temperature, the faster the reaction.
- E) the surface area of the solid reactants. YES. The more surface area exposed to react, the faster the reaction.
The rate of a reaction is not affected by C) the magnitude of the equilibrium constant.

The Chemical change that occurred was the vinegar and baking soda creating gas or air bubbles. While the vinegar and baking soda are losing their mass, the gas created from the chemical reaction is filling in those gaps so the mass of the structure is the same before and after the experiment was conducted.
Answer: What is the mass of disulfur pentoxide (S2O5)?
Explanation:144.14g/mol
Answer:
0.019 g.
Explanation:
- Firstly, we need to find the no. of moles of oxygen gas:
- We can use the general law of ideal gas: <em>PV = nRT.
</em>
where, P is the pressure of the gas in atm (P = 1.02 atm).
V is the volume of the gas in L (V = 15.0 L).
n is the no. of moles of the gas in mol (n = ??? mol).
R is the general gas constant (R = 0.0821 L.atm/mol.K),
T is the temperature of the gas in K (T = 28°C + 273 = 301.0 K).
∴ n = PV/RT = (1.02 atm)(15.0 L)/(0.0821 L.atm/mol.K)(301.0 K) = 0.62 mol.
- To find the mass of oxygen gas, we have:
<em>no. of moles = mass/molar mass.</em>
<em></em>
∴ mass of oxygen = (no. of moles)(molar mass) = (0.62 mol)(32.0 g/mol) = 0.019 g.
