This is a decomposition reaction.
Silver has a charge of plus one, and oxygen has a charge of minus two. So this equation is not balanced. 
The first part is right. The two should be a subscript. The second part is not right and you should add the 2 to the Silver instead of the oxygen.

Calculate the mass of water produced when 9.57 g of butane reacts with excess oxygen.
irinina [24]

Answer:

14.9 g

Explanation:

Step 1: Write the balanced equation

C₄H₁₀ + 6.5 O₂ ⇒ 4 CO₂ + 5 H₂O

Step 2: Calculate the moles corresponding to 9.57 g of C₄H₁₀

The molar mass of C₄H₁₀ is 58.12 g/mol.

9.57 g × 1 mol/58.12 g = 0.165 mol

Step 3: Calculate the moles of H₂O produced from 0.165 moles of C₄H₁₀

0.165 mol C₄H₁₀ × 5 mol H₂O/1 mol C₄H₁₀ = 0.825 mol H₂O

Step 4: Calculate the mass corresponding to 0.825 mol of H₂O

The molar mass of H₂O is 18.02 g/mol.

0.825 mol × 18.02 g/mol = 14.9 g

Calculate the concentration of OH-in a solution that has a concentration of H+ = 8.1 x 10^−6 M at 25°C. Multiply the answer you
Nat2105 [25]

Answer:

The answer is 12.35

Explanation:

From the question we are given that the concentration of H^{+} is 8.1 * 18^{-6}M

 Generally The rate equation is given as

                                                           K_{w} = [H^{+} ][OH^{-} ]

and K_{w} the rate constant has a value 1 * 10^{-14}

     Substituting and making [OH^{-}] the subject we have

                                                 [OH^{-} ] = \frac{1 * 10^{-14}}{[H^{+}]} = \frac{1 * 10^{-14}}{8.1 *10^{-6}} =1.235 * 10^{-9}

                                                  [OH ^ {-}] = 1.235 * 10^{-9}M

                            Multiply the value by 10^{10} as instructed from the question we have  

                       Answer =   1.235 * 10 ^{-9} * 10^{10} = 12.35

Hence the answer in 2 decimal places is 12.35
