A neutralization reaction is a fundamental type of chemical reaction where an acid and a base react with each other to produce a salt and water. The key idea here is neutralization—the acid and the base effectively cancel out or neutralize each other's properties (like acidity and basicity). The general form of a neutralization reaction is: $$\text{Acid} + \text{Base} \rightarrow \text{Salt} + \text{Water}$$ The reaction is essentially the combination of hydrogen ions ($\text{H}^+$) from the acid and hydroxide ions ($\text{OH}^-$) from the base to form water ($\text{H}_2\text{O}$). *** Example: A classic example is the reaction between Hydrochloric Acid ($\text{HCl}$) and Sodium Hydroxide ($\text{NaOH}$). $$\text{HCl (Acid)} + \text{NaOH (Base)} \rightarrow \text{NaCl (Salt)} + \text{H}_2\text{O (Water)}$$ * $\text{HCl}$ is a strong acid. * $\text{NaOH}$ is a strong base. * $\text{NaCl}$ is table salt, which is a neutral salt. * $\text{H}_2\text{O}$ is water. This reaction is commonly used in labs during a process called titration to determine the concentration of an unknown acid or base!

Changing the pay date in QuickBooks Online (QBO) is usually quite straightforward, assuming you're using the integrated Payroll service. The exact steps can vary slightly depending on whether you're trying to adjust a single paycheck date or change the regular pay schedule for your employees. ### To change the pay date for a single, upcoming paycheck: 1. Go to the Payroll menu in QBO. 2. Click on Employees (or Workers) and then Run Payroll. 3. In the "Run Payroll" flow, you will see a section where you can select the Pay Date (and often the Pay Period End Date). 4. Simply click on the date field and select the new date you want for that specific payroll run. 5. Continue through the review and submission process as usual. ### To permanently change the regular pay schedule: If you want all future payrolls to be on a new day (e.g., from Tuesday to Friday), you'll need to edit the pay schedule itself: 1. Go to the Settings gear icon (⚙️) and select Payroll Settings. 2. Find the Pay Schedules section (or similar name). 3. Select the schedule you need to modify. 4. Edit the Next Pay Date and the Pay Frequency/Pay Period End Date as needed. 5. Save your changes. Make sure to do this well in advance of your next payroll so there's no confusion for you or your employees!
