The answer would be 1.15 kilojoules. ope this helps.
Choose all options that apply . Which of the following are steps necessary to ensure patient safety ? a) Make sure that the medication is dispensed in the same units in which it was prescribed. b ) Review any calculation questions with the pharmacist . Check to see if there's a better medication for the patient's problem. d) Dispense an extra dose to save the patient from having to return in case of loss or damage to one of the doses. Oe ) Compare the label on the medication with the order from the physician .
ANSWER- B
Atomic emission spectra are produced when excited electrons return to the ground state. The emitted light corresponds to energies of the specific electrons.
Answer:
All the amounts of reactants and products are:
KBr
11.0g (given)
0.0924 mol
Cl₂
0.0462 mol
3.28g
KCl
0.0924 mol
6.89 g
Br₂
0.0462 mol
7.39 g
Explanation:
<u>1. Balanced chemical equation (given)</u>

<u>2. Mole ratios</u>



<u />
<u>3. Molar masses</u>
- Molar mass Cl₂: 70.906g/mol
- Molar mass KBr: 119.002 g/mol
- Molar mass KCl: 74.5513 g/mol
- Molar mass KBr: 159.808 g/mol
<u>4. Convert 11 grams of potassium bromide to moles:</u>
- #moles = mass in grams / molar mass
- #mol KBr = 11g / 119.002g/mol = 0.092435mol KBr
<u>5. Use the mole ratios to find the amounts of Cl₂, KCl, and Br₂</u>
a) Cl₂


b) KCl


c) Br₂


The final calculations are rounded to 3 sginificant figures.
