When vinegar and baking soda are mixed, a new chemical called carbonic acid is made. This carbonic acid immediately decomposes into carbon dioxide gas. When you mix the vinegar and baking soda, it's the carbon dioxide gas that makes the bubbles.
Answer:step 1 is unimolecular and step 2 is bimolecular
Explanation:
Answer:
[Ba(OH)₂] = 0.21 M
Explanation:
Molarity is a sort of concentration for solute that determines the moles of solute contained in 1 L of solution (mol/L).
Solution's volume = 45.6 mL
We convert the volume from mL to L → 45.6 mL . 1 L/1000 mL = 0.0456L
Our solute: Ba(OH)₂
We convert the mass of solute to moles → 1.68 g / 171.33 g/mol =
0.00980 moles
Molarity → mol/L → 0.0980 moles / 0.0456L = 0.21 M
This problem requires our calculation to undergo the dimensional analysis approach. In this approach, you disregard the actual quantity and focus on the units of measurement. This helps us know the units of our final answer.
First, let's ignore 16. Let's focus on converting the units kPa-mm³/s to mJ/s. The unit kPa stands for kiloPascals which is 1000 times greater than 1 Pa. The unit mJ, on the other hand, stands for millijoules, which is 1000 times lesser than Joules. The relationship between the two is that, Joules = Pa × m³. But since we want our final answer to be mJ, that would be equal to Pa×mm³. Since the original unit already contains mm³, all we have to do is convert kPa to Pa.
16 kPa-mm³/s * (1000 Pa/1 kPa) = 16,000 Pa-mm³/s
Since Pa-mm³ is equal to mJ, the final conversion yields to 16,000 Pa-mm³/s.
