<span>Answer:
(0.150 L) x (0.0240 M Fe{3+}) x (3 mol OH{-} / 1 mol Fe{3+}) / (1.39 M NaOH) = 0.00777 L = 7.77 mL NaOH</span>
Answer:
Option B - 2
Explanation:
In Crystal lattices, there are different types of unit cells namely;
- Hexagonal Closest Packed (HCP)
- Face Centred Cubic (FCC)
- Body Centred Cubic (BCC)
- Simple Centred Cubic (SC)
Now, each of them have a coordination number and also number of atoms per unit cell.
For this question, we are restricted to the body-centered cubic (bcc) unit cell which has a coordination number of 8 and contains 2 atoms per unit cell.
Answer:
A leaf needs carbon dioxide and water for photosynthesis. ... For carbon dioxide to enter, the stomata on the surface of the leaf must be open. As you have seen, transpiration draws water from the roots into the leaf mesophyll.
I hope this helps you :)
<u>Answer;</u>
B) water molecule has a bent shape.
<u>Explanation;</u>
- Water molecules are polar molecules because of their shape. Water molecules have one side that is positively charged due to hydrogen atom which is partially positive and the other side which is negatively charged, due to the oxygen atom.
- When two molecules get close to each other the polar forces of attraction brings them close to each other. Oxygen bonds with several hydrogen atoms in the other water molecules resulting to hydrogen bonds.
Answer:
Liters per second is 0.2 LPS
Liters per hour is 720
Explanation:
Divide the litres by the time, than multiply the time of an hour (in seconds) and than multiply the lps by time of an hour in seconds.
