The N from NH3 forms a coordinate
covalent bond with the metal iron as in this case. The iron itself is at the "center" of the ligate complex ion. Since the net ionic charge is at 2+, it can be said that there is one pair of unpaired electrons for <span>[fe(nh3)6]2+.</span>
Answer:
This question is incomplete. The completed question is below
Procedure
1. Read and complete a lab safety form.
2. Place about 50 copper pellets into a plastic petri dish. Place the cover on the dish, and secure it with tape.
3. Hold the dish by the edges. Gently vibrate the dish from side to side no more than 1–2 mm. Observe the pellets. Record your observations in your Science Journal.
4. Repeat step 3, vibrating the dish less than 1 cm from side to side.
5. Repeat step 3, vibrating the dish 3–4 cm from side to side.
if the pellets represent particles in matter, what do you think the shaking represents?
Explanation:
This procedure seeks to illustrate the "properties" of particles in matter. The shaking of the pellets represents the movement of the particles of matter (which occurs in liquids and gases). This is because the movement of particles in a liquid and gaseous state freely moves around (reason the petri-dish was vibrated so the pellet particles which serve as the liquid/gaseous particles can move freely).
NOTE: The particles in a solid have a highly restricted movement (or no movement) because of the compact nature of the particles within the solid.
(1.1232 * 10⁵) (6.022 * 10¹⁷)
Now, multiply simple numbers together and exponentials, together:
= 1.1232 * 6.022 * 10⁵ * 10¹⁷
= 6.763 * 10²²
In short, Your Answer would be 6.763 * 10²²
Hope this helps!
Pneumonia is caused when an H3 is positive to any form so therefore the answer would be the element of a pneumonia will be a positive 6392
The number of milliliters of the solution that you need to give to the patient is calculated as follows
32mg is in 1 ml of the solution
what about 320mg
=( 320mg x 1 ml) /32mg= 10ml
