C. 3.10 g, 3.20 g, 3.23 g
I came to this conclusion because:
A. 3 g, 4 g, 5 g, well these have 10 units between (0.1, .2, etc) so they are not the closest.
B. 3.0, 4.0, 5.0 just like above, they still have 10 units between
D. 3.0, 4.0, 5.0, 6.0 these numbers, just like in the previous two, have 10 units between, making them not precise or the closest option.
C is your answer because 3.10 - 3.23 are only 2 units apart. Making them the most precise.
Answer:
The VSEPR theory stands for the valence shell electron pair repulsion theory. It is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms.
Volume of a cube is length times width times height so do 125 times 37 times 68
The pressure : 1.536 atm
<h3>Further explanation</h3>
Same container=same volume⇒the volume is constant
Gay Lussac's Law
<em>When the volume is not changed, the gas pressure in the tube is proportional to its absolute temperature </em>
![\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7BP_1%7D%7BT_1%7D%3D%5Cdfrac%7BP_2%7D%7BT_2%7D)
P₁=1 atm
T₁=20+273=293 K
T₂=450 K
the pressure :
![\tt P_2=\dfrac{P_1.T_2}{T_1}\\\\P_2=\dfrac{1\times 450}{293}=\boxed{\bold{1.536~atm}}](https://tex.z-dn.net/?f=%5Ctt%20P_2%3D%5Cdfrac%7BP_1.T_2%7D%7BT_1%7D%5C%5C%5C%5CP_2%3D%5Cdfrac%7B1%5Ctimes%20450%7D%7B293%7D%3D%5Cboxed%7B%5Cbold%7B1.536~atm%7D%7D)
I don’t know what plant were presented in your lesson. So, I did sunflowers. The tropism I used was photo tropism
