Answer:
Sedimentation occurs when the suspended particles in the mixture are large enough to settle to the bottom of a vessel under their own weight. An example of this is like mud falling to the bottom of a pond, or tea leaves falling to the bottom of a cup of tea.
Explanation:
<span>Li3P=ionic </span>
<span>PH3=Covalent </span>
<span>C2H6=Covalent </span>
<span>IBr=Covalent</span>
The number in Kg of oxygen that are present in the room is
403.1209 kg
<em><u>calculation</u></em>
mass=density x volume
density = 0.001429 g/ cm³
volume =775 cm x 1400 cm x 260 cm =2.821 x10^8 cm³
mass =0.001429 g/cm³ x( 2.8 x 10^8 cm³) =403120.9 grams
convert g to Kg
that is 1 kg = 1000 g
? kg =403120.9 g
by cross multiplication
=[(403120.9 g x 1 kg) /1000 g] =403.1209 kg
Answer:
8.15 L I2
Explanation:
<u>So, I have the balanced equation of</u>: 2CuBr2 +4KI → 2CuI + 4KBr + I2
<u>Now, we do</u>:
241.6g / 1 mol KI / 1 mol I2 / 22.4 L
--------------------------------------------------------- = 8.15 L I2
/ 166g KI / 4 mol KI / 1 mol I2
Hope this helps! ^u^
The accuracy of an indicator’s end point depends on the relative strength of the metal–indicator complex and the metal.<span>Unfortunately, because the indicator is a weak acid, the color of the uncomplexed indicator also changes with pH.</span>
