The mixture can be separated into three separate components by using a centrifuge and a separating funnel.
A centrifuge is used to separate a solid that is held in suspension by a liquid. In this case a solid dissolved in water. In contrast, a separating funnel is used to separate two immiscible liquids.
-First take the flask containing the two immiscible liquids and pour contents in to a closed separating funnel.
- The most dense liquid will settle at the bottom, then open the separating funnel valve to collect contents of dense liquid into a flask.
- The remaining liquid on the separating funnel can be collected in a different flask.
-Now take the liquid that is a solution of a solid in water and pour in a test tube. Place the contents in a centrifuge.
- Centrifuge at high speed until the solid sinks to the bottom of the test tube, then decant the liquid into a flask and the solid remains in the test tube
Answer:
0.86
Explanation:
1mol of Zn has mass of 65.39g.The amount of Zn is 2.5g65.39g/mol=0.038mol.
The amount of H2 produced is the same as the amount of Zn consumed (0.038mol).
1mol of ideal gas will occupy 22.4L at STP.
The H2 will occupy 0.038mol×22.4L/mol=0.86L
.
Answer:
0.023 mol/(L*s).
Explanation:
Equation of the reaction:
2 D(g) + 3 E(g) + F(g) => 2 G(g) + H(g)
Using stoichiometry, 2 moles of D reacts with 3 moles of E and 1 mole of F to give the above products.
1 mole of D will react with 3/2 moles of E.
Delta[D]/delta t = 0.15 mol/L.s
Delta[E]/delta t = (3/2) * 0.15 =
= 0.023 mol/(L*s).
<span>Hydrogen isn't classified as an alkali metal because it exhibits several properties that are not found in the alkali metal group, including the tendency to be found as a diatomic molecule, a tendency to form weak bonds with other bound hydrogen atoms nearby, weak electromagnetism, a low activity series placement, and the tendency to be found as a gas. Because of all this, it's impossible to classify it with any group, although it does seem to be closest to nonmetals.</span>
What are the elements so i can help?????
