820 g Li2SO4 is dissolved into 2500 mL of solution. What is the molar concentration?
Andreas93 [3]

Molarity is defined as the moles of solute per liter of solution. M=\frac{n}{V}. Where M is molarity, n is the number of moles and V is the volume. First we must find the molar mass of Li_2SO_4 which is 109.98 g/mol

Li_2SO_4= 2 \times Li_{Ar} + S_{Ar} + 4 \times O_{Ar}\\= (2 \times 6.941 + 32.1 + 4 \times 16.0) = 109.98 g/mol

820\ g\ Li_2SO_4 \times \frac{mol}{109.98\ g}= 7.46\ mol\ Li_2SO4

Then we find the molarity using above equation

M= \frac{n}{V} = \frac{7.46 mol}{2500ml} \times\frac{1000ml}{L} = 2.98\ M

The SN1 reaction yields Entry field with incorrect answer two (number) products. This is because ______________________. Entry f
vagabundo [1.1K]

Answer:

Four substitution products are obtained. The carbocation that forms can react with either nucleophile (H2O or CH3OH) from either the top or bottom side of the molecule

Explanation:

An SN1 reaction usually involves the formation of a carbocation in the slow rate determining step. This carbocation is now attacked by a nucleophile in a subsequent fast step to give the desired product.

However, the product is obtained as a racemic mixture because the nucleophile may attack from the top or bottom of the carbocation hence both attacks are equally probable.

The attacking nucleophile in this case may be water or CH3OH

It's actually Science but I didn't find it.
fomenos

Answer:

Forces acting on an object may be balanced or unbalanced. When the forces  acting on an object have <u>equal</u> strength and act in opposite directions, they  are <u>balanced</u>. These forces cancel out one another, and the <u>motion</u> of the  object does not <u>change</u>.  When the forces acting on an object are <u>unbalanced</u>, they do not cancel out  one another. An unbalanced force acting on an object results in the object’s  motion <u>changing</u>. The object may change its <u>speed</u> (speed up or slow down), or it may change its <u>direction</u>.  <u>Friction</u> is a force that resists the motion or the tendency toward motion  between two objects in contact with each other.  <u>Gravity</u> is a force that pulls objects toward one another. For example, Earth  pulls all objects toward it.

You have dissolved 10 g sodium oxide in 200 ml water.calculate concentration of the solution
e-lub [12.9K]

Answer:

0.85 Molar Na2O

Explanation:

Determine the moles of sodium oxide, Na2O, in 10 grams by dividing by the molar mass of Na2O (61.98 g/mole).

 (10 g Na2O)/(61.98 g/mole) = 0.161 moles Na2O.

Molar is a measure of concentration.  It is defined as moles/liter.  A 1 M  solution contains 1 mole of solute per liter of solvent.  [200 ml water = 0.2 Liters water.]

In this case, we have 0.161 moles Na2O in 0.200 L of solvent.

 (0.161 moles Na2O)/(0.200 L) = 0.85 Molar Na2O

If you have nitrate and carbon oxygen what can that combine with to make
WARRIOR [948]

Answer: Gunpowder

Explanation:

Gunpowder is made by mixing potassium nitrate with two fuels (atoms that can combine with oxygen atoms and release energy), carbon (charcoal) and sulfur. The oxygen atoms leave the nitrates and move onto the carbon and sulfur atoms, releasing a buttload of energy.
