Answer:

Supersaturated

Explanation:

The tea has absorbed and dissolved as much sugar as it could. If there is sugar left at the bottom, it means the solution is supersaturated because it can't absorb any more.

Answer:

.00402 %

Explanation:

hydrocyanic acid (HCN) is a weak acid with a Ka of 6.17*10^-10 so you need to do a RICE table

initial concentration of HCN is .381 and initial H+ and CN- concentration is 0.

that means the equillibrium concentration of HCN will be (.381-x) and H+ and CN- will be x

put that into the formula for Ka, so it'll be Ka = x^2/(.381-x) and then use quadratic equation to solve. You'll end up getting x = 1.5 * 10^-5.

Then to find percent ionization you solve (concentration of formed ions / initial HCN)

Which will be (1.5 * 10^-5 / .381) * 100 = .00402 % making it a very weak acid <3

Answer:

So the total mass is 50 plus 150 grams the heat capacity 4.18 joules per gram per degree C. And the temperature change is 36 minus 25 and so we can calculate Delta H for the reaction that takes place.

Explanation:

Answer:

Hydrogen has 0 neutrons.

Explanation:

You can find the # of neutrons by subtracting the Atomic Mass from the Atomic number. Hydrogen is a special case in which the atom has no neutrons.

Answer:

Avogadro's Law; 15.1L

Explanation:

Boyle's Law- Pressure and volume are inversely related, so an increase in pressure= decrease in volume. We see this in the equation P1V1=P2V2.

Charle's Law- Gas expands/increases in volume when temperature increases, so they are proportional. We see this in the formula [tex]\frac{V1}{T1} = \frac{V2}{T2}[/tex].

Guy-Lussac's Law-  As temperature increases, pressure increases, so they are proportional. We see this in the formula [tex]\frac{P1}{T1} = \frac{P2}{T2}[/tex].

Avogadro's Law- There are equal amount of volume have an equal amount of moles, so they are proportional. We see this in the formula [tex]\frac{V1}{n1} = \frac{V2}{n2}[/tex].

Plugging in the values based on Avogadro's Law, we'll have:

[tex]\frac{36.5}{2.9} = \frac{V2}{1.2}[/tex]

12.6 = [tex]\frac{V2}{1.2}[/tex]

12.6 x 1.2 = V2

15.1L =V2

Answer:

6.75 sym.

Explanation:

Boyle's Law:  The pressure of a gas in an enclosed container with a flexible volume is inversely proportional to the volume occupied by the gas.

Empirically => P ∝ 1/V => P = k(1/V) => k = P·V

For any conditions of Pressure & Volume, Pressure x Volume is a constant.

Therefore, k₁ = k₂ => P₁V₁ = P₂V₂ => V₂ =  P₁V₁ / V₂

=> V₂ = (3atm)(0.450L)/(0.200L) = 6.75 atm.

Answer:

203.63 K

Explanation:

Using Charles law equation,

V1/T1 = V2/T2

Where;

V1 = initial volume (mL)

V2 = final volume (mL)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information in this question,

V1 = 675.6 mL

V2 = 410.9 mL

T1 = 61.8°C = 61.8 + 273 = 334.8K

T2 = ?

Using V1/T1 = V2/T2

675.6/334.8 = 410.9/T2

Cross multiply

675.6 × T2 = 334.8 × 410.9

675.6T2 = 137569.32

T2 = 137569.32 ÷ 675.6

T2 = 203.63 K

A)extrusion

Explanation:

The feature that causes a gap in the geologic record is called extrusion.

Sometimes magma can force itself through a crack or fault in the rock at the Earth's surface. It pours out over the Earth's surface in a volcanic eruption. This process is called extrusion. The rocks that form from extruded magma are called extrusive igneous rocks.

Direct Extrusion, Indirect Extrusion, Hydrostatic Extrusion and Lateral or Vertical Extrusion are some types of extrusion.

Lava that hardens on the surface is called an extrusion. The rock layers below an extrusion are always older than the extrusion. Beneath the surface, magma may push into bodies of rock. There, the magma cools and hardens into a mass of igneous rock called an intrusion.

Therefore, The feature that causes a gap in the geologic record is called extrusion.
