The question is~ Which is not a biomass energy source?​

Answer:

98.4 kPa

Explanation:

Step 1: Given and required data

Step 2: Calculate the total pressure of the gaseous mixture

The total pressure of the gaseous mixture (P) os equal to the sum of the partial pressures of the gases that form it.

P = pH₂O + pN₂ + pHe

P = 19.9 kPa + 53.0 kPa + 25.5 kPa = 98.4 kPa

The total pressure of the wet gas mixture is 98.4 KPa

This law states that at constant temperature, the total pressure of a mixture of gases is equal to the sum of the partial pressure exerted by each gas. Mathematically, it is expressed as

Total pressure = partial pressure of A + partial pressure of B

P = pH₂O + pN₂ + pHe

P = 19.9 + 53 + 25.5

P = 98.4 KPa

Answer:

Liquid isopropanol.

Explanation:

Liquid isopropanol will evaporate earlier than water because the boiling point of isopropanol is less than water. That liquid which have high boiling point require more heat energy for change into vapor state as compared to those liquids that has low boiling point. The isopropanol has boiling point i.e. 82.5 °C while on the other hand, water has boiling point i.e. 100 °C so we can say that isopropanol will evaporate first.

The liquid that will be the first to evaporate within 5 minutes is; Liquid Isopropanol

We have the 2 liquids as;

Liquid Isopropanol

Liquid water

Now, since we are dealing with the one that will evaporate within five minutes, we need to know their boiling points.

From online research;

Boiling point of liquid isopropanol is 82.5°C

Boiling point of liquid water is 100°C

Now, we are told that the same energy is transferred for both liquids. However, boiling point of the liquid with the lower boiling point will be achieved first and as a result will evaporate first since the next stage after boiling point is evaporation of steam.

c. Gas particles don't interact

Explanation:

Ideal gas particles do not interact with each other.

The gas molecules do not interact with each other except for colliding with each other. Gases expand to completely fill a container; they would not if they were attracted to each other. That being said, they obviously still do, as a result of Dalton's Law.

22.4 x L x mol - 1

Answer:

Explanation:

Since salt is composed of two ions Na+ and Cl- it will attract to the opposite poles of the water and form a ion-dipole bond. This will cause the phenomenon freezing point depression where as the name states it will take a lower tempertature to freeze it. So instead of freezing at 0 degrees c it will freeze at a negative 2 or so on.

The salt ions end up slowing the growth of ice as the water molecules re-freeze.

Freezing point depression can be defined as the decreasing of the freezing point of pure solvents upon the addition of different kinds of solutes.

Depression in the freezing point can be defined as a colligative property that is proportional to the molality of the solution.

As liquid water gets colder and colder, the motions of water molecules become slower and slower. When salt is added to water, the saltwater solution is composed of both water molecules and dissolved salt ions.

As a result, salt ions can easily replace some of the water molecules. Saltwater freezes more slowly than pure water due to many of the water molecules would be "crashing" into the ice's surface in pure water and are replaced by salt ions.

Therefore, the salt water will freeze at a lower temperature than the pure water.

Answer:

The cinnamon cost would be "$8.62". A further explanation is given below.

Explanation:

Cinnamon's density,

= 0.560 g/ml

On converting it into g, we get

= [tex]0.560\times 500[/tex]

= [tex]280 \ g[/tex]

Cinnamon's volume,

= 500 ml

As we know,

1 pound = 435.592 g

Now,

The cost pf cinnamon per pound will be:

=  [tex]\frac{6.98}{0.5 \ pound}[/tex]

=  [tex]13.96[/tex] ($) per pound

So,

Cinnamon's cost will be:

=  [tex]250 \ g\times \frac{1 \ pound}{435.592 \ g}\times \frac{13.96}{1 \ pound}[/tex]

=  [tex]8.62[/tex] ($)

Explanation:

Wait did I get your quiz right? Are you asking for the name? If so it's radical

Answer

7.53% 97% if you divide it you can get the answer

Explanation:

Answer:

2.1 atm

Explanation:

We are given the following variables to work with:

Initial pressure (P1): 2.5 atm

Initial temperature (T1): 320 K

Final temperature (T2): 273 K

Constant volume: 7.0 L

We are asked to find the final pressure (P2). Since volume is constant, we want to choose a gas law equation that relates initial pressure and temperature to final pressure and temperature. Gay-Lussac's law does this:

[tex]\frac{P_{1}}{T_1} =\frac{P_{2}}{T_2} \\[/tex]

We can rearrange the law algebraically to solve for [tex]P_{2}[/tex].

[tex]{P_{2}} =\frac{(T_2)(P_{1} )}{T_1} \\[/tex]

Substitute your known variables and solve:

[tex]P_2 = \frac{273K(2.5atm)}{320K} = 2.1 atm[/tex]

Answer:

[OH-] = 2 x 10^-6 M

Explanation:

Calculate pOH first: 14 - pH = pOH --> pH = 14 - 8.3 = 5.7

[OH-] = 10^-pOH = 10^-5.7 = 2 x 10^-6 M

Only one sig fig in the concentration, because the pH only had one decimal place.

Answer:

Mole

Explanation:

In solids, amount of substance is given by;

n = mass/molar mass

n will have a unit of mole

However, in liquids, amount of substance is;

n = concentration × volume

Again, n will be in mole

Thus, the SI unit that represents the amount of substance is mole

17. 50% chances of round offspring

18. 25% chances two copies of dominant allele in the genotype of offspring

Explanation:

17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.

S for square trait and s for a round trait then

    S     s

s Ss    ss

s Ss    ss

Thus, the correct answer is 50 percent as there are only two copies of ss.

18. in this question Patric and Patti both have heterozygous for the pink (P) body-color dominant over yellow (p). The chances for the true-breeding dominant genotype would be -

     P    p

P   PP  Pp

p   Pp  pp

There is only one out of four rue-breeding dominant offspring will be produced.

Answer:

The gas under pressure subjected to heat can cause the tank to explode. A scuba tank filled to capacity with compressed air at 3000 psi could just as easily go up to 3400-3500 psi if heated

Explanation:

Air molecules are free to move and as more air is added to the tank, the molecules move and collide faster which raises the temperature. Hence option D is correct.

Pressure is defined as the force applied perpendicularly to an object's surface divided by the surface area over which it is applied. The movement of the molecules and the collisions they have with one another and the vessel walls cause the pressure to build up. According to general relativity theory, pressure contributes to the mass-energy cause of gravity by making a gravitational field stronger.

The tank may blow up if the gas within was under pressure and exposed to heat. If heated, the pressure of a scuba tank filled to capacity with compressed air at 3000 psi may readily increase to 3400-3500 psi. Because air molecules are free to move, the temperature in the tank rises as more air is introduced, as the molecules move and collide more quickly.

Thus, air molecules are free to move and as more air is added to the tank, the molecules move and collide faster which raises the temperature. Hence option D is correct.
