D. Kingdom Fungi includes organisms that get energy by absorbing materials in their environment.

Explanation:

Organisms in the domain Eukarya are characterized by the possession of a well defined NUCLEUS in their cells. Kingdoms in this domain include animalia, plantae and fungi.

- Kingdom animalia contains multicellular organisms that are strictly heterotrophic i.e. cannot synthesize their own food, hence, rely on other organisms for nutrition.

- Kingdom plantae contains multicellular organisms that are capable of movement but not independently i.e. they cannot move from their fixed positions.

- Kingdom Fungi includes organisms that get energy by absorbing materials in their environment via a structure called MYCELIUM.

Answer:

0.062mol

Explanation:

Using ideal gas law as follows;

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821Latm/molK)

T = temperature (K)

Based on the information provided;

P = 152 Kpa = 152/101 = 1.50atm

V = 0.97L

n = ?

T = 12°C = 12 + 273 = 285K

Using PV = nRT

n = PV/RT

n = (1.5 × 0.97) ÷ (0.0821 × 285)

n = 1.455 ÷ 23.39

n = 0.062mol

Answer:

[tex]\boxed {\boxed {\sf P_2= 9 \ atm}}[/tex]

Explanation:

Since the temperature is held constant, we only need to focus on the volume and pressure. We will use Boyle's Law, which states the volume of a gas is inversely proportional to the pressure. The formula is:

[tex]P_1V_1=P_2V_2[/tex]

Originally, the gas had a volume of 150 milliliters and a pressure of 3.0 atmospheres. We can substitute these values into the left side of the equation.

[tex]3.0 \ atm * 150 \ mL = P_2V_2[/tex]

The original gas was compressed to a volume of 50 milliliters, but we don't know the volume.

[tex]3.0 \ atm *150 \ mL= P_2 * 50 \ mL[/tex]

Now, we need to solve for the new pressure (P₂). Multiply on the left side first.

[tex]450 \ atm*mL= P_2 * 50 \ mL[/tex]

Since we are solving for the pressure, we need to isolate the variable. It is being multiplied by 50 mL. The inverse of multiplication is division. Divide both sides by 50 mL.

[tex]\frac{450 \ atm*mL}{50 \ mL}= \frac{P_2 * 50 \ mL}{50 \ mL}[/tex]

[tex]\frac{450 \ atm*mL}{50 \ mL}= P_2[/tex]

The units of milliliters will cancel.

[tex]\frac{450 \ atm}{50 }= P_2[/tex]

[tex]9 \ atm =P_2[/tex]

The new pressure is 9 atmospheres.

Remark

Delta H is put on the reactant side of the equation. If delta H is plus the reaction goes to the right. If anything causes delta H to decrease, the reaction shifts left when delta H is originally negative.

One

Delta H is positive which means that heat has to be added before the reaction can take place. If the temperature decreases, then H2 will decrease because delta H is fighting off the temperature decrease The answer is A

Two

Pressure decreases. The side (left or right) with the most number of moles will be favored. The left side has 2 moles. The right side has 4 moles. The right side is favored. Answer: B

Answer:

A.

Explanation:

specific heat of water is immense as compared to most of other known substances. The result of this characteristic is that water heats slowly and cools slowly. In coastal region and islands, the air above lands gets heated up quickly as compared to air above water.

The impact of the specific heat of water on the planet is that air above the ocean not easily gets heated.

Specific heat is define as the amount of heat needed to increase the one unit temperature of one gram of the substance.

Specific heat of water is equal to 1 calorie and it is that much of high as water will require a lot of energy to change its temperature, and not easily gets cool or warm. Due to this water of the oceans almost have the same temperature and air above the ocean not easilt gets warmer as comapre to the air over the coastal area.

Hence, impact of the specific heat of water on the planet explained above.

Answer:

Percentage yield = 92.86%

Explanation:

We are given;

Actual yield = 3.9 grams

Theoretical yield = 4.2 grams

Formula for percent yield is;

% yield = (actual yield/theoretical yield) × 100%

Thus;

% yield = (3.9/4.2) × 100%

% yield = 92.86%

Answer:

-0.21 if you're using C as your temperature.

0.018 if you're using K as your temperature.

Explanation:

This is similar to your other question, where we'll be using the formula for specific heat capacity: Q=mcΔT

Q = heat energy (Joules)

m = mass (g)

c = specific heat capacity > What we're solving for.

ΔT = change in temperature > final temp. - initial temp.

It would be helpful to know the units so you'll know what type of problem you're dealing with and what formula you should use. But you'll usually use this formula if they mention the specific heat of an material.

Let's plug in what we know.

700= (150)(c)(32-54)

700= (150)(c)(-22)  we want to solve for c, to make it easier let's multiply the numbers on the right side so we'll have...

700=-3300c

Solve for c.

[tex]\frac{700}{-3300}[/tex] = c

-0.21 = c

This is in C though, your depending on your teacher they might want you to convert C to Kelvin (K). So Here is what it would be if it was in Kelvin.

700= (150)(c)(251)

700=37650c

A the pressure is changed to 0.8

Explanation:

Boyles gas law

The factor that the chemist changed is so that the new volume is 5.0 L is the final pressure is 0.8 atm, while temperature is kept constant.

Robert Boyle studied the relationship between pressure p and volume V of a fixed amount of gas held at a constant temperature in the mid 1600s.

Boyle discovered that the product of pressure and volume remains nearly constant. For an ideal gas, the product of pressure and volume is a constant.

Thus, the correct option is A, The final pressure is 0.8 atm, while temperature is kept constant.

Answer:

That fresh water hydrates the carbon-based lifeforms on earth. But through evaporation, and transpiration from plants leaf surfaces, it gets back into the atmosphere to feed clouds for the next rainfall. The cycling of liquid water and returning vapor creates our climate and our living environment.

Explanation:

The summary of the water cycle process is given below.

The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.

Water in different phases moves through the atmosphere (transportation). Liquid water flows across land (runoff), into the ground (infiltration and percolation), and through the ground (groundwater).

Groundwater moves into plants (plant uptake) and evaporates from plants into the atmosphere (transpiration). Solid ice and snow can turn directly into gas (sublimation). The opposite can also take place when water vapor becomes solid (deposition).

Therefore, The summary of the water cycle has been explained.

Answer:

91.4°C

Explanation:

Gay - Lussac Law => T ∝ P => T = kP => k = T/P with volume (V) and mass (n) constant.

For two different Temperature (T)-Pressure (P) conditions

k₁ = k₂ => T₁/P₁ = T₂/P₂ => T₂ = T₁(P₂/P₁)

T₁ = 55°C = (55 + 273)K = 328K      

P₁ = 965 mmHg

T₂ =  ?

P₂ = 850 mmHg

T₂ = T₁(P₂/P₁) = 328K(850 mmHg/965 mmHg) = 364K = (364 - 273)°C = 91.4°C
