what is difference between asexual or sexual reproduction ​

Answer:

I think it can dissolve 80.0 grams

P2 = 54.6 kPa

Explanation:

Given:

V1 = 10.0 L. V2 = 50.0 L

P1 = 273 kPa. P2 = ?

We can use Boyle's law to solve this problem.

P1V1 = P2V2

Solving for P2,

P2 = (V1/V2)P1

= (10.0 L/50.0 L)(273 kPa)

= 54.6 kPa

Answer:

D . It describes a compound being broken down into the elements from which it was formed.

Explanation:

A compound consists of two or more elements chemically combined together in a chemical reaction. The compound carbon monoxide is represented by the chemical symbol, CO. This means that it contains 1 atom of the carbon element and 1 atom of the Oxygen element.

This compound is formed when carbon is directly oxidized in a limited supply of oxygen. In the above reaction, this compound is disintegrated into its individual components, namely, carbon and oxygen.

Answer:

The respiratory system is the network of organs and tissues that help you breathe. basically your airways, lungs, and blood vessels so you quite literally need these to survive I mean your muscles need oxygen to function and your brain needs oxygen to function so without your respiratory system you wouldn't be able to move much and you would quickly pass out and die from the lack of oxygen to your brain there are other body processes that need oxygen as well but these are just two examples.

Answer: Soils are formed through the interaction of five major factors: time, climate, parent material, topography and relief, and organisms.

Soil structure affects plant growth in many, often surprising, ways. The most obvious effects are on root growth, which is strongly inhibited by hard soil, and which in turn influences the ability of the root system to extract adequate water and nutrients from the soil.

Explanation:

Step 1: Calculate the amount of sodium hydroxide in moles

Volume of sodium hydroxide solution = 25.0 ÷ 1,000 = 0.0250 dm3

Rearrange:

Concentration in mol/dm3 =

Amount of solutein mol = concentration in mol/dm3 × volume in dm3

Amount of sodium hydroxide = 0.100 × 0.0250

= 0.00250 mol

Step 2: Find the amount of hydrochloric acid in moles

The balanced equation is: NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)

So the mole ratio NaOH:HCl is 1:1

Therefore 0.00250 mol of NaOH reacts with 0.00250 mol of HCl

Step 3: Calculate the concentration of hydrochloric acid in mol/dm3

Volume of hydrochloric acid = 20.00 ÷ 1000 = 0.0200 dm3

Concentration in mol/dm3 =

Concentration in mol/dm3 =

= 0.125 mol/dm3

Step 4: Calculate the concentration of hydrochloric acid in g/dm3

Relative formula mass of HCl = 1 + 35.5 = 36.5

Mass = relative formula mass × amount

Mass of HCl = 36.5 × 0.125

= 4.56 g

So concentration = 4.56 g/dm3

Answer:

amount of gas and pressure

Answer:

100 L

Explanation:

Use Boyle's Law, p1v1 = p2v2.

p1 = 4 atm

v1 = 50L

p2 = 2 atm

v2 = ?

p1v1 = p2v2

(4 atm) (50L) = (2 atm) (v2)

v2 = (4 atm)(50L) / (2 atm) = 100 L

Explanation:

It's (D), nuclear fission................

Answer:

When a saturated solution at a high temperature is cooled, why is the solution separated as a solid? When a saturated solution at a high temperature is cooled, inter molecular space between the molecules of the solution decreases. As a result, no more solute can remain in a solution separating out as a solid crystal.

Answer:

2.04 moles

Explanation:

Since the ratio of Na2O to NaOH is 1:2, you multiply the number of moles by 2, equaling 2.04 moles.

It's ammonia (NH3).....

Answer:

A molecule with one lone pair and three bond pair

- Ammonia

Answer:

Explanation:

The new volume can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we're finding the new volume we have

[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]

First convert 745 mmHg to atm

760 mmHg = 1 atm

745 mmHg = 745/760 = 0.98 atm

We have

[tex]V_2 = \frac{500 \times 0.98}{1.8} \\ = 272.222...[/tex]

We have the final answer as

Hope this helps you

Extinct

Explanation:

Extinct volcanos are not expected to erupt, and have not erupted in a very long time.

Answer:

All of these answers are correct.

Explanation:

They are all correct because producers make their food(energy) through photosynthesis, they provide food to herbivores and therefore the rest of the food chain, and without them, the food chain would collapse and all the consumers would starve.

Frost refers to solid ice that condenses and forms on surfaces like grass or windows.

Frost refers to a deposit of small white ice crystals formed on solid surfaces when the temperature falls below freezing temperature.

Frost forms when the temperature of the atmosphere is below freezing i.e. < 0°C.

Therefore, frost refers to solid ice that condenses and forms on surfaces like grass or windows.

Answer:

R = 40 ohms

Explanation:

Given that,

The voltage of outlet, V = 120 V

Current flowing through the device, I = 3 A

We need to find the Resistance rating of  the power cord. Let the resistance is R. We know that,

Ohm's law, V = IR

Put all the values,

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{120}{3}\\\\R=40\ \Omega[/tex]

So, the resistance rating of the power cord is equal to 40 ohms.

Answer:

CATION

Explanation:

If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion. If it loses an electron, it becomes positively charged and is known as a cation.

Answer: The molar mass of the gas is 9.878 g/mol.

Explanation:

According to Graham's law, the rate of diffusion is inversely proportional to square root of molar mass of gas.

[tex]Rate = \frac{1}{\sqrt{M}}[/tex]

where,

M = molar mass of gas

As given gas diffuses 1/7 times faster than hydrogen gas. So, its molar mass is calculated as follows.

[tex]\frac{R_{1}}{R_{2}} = \sqrt{\frac{M_{2}}{M_{1}}}\\[/tex]

where,

[tex]M_{1}[/tex] = molar mass of hydrogen gas

[tex]M_{2}[/tex] = molar mass of another given gas

[tex]R_{1}[/tex] = rate of diffusion of hydrogen

[tex]R_{2}[/tex] = rate of diffusion of another given gas = [tex]\frac{1}{7}R_{1}[/tex]

Substitute the values into above formula as follows.

[tex]\frac{R_{1}}{R_{2}} = \sqrt{\frac{M_{2}}{M_{1}}}\\\frac{R_{1}}{\frac{1}{7}R_{1}} = \sqrt{\frac{M_{2}}{2}}\\7 \times 1.414 = M_{2}\\M_{2} = 9.878 g/mol[/tex]

Thus, we can conclude that the molar mass of the gas is 9.878 g/mol.
