laurenercsp6fpli  I'm about done with your foolishness!!!  NOW STOP!!!

Answer:

P = 1.29 atm

Explanation:

Given data:

Volume of cylinder= 29.0 L

Mass of oxygen gas = 45.5 g

Temperature = 325 K

Pressure of gas = ?

Solution:

First of all we will calculate the number of moles of oxygen:

Number of moles = mass/molar mass

Number of moles = 45.5 g/ 32 g/mol

Number of moles = 1.4 mol

Pressure of oxygen:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K  

T = temperature in kelvin

P ×29.0 L = 1.4 mol × 0.0821 atm.L/ mol.K   × 325 K

P = 37.36 atm. L / 29.0 L

P = 1.29 atm

Answer:

B wind blowing away sediment

Explanation:

Erosion is the process whereby soil, nutrients, particles are transported away from one place to another via agents like water and wind. Generally, erosion exercises its effect on the surface of the soil.

Since erosion can occur as a result of action of water or wind on the surface of the Earth, "wind blowing away sediment" is an example of erosion among the other options listed in the question.

Answer:A=1 B= 3 C=2

Explanation: if you put a 2 where C is then the amount will then change to P4O6. so therefore keeping the P4 on the left side the same will keep that same amount & putting a 3 with the O2 on the left will increase the amount for it to be equal on both sides.

hope that makes sense sorry!

d) 22.1 moles of sulfur

Math

Pre-Algebra

Order of Operations: BPEMDAS

Chemistry

Stoichiometry

Step 1: Define

707 g S (Sulfur)

Step 2: Identify Conversions

Molar Mass of S - 32.07 g/mol

Step 3: Convert

Step 4: Round

Our closest answer is d) 22.1 moles of sulfur

This is due to dividing different rounded values.

Answer:

[tex]\boxed {\boxed {\sf D. \ 22.1 \ moles \ of \ sulfur}}[/tex]

Explanation:

To convert from moles to grams, we must use the molar mass. This can be found on the Periodic Table.

We are given a sample of sulfur. Look for the symbol S on the table.

This tells us the mass of 1 mole of sulfur. Use this molar mass as a ratio.

[tex]\frac{32.07 \ g \ S}{1 \ mol \ S }[/tex]

Multiply by the given number of grams (707).

[tex]707 \ g \ S *\frac{32.07 \ g \ S}{1 \ mol \ S }[/tex]

Flip the fraction so the grams of sulfur will cancel out.

[tex]707 \ g \ S *\frac{ 1 \ mol \ S }{32.07 \ g \ S}[/tex]

[tex]707 *\frac{ 1 \ mol \ S }{32.07 }[/tex]

[tex]\frac{ 707 \ mol \ S }{32.07 }[/tex]

[tex]22.0455254 \ mol \ S[/tex]

The number we caluclated is the closest to answer choice D: 22.1 moles of sulfur

because gametes are sexual reproducing cells, like sperm and egg cells are gametes. and those make up 50% of you

To solve this we must be knowing each and every concept related to gamete. Therefore, 50% of a mammal’s genetic material comes from each gamete. The correct option is option D.

Sex cells are another frequent name for gametes. The fundamental name for them is "reproductive cells," and they are a component of human reproductive system.

These gametes are indeed the ones that aid in sexual reproduction and they are charge of creating the zygote, a whole new cell that is known as a zygote. These cells are haploid cells, in which each and every gamete typically carries a unique version of the chromosomes. 50% of a mammal’s genetic material comes from each gamete.

Therefore, 50% of a mammal’s genetic material comes from each gamete. The correct option is option D.

one star

In our solar system, there is only one star that we know of – the sun! Our solar system is very unique in that is only has one star. Most other solar systems have at least two stars. These are called binary systems.

Explanation:

[tex]\huge\purple{Hi!}[/tex]

Some estimates peg the Milky Way's star mass as having 100 billion "solar masses," or 100 billion times the mass of the sun. Averaging out the types of stars within our galaxy, this would produce an answer of about 100 billion stars in the galaxy. This is subject to change, however, depending on how many stars are bigger and smaller than our own sun. Also, other estimates say the Milky Way could have 200 billion stars or more.

2.168 L of air will leave the container as it warms

Given

V₁=2.05 L

T₁ = 5 + 273 = 278 K

T₂ = 21 + 273 = 294 K

Required

Volume of air

Solution

Charles's Law  

When the gas pressure is kept constant, the gas volume is proportional to the temperature  

[tex]\tt \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}[/tex]

Input the value :

V₂=(V₁.T₂)/T₁

V₂=(2.05 x 294)/278

V₂=2.168 L

Answer:

V₂  = 1866.32 mL

Explanation:

Given data:

Initial temperature = 27.8°C (27 + 273.15 K = 300.15 k)

Initial volume = 1500 mL

Final volume = ?

Final temperature = 100.0°C (100.0 + 273.15 K = 373.15 K)

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

1500 mL / 300.15 k = V₂ / 373.15 K

V₂  = 1500 mL× 373.15 K/ 300.15 k

V₂  = 560175 mL. K /300.15 k

V₂  = 1866.32 mL

The reason why wind blows is it is because of the warm air...weighs less less than cold air, which rises. After that the cool air will move in replace of the rising warm air. The movement of the air is basically what makes the wind blow.

Answer:

Center of gravity

Explanation:

Gravity always acts downward on every object on earth . Gravity multiplied by the objects mass produces a force called weight. Although the force of an objects weight acts downwards on every partial of the object , it is usually considered to act as a single force through its balance point , or center of gravity.

Answer: The half life of the sample is 60.26 years.

Explanation:

All radioactive decay reactions follow first order reaction.

The formula used to calculate the rate constant for a first order reaction follows:

[tex]k=\frac{2.303}{t}\log \frac{a}{(a-x)}[/tex]

where,

k = rate constant = ?

t = time period = 25 years

a = initial concentration of the reactant = 500 g

a - x = concentration of reactant left after time 't' = (500 - 125) = 375 g

Putting values in above equation, we get:

[tex]k=\frac{2.303}{25yrs}\log \frac{500g}{375g}\\\\k=0.0115yr^{-1}[/tex]

Now, to calculate the half life period of the reaction, we use the equation:

[tex]t_{1/2}=\frac{0.693}{k}[/tex]

where,

[tex]t_{1/2}[/tex] = half life period of the reaction = ?

k = rate constant = [tex]0.0115yr^{-1}[/tex]

Putting values in above equation, we get:

[tex]t_{1/2}=\frac{0.693}{0.0115yr^{-1}}\\\\t_{1/2}=60.26yrs[/tex]

Hence, the half life of the sample is 60.26 years.

Answer:

0.45

Explanation:

We can calculate the probability of randomly selecting one button that is not white by using the formula:

Number of non-white buttons / Total Number of buttons.

We can calculate the number of non-white buttons with the information given by the problem:

# Non-White buttons = 4 + 6 = 10

Now we calculate the probability:

10 / 22 = 0.45

The probability is 0.45, or a 45% chance.
