Answer:
hope this helps
Explanation:
Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land. Erosion, weathering, and deposition are at work everywhere on Earth. Gravity pulls everything toward the center of Earth causing rock and other materials to move downhill.

A door is made of solid iron and this one-meter stick. How many kilojoules would it take to be to burn a hole 15 centimeters in diameter?
Answer:
The heat required, to burn a hole 15 cm in diameter through the iron door is 34,370.050 kJ
Explanation:
The information given on the door are;
The thickness of the door, t = One-meter
The diameter of the hole to be burnt out, d = 15 cm = 0.15 m
The latent heat of fusion of iron, [tex]H_f[/tex] = 247 kJ/kg
The density of iron, ρ = 7.874 g/cm³ = 7874 kg/m³
The volume of the iron to be melted off, V = π·d²/4 × t
∴ V = (π × 0.15²/4) × 1 ≈ 0.01767145867
The volume of the iron to be melted off, V ≈ 0.01767145867 m³
The mass of the iron to be melted off, m = ρ × V
∴ m = 7874 kg/m³ × 0.01767145867 m³ ≈ 139.145066 kg
The mass of the iron to be melted off, m ≈ 139.15 kg
The heat required, to melt the mass of iron at the melting point temperature and burn a hole 15 cm in diameter, ΔH, is given as follows;
ΔH = [tex]H_f[/tex] × m
∴ ΔH = 139.15 kg × 247 kJ/kg = 34,370,050 J = 34,370.050 kJ
The heat required, to burn a hole 15 cm in diameter through the iron door ΔH = 34,370.050 kJ.

What is the purpose of a buffer?
Answer: A buffer solution is a solution made to prevent the pH level of something from changing when you add a base or an acid to it. For example, if you put a buffer solution in a pool, and then you put chlorine in it, the chlorine's effect on the PH level will be suppressed.
The half life of tritium is 12.3 years. How much sample will remain if you start with 425g of tritium that is found after 4 half lives?
Answer:
26.56g
Explanation:
The half life of an isotope decay is the time transcurred when the initial amount of the isotope decays to the half of its amount.
For the problem, when 1 half life transcur, the sample has a mass of:
425g / 2 = 212.5g
When 2 half lives transcur:
212.5g / 2 = 106.25g
3 half lives:
106.25/2 = 53.13g
And the amount that is found after 4 half lives is:
53.13/2 =

A sample of sulfur dioxide occupies a volume of 6052 mL at 352 K and 892 mm Hg. What volume will the sulfur dioxide occupy at STP?
Answer:
5511.99 mL
Explanation:
Given data
Volume V1= 6052 mL
Temperature T1= 352K
Pressure P1= 892 mm Hg
At STP the parameters of gas are
Temperature T2= 273.15 K
Pressure P2= 760 mmHg
Applying the gas equation
P1V1/T1= P2V2/T2
Substitute to find V2 we have
892*6052/352= 760*V2/273.15
5398384/352= 760*V2/273.15
15336.31= 760*V2/273.15
Cross multiply
15336.31*273.15= 760*V2
4189113.0765= 760*V2
4189113.0765/760= V2
V2= 5511.99 mL
Hence the volume at STP is 5511.99 mL
In order to expand agriculture and urban areas to meet increased demand for growing populations, water supplies often have to be diverted. In three to five sentences, construct a potential chain of consequences for what could happen when water is diverted from large bodies like lakes and rivers
Answer:
Decrease occur in the amount and flow of water bodies.
Explanation:
There is decrease in the amount and flow of water from water bodies such as rivers and lakes etc occur when the river is diverted from large water bodies because the water flows to the diverted sides and decrease occurs in the amount of water in the rivers and lakes. Those regions from where this river passes can also be negatively affected due to low amount of water they receives for their daily needs or for cultivation of crops so we can say that this diversion has adverse effect on other populations.
What is the mass of Neon in a sign when the gas tubes have a total volume of 166 mL?
If there are 3 moles of gas A, 4 moles of gas b and 5 moles of gas c I'm a mixture of gases and the pressure A is found to be 2.5 atm, what is the total pressure of the sample of gases
Answer:
Total pressure = 10 atm
Explanation:
The excersise can help to understant the concept of mole fraction
Mole fraction is defined as:
moles of gas / Total moles = pressure of that gas / Total pressure
Both can be summed.
Sum of moles of each gas in the mixture = Total moles
Sum of pressures of each gas in the mixture = Total pressure
Those, are laws for gases.
Total moles: 3 mol of gas A + 4 moles of gas B + 5 moles of C
= 12 total moles
Pressure of A is 2.5 atm.
We replace data at the mole fraction relation
moles of A / total moles = Pressure of A / Total pressure
3 moles / 12 moles = 2.5 atm / Total pressure
Total pressure = 2.5 atm / (3mol/12mol)
Total pressure = 10 atm
Suppose Earth was tilted much less on its axis. What effect would this have on the planet? Please help me !
Answer:
If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.
Explanation:
If a planet tilts more, it leads to colder winters and warmer summers. However, if a planet tilts less, it leads to less severe seasons that is and milder winters and cooler summers.
If Earth was tilted much less on its axis, it would lead to minor changes in precipitation and temperatures as Earth moves slightly towards and away from the sun.

Explanation: Explanation:
Molarity is number of moles of solute divided by number of litres of solution.
M

V
Rearrange for V to give
V
=
n
M
Number of moles of KCl is the mass divided by the molar mass of KCl which is 75.5 g/mol, so (5/75.5) = 0.0667 moles.
Now plug in the numbers:
V

In this activity, you will be observing a reaction where copper and silver nitrate react to form copper (II) nitrate and silver.
What are the products of this reaction?
Answer:
Copper(II) nitrate and silver
Explanation:
2AgNO₃(aq ) + Cu (s) --> Cu(NO₃)₂(aq ) + 2Ag(s)
This can be called a redox reaction because silver nitrate is reduced and copper is oxidized. This can also be called a single replacement reaction because copper replaces silver in the substance silver nitrate.

How many mole ratios can be written for a chemical reaction involving four substances?
Answer:
12 and 20 moles ratios, respectively.
Explanation:
Note that the number of mole ratios you can write for a chemical reaction involving a total of n substances is (n)(n–1). Thus, for reactions involving four and five substances, you can write 12 and 20 moles ratios, respectively.

If I add 25 mL of water to 125 mL of a 0.15 M NaOH solution, what will the molarity of the diluted solution be? (convert mL to L and round answer to 3 decimals)
Answer:
0.75 M
Explanation:
M1 = 0.15 M
V1 = 125 mL or 0.125 L
M2 = Y
V2 = 25 mL or 0.025 L
0.15 M x 0.125 mL = Y x 0.025 L
Y = 0.15 M x 0.125 mL / 0.025 L
Cancel out the mL
Y = 0.01875M / 0.025 L
Y = 0.75M
Answer:
0.125 M
Explanation:
M₁V₁ = M₂V₂
125 mL / 1000 = 0.125 L = V₁
25 + 125 = 150 mL / 1000 = 0.150 L = V₂
0.15 M = M₁
M₁ × V₁ / V₂ = M₂
(0.15) × (0.125) / (0.150) = 0.125 M
0.125 M is the answer
