Answer:

It's big brain time

Explanation:

Weathering is the process of breaking rocks into sediment while erosion is the process that wears away this sediment and other materials and moves them from one location to another. Agents of erosion include gravity, glaciers, wind, and water. Erosion only occurs when these agents have enough energy. The moment agents of erosion lose their energy and momentum they deposit their load. This process is known as deposition. The load is what the agent is carrying. As agents of weathering lose their energy, the heavier sediment is dropped. As the energy is lost, gravel, then sand, then silt, and then clay are deposited, due to their respective masses.

Mass movement, sometimes referred to as mass wasting, is what we call the movement of surface material due to gravity, water, wind, and ice. There are five main types of mass movements: falls, creep, flows, slides, and slump.

A flexible container at an initial volume of 6.13 L contains 6.51 mol of gas. More gas is then added to the container until it r

aivan3 [116]

Answer:

the final mole of the flexible container = 12.92 moles

Explanation:

Given that :

initial volume of a flexible container = 6.13 L

initial mole of a flexible container = 6.51 mol

final volume of a flexible container = 18.3 L

final mole of a flexible container = ???

Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.

Therefore,

$n= \dfrac{V_2*n_1}{V_1}$

$n= \dfrac{18.3*6.51}{6.13}$

n = 19.43

$n=n_1+n_2$

19.43 = 6.51 + n₂

n₂ = 19.43 - 6.51

n₂ = 12.92 moles

Thus; the final mole of the flexible container = 12.92 moles

If you wanted to make 0.800 Liters of a 0.531 M solution of Nickel(II) chloride, NiCl2, how many grams of NiCIZ

kotegsom [21]

Answer:

54.8g

Explanation:

1. Calculate the number of moles of NiCl₂

a) Identify the known variables

V =0.800 liters
M = 0.531M
n = ?

b) Formula

$M=\dfrac{n}{V}$

c) Clear n

$n=M\times V$

g) Substitute and compute

$n=0.531M/times 0.800liters=0.4248mol$

2. Convert moles to grams

a) molar mass of NiCl₂

129g/mol (shown in the problem)

b) Unit canceling method

Use the factors in order to cancel the units to obtain grams

$0.4248mol\times 129\dfrac{g}{mol}=54.7992g$

Note that the mol unit appears on the numerator and denominator, so it cancels leaving just g (grams).

c) Round to 3 signficant figures

$54.8g$
