Which of the following is the best way to model the process of weathering?

Using a fan on a pile of sand causing the sand to move into a pile in a new location.

Using a ramp to dump sand at the bottom causing the sand to pile up.

Using a watering can sprinkle water onto sand causing the sand to move to a new location.

Answer 2

The best model of weathering is using a fan on a pile of sand causing the sand to move into a pile in a new location.

Weathering refers to the gradual breakdown of a rock due to the agents of denudation. The agents of denudation could be physical, chemical or biological.

The breakdown of rocks leads to the formation of soil. The closest model to the weathering of rock is using a fan on a pile of sand causing the sand to move into a pile in a new location.

The pile represents the rock which is being broken down as the fan blows the pile and it settles on a new location.

Magnesium (24.30 g) reacts with hydrogen chloride (X g) to produce hydrogen gas (2.04 g) and magnesium chloride (96.90 g). How much hydrogen chloride was used in the reaction?

Answers

Answer:

[tex]74.64\ \text{g}[/tex]

Explanation:

Reactants

Magnesium = 24.3 g

Hydrogen chloride= x g

Products

Hydrogen gas = 2.04 g

Magnesium chloride = 96.9 g

As the mass of the reactions is conserved we have

Mass of reactants = Mass of products

[tex]24.3+x=2.04+96.9\\\Rightarrow x=2.04+96.9-24.3\\\Rightarrow x=74.64\ \text{g}[/tex]

Mass of hydrogen chloride is [tex]74.64\ \text{g}[/tex].

What is the mass of 0.0467 mol of the element sodium (Na)

Answers

Answer:

Explanation:

All periodic tables list different amounts of elemental masses. I'm going to round Sodium to 23

1 mol of sodium = 23

0.0467 mol sodium = x

Cross multiply

1*x = 0.0467 * 23

x = 1.0741 grams

You can also do it this way

The equation to find
moles(n) = m(g)/M(g.mol^-1)

Therefore if you rearrange the equation to find the mass(g) you can solve.

m = nM
m = (0.0467mol) * (22.99g.mol^-1)
m = 1.0736g

SOLVED!!

n = moles
m = grams
Molar mass = g.mol^-1 = grams per moles

A) A test/independent variable is the variable that is being tested in the experiment or research and it is not affected by other variables in the experiment.

Now, in this experiment, what is being tested is are the bat wings.. Thus;

Test(independent) variable is bat wings.

B) Result (dependent) Variable is a variable that depends on the independent variable being tested. From the question, the result is the Polyjuice Potion.

Thus, Result (dependent) Variable is the Polyjuice Potion.

A bottle has a capacity of 1.2 liters. If the density of ether is 0.74 g/mL, what mass of ether can the bottle hold?

Answers

Answer:

Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. We calculate as follows:

Volume = 60.0 g ( 1 mL / 0.70 g ) = 85.71 mL

Therefore, the correct answer is option B.

Explanation:

888 grams is a mass of ether that the bottle can hold.

Explanation:

The density of the substance is defined as a mass of substance present in the unit volume of the substance.

[tex]Density=\frac{Mass}{Volume}[/tex]

Given:

A bottle with a capacity of 1.2 Liters.

The density of ether = 0.74 g/mL

To find:

The mass of ether hold by a given bottle.

Solution:

The volume of bottle = V = 1.2 L

[tex]1 L = 1000 mL\\V = 1.2 L=1.2\times 1000 mL= 1200 mL[/tex]

The density of the ether = d = 0.74 g/mL

The mass of ether that bottle can hold = m

Volume of ether required = Volume of bottle = V = 1200 mL

Using the formula of density:

[tex]d=\frac{m}{V}\\0.74 g/mL=\frac{m}{1200 mL}\\m=0.74 g/mL\times 1200 mL= 888 g[/tex]

888 grams is a mass of ether that the bottle can hold.
