Answer:

coal is made from compressed plant matter and how exactly did plants grow on the surface of an ocean. (as there is no land mass beneath the arctic.)

Explanation:

it would be like finding a fly in an ice cube to simplify it.

They were surprised to find coal in arctic because ordinarily coal was supposed to be found in warm or hot environments and not cold region like the arctic.

The arctic is located at the far northern part of the world which is characterized by its extreme cold weather.

A limited vegetation of plants such as grasses, mosses and lichens are found in this region irrespective of the extreme cold weather through out the year.

Coal is a type of fuel gotten from fossils and deposits of plant vegetation.

Scientist has discovered that continents do move over time through a process called continental drift. This is the reason why limited vegetaion is found in the arctic leading to the formation of coal.

Answer:

There are 0.12269 Liters of Iron

Explanation:

First, by means of the molecular weight equation, the grams of iron corresponding to 17.3 moles can be calculated:

[tex]MW=\frac{mass(grams)}{moles}[/tex]

[tex]mass=MW*moles=55.845\frac{g}{mol} *17.3mol=966.119 g[/tex]

Then using the density equation the iron milliters are calculated:

[tex]d=\frac{mass(g)}{volume(mL)}[/tex]

[tex]volume=\frac{mass}{density}=\frac{966.119g}{7.874\frac{g}{mL} } =122.69 mL[/tex]

Milliliters to liters are converted:

122.69 mL = 0.12269 L of Iron.

Answer:

[tex]V_{Fe}=0.125L[/tex]

Explanation:

Hello,

In this case, given the moles of iron, we need to use it atomic mass (55.845  g/mol) and density (7.874 g/cm³) in order to firstly convert from moles to grams and secondly from grams to cubic centimetres:

[tex]V_{Fe}=17.6molFe\times \frac{55.845gFe}{1molFe}*\frac{1cm^3}{7.874gFe}=124.8cm^3[/tex]

Finally, we obtain the volume in litres by:

[tex]V_{Fe}=124.8cm^3*\frac{1L}{1000cm^3} \\\\V_{Fe}=0.125L[/tex]

Best regards.

Answer:

The equilibrium concentration of gas A is 1.43 M

Explanation:

Here we have the reaction expressed as follows;

A + B → C + D and

The formula for equilibrium constant is therefore presented as follows;

[tex]K = \frac{[C]\times [D]}{[A]\times [B]}[/tex]

Where:

[C] = [D] = 2.3 M

[A] = [B]

K = 2.6

Hence, we have;

[tex]2.6 = \frac{2.3\times 2.3}{[A]\times [A]} = \frac{5.29}{[A]^2}[/tex]

[tex][A]^2= \frac{5.29}{2.6} = 2.03[/tex]

[A] = 1.43 M

The equilibrium concentration of gas A = 1.43 M.

Answer:

The equilibrium concentration of gas A = 1.43 M

Explanation:

First set up the equilibrium expression:

[tex]K = \frac{[C]\times [D]}{[A]\times [B]}[/tex]

The problem states that each product has a concentration of 2.3M at equilibrium, and that k=2.6

We also know that [A] and [B] are the same.

Since we are solving for [A] I'm going to change [A][B] to A²

[tex]2.6 =\frac{2.3^2}{A^2}[/tex]

Now we just need to solve for A²

A² = 5.29 / 2.6

A² = 2.0346

A = √2.0346

A = 1.43

Therefore, the equilibrium concentration of gas A = 1.43 M.

Answer:

6.0 x 105

Explanation:

Answer:6.0 x l05

Explanation:

Answer:

0.479 M or mol/L

Explanation:

So Molarity is moles/litres of solution...often written as M=mol/L

So here we are given grams of BaCl2 which we have to convert to moles. To convert to moles of BaCl2 we have to divide 63.2 g BaCl2 by molar mass of BaCl2 which is 208.23 g/mol so you get 63.2/208.23 = 0.3035 moles of BaCl2

Second step is converting the 634mL to litres by simply dividing by 1000 because we know 1 litre has 1000ml so 634/1000 = 0.634L

Now we just plug these guys in our molarity formula M=mol/L

M= 0.3035/0.634 = 0.479 M or mol/L

Start by calculating the percent composition of chlorine,

To do that, use the molar mass of calcium chloride, the molar mass of elemental chlorine, and the fact that

This means that for every

63.89 g

of chlorine.

As you know, the mass of an ion is approximately equal to the mass of the neutral atom, so you can say that for every

100 g

of calcium chloride, you get

63.89 g

of chloride anions,

Cl

This implies that your sample contains

Now, in order to find the mass by volume percent concentration of chloride anions in the resulting solution, you must determine the mass of chloride anions present in

100 mL

of this solution.

Since you know that

500 mL

0.3469 g

Answer:

D. They are usually liquids or gases at room temperature.

Explanation:

Covalent compounds have covalent bonds, meaning that they share electrons between elements and have relatively higher melting melting and boiling points due to the strength of their bonds. However covalent bonds are weaker than ionic bonds which is why B is correct. D is the only incorrect one because it is incorrect and contradicts point C. If a substance has a high melting/boiling point than it is much more likely to be solid at room temperature because of the high temperature it needs to pass in order to be a liquid or gas.

 24He

Explanation:

When a nuclide is bombarded with alpha particles, we notice an increase in its mass and charge since an alpha particle has a mass of four and a charge of +2. recall that nuclear equations must be balanced. That is, the masses and charges on the left hand six and the right hand side of the nuclear reaction equation must be exactly the same.

Looking at the nuclear reaction at hand, the total mass on the left hand side has to be 246 while the total charge on the left hand side of the equation will be 98. Coming over to the right hand side, the total masses are also found to be the same as a neutron with no charge and a mass of 1 is produced. Hence the nuclear reaction equation is balanced when an alpha particle (helium nucleus) is substituted for X in the equation.

Explanation:

u got ig?

A curved piece of glass or other transparent material that is used to refract light is called a lens. The correct option is B).

A curved piece of transparent material, such as glass, that bends light is called a lens. A lens's shape and the object's position both affect the kind of image it produces.

The center of a concave lens is thinner than the edges. Bent glass is defined as glass that has been curved or bent into a convex or concave shape. The desired shape is created by gently heating the glass until it becomes pliable, then molding it into that shape.

Light is refracted through lenses. When a light beam enters a lens, it is refracted; then, when it leaves the lens, it is refracted once more.

Therefore, the correct option is the B) lens.
