PLZ help can you find a picture of the IODINE PLANITERY model please help

Answer:

See the answer below

Explanation:

From the equation, 1 mole of C requires 1 mole of O2 for a balanced reaction.

1 g of C will not exactly react with 1 g of O2 because the 1 g of each of the reactants contain different amounts of the substance.

The amount (in moles) of a substance is the mass of that substance divided by the molar mass.

Hence, 1 g of C will contain 1/12 moles of the substance while 1 g of O2 will contain 1/32 moles of the substance.

Answer:

Nonmetal

Explanation:

A substance in the chart is a nonmetal because nonmetals are not water soluble, they are poor conductors of heat and electricity and they do not have high melting points like metals.

Answer:could it be kilo

Explanation:it looks like it has the least letters

Answer:

200 kg

Explanation:

the 200 kg person is heavier due to gravity's force the 100 kg person has less force than the other person

Answer:

massive one that is 200kg

Explanation:

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Answer:

c

Explanation:

I am not sure why your teacher isn't asking for the layers, but here is the list of layers;

A -(topsoil) Mostly minerals from parent material with organic matter incorporated. A good material for plants and other organisms to live.

E - (eluviated) - Leached of clay, minerals, and organic matter, leaving a concentration of sand and silt particles of quartz or other resistant materials – missing in some soils but often found in older soils and forest soils.

B - (subsoil) Rich in minerals that leached (moved down) from the A or E horizons and accumulated here.

C - (parent material) The deposit at Earth’s surface from which the soil developed.

R - (bedrock) A mass of rock such as granite, basalt, quartzite, limestone or sandstone that forms the parent material for some soils – if the bedrock is close enough to the surface to weather. This is not soil and is located under the C horizon.

Answer:

First one: Yes, It can be negative.

Explanation:

First one: The reason you can have negative acceleration is that acceleration can slow down, or decelerate, causing the negative acceleration.

Answer:

Hydrogen or hydroxonium ions in the solution

Hydroxyl ions in the solution

Explanation:

A pH of 1 shows there is a lot of hydroxonium ions in the solution and a pH of 14 shows there is a lot of hydroxyl ions in the solution.

Explanation:

that my answer I got i think its correct

Answer:

Explanation:

Those are the answers in order, BUT the Goldstein and Rutherford ones are confusing me because Rutherford discovered protons and the nuclear atom. Through my research I also noticed that Goldstein contributed to the discovery of the protons made Rutherford, so I listed him as the one who discovered the proton.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{3.55 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.05897...[/tex]

We have the final answer as

Hope this helps you

Answer:

The halogenation of propane discloses an interesting feature of these reactions. All the hydrogens in a complex alkane do not exhibit equal reactivity. For example, propane has eight hydrogens, six of them being structurally equivalent primary, and the other two being secondary

Explanation:

The solids can be classified on the basis of bond they are joined with. There are four types of solids on the basis of bond. There are four type of  crystalline solids: namely,  molecular solids, network solids, ionic solids, and metallic solids. The molecular and the structure of the solid determines its properties likes conductivity, solibility, heat conductivity, and density. Solids are incompressible and rigid as there molecules are fixed in place.

Answer:

Atoms, Molecules, Extended Structures, and Substances

High arky of solids

Answer:

nitrogen dioxide

Explanation:

this was on my chemistry test

1. 92 g

2. 5.4 g

3. 0.217 moles

The mole is the number of particles(molecules, atoms, ions) contained in a substance  

1 mol = 6.02.10²³ particles

Can be formulated

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

Moles can also be determined from the amount of substance mass and its molar mass

[tex]\tt n=\dfrac{m}{MW}[/tex]

1. the mass of 4 moles of Na(MW= 23 g/mol)

[tex]\tt mass=mol\times MW\\\\mass=4\times 23\\\\mass=92~g[/tex]

2.  the mass of 0.3 moles of water(MW=18 g/mol)

[tex]\tt mass=mol\times MW\\\\mass=0.3\times 18\\\\mass=5.4~g[/tex]

3. the number of moles found in 10g of ethanol C2H5OH(MW=46 g/mol) :

[tex]\tt mol=\dfrac{10}{46}\\\\mol=0.217[/tex]

Answer:

Electrolysis of water

Explanation:

The electrolysis of water is a decomposition reaction in which electricity is used to break down a compound into simpler molecules.

Decomposition of water is carried out in the Hofman Voltameter.

This process is achieved by passing current through an acidified water.

The expression is given as:

               2H₂O →  2H₂   +  O₂

Answer:

Fossil fuels are non-renewable which means that they wont last forever and they contribute largely to unnatural climate change.

Explanation:

Answer:

28.01 percent

Explanation:

Iron (III) sulphate, [tex]Fe_2(SO_4)_3[/tex], has 2 atoms of Fe.

One atom of Fe has a molar weight of 56. Hence, 2 atoms of Fe would have a total molar weight of 56 x 2 = 112 g/mol

Molar weight of  [tex]Fe_2(SO_4)_3[/tex] = 399.88 g/mol

Percentage Fe in [tex]Fe_2(SO_4)_3[/tex] = 112/399.88 x 100%

                       = 28.01%

The percentage of iron is iron (III) sulphate is, therefore, 28.01 percent.

Answer:

No.

Explanation:

No, one mole of peas do not fit inside a house because one mole is equals to 6.022 × 10²³ units which is a very large value. mole only use for atoms, ions and molecules etc due to very small size but mole is not used for big sized materials such as peas and other vegetables etc. So that's why we can conclude that one mole of peas did not fit inside a house.

Answer:

590 g CaCl₂

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

5.3 mol CaCl₂

Step 2: Identify Conversions

Molar Mass of Ca - 40.08 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of CaCl₂ - 40.08 + 2(35.45) = 110.98 g/mol

Step 3: Convert

[tex]5.3 \ mol \ CaCl_2(\frac{110.98 \ g \ CaCl_2}{1 \ mol \ CaCl_2} )[/tex] = 588.194 g CaCl₂

Step 4: Check

We are given 2 sig figs. Follow sig fig rules and round.

588.194 g CaCl₂ ≈ 590 g CaCl₂

Answer:

129.8 grams

Explanation:

Im a bit confused of what your are asking but if your are asking the mass in grams of K (Potassium) it is very easy dont worry

You multiply mols x Molecular weight.

So

3.32x 39.1= 129.8 grams
