mass in grams of 3.32 mol k

Answers

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

What is the ground-state electron configuration of chlorine and the number of valence electrons in it?

Answers

Explanation:

Chlorine is an element in group 7 on the periodic table.

  It is the second element in this group of halogens

 The element has a total of 17 electrons:

Ground state configuration  = 1s² 2s² 2p⁶ 3s² 3p⁵

Valence electrons are the outermost shell electrons;

  From the configuration: 3s² 3p⁵ is the valence shell

           Number of electrons  = 2 + 5  = 7

What is the difference between heat of formation and heat of reaction? Give examples and units

Answers

Answer:

The main difference between the heat of formation and heat of reaction is that heat of formation is the amount of energy either absorbed or released during the formation of a compound whereas heat of reaction is the amount of energy either absorbed or released during any chemical reaction.

What general trend do you observe in the periodic table of the Atomic Radius?

Explanation:

Explain why, in a balanced chemical equation C + O2 CO2, we know that 1 gram of C will not react exactly with 1 gram of O2.

Answers

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.

If a 200 kg person stands next to a 100 kg person. Which person would have a larger gravitational attraction?

Answers

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.

fill in the blank please

Answers

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.

A pH of 1 there are a lot of ______ in a solution. 2.A pH of 14 there are a lot of ______ in a solution.

Answers

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.

The pH scale ranges from 1 to 14 As the values tends towards 1, the acidity increases due to concentration of hydroxonium ions in the solution. As the pH tends towards 14, the basicity increases due to the concentration of hydrogen ions in the solution.

A landslide is also called a land slip. It refers to several forms of mass wasting and may include a wide range of ground movements. They occur in a variety of environments characterize by gentle and steep slope gradients.

The mudflow is a mixture of rocks and soil along with water. While a creep is a slow downloads movement of rocks and soil.

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

Can one mole of peas fit inside your house? List the materials and steps of an experiment that answers the
question without actually filling up your house with peas!

Answers

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.

calculate the percentage of iron in iron (III) sulphate

Answers

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.
