Answer:

B

Explanation:

If AH and AS are both negative  will a low temperature make a reaction spontaneous.

A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. A roaring bonfire (see figure below) is an example of a spontaneous reaction.

A fire is exothermic, which means a decrease in the energy of the system as energy is released to the surroundings as heat.

The products of a fire are composed mostly of gases such as carbon dioxide and water vapor, so the entropy of the system increases during most combustion reactions.

Therefore,  If AH and AS are both negative  will a low temperature make a reaction spontaneous.

Answer:

Explanation:

CH4 + 2O2 ==> CO2 + 2H2O

mols CH4 = grams/molar mass

Using the coefficients in the balanced equation, convert mols CH4 to mols CO2.

Now convert mols CO2 to grams. g = mols x molar mass.

Answer: Is B: the supply will eventually be exhausted.

Explanation:

there is only so much coal in the world as in many other elements. That is why we are looking for more appropriate and resourceful way of supplying energy and it is a lot safer for the workers involved

As coal is a nonrenewable source of energy so its supply will eventually be exhausted. Therefore, option (B) is correct.

Non-renewable energy can be described as energy that comes from fossil fuels such as coal, natural gas, crude oil, and uranium. Non-renewable energy requires human intervention to create it suitable for consumption. Fossil fuels are generally made up of Carbon. Fossil fuels were produced over 300 million years ago.

Non-renewable energy is generally fossil fuels such as coal, oil, natural gas, etc. Fossil Fuels are produced from the remains of animals and plants and can be is divided into three categories.

To produce natural gas from fossil fuels, the decomposition process is longer and conducted with high amounts of pressure and heat. Coal takes millions of years under the crust of the earth to produce through the decomposition of trees, plants, and ferns.

The atomic mass of K is 39

from Avogadro's law

39g of K contains 6.02x10^23 atoms

therefore if

39=6.02x19^23

X=5.11×10^22

making X the subject of the formula

X= (5.11×10^22×39)÷6.02×10^23

X= 33g

The statement, that describes grams of potassium (K) contain 5.11 × [tex]10^{22}[/tex] atoms is "33.1 g."

An atom is a fundamental particle of matter that contains at least one proton.

1 mole will be of 6.022 × [tex]10^{23}[/tex] atoms

Then,

[tex]= 5.11*10^{22} \;atoms\;.\;\frac{1\;mol}{6.022*10^{23} \;atoms} \;.\;39.098\;g/mol\\\\= 33.171\;g[/tex]

≈ 33.1 g

As a result, 33.1 g of K contains 5.11 × [tex]10^{22}[/tex] atoms.

Hence, the correct option is 33.1 g.

Answer:

I would say baking powder maybe or you should try tap water

Answer:

1st one - tap water (ill go over them one by one to help you understand why)

Its honestly rather vinegar or tap water but if I would go with tap water however I could be wrong. I don't take your class lol

Step by step:

First, tap water includes a lot of ions and contaminants. As a result, tap water only contains ions capable of conducting electricity. As a result, tap water is an excellent electrical conductor.

2nd) Ammonia and baking soda are both weak bases. When weak electrolytes dissolve in water, the resulting solution has a low conductivity.

Third, because it releases H+ and CH3COO- ions, the mobility of these ions in the solution assists in electrical conduction. As a result, vinegar is a good electrical conductor.

4th) When dissolved in water, soda compounds (chemicals mostly containing sodium) include ions, and ions assist conduct electricity. As a result, it does not conduct because it lacks ions or charged particles.

Answer:

BY The Editors of Encyclopaedia Britannica | View Edit History

ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms. Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.

Explanation:

Answer:

Explanation:

Molar mass of Lithium is 6.9410 g/mol.

This means 1 mol of Li atoms weigh 6.9410 g

In 1 mol 6.022 x 10 ^ 23 atoms should be present

So, in 6.9410g , there should be 6.022 x 10 ^ 23 atoms.

So weight of 1 atom = a =  6.9410  g / (6.022 x 10^ 23)

To find weight of 3.25 x 10 ^ 24 atoms we have to multiply a by 3.25 x 10^ 24

So you will get the answer as

[6.9410  g / (6.022 x 10^ 23)]   x 3.25 x 10^ 24

= 37.46 g

The order of increasing ionic property is;

WO3 < ZrS2 < MnS2< ZnS < MnS

Ionic compounds are compounds that contain an ion pair. Typically, ionic compounds are formed between metals and nonmetals.

The degree of ionic character depends on the type of metal involved and the magnitude of charge it carries.

Typically, first row transition metals form ionic compounds. The degree of ionic character depends on the row in which the metal is found and the magnitude of charge it carries.

Hence, the order of ionic character of the compounds from most ionic to least Ionic is; WO3 < ZrS2 < MnS2< ZnS < MnS.
