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.
If you have 4.01 g of H2, how many grams of NH3 can be produced?
Answers
Answer:
136.5886g of NH3
Explanation:
N2 + 3H2 = 2NH3
The mass of the N2 = 4.01
3H2 has a 2/1 ratio
This means the mass of 3H2 is twice as much as N2.
NH3= 2*N2 = 2*4.01 = 8.02 of NH3
Then, by multiplying the mass by MX (17.031)
8.02*17.031=136.5886g can be produced. Round it if needed.

What determines an object’s ability to float?
Answers
For example, a suitcase jam-packed with clothes and souvenirs has a high density, while the same suitcase containing two pairs of underwear has low density. Size-wise, both suitcases look the same, but their density depends on the relationship between their mass and volume.
Mass is the amount of matter in an object.
Volume is the amount of space that an object takes up in three dimensions.
Density is calculated using the following equation: Density = mass/volume or D = m/v.
If something is heavy for its size, it has a high density. If an object is light for its size it has a low density.
The relative densities of an object and the liquid it is placed in determine whether that object will sink or float.

Under what conditions will a low temperature make a reaction spontaneous?
O A. If AH and AS are both positive
O B. If AH and AS are both negative
O c. If a catalyst is used in the reaction
O D. If the reaction is endothermic
Answers
Answer:
B
Explanation:
If AH and AS are both negative will a low temperature make a reaction spontaneous.
What is Spontaneous reaction?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.

Why is mining for coal a long-term concern?
A. It is being replenished faster than it can be mined.
B. The supply will eventually be exhausted.
C. New methods of mining need to be developed.
D. The demand for coal is diminishing.
Answers
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.
What are nonrenewable sources of energy?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 number of moles present in 29.5 grams of argon is 0.74 mole.
The atomic mass of argon is given as;
Ar = 39.95 g/mole
The number of moles present in 29.5 grams of argon is calculated as follows;
39.95 g ------------------------------- 1 mole
29.5 g ------------------------------ ?
[tex]= \frac{29.5}{39.95} \\\\= 0.74 \ mole[/tex]

Determine the amount of grams present in
3.25x1024 atoms of Lithium.
Answers
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
