Predict the ions that form when magnesium(group IIA) and nitrogen (group VA) react:.
Answers
Answer: Mg²⁺ & N³⁻
Explanation:
Since Magnesium is in group 2, then it favors losing two electrons forming a cation with a charge of +2 ( Mg²⁺).
Since Nitrogen is in group VA, it favors gaining three electrons forming the anion with charge -3 (N³⁻).

X has 9 Electrons, 9 Protons and 10 Neutrons
X is Fluorine
Explanation:
19 in X is Nucleon number
So, if you minus 19 by 9 down there (which is proton number) you'll get 10 (Neutron number).
Now, Proton = Electron. That's why Electron is 9 too. I figured that X is Fluorine bcuz it has 9 Electrons. If you venture around in the periodic table, fluorine is the ninth element innit.

in an oxidation-reduction reaction, how is the reducing agent changed?
Answers
Explanation: The additional terminology comes from the definition that, within redox processes, a reductant transfers electrons to an oxidant; hence, the reductant (reducing agent) loses electrons, so is oxidized, while the oxidant (oxidizing agent) gains electrons, so is reduced.
In an oxidation-reduction reaction, the reducing agent loses electrons and loses potential energy, Therefore, option (C) is correct.
What is a reducing agent?A substance that loses its electrons in a redox reaction to other substances and gets oxidized is called a reducing agent. A reducing agent is one of the reactants which reduces the other reactant by donating the electrons to the reactant of an oxidation-reduction reaction.
If the reducing agent can't pass electrons to another reactant in a reaction, then the reduction process does not occur and the reaction cannot proceed.
In redox reactions, when an electron loses potential energy as a result of the transfer and energy is released. Electrons with more potential energy are associated with less electronegative atoms and less potential energy is associated with a more electronegative atom (such as O).
Therefore, the reducing agent loses electrons and loses potential energy in a redox reaction.

how to calculate atomic mass of sodium ?(in process)
Answers
Answer:
Atomic mass of Sodium is 22.9897 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is the atomic mass unit (amu). One atomic mass unit is equal to 1.66 x 10 -24 grams.

what is the molarity of an hcl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400 m naoh? group of answer choices 0.200 m 0.280 m 0.320 m 0.500 m
Answers
The molarity of an HCl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400M NaOH is 0.320 M.
HOW TO CALCULATE MOLARITY:
The Molarity of an acid when involved in a titration procedure can be calculated by using the formula below:M1V1 = M2V2
Where;
M1 = molarity of acid (M)M2 = molarity of base (M)V1 = volume of acid (mL)V2 = volume of base (mL)According to this question,
M1 = ?M2 = 0.400MV1 = 50 mLV2 = 40 mLM1 × 50 = 0.400 × 40
50M1 = 16
M1 = 16 ÷ 50
M1 = 0.32M
Therefore, the molarity of an HCl solution if 50.0 ml is neutralized in a titration by 40.0 ml of 0.400M NaOH is 0.32 M.Learn more at: https://brainly.com/question/8732513?referrer=searchResults

A non-covalent interactions between molecules are van der Waal's forces and hydrogen bonds.
What are non-covalent interactions?
Non-covalent interaction is an interaction which does not involve sharing of electrons and in this aspect it differs from covalent bond.It rather involves dispersed variations of electromagnetic interactions which are present between the molecules or within the molecule.
The energy released during the formation of these interactions is of the order of 1-5 kcal .They are classified as electrostatic, pi effects , van der waals forces and hydrophobic effects.
They are important in maintaining the three dimensional structure of large molecules such as proteins ,nucleic acids ,etc.They are also involved in biological processes . They heavily influence drug design process and design of materials.

Answers
Answer:
A mixture of solid particles and gases in the air.
Explanation:
Air pollution is a mixture of solid particles and gases in the air. car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.
Air pollution can be defined as the presence of toxic chemicals or compounds (including those of biological origin) in the air, at levels that pose a health risk. In an even broader sense, air pollution means the presence of chemicals or compounds in the air which are usually not present and which lower the quality of the air or cause detrimental changes to the quality of life (such as the damaging of the ozone layer or causing global warming).

Methane (CH4) is a gas that is found in small quantities in Earth’s atmosphere. Which type of bonds does methane have, and why does one carbon atom bond with four hydrogen atoms? In three to five sentences, explain your answer in terms of valence electrons and electronegativity.
Answers
In methane, the covalent bond is present between one carbon and four hydrogen atoms.
What is methane?Methane is the simplest form of saturated hydrocarbons. Methane is an odorless gas as well as a colorless gas. It has one carbon and four hydrogen atoms which is why methane is also called a tetrahedral molecule.
CH₄ is the chemical formula of methane and is a non-toxic but flammable gas. From the tetrahedral structure of methane, we can see that a carbon atom is bonded to four hydrogen atoms.
One molecule of methane contains four covalent bonds. Each covalent bond is formed between the carbon and one hydrogen atom. The formation of a covalent bond between carbon and hydrogen is due to the small electronegativity difference between carbon and hydrogen.
In this way, carbon completes its octet and hydrogen completes its duplet. Therefore, the covalent bond is formed between one carbon atom bond with four hydrogen atoms in methane.

Explain how the fire spreading from tree to tree provides a model for conduction.
The great fire of 1910 burned through parts of north Idaho, western Montana, eastern Washington,and southeastern British Columbia. Many small fires and several large fires that were started by an electric storm coalesced into one”big blowup” of unprecedented size that lasted two days. Hurricane-force winds spread the firestorm; trees became blowtorches, sucking fire from the ground and hurling it in several directions, spreading the fire on contact. Witnesses described fireballs being flung like cannons. Trees exploded like fireworks. The fire killed 87 people, destroyed towns in its path, and burned more than three million acres of forest

in the reaction of aluminum metal and oxygen gas to make aluminum oxide, how many moles of aluminum will react with 0.80 grams o2?
Answers
Answer:
When 6.38 moles of O2 and 9.15 moles of Al react, the ratio of aluminum to oxygen is 9.15/6.38 = 1.434. This shows that all of the oxygen is consumed before the aluminum and when the reaction ends the reactant aluminum is left. The number of moles of Al2O3 formed is approximately 4.25 moles.
