A meteorologist predicts fog in the morning over lakes and river bottoms because of the atmospheric conditions and their interactions with the hydrosphere. The hydrosphere is the region on the Earth's surface where the total water on the planet is found. The hydrosphere can be in the form of liquid, vapor, or ice.

In this equation, what should be the coefficients of the reactants and products? I2 + O2 → I4O9

Answers

I am thinking that you are asking for the balanced equation for this chemical reaction. In order to balance this, you have to count each element where the elements in the reactants side and the product side should have equal number of molecules. The balanced reaction is as follows:

2I2 + 9/2O2 → I4O9

Which of the following metal atoms would have the highest conductivity?

Answers

Conductivity is a way that an atom reacts. Therefore, when we say "highest" we mean the most reactive. Elements or atoms that are highly reactive are those that want to be stable. Therefore, the atoms that have 7 valence electrons would be highly reactive because they need 1 more electron to fill their outer energy shell to become stable.

Answer:The atom with the largest radius and the most valence electrons.

Explanation:it just makes sense and it’s also right.

Potassium hydroxide is classified as an Arrhenius base because KOH contains(1) OH- ions (2) O2- ions (3) K+ ions (4) H+ ions

Answers

Answer : The correct option is, (1) $OH^-$ ions.

Explanation :

According to the Arrhenius concept, an acid is a type of substance which ionizes in water to gives $H^+$ ions (hydronium ions or hydrogen ions) and a base is a type of substance which ionizes in water to gives $OH^-$ ions (hydroxide ions).

As we know that KOH is a base which ionizes in water to gives $OH^-$ ions (hydroxide ions) and $K^+$ ions.

Hence, potassium hydroxide is classified as an Arrhenius base because KOH contains $OH^-$ ions.

The answer is (1)OH- ions. The base has more OH- ions while the acid has more H+ ions. And if you dissolve them into water, the pH of the solution is also different. Base has pH>7 and acid has pH<7 at room temperature.

Will a precipitate form when NaCl(aq) and AgNO3 (aq) are mixed together?

Answers

yes,because they are both soluble salts so they form an insoluble salt which will be the precipitate formed

What is an ionic bond?

Answers

In ionic bond there is the formation of ions due to transfer of electrons from one atom to the other. Normally, at this link, there is an element that tends to yield electrons (metal-cation), and one that tends to receive electrons (not metal-anion).
Note: the Ionic bond is the only in the transfer of electrons.

Ionic bonds are when atoms lose or gain electrons so that both elements now have a full outer shell. Ionic bonds form between metals and nonmetals.
