C. (-2,-2) is the answer.

Explanation:

When we reflect a point (x, y) across the y-axis, after the reflection, the y-coordinate tends to be the same, however the x-coordinate is changed into its opposite sign.

Here U(2,-2) is reflected across the y-axis then,

the y-coordinate -2 remains the same and the x-coordinate is transformed into its opposite that is the sign of the x-coordinate will be changed as -2.

So the new coordinates of U after reflection will be (-2,-2).

Consider a iron-silver voltaic cell that is constructed such that one half-cell consists of the iron, Fe, electrode immersed in

MissTica

Answer:

See explanation

Explanation:

In the voltaic cell, energy is produced by spontaneous chemical reaction. One half cell functions as the anode (in this case it is the Fe/Fe^2+ half cell) while the other half cell functions as the cathode (in this case it is the the Ag/Ag^+ half cell).

At the anode;

Fe(s) -----> Fe^2+(aq) + 2e

At the anode;

2Ag^+(aq) + 2e ------> 2 Ag(s)

Overall cell equation;

Fe(s) + 2Ag^+(aq) ------> Fe^2+(aq) + 2 Ag(s)

Aqueous solutions of silver nitrate (agno3) and iron(iii) chloride (fecl3) are mixed together. which ion combines with the chlor

Anna [14]

The answer is that "Ag+ ion combines with the chloride ion to form a precipitate".

Silver chloride is formed in the form of precipitates, Ag⁺ is a cation and Cl⁻ is an anion so both ions attract each other and combines to form AgCl.

The equation for the ionic reaction that occurs is;

Ag⁺(aq)+Cl⁻(aq)→AgCl(s)

If the prefix hydro were used to name a ternary acid, what problem would this create when naming chloric acid

Lady_Fox [76]

Hydrochloric acid is a different kind of acid than chloric acid.

Ternary Acids (Oxy-acids) Ternary acids are also referred to as “Oxy-acids. Include hydrogen and oxygen and yet another (normally) nonmetallic detail. Those acids comprise each hydrogen and oxygen but their names make no reference to either hydrogen or oxygen.

A ternary acid is an acid that has the elements hydrogen and oxygen together with every other element, frequently a nonmetal. Or, they comprise hydrogen in addition to a polyatomic ion. An -ate complicated ion is named an -ic acid. as an example, HClO3(aq) consists of the chlorate ion and is known as chloric acid.

A binary acid is an acidic compound that always has hydrogen boned to every other chemical element, most of the time a nonmetal. Ternary acids are acidic compounds that comprise hydrogen and oxygen blended with some other detail. Binary acid has one style of a chemical element (hydrogen bonded to a nonmetal) .

Which compound has both ionic and covenant bonds

Mashutka [201]

Answer:

Calcium carbonate is another example of a compound with both ionic and covalent bonds.

Explanation:

In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.
