Answer:

FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl

Explanation:

You are given a skeleton equation, or unbalanced equation.

FeCl₃ + NaOH → Fe(OH)₃ + NaCl

Count the number of atoms on each side. If there is 1 atom, the subscript is not written. If the subscript to the right of a bracket, it belongs to each element in the bracket.

Reactants → Products

Fe 1 Fe 1

Cl 3 Cl 1 Not balanced

Na 1 Na 1

O 1 O 3 Not balanced

H 1 H 3 Not balanced

The number of each element must be the same in the reactants and products. We can see that Cl (chlorine), O (oxygen) and H (hydrogen) have different numbers.

Write in coefficients in front of formulas (separated by + sign). Coefficients multiply each subscript (or "1" if not written) in the formula. Recount the atoms until you have equal reactant and product atom numbers.

I see that I need more chlorine in my products. Multiply the formula that has "Cl" by 3.

FeCl₃ + NaOH → Fe(OH)₃ + 3NaCl

Reactants → Products

Fe 1 Fe 1

Cl 3 Cl 3 Cl is balanced now.

Na 1 Na 3 Not balanced

O 1 O 3 Not balanced

H 1 H 3 Not balanced

Fix the "Na" now. Multiply the formula with "Na" on the left by 3.

FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl

Reactants → Products

Fe 1 Fe 1

Cl 3 Cl 3

Na 3 Na 3

O 3 O 3

H 3 H 3

Each side has the same number of each element. Therefore, this is balanced now.

Balanced formula:

FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl

Explain what "LEO the lion goes GER" means based upon what you have learned

olchik [2.2K]

"LEO the lion goes GER" means based upon the oxidation and reduction reactions.

<h3>What is oxidation and reduction reaction?</h3>

Oxidation reactions are those reactions in which lossing of electrons are taking place from the substrate molecule and in reduction process gaining of electrons is done by substrate molecules.

The phrase "LEO the lion goes GER" is used in the context of oxidation and reduction reactions. Meaning of the terms:
LEO → Lose electrons = oxidation

GER → Gain electrons = reduction

Hence the given line is based on oxidation and reduction.

-Packaging

-Positioning

-People

Promotion

Promotion essentially includes all the methods,ways and means you inform your customers about your product or services and how one can market the products and make sales from them.Apple's "creative pros" and "evangelists" basically promote Apple products by their activities since they make the customers know more about what Apple products can do thereby getting support for the Apple product which serves as a form of publicity for the products and as the publicity increases it would increase the sales of Apple products.Just as advertising serves to increase sales.

the mass of a liquid is 11.50 g and its volume is 9.03 mL. How many significant figures should its density value have?

BlackZzzverrR [31]

Answer:

Explanation:

The mass has 4 sig digits.

The volume has 3 sig digits

The density is = 11.50/9.03 = 1.2735

To 3 sig digits (determined by 9.03) the answer would be 1.27 gram/mL

If you dive out just past the continental slope and look at the living things on the ocean floor which zone are you exploring

mamaluj [8]

Lies just beyond the continental slope is the open ocean zone and it has three subzones namely the epipelagic(sunlit zone), mesopelagic(disphotic zone) and bathypelagic zones(aphotic zone). The oceanic zone covers 65% of the ocean's water and where different types of terrains can be found. From deep trenches, deep sea volcanoes and basins. A variety of sea creatures can also be found on each subzone.
