Answer:

<em>An electrical circuit is an unbroken path along which an electrical current occurs and/or will pass. The basic electrical circuit consists of a power supply, two conductive wires (one end of each being connected to each cell terminal) and a small light to which the free ends of the wires leading out of the cell are attached. If the links are made right, the circuit will "close"</em>

How to balance chemical equations
Sonbull [250]
To balance a chemical equation, you want the same amount of elements to equal the same on both sides.

Step1. Write equation out
[CH4 + Cl2 ---> CCl4 + HCl] 
C:1; H:4; Cl:2      C:1; H:1; CL:5   /// Cl = 5 since 4Cl +  1Cl

The Carbon element is balanced, but Hydrogen isn't.
 So to balance it we will add a coefficient behind HCl, so now 

[CH4 + Cl2 ------> CCl4 + 4HCL]
C:1; H:4; Cl:2      C:1; H:4; CL:8 ///// Carbon and hydrogen are balanced, but now Chlorine is not. Now we balance that element by addind a coefficiant behind CL2////

[CH4 + 4Cl2 -----> CCl4 + 4HCl]
C:1; H:4; Cl:8      C:1; H:4; CL:8  ///// So now that we added a 4*Cl2, it equals to Cl:8. So now what most people want to see is if every element is at its lowest balance, so we see if we can any coefficient lower. Just like simplifying if possible.

Using complete sentences, explain how to predict the products and balance the reaction between sulfuric acid and potassium hydro
Dahasolnce [82]

The product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.

<h3>What is the reaction between sulfuric acid and potassium hydroxide?</h3>

The result will be, H+ from H₂SO₄ reacts with OH- from KOH to generate H₂O. Also, K+ reacts with SO₄²⁻ to create K₂SO4₄

As a result, the balanced equation will be:

\rm H_2SO_4 + 2KOH --- > K_2SO_4 + 2H_2O

Thus, the product(s) of the reaction are to be determined given the reactants, sulfuric acid and potassium hydroxide. Sulfuric acid is an acid, whereas potassium hydroxide is a basic. The results of this neutralizing process are salt and water.

Pretend you are an uncooked egg; now describe what happened to you when you were placed in a pot of boiling water. Be sure to in
aniked [119]

Answer:The molecules in a raw egg absorb the heat energy, they use this energy to change shape

Such a chemical reaction is said to be endergonic, which means 'energy in'.

Egg molecules will never undergo these reactions without the input of energy (usually in the form of heat)

I hope this helps, if not, let me know :)

On a container of chicken broth you notice the instructions to ""shake well before serving."" Which of the following best descri
prohojiy [21]

Answer:

The correct option is: D. A suspension

Explanation:

A suspension is a type of heterogeneous mixture in which solid particles are suspended through out the bulk of the solvent through mechanical agitation. The solid phase is also known as the internal phase and the solvent is known as external phase. In a suspension, the solid particles are generally larger than one micrometer and thus are unable to dissolve in the medium. The solid particles of a suspension are large enough to get precipitated.

<u>Therefore, in the given situation, the chicken broth is </u><u>a suspension</u><u> </u>as the contents or solid particles of the container needs to be suspended in the solvent by shaking to prevent sedimentation.

Tems11 [23]

Answer:

Following are the explanation to this question:

Explanation:

The salts of carboxylate are named by the writing, which is also named as the creation of the first, which is followed by the name of the carboxylic acid were '-ic' of the acid end and replaced by the 'ate'.

Following are the description of the given reaction:

In reaction A:

2-Bromopropanoic acid= C_3H_5BrO_2

C_3H_5BrO_2+NaOH⇄ C_3H_4BrNaO_2 +H_2O

The IUPAC name is Sodium-2-Bromopropanate

In reaction B:

2-Methylhexanoic acid= C_7H_{14}O_2

C_7H_{14}O_2+NaOH⇄ C_7H_{13}NaO_{2}+H_2O

The IUPAC name is Sodium-2-Methyl hexanoate
