Which balance equation represents a single replacement reaction

Answers

Answer: A single replacement reaction looks sort of like this

A + BC —> AC + B

Explanation: It would be a LOT more helpful for us if you had provided the answer choices for this question, but I'll try to help by explaining WHAT single-replacement reactions are.

Single-replacement reactions are reactions in which one ion displaces another to form a new compound . One reactant is an element; one reactant is a compound . One product is an element; one product is a compound . The reactant element is part of the compound product .

why is it important to know the number of valence electrons in an atom?

Answers

Answer:

Valence electrons are the electrons in the outermost energy level of an atom — in the energy level that is farthest away from the nucleus. Being able to determine the number of valence electrons in a particular atom gives you a big clue as to how that atom will react.

Answers

Answer:

Smaller than the object

Real

Upside down

Explanation:

The image formed by a convex lens will always be real and smaller. The image formed is smaller than the object, real ,upside down and right side up. Hence, options 1,2,3 and 5 are correct.

What is convex lens?

Convex lens is a type of lens, in which one at least one side is curved outside. These lenses have the ability to focus an outside light beam to a spot on the opposite side by converging it.

The focal length of the convex lens is the distance from the lens's center to this point, which is known as the focus. On the other hand, a plano-convex lens has one surface that is flat and the other that is convex.

Convex lenses cause light from an item to bend, creating an upright, smaller, and inverted picture of the original object. As a result, the candle in this instance will be smaller, upside down, and actual.

Answers

Answer:

ATP

Explanation:

it is made by breaking glucose down

Answer:

Once the last phosphate group is removed from the ATP molecule by hydrolysis, it will form ADP plus inorganic phosphate. ADP is a lower energy molecule. The release of energy during hydrolysis of ATP can be harnessed by the cell to do work. Living things continuously use ATP but it is renewable and can be recycled.

An unknown substance visually appears to be a white powder. The substance is analyzed in the laboratory and its melting point is found to be 264 °C.
What can you predict about the intramolecular forces and intermolecular forces in this substance?

Answers

Answer:

See explanation

Explanation:

The substance under analysis must be a polar organic substance of high molecular mass. We must remember that as the magnitude of dispersion forces increases with increase in molecular mass, the melting point increases accordingly. Also polar organic substances have very high melting points due to the presence of polar bonds in the molecule..

Hence the intramolecular forces in the substance are covalent bonds while the intermolecular forces are both dispersion forces and dipole forces.

The substance may likely be 1,2,3,4,6,7,8-Heptachlorodibenzo-p-Dioxin which a white powder and melts at 264 °C.

what coefficients used to balance chemical equation below? ___ Ag2O ----> ____ Ag + ___ O2

A 2,4,1
B 2,2,2
C 2,1,2
D 1,1,1

Answers

I believe the correct answer is C it would make the value of the left side equal to 4 and the value to the right side also equal to 4

The coefficients used to balance the chemical equation given in the question are 2, 4, 1 (Option A)

What is a chemical equation?

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

How to balance the equation

Ag₂O —> Ag + O₂

There are 2 atoms of O on the right side 1 on the left. It can be balance by writing 2 before Ag₂O as shown below

2Ag₂O —> Ag + O₂

There are 4 atoms of Ag on the left side and 1 atom on the right side. It can be balance by writing 4 before Ag as shown below

2Ag₂O —> 4Ag + O₂

Now, the equation is balanced.

Thus, the coefficients are: 2, 4, 1

The reaction of HCl with NaOH is represented by the equation
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
What volume of 0.417 M HCl is required to titrate 11.9 mL of 0.151 M NaOH?
a. 4.3 mL
b. 2.39 mL
c. 0.749 mL
d. 32.8 mL
e. 11.9 mL

Answers

Answer:

a. 4.3 mL

Explanation:

Step 1: Write the balanced neutralization reaction

HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)

Step 2: Calculate the reacting moles of NaOH

11.9 mL of 0.151 M NaOH react.

0.0119 L × 0.151 mol/L = 0.00180 mol

Step 3: Calculate the reacting moles of HCl

The molar ratio of HCl to NaOH is 1:1. The reacting moles of HCl are 1/1 × 0.00180 mol = 0.00180 mol.

Step 4: Calculate the volume of 0.417 M HCl that contains 0.00180 moles of HCl

0.00180 mol × (1000 mL/0.417 mol) = 4.3 mL

The volume of HCL will be "4.3 mL".

According to the question,

Mass,

[tex]M_1 = 0.417[/tex][tex]M_2 = 11.9[/tex]

Volume,

[tex]V_1 = ?[/tex][tex]V_2 = 0.151[/tex]

As we know the relation,

→ [tex]M_1V_1 = M_2 V_2[/tex]

or,

→      [tex]V_1 = \frac{M_2 V_2}{M_1}[/tex]

By substituting the values, we get

            [tex]= \frac{11.9\times 0.151}{0.417}[/tex]

            [tex]= \frac{1.7969}{0.417}[/tex]

            [tex]= 4.3 \ mL[/tex]

Thus the above answer is right.

To measure the amount of nickel in some industrial waste fluid, an analytical chemist adds 0.110 M sodium hydroxide (NaOH) solution to a 25.0 g sample of the fluid and collects the solid nickel(I) hydroxide (Ni (OH2) product. When no more Ni(OH)2 is produced, he filters, washes and weighs it, and finds that 343. mg has been produced The balanced chemical equation for the reaction is: Ni2+(aq) + 2NaOH(aq) Ni(OH)2(s) + 2 Na.
What kind of reaction is this?
a. precipitation
b. acid-base
c. redox

Answers

Answer:

a. precipitation

Explanation:

In the reaction:

Ni²⁺(aq) + 2NaOH(aq)→ Ni(OH)₂(s) + 2 Na⁺

Nickel is precipitated as Ni(OH)₂ producing Na⁺ ions.

In a precipitation two soluble ions react with each other to produce an insoluble salt.

In our problem, Ni²⁺ is reacting with OH⁻ to produce Ni(OH)₂, an insoluble salt

The reaction is a precipitation

In an acid-base reaction, an acid reacts with a base to produce water and a salt. In this problem is a base reacting (NaOH) but there are no acids in the reaction.

And in a redox reaction an ion is been oxidized whereas the other is been reduced (Loosing electrons and gaining electrons).

As you can see, Ni²⁺ still with oxidation number of 2+ in Ni(OH)₂ and Na⁺ is always +1-. Thus, this is not a redox reaction.

Answer:

Products

Explanation:

Reactants → Products

Chemical reactions are characterized by the formation of new products, and the making and breaking off strong chemical bonds.

Answer: They are the PRODUCTS of the reaction.

Explanation: In a chemical reaction, there are the REACTANTS and the PRODUCTS.

The reactants are the "ingredients" in the chemical formula. They are what are being chemically combined in a way.

The products are the "meal," or what the reactants combined to create.

For example, when creating salt or NaCl, this is essentially the formula:

Na + Cl = NaCl

In this formula, Na (sodium) and Cl (chlorine) are the reactants. NaCl (sodium chloride, aka salt) is the product.

A solution contains 9.25x103 M copper(II) nitrate and 1.40x102 M manganese(II) acetate. Solid potassium carbonate is added slowly to this mixture.
A. What is the formula of the substance that precipitates first?
B. What is the concentration of carbonate ion when this precipitation first begins?

Answers

Answer:

Explanation:

Concentration of Cu⁺² = 9.25 x 10³ M

Concentration of Mn⁺² = 1.4 x 10² M

solubility product of copper carbonate = 7.08 x 10⁻⁹

solubility product of manganese  carbonate = 2.24 x 10⁻¹¹

solubility product of later is less so carbonate of manganese will come out first .

B )

[ Mn⁺² ] [ CO₃⁻² ] = 2.24 x 10⁻¹¹

1.4 x 10²  [ CO₃⁻² ] = 2.24 x 10⁻¹¹

[ CO₃⁻² ] = 1.6 x 10⁻¹³ .

the concentration of carbonate ion when this precipitation first begins

= 1.6 x 10⁻¹³ M .
