Answer: C) the rate of forward reaction is not equal to the rate of backward reaction. This should be the answer.
Explanation:
When Svante Arrhenius first proposed his acid base theory, he was a doctoral candidate. His professors thought his ideas were unfounded. Within a decade, the Arrhenius theory of acid base was widely accepted and praised within the scientific world. Arrhenius defined acids as compounds having an ionizable hydrogen and bases as compounds with ionizable hydroxides. Eventually scientists adopted a broader theory which includes more compounds to define acids and bases. The Bronsted-Lowry acid base theory defines an acid as a _______ and a base as a ______________.
Answer:
proton donar
proton acceptor
Explanation:
From the given information of the question, Arrhenius acid and base concept is explained, from which a better term to define an acid and base is defined, known as The Bronsted-Lowry acid base theory.
According to The Bronsted-Lowry acid base theory -
An acid is the species which can readily donate a proton, where as, a base is the species, which can readily accept a proton.
Hence, the correct answer is as follow -
proton donar
proton acceptor
Answer:

definition of atomic number
The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons.
Answer:
its basically represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table

Calculate the mass of 1.5 moles of calcium atoms.
NA=6x 1023
Mass=
g give your answer to two significant figures.
Answer:
60g
Explanation:
The molar mass of a substance (Atom or molecule) is defined as the mass in grams that 1 mole of substance (6x10²³ particles of this substance) weighs. Using the periodic table of elements we can know the molar mass of each atom.
For example, the molar mass of Calcium is 40.078g / mol.
That means the mass of 1.5 moles of calcium atoms must be:
1.5 moles * (40.078g / mol) =
60gStem cells can differentiate into how many types of body cells?
Balance the following equation: AlCl3 + Cs --> CsCl + Al
Group of answer choices
A.2, 6, 6, 2
B.1, 3, 3, 1
C.3, 1, 3, 1
D.2, 3, 1, 3
Answer: The balanced equation is [tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.
For example, [tex]AlCl_{3} + Cs \rightarrow CsCl + Al[/tex]
Here, number of atoms on reactant side are as follows.
Al = 1Cl = 3Cs = 1Number of atoms on product side are as follows.
Al = 1Cl = 1Cs = 1To balance this equation, multiply Cs by 3 on reactant side and multiply CsCl by 3 on product side.
Hence, now the equation will be as follows.
[tex]AlCl_{3} + 3Cs \rightarrow 3CsCl + Al[/tex]
Here, number of atoms on reactant side are as follows.
Al = 1Cl = 3Cs = 3Number of atoms on product side are as follows.
Al = 1Cl = 3Cs = 3Thus, we can conclude that this equation is balanced.

if the solution is acidic, which ion is found in greater concentration?
Answer:
An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water.
The acidic solution indicates the highest concentration of hydrogen or the proton ion in the solution.
What is acidity?Acidity is the measure of the hydrogen ion in the solution by the pH scale and gives the acidic or basic characteristics to the solution.
The concentration of the hydronium or the hydroxide in the solution is a way to determine the acidic basic nature and the pH and pOH of the solution.
Therefore, in an acidic solution hydrogen ions are in the greatest concentration.

You have a gas that has a pressure of 2 ATM and a volume of 10 L. What would be the new volume if the pressure was changed to 1 ATM ?
Answer:
20 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{2 \times 10}{1} = 20 \\ [/tex]
We have the final answer as
20 LHope this helps you
Which of the following is not a force
A. Weight
B. Friction
C. Acceleration
D. Air resistance
Answer:
Acceleration
Explanation:
Acceleration doesn't change one moment to the next, and therefore, doesn't count as a force.
The answer option which is not a force is: C. Acceleration.
What is a force?A force can be defined as a push or pull of an object or physical body, which typically results in a change of motion (acceleration), especially due to the interaction of the object with another.
The examples of a force.In Science, the three (3) most common examples of a force include the following:
WeightFrictionAir resistanceIn conclusion, acceleration is not an example of a force but a change in the rate of velocity of an object with respect to time.

C + 2ZnO → CO2 + 2zn
How many grams of
carbon dioxide will be
produced if 135 grams
of ZnO is completely
reacted?
Answer:
36.5 g CO2
Explanation:
First, Write a Balanced Equation
C + 2 ZnO → CO2 + 2 Zn
Useful Information,
MW of ZnO = 81.41 g
MW of CO2 = 44.01 g
135 g ZnO x (1 mol ZnO / 81.41 g ZnO) x (1 mol CO2/2 mol ZnO) x ( 44.01 g CO2 / 1 mol CO2 ) = 36.5 g CO2
Determine the volume of the product containing carbon produced when 15.0 g of C2H2 are reacted with an excess of oxygen gas
Answer:
25.8 L
Explanation:
Step 1: Write the balanced equation for the complete combustion of acetylene
C₂H₂ + 2.5 O₂ ⇒ 2 CO₂ + H₂O
Step 2: Calculate the moles corresponding to 15.0 g of C₂H₂
The molar mass of C₂H₂ is 26.04 g/mol.
15.0 g × 1 mol/26.04 g = 0.576 mol
Step 3: Calculate the moles of CO₂ produced from 0.576 moles of C₂H₂
The molar ratio of C₂H₂ to CO₂ is 1:2. The moles of CO₂ produced are 2/1 × 0.576 mol = 1.15 mol.
Step 4: Calculate the volume corresponding to 1.15 moles of CO₂
At standard temperature and pressure, 1 mole of CO₂ occupies 22.4 L.
1.15 mol × 22.4 L/1 mol = 25.8 L

Calculate the energy in joules of a wave particles with a wave length of 6.5×10^6 nm (infrared region)
Answer:
The energy of the wave particle is 3.058 x 10⁻²³ J.
Explanation:
Given;
wavelength of the wave particle, λ = 6.5 x 10⁶ nm = (6.5 x 10⁶) x 10⁻⁹ m
The energy of the wave particle is calculated as;
[tex]E = hf\\\\E = \frac{hc}{\lambda}[/tex]
where;
h is Planck's constant = 6.626 x 10⁻³⁴ J/Hz
c is speed of light = 3 x 10⁸ m/s
[tex]E = \frac{(6.626 \times 10^{-34})(3\times 10^8)}{6.5 \times 10^6 \times 10^{-9}} \\\\E = 3.058 \times 10^{-23} \ J[/tex]
Therefore, the energy of the wave particle is 3.058 x 10⁻²³ J.
Consider the table below that summarizes the types of materials that can block the 3 different types of radiation. Based on the table, at which numbered spot in the table does each type of radiation belong. 1 = beta; 2 = alpha, 3 = gamma
Answer:
D. 1 = gamma; 2 = alpha, 3 = beta
Explanation:
I apologize if this answer is late, but I got answered the question right on my "Types of Radioactive Decay" quiz :)
Hope this is helpful for others! :D
Based on the table, the type of radiation belong from 1 is the gamma rays, from 2 is the aplha rays and from 3 is the beta rays.
What are radiations?During the radioactive decay process, some amount of energy is released in the form of particles and that radiations will known as alpha rays, beta rays and gamma rays.
Gamma ray are mare energetic rays and will shielded by only lead and thick concrete materials.Beta rays are less energetic than gamma rays and will shielded by lead, cloth, paper, wood, aluminium foil and thick concrete materials.Aplha rays have very less amount of energy in it and it will be shielded by all above mention materials.Hence 1 is the gamma rays, 2 is the aplha rays and 3 is the beta rays.
