Cl₂0₅ + H₂O → 2HCIO₃
2Fe(OH)₃ → Fe₂O₃ + 3H₂O
Further explanationGiven
Chemical equations
Required
The balanced combination equation
Solution
There are several types of reactions that can occur
Synthesis/combination : 2 elements combine to form a single product
A + B⇒AB
Decomposition: One compound breaks down into 2 components
AB⇒A + B
Decomposition is the reverse of syntesis reaction
A balanced equation shows that the number of atoms from the reactant and product sides is the same
The chemical equations that fulfill the two things above (combined and balanced reactions) are:
Cl₂0₅ + H₂O → 2HCIO₃
2Fe(OH)₃ → Fe₂O₃ + 3H₂O
Answer:
Cl2O5 + 3H2O ⟶ HClO3 is the correct answer

in a 35.0 L tank of N2O3 at STP, how many molecules are there?
Answer:
[tex]9.40x10^{23}molecules[/tex]
Explanation:
Hello!
In this case, since we are given the volume of N2O3 and pressure and temperature for the STP (1.00 atm and 273.15 K), we can compute the moles, considering the ideal gas equation as shown below:
[tex]PV=nRT\\\\n=\frac{PV}{RT} \\\\n=\frac{1atm*35L}{0.08206\frac{atm*L}{mol*K}*273.15K}\\\\n=1.56mol[/tex]
Now, by using the Avogadro's number it is possible to compute the molecules of this case in 1.56 moles:
[tex]molecules=1.56mol*\frac{6.022x10^{23}}{1mol} =9.40x10^{23}molecules[/tex]

1.Chlorobenzene, C6H5Cl, is used in the production of chemicals such as aspirin and dyes. One way that chlorobenzene is prepared is by reacting benzene, C6H6, with chlorine gas according to the following BALANCED equation.
C6H6 (l) + Cl2 (g) C6H5Cl (s) + HCl (g)a.
What is the theoretical yield if 45.6 g of benzene react?
Answer:
[tex]m_{C_6H_5Cl}=65.7gC_6H_5Cl[/tex]
Explanation:
Hello!
In this case, according to the given balanced chemical reaction:
[tex]C_6H_6 (l) + Cl_2 (g) \rightarrow C_6H_5Cl (s) + HCl (g)[/tex]
We can see there is 1:1 between benzene and chlorobenzene as the relavant product; thus, since the molar mass of benzene is 78.11 g/mol and that of chlorobenzene is 112.55 g/mol, the theoretical yield for this reaction turns out:
[tex]m_{C_6H_5Cl}=45.6gC_6H_6*\frac{1molC_6H_6}{78.11gC_6H_6 }*\frac{1molC_6H_5Cl}{1molC_6H_6}*\frac{112.55gC_6H_5Cl}{1molC_6H_5Cl} \\\\m_{C_6H_5Cl}=65.7gC_6H_5Cl[/tex]

Write a paragraph that explains diffusion and osmosis and how it relates to the circulatory system. Each sentence should be typed in the appropriate color.
It should include an introductory sentence that restates the question. A sentence that explains diffusion. A sentence that explains osmosis and at least 2-3 sentences that explain the relationship between diffusion, osmosis and the circulatory system. And, lastly, a conclusion sentence.
Materials are transferred between individual cells and their internal environment through the cell membrane by diffusion, osmosis, and active transport. During diffusion and osmosis, molecules move from a higher concentration to a lower concentration. Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. This would be the diffusion.

Determine the [OH-] concentration of a 0.123 M Sr(OH)2 solution at 25°C
Answer:
0.246M
Explanation:
0.123M x 2 = 0.246M
Due to Sr(OH)2 has the coefficient of 2.
The [OH⁻] concentration for 0.123 M Sr(OH)₂ solution at 25°C is 0.246M
What is Concentration ?The amount of a solution's solute to either the solvent or the entire solution is called Concentration.
The most common way to express concentration is in terms of mass per unit volume.
The solute concentration, on the other hand, can be expressed in moles or units of volume.
We assume
Sr(OH)2 is a strong base, such that
Sr(OH)₂(s) + H₂O(l) −−−→Sr²⁺(aq)+2OH⁻aq)
The [OH⁻] concentration for 0.123 M Sr(OH)₂ solution at 25°C
= 2 * 0.123
= 0.246 M
As two [OH⁻] are being produced by Sr(OH)₂ .
The [OH⁻] concentration for 0.123 M Sr(OH)₂ solution at 25°C is 0.246M.

Determine the number of atoms of O in 58.3 moles of Na₂Cr₂O₇.
Answer:
2457.58×10²³ atoms of oxygen
Explanation:
Given data:
Number of moles of Na₂Cr₂O₇ = 58.3 mol
Number of atoms of oxygen = ?
Solution:
First of all we will calculate the number of moles of oxygen in 58.3 moles of Na₂Cr₂O₇.
1 mole of Na₂Cr₂O₇ contain 7 moles of oxygen.
58.3 mol × 7 = 408.1 mol
Number of atoms of oxygen:
1 mole contain 6.022×10²³ atoms
408.1 mol × 6.022×10²³ atoms / 1 mol
2457.58×10²³ atoms

Balance the following chemical reaction: _NaOH + _H2SO4 ----->_Na2SO4 +_H20
Already balanced.
NaOH + 2H2SO4 ----> 2 Na2SO4 + H2O
2 NaOH + H2SO4 ----> Na2SO4 + 2H2O
2 NaOH + 2 H2S04 -----> 2 Na2SO4 + 2 H20
Answer:
Sodium Hydroxide + Sulfuric Acid = Sodium Sulfate + Water
2NaOH + H2SO4 → Na2SO4 + 2H2O
Explanation:
To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.
Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
Ionic charges are not yet supported and will be ignored.
Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
Compound states [like (s) (aq) or (g)] are not required.
You can use parenthesis () or brackets [].

Which of the following statements best describes a limiting reactant? (5 points)
Answer:
The limiting reagent is the reactant that is completely used up in a reaction, and thus determines when the reaction stops. From the reaction stoichiometry, the exact amount of reactant needed to react with another element can be calculated.
Explanation:
The Reactant That Limits The Rate (or Speed) Of A Chemical Reaction. The Reactant That Can Produce The Greatest Amount Of Product.
The reactant that is used up before the others best describes a limiting reactant.
What is reactant?Reactant is a starting material in a chemical reaction.
What is limiting reactant?A limiting reactant is the reactant that is used up first and prevents more product from being made. When the limiting reactants are completely used up, then the reaction stops and no further products will be produced.Hence, the reactant that are used up before the others best describes a limiting reactant.

How much energy is required to heat up a Styrofoam cup from 25oC to 40oC? The mass of the cup is 20 grams and the specific heat capacity of Styrofoam is 1.1 J/(g *oC). Group of answer choices
Answer:
[tex]Q=330J[/tex]
Explanation:
Hello!
In this case, since the energy involved during a heating process is calculated as shown below:
[tex]Q=mC(T_2-T_1)[/tex]
Whereas we consider the mass, heat capacity and temperature; we are able to plug in the given data to obtain:
[tex]Q = 20g*1.1\frac{J}{g\°C}(40\°C-25\°C)\\\\Q = 330J[/tex]
Best regards!
PLEASE PLEASE HELP ASAP!
Answer:
Q = 146.25 J
Explanation:
Given that,
The mass of 10 copper pennis = 25 grams
It warm up from 23°C to 38°C.
The specific heat capacity of copper is 0.39 J/g°C
We need to find the energy absorbed by the pennies. The expression for the energy absorbed is given by :
[tex]Q=mc\Delta T\\\\Q=25\times 0.39\times (38-23)\\\\Q=146.25\ J[/tex]
So, 146.25 J of energy is absorbed by the pennies. Hence, this is the required solution.
