Que cantidad de agua sera necesaria agregar a 25 gramos de sulfato de cobre II para preparar una solución al 15% m/m?
Answer:
141.7 de Agua deben ser adicionados para preparar la solución deseada
Explanation:
El %m/m se define como la masa de soluto (En este caso, sulfato de cobre) en 100g de solución (Sulfato de cobre + Agua):
%m/m = Masa soluto / Masa soluto + Masa Agua *100
Reemplazando con los datos del problema:
15%m/m: 25g CuSO₄ / (25g CuSO₄ + Xg H₂O) * 100
0.15 = 25 /(25+X)
3.75 + 0.15X = 25
0.15X = 21.25
X = 141.7 de Agua deben ser adicionados para preparar la solución deseada
If 0.525 moles of O2 are produced, how many moles of KClO3 are decomposed?
Answer:
B. 0.35mol KClO3
Explanation:
The balanced equation in this question is given as follows:
2KClO3 → 2KCl + 3O2
Based on the chemical reaction;
2 moles of KClO3 decomposes into 3 moles of O2
If 0.525 moles of O2 are produced, then:
= 0.525 × 2/3
= 1.05/3
= 0.35mol of KClO3 is decomposed.

How many grams of carbon dioxide would 6.0E25 molecules be?
Answer:
4383.28 g
Explanation:
First we'll need to convert molecules into moles, we can do so using Avogadro's number:
6.0x10²⁵ molecules ÷ 6.023x10²³ molecules/mol = 99.62 molesThen we will convert 99.62 moles of carbon dioxide (CO₂) into grams, using its molar mass:
99.62 moles CO₂ * 44 g/mol = 4383.28 gWhich change in pH represents a hundredfold increase in the concentration of hydronium ions
in a solution?
(1) pH 1 to 2
(2) pH 1 to 3

Which set up would correctly complete the work for determining how many moles of NaOH will be produced if 10.5 grams of water (H2O) is used?
Answer:
B: 2 mol NaOH/2 mol H2O
Explanation:
The reaction equation is;
H2SO4 + 2NaOH = Na2SO4 + 2H20
Now, to know how many moles of NaOH will be produced for 10.5 grams of water (H2O) used, and since the molar mass of H2O is 18.02 g/mol and number of moles attached to H2O and NaOH in the reaction are both 2 we will have;
10.5g H2O × 1 mol H2O/18.02 g H2O × 2 mol NaOH/2 mol H2O
Thus correct answer is option B

Which of the following is not an example for electroplating? A Tin cans for storing food
B Chromium used on bath taps to get shiny appearance
C Copper used for making electrical wires
D To protect iron objects used in machineries, from corrosion
If you answer you will get brainiest
Please answer and thank
Answer:
C. Copper used for making electrical wires
Explanation:
When a coating of a particular metal is applied on another metal, the process is termed as electroplating. The process is carried by the process of electro-deposition. This process is carried on in order to enhance the quality of the objects manufactured. The coating helps in resistance and provides an attractive appearance to the object.
Option C. is not an example of electrocoating because on the copper wires no other metal coating is done. In all the other three options, coating has been done on the object.

_ Na+Cl 2 -> _NaCl
reactant side number of atoms?
Na = ?
Cl = ?
Product side number of atoms?
Na = ?
Cl = ?
what is the final equation?
_ Na+Cl 2 -> _NaCl
Answer:
2Na+Cl2 -> 2NaCl
Explanation:
1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)
Na = 1
Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)
Na = 1
Cl = 1
We need to have 2 Cl on the product side
1Na+1Cl 2 -> 2NaCl
Now we need 2 Na on the reactants side
The final equation is
2Na+Cl2 -> 2NaCl
Now it is balanced
Na = 2
Cl = 2
--
Na = 2
Cl = 2
Equilibrium constant Kp for the reaction P4(s) + 6Cl2(g) 4PCl3(l) Kp = 1/ P6Cl2 Kp = P4Cl3/ P6P4 Kp = P4Cl3/ (P6P4) (P6Cl2) Kp = 1/ (P6P4) (P6Cl2)
Answer: [tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressuure of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_p[/tex]
For the given chemical reaction:
[tex]P_4(s)+6Cl_2(g)\rightarrow 4PCl_3(l)[/tex]
The expression for [tex]K_p[/tex] in terms of gaseous is written as:
[tex]K_p=\frac{1}{[p_{Cl_2}]^6}[/tex]
