Answer:
4.43 g Cl₂
Explanation:
To find the mass of Cl₂, you need to (1) convert moles HCl to moles Cl₂ (via the mole-to-mole ratio from equation coefficients) and then (2) convert moles Cl₂ to grams (via the molar mass). It is important to arrange the conversions/ratios in a way that allows for the cancellation of units. The final answer should have 3 significant figures like the given value.
4 HCl(g) + O₂(g) -----> 2 Cl₂(g) + 2 H₂O(g)
^ ^
Molar Mass (Cl₂): 2(35.453 g/mol)
Molar Mass (Cl₂): 70.906 g/mol
0.125 moles HCl 2 moles Cl₂ 70.906 g
-------------------------- x ---------------------- x ------------------- = 4.43 g Cl₂
4 moles HCl 1 mole
Write an equation to represent the following reaction:
Borax is heated with CoO
The equation of the reaction is; B2O3 + CoO -----> Co(BO2)2.
What is a reaction?The term chemical reaction has to do with the interaction between reactants in order to yield products. We know that when a chemical reaction occurs, the reactants are rearranged to form the products.
Now the first step in this reaction is that the Borax is heated to form boric anhydride (B2O3). Thus compound now reacts with cobalt II oxide as follows; B2O3 + CoO -----> Co(BO2)2.

The sp of pbbr2 is 6. 60×10−6. what is the molar solubility of pbbr2 in pure water?
Ksp of PbBr₂ is 6.60 × 10⁻⁶. The molar solubility of PbBr₂ in pure water is 0.0118M.
Ksp or Solubility Product Constant is an equilibrium constant for the dissociation in an aqueous solution.
Molar solubility (S) is the concentration of the dissolved substance in a solution that is saturated.
Let the molar solubility be S upon dissociation.
PbBr₂ or Lead Bromide dissociates in pure water as follows:
PbBr₂ ----------> Pb⁺² + Br⁻
S 2S
Ksp = [Pb⁺²] [ Br⁻]
Ksp = (S) (2S)²
Ksp = 4S³
6.60 × 10⁻⁶ = 4S³
S = 0.0118M

Which are properties of all metals (except hg)? i. good conductors of heat and electricity ii. easily formed into sheets or wires iii. chemically unre
The properties of all metals are "good conductors of heat and electricity".
Metals are excellent heat or electricity conductors and were malleable, ductile materials that may be pulled into wire and pounded into sheets. Apart from mercury, which appears a liquid at ambient temperature, most metals have solids with a distinctive silvery shine.
Due to the metals' atoms' ability to create a matrix across which outside electrons could easily travel, metals make good electrical and thermal conductors. The positive nuclei of the connecting metal ions are surrounded by a sea of electrons rather than orbiting their individual atoms.
Therefore, the properties of all metals are "good conductors of heat and electricity".

An aqueous solution of a strong base has a pH of 10. 220 at 25°C then concentration of the base if the base is
(a) LiOH = 1.66×[tex]10^{-4}[/tex] M
(b) [tex]Ba(OH)_{2[/tex] = 3.32×[tex]10^{-4}[/tex]M
Calculation ,
For calculation of concentration of the LiOH and [tex]Ba(OH)_{2[/tex] first we have to calculate pOH of the solution.

Benzene is often produced as a side product during grignard reactions using phenylmagnesium bromide. how can its formation be explained? give a balanced equation for its formation
Benzene is produced as a side product when water react with phenyl magnesium bromide during Grignard reactions.
What is Grignard Reaction ?The Grignard reaction involves an R-Mg-X, a carbon chain bound to a magnesium halide, used to form alcohols by attacking carbonyls such as in aldehydes or ketones.
Here R act as a nucleophile and Mg-X act as a electrophile. Instead of attacking carbonyl, which is present in the reaction, the benzene ring will attack water molecules present around, grabbing a H⁺ and pushing away MgBr .
The required reaction is :
PhMgBr + H₂O → Ph-H + MgBrOH

The penny coin was removed from circulation in Canada
In February of 2014. The United States may soon do the
same. The major reason for this move was the rising value
of copper metal. When copper’s value increased, pennies
were produced as a zinc slug with a thin layer of copper
plated over top. Zinc reacts readily with hydrochloric acid,
while copper does not. A triangular file is used to nick the
edge of a penny to expose the zinc slug below the layer
of copper. The zinc reacts with the acid releasing bubbles
from the nicked area until nothing remains but a thin shell
of copper. If 0.948 L of hydrogen gas is collected over water
at 20.0°C and a total pressure of 752 mm Hg, determine the
percentage by mass of the copper in the 2.586 g penny.
As a result, the dry gas volume at STP is 45.58 cm 3.
Water vapor is present in the gas. Since H2 is created during the reaction and water vapor is irrelevant when determining the equivalent weight, we only need the dry gas. As a result, the volume of H2 gas can be calculated using the ideal gas law.
P 1 = 750 mm Hg, 14 mm Hg, 736 mm Hg V = 50 cm 3 T = 17 0 C = 290 K
P = 760mmHg, V =?cm3, T = 0 0 and C = 273K.
The Gas equation follows.
P 1V 1/ T1 = P 2V 2/ T2
290/73650 = 273/760V 2

What is the boiling point of a solution consisting of cyclohexane (c6h12) dissolved in benzene if the freezing point of this solution is 0. 0°c?
The boiling point of a solution consisting of cyclohexane (c6h12) dissolved in benzene if the freezing point of this solution is 0. 0°c is 80.9°C.
When a solute and a solvent are combined to form a liquid homogeneous mixture or solution, the properties that result are different from those of the pure substances. As a result, we can find a freezing point depression, boiling point elevation, and a few other cooperative properties, but these two are the focus of this article.
Taking into account that the freezing point depression constant solely depends on the solvent (cyclohexane), we can begin by utilizing the freezing point depression to determine the molality of the solution:
[tex]T_{fsolution} - T_{fsolvent} = -m * {K_{fsolvent}[/tex]
0. 0°c - 5.5°c = -m * 20.0 °c
[tex]m = \frac{-5.5}{- 20.0 }[/tex]
m = 0.275 m
The boiling point elevation formula is then used to get the solution's boiling point, which is once more dependent on the solvent's boiling point elevation constant:
[tex]T_{b, solution} - T_{b, solute} = m * Kb_{solvent} \\\\T_{b, solution} - 80.1 = 0.275m + 2.79\\\\T_{b, solution} = 80.9[/tex]

It is important to know if a substance is a molecular compound or an ionic compound because the boiling and freezing points of a solvent are colligative properties, and they depend on the solute particles.
What are molecular and ionic compounds?Molecular compounds are pure things called that are created when atoms are joined by the sharing of electrons. Ionic compounds are formed by transferring electrons between the elements.
It is important to know the type of compounds before predicting because the more the solute particles the more the freezing point and lower the boiling points. And it tells how much amount f solute will be fine in the solvent.
Thus, knowing if a material is a molecular or ionic compound is crucial since a solvent's boiling and freezing temperatures are collaborative features that are dependent on the solute particles.

Which 5-carbon intermediate of the citric acid cycle is converted to a 4-carbon molecule with the release of carbon dioxide?
The alpha- ketoglutarate is the 5-carbon intermediate of the citric acid cycle which converted to a 4-carbon molecule with the release of carbon dioxide
The first decarboxylation reaction in Krebs cycle ( known as citric acid cycle ) is catalyzed by isocitrate dehydrogenase in which one six carbon atoms compound isocitrate is decarboxylated to yield five carbon atom containing alpha ketoglutaric acid.
The alpha- ketoglutarate is the 5-carbon intermediate of the citric acid cycle which is salt of alpha ketoglutaric acid. The last reaction in the citric acid cycle produces a product that is a substrate for the first reaction of the citric acid cycle.

If the dehydration reaction of an alcohol is successful. What changes would be seen in the ir spectrum for the product compared to the starting material?
If the dehydration reaction of an alcohol is successful. The changes would be seen in the IR spectrum for the product compared to the starting material are as,
The O-H and C-O band is disappear from stating materialThe addition of a C-C double bond band in the product.In dehydration reaction of alcohol ( O-H and C-O bond ) contain , the water molecule ( [tex]H_{2}O[/tex] ) is release from the reactant and C-C double bond is form which is known as alkene in the product .
The reactant and product have different structure. To determine the structure of the compound IR spectroscopy is used. In IR spectrum the peak corresponds to 3400-3600 cm is missing in the product of dehydration reaction of an alcohol. It means O-H band is disappear from stating material.
