How many grams of zinc chloride does it take to react to 45 grams of aluminum?
To determine how many grams of zinc chloride (ZnCl₂) are needed to react with 45 grams of aluminum (Al), we first need to look at the balanced chemical equation for the reaction, which is: [ 2Al + 3ZnCl₂ \rightarrow 2AlCl₃ + 3Zn ] From the equation, 2 moles of aluminum react with 3 moles of zinc chloride. The molar mass of aluminum is approximately 27 g/mol, so 45 grams of aluminum corresponds to about 1.67 moles of Al. Thus, we need 2.5 moles of ZnCl₂ (since 1.67 moles Al will require 2.5 moles ZnCl₂). The molar mass of ZnCl₂ is about 136.3 g/mol, so 2.5 moles of ZnCl₂ would weigh approximately 340.75 grams.
What is the oxidation number of ZnCl?

What coefficient is needed to balancerhe equation Zn HCI ZnCI2 H2?
To balance the equation Zn + HCl → ZnCl₂ + H₂, you need a coefficient of 2 in front of HCl. The balanced equation is: Zn + 2 HCl → ZnCl₂ + H₂. This ensures that the number of each type of atom is the same on both sides of the equation.
Calculate the number of moles in 0.525 g of AgCl.?
moles= mass/Mr so 525 divided by the Mr of ZnCl-2 Mr of ZnCl-2= (Ar of Zn= 65.37)+(2 x Ar of Cl= 2 x 35.5= 71) = 136.37 moles= 525/136.37 = 3.85 moles to 3 significant figures. (in grams) divide the answer by 1000 to get mg so 3.85/1000= 0.00385 moles
What are the products of the chemical reaction that occurs when zinc metal is added to an aqueous solution of hydrochloric acid?
When zinc metal (Zn) is added to an aqueous solution of hydrochloric acid (HCl), a chemical reaction occurs, producing zinc chloride (ZnCl₂) and hydrogen gas (H₂). The balanced equation for the reaction is: Zn + 2HCl → ZnCl₂ + H₂↑. The hydrogen gas is released as bubbles, and zinc chloride remains dissolved in the solution.
What is the Conclusion of experiment determination of the formula unit of zinc chloride?
The conclusion of the experiment to determine the formula unit of zinc chloride typically confirms that the empirical formula is ZnCl₂. This is established by determining the molar ratio of zinc to chloride ions through stoichiometric calculations based on mass measurements. The experiment demonstrates that each zinc ion combines with two chloride ions, validating the formula unit of zinc chloride as ZnCl₂.
What is the balanced equation for zinc and HCl?
The balanced equation for the reaction between zinc and hydrochloric acid (HCl) is: Zn + 2HCl -> ZnCl2 + H2.
What happens when zinc sulphate is added to barium chloride?
When zinc sulfate (ZnSO₄) is added to barium chloride (BaCl₂), a double displacement reaction occurs, resulting in the formation of barium sulfate (BaSO₄) and zinc chloride (ZnCl₂). Barium sulfate is insoluble in water and precipitates out as a white solid. The overall reaction can be represented as: ZnSO₄ + BaCl₂ → BaSO₄ (precipitate) + ZnCl₂. This reaction is often used in laboratory settings to demonstrate precipitation reactions.
Write the correct coefficients (in correct order) after this equation has been balanced. Al and Euml and Atilde(CO and Euml and Auml) and Euml and Auml plus ZnCl and Euml and Atilde and aelig ZnCO and?
To balance the chemical equation involving aluminum (Al), carbon monoxide (CO), and zinc chloride (ZnCl₂), we first need to identify the correct products. Assuming the equation is meant to represent a reaction between aluminum, carbon monoxide, and zinc chloride to form zinc, aluminum oxide, and carbon dioxide, the balanced equation would typically yield coefficients like: 4 Al + 3 ZnCl₂ + 6 CO → 4 Zn + 2 Al₂O₃ + 6 CO₂. Thus, the coefficients in order are 4, 3, 6, 4, 2, 6.
