2018年2月25日 · See the explanation below.. H2+ Cl2 --------> 2HCl The rate law can be concluded from this equation: R = k {H2} {Cl2} where: k is the rate constant, {H2} is the concentration of hydrogen gas and {Cl2} is the concentration of chlorine gas; all are to the power one as mentioned in the balanced equation. So, the order would be: 1. First with respect to …

2016年11月7日 · Well, D is not even true. H_2(g) + Cl_2(g) rarr 2HCl(g) In this reaction, 2xxH-Cl bonds are formed, and 2 elemental bonds are broken (i.e. 1xxH-H, and 1xxCl-Cl). And so the number of bonds formed versus bonds broken are EQUAL.

2014年5月31日 · To complete your equation, H_2 + Cl_2 --> 2HCl. The mole ratios are 1 : 1 : 2. The mole ratios (fancy term is stoichiometry) are simply the numbers in front of each chemical formula which are used to balance the equation. In this case, the equation reads "one mole of hydrogen reacts with one mole of chlorine to make two moles of hydrogen chloride". A …

2017年11月5日 · In the reaction H2+Cl2~2HCl.so A) hydrogen is oxidized B) chlorine is reduced C) chlorine is an oxidizing agent D)all of the above?

2017年3月30日 · 4 moles of HCl are produced The ratio at which the compounds react with each other are displayed in a chemical reaction as the numbers in front of the compounds. For example in this reaction: 1 H_2 molecule reacts with 1 Cl_2 molecule Forming 2 HCl molecules. In chemistry moles are used as a handy number of a certain amount of stuff. You can compare …

2014年5月13日 · This reaction is the synthesis of Ammonia using Nitrogen and Hydrogen gas. N + H -> NH_3 We must remember that Nitrogen and Hydrogen are both diatomic molecules in their standard gas form. This adjusts the equation to N_2 + H_2 -> NH_3 Now we need to adjust coefficients in order to balance the atoms on each side of the equation. Currently we have 2 …

2016年5月30日 · This is quite a difficult question in that we have to make assumptions: I think the answer is B H_2(g) + Cl_2(g) rarr 2HCl(g) +Delta_1 H_2(g) + Cl_2(g) rarr 2HCl(l) +Delta_2 The difference between Delta_1 and Delta_2 is the process: 2HCl(l) + Deltararr2HCl(g) Energy is used to boil the liquid. Delta_2 as written should be larger than Delta_1 (i.e. when the gas is …

Exothermic reaction is a reaction that releases heat. Examples are: - combustion - rusting-nuclear fission - acid/base neutralization

2016年6月25日 · "HCl"_ ((aq)) + "H"_ 2"O"_ ((l)) -> "H"_ 3"O"_ ((aq))^(+) + "Cl"_ ((aq))^(-) Hydrochloric acid, "HCl", is a strong acid, so right from the start you should expect it ...

2014年6月10日 · Using the equation DeltaG = DeltaH -TDeltaS Where DeltaG is the free energy change (in kJ mol^(-1)) DeltaH is the enthalpy change (in kJ mol^-1) T is the temperature of the reaction, in Kelvin and DeltaS is the entropy change (in kJ K^(-1) mol^(-1)) The enthalpy change can be calculated using a Hess cycle if you don' know it, using enthalpy changes of other …
