Chemistry Step-by-Step Solutions: Chemical Reactions

如果你正在学习化学或者是一门学科,需要化学课程的先决条件,那么你知道所需的教材有多贵都可以。为了解决这个问题,化学教育社区开发的开放教育资源免费提供化学课本。然而,尽管免费教科书保持现金的钱包,他们不包括解决方案指南所有的家庭作业的问题。

Luckily, theStep-by-Step Solutionsfeature ofWolfram|Alpha已经收到了你回来!无论您是远程学习或通过视频会议协作,钨|阿尔法帮助您学习和运用解决问题的框架,化学题。manbet万博app步骤一步解决方案提供的分步溶解指南万博体育app怎么样,可以被视为一次一个步骤或全部一次。不仅磨练高效解决问题的能力,同时也将有助于引导挖掘更深的概念可能仍然低迷。

在接下来的几周内,我们将探索一些流行的主题,初中,高中和大学的学生在化学课程和期末考试遇到:化学反应,结构和键合,chemical solutions,最后,量子化学。阅读关于例题中的化学反应和他们一步一步的解决方案!万博体育app怎么样

平衡化学方程式

A fundamental aspect of chemistry isbalancing chemical equations。如果化学方程式是在化学过程所表达的语言,然后平衡化学方程式是相应的语法。步骤一步的溶液引导你通过健全的代数的方法来识别的化学计量系数。

实施例问题

写为铜与硝酸以产生硝酸铜,氮氧化物和水的反应的平衡方程。

Step-by-Step Solution

对于此类问题,只要输入“balance copper + nitric acid -> copper nitrate + nitrogen dioxide + water”。

copper nitrate + nitrogen dioxide + water"" title=""balance copper + nitric acid -> copper nitrate + nitrogen dioxide + water"" width="620" height="1092" class="alignnone size-full wp-image-64318">

After balancing the related chemical equations, the next step in planning a laboratory experiment is computing how much of each reactant must be measured out. To do this, one needs the molar mass for each reactant. Step-by-step solutions are available for the分子量andrelative molecular mass除了molar mass。In all cases, a general framework for solving these types of problems is provided via the Plan step. Details of which formula to use and how to gather the necessary information are provided.

实施例问题

计算硫酸银,Ag的摩尔质量2SO4

Step-by-Step Solution

在这个case, just enter “molar mass silver sulfate”。

“摩尔质量的硫酸银”

块Composition

One way to analyze individual chemicals is to compute and compare the mass and atom percentages. The step-by-step solution provides a general framework for solving this class of problem in the Plan step. Details of the relevant equations, as well as how to compute the necessary intermediate values, are provided. Ways in which you can check your work during the calculations are also available via the “Show intermediate steps” buttons.

实施例问题

Antihemophilic factor is a coagulant with the formula C11794H18314N3220O355S83。什么是它的百分组成?

Step-by-Step Solution

For the answer, just enter “antihemophilic factor elemental composition”。

“抗血友病因子元素组成”

化学转化

Chemical conversionscrop up in nearly every chemistry homework or research problem. As such, step-by-step solutions are available for converting among,mass,volume,moleculesandatoms。Unit conversions and dimensional analysis details are provided.

实施例问题

多少原子处于1.5mM的氢氧化镁溶液的5毫升?

Step-by-Step Solution

To solve this, just enter “convert 5 mL of 1.5 mM magnesium hydroxide to atoms”。

化学计量学

运行化学反应后,人们常常想知道如何反应又通过计算reaction yields。Step-by-step solutions are available for computing the需要的反应物的量and thetheoretical yield除了%的收益率。使用化学计量的因素,以产生所需的值进行详细说明。

实施例问题

Upon reaction of 1.274 grams of copper sulfate with excess zinc metal, 0.392 grams of copper metal was obtained according to the following equation: CuSO4(aq)+Zn(s)⟶Cu(s)+ZnSO4(AQ)。什么是百分比的收益呢?

Step-by-Step Solution

要查找%的收益率,只是质量值附加到相应的化学物质,并要求化学计量“1.274克硫酸铜+锌 - >0.392克的Cu +硫酸锌的化学计量”。

“1.274克硫酸铜+锌 - >0.392克的Cu +硫酸锌的化学计量” 0.392 g Cu + ZnSO4 stoichiometry"" width="620" height="1708" class="alignnone size-full wp-image-64344">

Challenge Problems

Test your chemical reaction problem-solving skills by using the Wolfram|Alpha tools described to solve these word problems. Answers will be provided in the next blog post in this series.

  1. 计算对乙酰氨基酚的分子量。是最大的原子数也具有最大质量百分比元素的元素?
  2. 什么是限制的反应物和理论产率时24.8克白磷和氧的摩尔数0.200反应形成10.0克五氧化二磷?

And More Chemistry to Come

无论您是为即将到来的期末考试,令人费解了功课或只是为了寻找一个进修学习,化学反应是由钨涉及到许多化学课题之一| Alpha的知识库。manbet万博app下周我们将涵盖一步一步的解决方案万博体育app怎么样chemical solutions, followed by结构和键合, 然后量子化学。如果您有其他的一步一步的建议内容(在化学或其他学科),请告诉我们!阿尔法查询页面|您可以在下面留言或任何钨底部的发送反馈与我们联系。manbet万博app
