Chemical Reaction | Overview & Examples from Chapter 8 / Lesson 1 77K This lesson will cover what happens when a chemical reaction occurs, the types of chemical reactions, and how to know if a chemical reaction occurs. Related to this QuestionWhat...
How does a precipitate form in a chemical reaction? What must happen for a chemical reaction to occur? What does it mean to test for precipitation in chemistry? If there is no color change and no precipitation, can a reaction still be a double replacement reaction?
In a chemical reaction, if the pressure is increased, what will happen to the reaction rate? A. Decrease B. Remain unchanged C. Increase D. Depend on the reaction 相关知识点: 试题来源: 解析 C。解析:对于有气体参与的反应,增加压力通常会增加反应速率,因为压力增加会使气体分子间距离减小,碰撞...
What is the mass of aluminum that can be produced by the reaction of 60.0 g of aluminum oxide with enough amount of carbon according to the following chemical reaction? Al_2O_3 + 3 C \rightarrow 2 Al What makes a neutralization reaction an exothermic process?
This reaction is the complete opposite from helium, a less dense gas with a lower molecular weight than normal air (which is why it makes balloons float). In that case, the sound waves in your larynx move through helium faster than through regular air. The accelerated movement amplifies the...

A crisis can end the tenure of an otherwise great CEO. Or it can be harnessed to propel the company to greater heights. Those who achieve more positive outcomes prepare for crises well before they happen. Future-proofing also means building the strength of your company’s talent bench, includ...
It’s a good choice for cuts and scrapes, particularly those exposed to dirt or water. The antibiotic properties of Neosporin help prevent the wound from turning into an infection, which can happen if you don’t clean your wound correctly after it’s happened. You can find Neosporin at ...
Yes, you are in some sense a giant walking virus… (Humanity has been compared to a cancer on the earth, so a virus may actually be an improvement) – but that’s not all. In his talk at TED2012, researcher and jungle genome operative Nathan Wolfe makes the point that until 1898, ...
of the body. In this article I’ll talk about why that is dangerous, especially if you have autoimmunity, chemical sensitivities, or symptoms of compromised brain function. Chelation often makes people much worse, and it is not due to a “detox reaction” as many practitioners will tell you...
