(c) What happens to the speed of the reaction when(i) smaller pieces of zinc are used?goes faster/more hydrogen given off per minute /more gas given off per unit time/les time for same amount of gas(ii) some water is added to the sulfuric acid?goes slower/less hydrogen given offper...

coordination(协调),slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected. Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking ...
Early on, the web is their “third space", but by the late teens, it's replaced in reaction to greater independence. They have to be on Facebook, to know what's going on among friends and family, but they are ambivalent (有矛盾心理的) about it, says Rebecca Eynon, a research fello...

As the normal reaction force increases, what happens to the friction force? Is static friction the same as the centripetal force? What does friction mean in physics? Does sliding friction occur at rest? Are applied force and kinetic friction related?
Ki-Woo becomes more animated at Ki-Tek’s exaggerated reaction. He opens his arms wide and looks around at the living room. KI-WOO Imagine for a second that this is our house. Let’s say we live here. Which room would you like to have? Out of all the beautiful rooms designed by...
Enzymes are a special group of proteins that are responsible for lowering the activation energy necessary to start a chemical reaction. This allows the reaction to proceed much more quickly. Proteins have unique three-dimensional structures that determine their function....
We draw inferences about the workings of visual attention by inspecting the reaction time × set size function (e.g. Duncan & Humphreys, 1989; Treisman & Gelade, 1980; Wolfe, 1994). Notice that the distractors are stimuli created by the investigator to probe how attention works. Therefore, ...
This month, your child’s healthcare provider may offer pointers on introducing solids and tell you about signs of an allergic reaction to watch for as you introduce new foods one at a time. Your child’s provider can also give you personalized advice on which foods to start with, how to...
