Why does using powdered iron make a reaction go faster than using a single piece of iron?
It has a greater surface area than the single piece of iron
Something that helps a chemical reaction go faster is?
It depends on the chemical reating to the source, if it has a major reaction to water it will go faster.
What is the speed at which a reaction progresses?
RATE OF REACTION / REACTION RATE definition? don't go to wikipedia...
What is the fastest a car has gone in reverse?
The Nissan Leaf is the fastest car in reverse. For safety purposes, a stock Nissan Leaf is electronically limited in how fast it can go in reverse. With the limit removed, it has gone about 55 miles/hour in reverse and it set the world record for fastest car in reverse. Most cars are physically limited in how fast they can go in reverse by the transmission, as reverse is roughly equivalent to first gear. The Nissan Leaf has no transmission, instead it has a motor that can put out high torque over a wide range of speeds, making a transmission unnecessary.
In a reaction If the energy of a product is less where does excess the energy go?
It is released as heat and/or light, the reaction is said to be exothermic.
In chemistry what is completion?
going to an end is the removal of a product from a reaction, not permitting the reverse reaction to take place. The formation of a precipitate, gas or un-ionized compounds, such as water, are the requirements to go to completion. Once a reaction has gone to completion, the product can not form the reactants in a reverse reaction (there is no reverse reaction).
Why does copper sulphate solution go from blue to pale green?
Because a displacement reaction has occured
When a precipitation reaction occurs the ions that do not form the precipitate?
A precipitation reaction is usually a double displacement reaction. The ions that do not form the precipitate usually form the solution.
What are the applications of single displacement reaction?
When you displace Kraft Singles (sliced processed cheese) with a natural, healthier substitute, you will grow enormous, firm pectorals and your opposite gender will go crazy and ravage your body in the bedroom, making for a wild night of sexual experiences and cheese.
What are some characteristics of displacement?
Displacement is the change in position. Displacement= where you are now - where you use to be. Ex. you are walking on a path and see a sign that says, "170 m mark". Then you retrace your steps until you end up at a sign that says, "50 m mark". Finally you go forwrd on the path and stop at a sign that says, " 90 m mark". what is your displacement from the 170 m mark? Answer: 90 (where you are) - 170 (where you use to be) = -80 Your displacement is -80 m. Lauren "Physics above all!"
Is grass growing a chemical reaction?
Grass growth is not a chemical reaction but a chemical change because the grass will not go back to its original form after it grows. Like chemical change, a certain object will not go back or reverse it from its original appearance.
What is distance and displacement?
how far you go and displacement is going in a straight line
How do battery chargers work?
Battery Charges reverse the polarity of your battery, so it is like reversing the reaction that occurs when you use the batteries. Your batteries will go out eventually though. because the reaction slowly stops
Why does using powdered iron make a reaction go faster than using a single piece of iron?
It has a greater surface area than the single piece of iron
Does enthalpy of reaction affect the rate of a reaction?
The enthalphy of a reaction does not influence the rate of reaction, it may however influence the rate of the reverse reaction, as we now would have a change in potential energy (for example an exothermic reaction requires more energy to go in the reverse then does an endothermic). This is why you can consider some products thermodynamically favourable - as they are the exothermic product which would require more energy to turn back towards reactants then to stay as products. Overall rate is not seen in the various rate law or rate of reaction equations utilised such as arrhenius temperature dependance or the rate law equation. Rate is indepedant of enthalpy WRT to forward reaction.
If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
What would the reaction of potassium and cold water be like?
You aren't asking anything I don't know how to this. But if you're wondering, potassium does react (explode) to cold water and air, because it's an alkali metal (a element on the very right group or column of the periodic table). All alkali metals really want to lose an electron, making them highly reactive, and the further down the alkali metals you go, the more reactive they are.
