What does the reaction rate say about the reaction?
It indicates how fast reactants become products.
Is volume conserved in a chemical change?
No. It may be the same before and after, but it certainly doesn't have to be (and often isn't), so it would be wrong to say it's "conserved". Some examples: To a first approximation, in the reaction H2 + Cl2 -> 2HCl the products have the same volume as the reactants. However, in the reaction N2O4 -> 2NO2, the reactant volume is half the volume of the products, assuming that the pressure is constant.
What does is mean when a system has reached equilibrium?
if there is no motion of a lever around a fulcrum, then how do the torques compare? the torques must be equal. this does not necessarily imply that the forces or the lever arms involved are equal. when this situation occurs we say the lever system is in equilibrium.
What does it mean when chemists say that a reactant is reduced?
When a reactant is reduced, it gains electrons. Thus, metal cations can be reduced to neutral metal atoms.
What is the stress experienced by a chemist?
Chemistry is very complex; some intellectual stress results. Chemists may also have occasion to handle very toxic and/or highly explosive chemicals, which can also be stressful. Research chemists often have to worry about getting research grants, which is the most stressful aspect of chemistry. But in spite of those sources of stress, I would still say that on the whole, chemistry is not an overly stressful occupation, for those who are qualified to practice it.
What are its reactants and products?
watever i say son
What does it mean to say a reaction proceeds to 10 percent completion?
It means 10% of reactants have been converted into products and 90% are still there as reactants.
What does the reaction rate say about the reaction?
It indicates how fast reactants become products.
If the only reactions of a reaction were Zn and HCl what does the law of conservation of mass say about the products?
the products will contain only Zn,H, and Cl. apex
The only reactants in a reaction were Zn and HCI. What does the law of conservation of matter say about the products?
The product will contain only Zn, H, and CI. -Apex
What are the reactants and products common to all neutralization reaction?
This question depends on your definition of acids and bases. Assuming we are talking about simple neutralization of acids and bases in water as a solvent, then the reactants are hydrogen and hydroxide ions and the product is water.H+(aq) + OH-(aq) --> H2O(l)At an even simpler level we can say acid + base --> salt + water.

What is a solution at equilibrium?
equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants

What would a chemists reaction if you a 15 year old boy asked for condoms say?
surprised and confused
Is a reactant a chemical change?
Yes, reactants participate in a chemical reaction. In fact, without the reactants, there wouldn't even be a chemical reaction, so reactants create the chemical reaction. They do more than just participate.
What Toshiba products does Toshiba coupons cover?
The coupon will list specifically the items the product is good for. The coupons may also restrict where you can purchase the products. For example, the coupon may say "valid only at Wal-Mart"
