Answer:
The speed at which the reactants change to products over a given time.
Explanation:
A chemical's <u>reaction rate</u><u> is the change in the concentration of a reactant or a product with time (in moles per second)</u>.
Remember that during a chemical reaction, reactants are converted to products. Or what is the same, products are formed at the expense of reactants. This can be represented:
reactants → products
Therefore,<u> the progress of a reaction can be followed measuring the decrease in concentration of the reactants or the increase in concentration of the products.</u>
According to the temperature and other parameters, the reaction rate can increase or decrease.
Covalent bonds are formed when two non metal atoms share an electron. The atoms either give up or gain an electron, due to the outer shell being unstable.
Answer:
Explanation:
Economics our environment are connected in an ongoing cycle we have created. Economics have a special influence on the environment because of the way we have set up our social system. There are many good affects of this cycle, such as people reserving land for endangered species. However, there are also bad affects, such as people monopolizing land just for themselves.
The concentration of Na+ is greater inside the cell, and the concentration of K+ is greater outside the cell.
The concentrations of Na+ and K+ are both greater outside the cell.
The concentrations of Na+ and K+ are both greater inside the cell.
The concentration of Na+ is greater outside the cell, and the concentration of K+ is greater inside the cell.
