Answer:
Copper is more reactive and higher in the activity series
Explanation:
Copper is able to replace the silver in a replacement reaction because it is more reactive and higher in the activity series.
Substances or ions that are higher in the activity series are typically more reactive than those ones below them.
In like manner, they are able to replace the lowers ones in a chemical reaction due to their higher reactivity potential.
A less reactive element and a lower one in the activity series cannot displace a higher one in the series.
The volume of the nail since it is an irregular figure you can't measure it like a regular object.
Answer:
the branch of science that deals with the identification of the substances of which matter is composed. the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes.the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes.
Explanation:
B) Catalyst speed up a chemical reaction- this is because they lower the activation energy for a successful collition to take place :)
