Answer:
It will reduce the quantity of metals extracted for use in the manufacturing of electronics
Explanation:
The manufacturing of electronics is a huge market for the metal extraction industry. Many electronics have metal casing, metal circuit boards etc. This implies that a large quantity of metal is required for the production of electronics. This leads to consistent mining activities in order to supply enough quantity of metal to produce more electronics.
However, if electronics are recycled, less metals are extracted for the electronics industry. This saves energy required for mining operations and minimizes the deleterious environmental impact associated with metal mining from the earth. These deleterious consequences include; erosion, sinkholes, loss of biodiversity, contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
Hence, recycling of electronics saves the environment from the degradation caused by consistent mining activities. Reduction of mining activities by recycling ought to be an important goal of the electronics manufacturing industry.

Hello!
In this case, when writing net ionic equations, we first need to identify the complete molecular equation; thus for potassium dichromate reacting with copper (I) bromide, we have:
Thus, since all the species are aqueous except copper (II) dichromate, we can write the complete ionic equation by ionizing the aqueous ones:
Finally, for the net ionic equation, we need to cancel out the spectator ions as they are present at both reactants and products sides, thus, we obtain:

Answer:
A; 0.5
Explanation:
To find the density, you have to do the Mass divided by the Volume; in this case, it's 8.0/4.0.
8/4 = 0.5
