The answer is donate, therefore elements with positive valences usually donate electrons
Communication circuit <em>(D)</em> is becoming more common in residential electrical design and construction.
LAN Ethernet cables, outlets, and even hubs and bridges, are being built into the walls of new homes, along with the usual electrical outlet wiring, to give the owner the networking infrastructure and internet access that everybody needs now ... without stringing a mess of cables on the floor and through doors all over the house.
Answer:
Emissions from power plants that burn fossil fuels increase atmospheric carbon dioxide, which is absorbed by the ocean.
Explanation:
Fossil fuels are burnt in power plants in order to produce energy. These fossil fuels contain carbon. Combustion of these fossil fuels emits oxides of carbon into the atmosphere. The oxides of carbon are carbon II oxide and carbon dioxide.
Carbon dioxide can be absorbed by the ocean to form carbonic acid according to the reaction equation;
CO2(aq) + H2O(l) ------> H2CO3(aq)
This is an anthropogenic activity which increases ocean acidification.
They emit low leavls of carbon dioxide (CO2) and the emissions of green house gases and therefore the contribution of nuclear power plants to global warming is therefore pretty little
Component ' W ' is the standard schematic symbol for a switch.
The short line between the two circles can be shown straight,
like it is now, when the switch is 'closed' and current can flow.
Or, it can also be drawn slightly tilted, so it's not touching one
of the circles. In that case, the switch is 'open', no current can
flow through it, and the whole circuit is shut down.
