Answer:
Noble Gases
Explanation:
Noble gases are very unreactive because they already have a full valence shell and therefore, do not need to bond.
Heating a substance will make the molecules move faster. It creates thermal energy
Answer:
Q= 0.21472 C
Explanation:
current is the rate of flow of charge through a wire or a circuit.
I = Q/t
Where I is current
Q is charge
t is time
Q=It
from the question, I=0.52 A , t=411 milliseconds
Q = 0.52 *411*
Q= 0.21472 C
Change in size because that just means that more is added rather than anything reacting
In Chemistry:
A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Ores are a mixture of minerals: processed to produce an industrial mineral or chemically treated to produce one or more metals. The steel, aluminum, chromium, zinc, mercury, manganese, tungsten, and some copper ores are typically processed for just one element.
