Answer:
Copper(II) nitrate and potassium hydroxide are soluble ionic compounds, which implies that they dissociate completely when dissolved in water to produce ions. ... You can thus say that the balanced chemical equation that describes this double ... Cu(NO3)2(aq)+2KOH(aq)→Cu(OH)2(s)⏐⏐↓+2KNO3(aq).
Answer:
Likely
(indium.)
Explanation:
Number of atoms:
.
Dividing,
, the number of atoms by the Avogadro constant,
, would give the number of moles of atoms in this sample:
.
The mass of that many atom is
. Estimate the average mass of one mole of atoms in this sample:
.
The average mass of one mole of atoms of an element (
in this example) is numerically equal to the average atomic mass of that element. Refer to a modern periodic table and look for the element with average atomic mass
. Indium,
, is the closest match.
It remains constant because it is an element. Just like Chernobyl, there is still active radiation. Radiation is something that stays in the air for a verrrry long time. <span>Radioactivity kill cells, so lets say you have your phone on but its in your pocket.the radiation from the phone is killing your cells.</span>
