Because i think melting is kinda the biproduct of evaporation.
Answer:
18 electrons
Explanation:
Note: The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it.
Answer:
Box is made up of <em>copper</em>, because density is <em>8.96 g/cm³.</em>
Explanation:
Given data:
Volume of box = 17.63 cm³
Mass of box = 158 g
Which metal box is this = ?
Solution:
First we will calculate the density of box then we will compare it with the density value of given metals.
d = m/v
d = 158 g/ 17.63 cm³
d = 8.96 g/cm³
The calculated density is similar to the given density value of copper thus box is made up of copper.
.5 mol of A will be left over since 1.5 mol of A will be used for every 3 mol of B due to the 2:1 ratio established by the formula.
Kg = 3.20 x 10^4 troyounces x 0.0311kg/1 troy ounce = 995.2 kg
