Answer:
n = 3.0 moles
V = 60.0 L
T = 400 K
From PV = nRT, you can find P
P = nRT/V = (3.0 mol)(0.0821 L-atm/K-mol)(400 K)/60.0L
P = 1.642 atm = 1.6 atm (to 2 significant figures)
Explanation:
Answer: two elements and three atoms
Explanation:
An element is the simplest substance and hence cannot be broken down using chemical reactions.
Magnesium chloride 
is an ionic compound formed by the transfer of electrons from element magnesium (Mg) to element chlorine (Cl) where Magmesium forms a cation 
by losing two electrons and chlorine forms an anion 
by gaining electron.
There are 3 atoms in Magnesium chloride which include one atom of magnesium (Mg) and two atoms of chlorine (Cl).
K is in the first group can form ion K⁺,
N is in third group can form negative ion (8-5=3) N³⁻
The hydroponic garden is different than a normal garden because the plants are required to find more components in the soil. One more difference among hydroponic gardening or ordinary gardening is that hydroponics could be complex. fertilizer for hydroponic growing are usually in more immaculate structure than are regular fertilizer.
