x 0,025
HCl+KOH--> KCl + H2O
1 1
c=1M
V=25ml=0,025l ( you need the volume to be in l)
c = n/V
n=c*V
n=1*0,025=0,025 m KOH
x=0,025m
c=1 M
V=n/c
V=0,025/1=0,025l=25ml HCl
Answer:
I think Orange juice is a homogeneous mixture
Nontoxic , colorless , and nonmetallic
Mg3N2 + 6H2O => 3Mg(OH)2 + 2NH3
Explanation:
Al2O3
16=molar mass of one oxygen atom
Number of moles: mass/molar mass
Mol of O3: 19÷(16*3) = 0.40 g/mol
mole ratio
0.40: 3 (oxygen)
0.27: 2 (aluminum)
Mass = molar mass*mole
0.27*(27*3)= 21.87g
