Answer:
<u>3.39 grams </u>of AgNo3 are required to make 25 ml of .80M solution
Explanation:
Molarity , M = 0.80
Volume = 25 ml
V = 0.025 L
Here n = number of moles
n = 0.02 mole
Molar mass of AgNO3 = 169.87 g/mol
Mass = 3.397 g
I believe this property is vital since the sticky nature allows the wells to coat easily with the desired antigen by simply adding a small amount of it and allowing it time to incubate. Adhesion is the tendency of dissimilar particles or surfaces to cling to one another ( cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another).
Answer is: 9623.85 kJ of heat is <span>transferred from iron ingot.
</span>m(Fe) = 24.7 kg · 1000 g/kg = 24700 g; mass of iron ingot.
C = 0.4494 J/g°C; t<span>he specific heat of iron
</span>ΔT = 880°C - 13°C; temperature <span>difference.</span>
ΔT = 867°C.
Q = m·C·ΔT.
Q = 24700 g · 0.4494 J/g°C ·867°C.
Q = 9623856.06 J ÷ 1000J/kJ.
Q = 9623.85 kJ.
Answer:
8
Explanation:
there are two ammonium ions with four hydrogen atoms each.
4*2=8
I would say B.HS(aq)+NiSO4(aq)
