To test this, you'd need to see if a reaction is still taking place, If the enzyme is completely depleted, then the reaction could no longer occur.
The answer is <span>B) the resulting compound cannot be dissolved in water. Ionic compounds are, in fact, very soluble in water. They are known to dissociate in aqueous solutions, producing ions or charged atoms. This makes aqueous solutions of ionic compounds good conductors of electricity. As solids, ionic compounds form salt crystals. They have high melting and boiling points due to the strong ionic bond that holds them.</span>
Answer:11.35 g/cm 3
Explanation:
Length
= 2.0 dm = 20 cm
Breadth
= 8.0 cm
Height
= 35 mm = 3.5 cm
Volume of block
V = ℓ ⋅ b ⋅ h = 20 cm × 8.0 cm × 3.5 cm = 560 cm
3
Density of lead is
Density
=
Mass
Volume
=
6356 g
560 cm
3
=
11.35 g/cm
3
