They tend to pick at it until it is in small enough pieces to swallow. Then their gizzard (rough muscle) in their stomach acts as internal teeth.
Answer = 23.2146762081 pounds.

13% of 81 = 10.53
10.53 converted to pounds (lbs) = 23.21......pounds
EDTA stands for ethylenediamine tetra - acetic acid. It is a crystalline acid with a strong tendency to form chelates with metal ions.
Answer:
V=25.133 cm^3
(Is 4 the diameter you were given? To get one of those answers, I think you May have put the wrong diameter)
Explanation:
Radius is diameter/2
R=4/2
R=2
Volume of a sphere=4/3πr3
V=4/3π(2)3
V=25.133 cm^3
Answer: D.) 25.9%
Explanation:
Dinitrogen pentoxide chemical formular : N2O5
Calculating the molar mass of N2O5
Atomic mass of nitrogen(N) = 14
Atomic mass of oxygen(O) = 16
Therefore molar mass :
N2O5 = (2 × 14) + (5 × 16) = 28 + 80 = 108g/mol
Percentage amount of elements in N205:
NITROGEN (N) :
(Mass of nitrogen / molar mass of N2O5) × 100%
MASS OF NITROGEN = (N2) = 2 × 14 = 28
PERCENT OF NITROGEN : (28/108) × 100%
0.259259 × 100%
= 25.925%
= 25.9%
