Kinetic energy due to the movement
<span>Displaced volume:
final volume - initial volume :
38.55 mL - 15.75 mL = 22.8 mL
D = m / V
D = 32.138 / 22.8
D = 1.409 g/mL
hope this helps!

Answer:
all you need if yo look up and say do plants grow without soil but yes they can grow without soil but they cannot grow without the necessities that soil provides.
Answer: 104 KJ mol
Each NH3 has 3 N-H bonds
Explanation:
Enthalpy change(DHo)= sum t enthalpy of products - sum of enthalpy of Reactants
DHo= 2x3 dHo (N-H) - {dHo(N2)+3dHo(H-H)}
= 6(391)-(945+3(432))
=2346-(945+1296)
=2346-2241
DHo= 105 KJ/mole
Answer:
C4H8O4
Explanation:
Let (CH20)x
C=1*12.01=12.01 (12.01, 1.01, 16.00 Avg mass of elements)
H=2*1.01=2.01
O=1*16.00=16.00
12.01 + 2.01 + 16.00 = 30.03
120.12/30,03=4
==> (CH2O)4 = C4H8O4
