Answer:
A. Offspring are genetically identical to the parent.
That's the answer. I hope it helps!
Answer:
n = 0.594 mol
Explanation:
Parameters of the question.
Heat = 979J
Initial Temperature (T1) = 10.6 C = 283.6 K (converting to Kelvin by adding 273)
FinalTemperature (T2) = 26.4 C = 299.4 K (converting to Kelvin by adding 273)
ΔT = T2 -T1 = 299.4 - 283.6 = 15.8K
Work done (W) = 221 J
number of moles (n) = ?
Formular to be used;
W=PΔV
From ideal gas equation,
PV = nRT
PΔV = nRΔT
where R = gas constant = 8.314 J / mol·K
Sunstituting in the work done equation,
we have W=nRΔT
Making n subject of formular,
n = [8.314 * 15.8]/221
n = 131.36/221
n = 0.594 mol
NH4+1 ammonium
NO3-1 nitrate
The volume of the liquid in each cylinder are given below
A. 48.9 mL
B. 48.5 mL
C. 11 mL
<h3>Shape of liquid in a cylinder</h3>
A liquid in a cylinder tends to show a curved shape due to adhesion.
Hence, to get an accurate measurement, we must take the reading at the lower meniscus (i.e under the curve shape of the liquid)
<h3>A. How to determine the volume of the cylinder</h3>
From the diagram given, we can see that the lower meniscus (i.e under the curve) is 48.9 mL since 10 lines exist between 48 and 49. Thus, the volume of the liquid is 48.9 mL
<h3>B. How to determine the volume of the cylinder</h3>
From the diagram given, we can see that the lower meniscus (i.e under the curve) is 48.5 mL since 10 lines exist between 48 and 49. Thus, the volume of the liquid is 48.5 mL
<h3>C. How to determine the volume of the cylinder</h3>
From the diagram given, we can see that the lower meniscus (i.e under the curve) is 11 mL since 5 lines exist between 10 and 15. Thus, the volume of the liquid is 11 mL
