Number of moles ( n ) = ?
Volume ( V ) = 0.25 L
Molarity of solution ( M ) = 2.00 M
n = M x V
n = 2.00 x 0.25
n = 0.5 moles of Ba(NO₃)₂
hope this helps!
Answer:
Dominant traits are always expressed when the connected allele is dominant, even if only one copy exists. Recessive traits are expressed only if both the connected alleles are recessive.
Explanation:
Freckles, cleft chin and dimples are all examples of a dominant trait.

Explanation:
Example #1: How many moles of oxygen will occupy a volume of 2.50 L at STP? Standard ... What is the volume of gas at 2.00 atm and 200.0 K if its original volume was ... P2 = 2.00 atm 2.000tm) 273k. T=273k. 200.0k. Tz= 200.0k. V, = 200.0L ... A gas has a pressure of 0.370 atm at 50.0°C. What is the pressure at standard.
Well, elements are arranged based on a number of factors.
Left to right, elements are arranged based on atomic number. The atomic numbers of the elements are increasing by 1 as you move from left to right.
Top to bottom is based on increasing atomic radius. As you move from top to bottom, each succeeding element in a group gets an additional electron shell, increasing the atomic radius as you move down.
