I will say 3 is wrong because the time of day doesn't matter.But what really matters is 1,2,4 we just need to figure which one is correct.
1.The Wife's blood
Real blood will smell bad and with the time it will turn the color red to a dark-ish color red with brown.To see if it is real you have to see if the blood is a dark brown with red if it's not then it's a fake.
2.The type of Gun
You have to feel if it's a fake it might be plastic or another toy material.The gun has to feel like metal.
So the answer might be 1 or 2
Hope this helps :)
Answer:
mass NH3 = 11.264 g
mass N2 = 9.264 g
Explanation:
balanced reaction:
∴ mass H2 = 2.00 g
∴ molar mass H2 = 2.016 g/mol
∴ molar mass N2 = 28.0134 g/mol
∴ molar mass NH3 = 17.031 g/mol
⇒ mol H2 = (2.00 g)*(mol/2.016 g) = 0.992 mol
⇒ mol NH3 = (0.992 mol H2)*(2 mol NH3/3 mol H2) = 0.6614 mol
⇒ mass NH3 = (0.6614 mol)*(17.031 g/mol) = 11.264 g
⇒ mol N2 = (0.6614 mol NH3)*(mol N2/2 mol NH3) = 0.3307 mol
⇒ mass N2 = (0.3307 mol)*(28.0134 g/mol) = 9.264 g
Answer:
the velocity did change
Explanation:
velocity is the rate of change of its position with respect to a frame of reference.
Answer:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids)
Explanation:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. ... Biological macromolecules are organic, meaning that they contain carbon.
Answer:
As solute concentration increases, vapor pressure decreases.
Step-by-step explanation:
As solute concentration increases, the number of solute particles at the surface of the solution increases, so the number of <em>solvent </em>particles at the surface <em>decreases</em>.
Since there are fewer solvent particles available to evaporate from the surface, the vapour pressure decreases.
C. and D. are <em>wrong</em>. The vapour pressure depends <em>only</em> on the number of particles. It does not depend on the nature of the particles.
