Which of the following solutions will have the lowest freezing point?

Physics
1 answer:
gregori [183]3 years ago
7 0
 C. 1.0 mol/kg sodium phosphide (Na3P)<span> 

This is because it will produce 4 ions, and thus has the highest molalitiy. (more particles in solution lowers the freezing point) 

</span><span>remember if you ever need anything and you dont want to waste points you can just post it on my pfp or message me the question</span>

An ice cube floats in a glass of water. will cold flow from ice into the water
Ber [7]
It'll certainly seem like it, because the water will get cold. But cold is not a thing. Heat is. What actually happens is that heat from the water flow into the ice (and melts it).

Based upon the information you have learned throughout this module on blood spatter analysis, do you feel that analyzing blood s
kompoz [17]

Answer:

I do not think that it is the most reliable way to gain information since it is very hard to do and can be easily messed up. No, I don't think you can charge someone on only evidence from blood spatter, but if there was additional evidence I think that this would definitely help with the case but not on its own, since it doesn’t give you physical evidence about the suspect.

What conclusions can be drawn about the existence of nitrogen-14 and nitrogen-15? A) They are isotopes of nitrogen and they cont
AleksandrR [38]
<span>Answer: A) They are isotopes of nitrogen and they contain the same number of protons and electrons but each contains a different number of neutrons - 7 and 8 respectively.

Isotopes are atoms of a chemical element whose nucleus has the same atomic number, Z, but different atomic mass, A. The atomic number corresponds to the number of protons in the atom, therefore the isotopes of an element contain the same number of protons and electrons (atoms have to be neutral particles). The difference in atomic masses arises from the difference in the number of neutrons in the atomic nucleus.

A sand core used to form the internal surfaces of a steel casting experiences a buoyancy force of 225 n. the volume of the mold
pashok25 [27]

Newton’s second law gives us the relationship of force F, mass m and acceleration a. The formula is given as:

<span>F = m a                  --> 1</span>

However we also know that the relationship of mass m, density ρ, and volume V is:

<span>m = V ρ                 --> 2</span>

Therefore substituting equation 2 to equation 1:

F = ρ V a = ρ V g

where a is acceleration due to gravity, ρ is density of water and V is the volume of the casting, therefore:

F = (1x10^-3 kg/cm^3) (4840 cm^3) (9.8 m/s^2)

F = 47.432 kg m/s^2

F = 47.432 N

 

Going back to equation 1:

47.432 N = m (9.8 m/s^2)

m = 4.84 kg

 

<span>Hence the weight of the final casting is 4.84 kg</span>
