Answer:
Large change in temperature makes heat flow fast.
Explanation:
NaBr + CaF2 → NaF + CaBr2 What coefficients are needed to balance the chemical equation? A) 1,1,1,1 B) 1,2,1,2 C) 1,2,2,1 D) 2,1

D.
2NaBr + CaF2 --> 2NaF + CaBr2 gives you:
2Na 2Na
2Br 2F
1Ca 1Ca
2F 2Br
This is balanced.
Answer:
it would be an alloy
Explanation:
It is a type of substance that is made by the melting of two or more elements together.
General principle of solubility is 'like dissolves like'

is an ionic compound, wherein the constituent ions (

and

) are held by electrostatic forces of interaction.
Such ionic compounds are soluble in polar solvents.
Among the solvent mentioned in question, water (

) has maximum polarity. Hence,

is most likely to dissolve in
Density = 0.601 g/mL
Volume = 7.25 mL
D = m / V
0.601 = m / 7.25
m = 0.601 x 7.25 => 4.35725 g
hope this helps!
