Explanation:
First, get both values into the same units
To covert from Kelvin to degrees C, subtract 273.15
1210 - 273.15 =936.85
Melting point of germanium=936.85 degrees C
Melting point of gold= 1064 degrees C
Therefore germanium would melt first because it has the lower melting point.
Answer:
3 Pb(NO3)2 + Al2(SO4)3 = 2 Al(NO3)3 + 3 PbSO4
Explanation:
I think your equation is incorrect? This is balanced and the sum of coefficients is 9.
Answer:
![Kc=\frac{[HI]^2}{[I_2][H_2]}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BI_2%5D%5BH_2%5D%7D)
Explanation:
Hello there!
In this case, for these equilibrium problems it is firstly necessary to know the balanced reaction at equilibrium:
H2((g) + I2(g) ⇋ 2HI(g)
Next, by means of the law of mass action, it turns out possible for us to write the required and correct expression for the equilibrium constant by considering the concentrations and the coefficients in the aforementioned reaction:

Answer: A woman kicks a soccer ball and scores a goal.
Explanation:
Potential energy: it is the energy possessed by the body due to its position.
Kinetic energy: it is the energy possessed by the the body due to its motion.
When a woman kick's a soccer ball she transferred her potential energy to soccer ball.Due to this action soccer ball comes into motion which means potential energy imparted to the ball starts getting converted into kinetic energy.
- gas forms: bubbles or odor
- precipitate(solid)forms: becomes cloudy or see sediment settle to the bottom
- release / absorption of energy: change in temperature or gives off light
- color change
