Yes it is possible
Explanation:
Galena and gold can become encrusted together. They can form together in the same geologic setting.
- Gold usually occurs freely in nature uncombined with other atoms.
- Galena is the largest ore of lead.
- Both minerals can become twinned under appropriate geologic conditions.
- They are usually seen in pegmatitic intrusions in a rock body as product of late stage melt crystallization.

I change the coefficient 2 to 2 times 2 that will give me 4 so at this point on each side of the equation I have the same number for each type of atom that means this equation is balanced.
Without units, the results of your measurement would be unclear and it would be hard to know what each seperate measurement is telling you.
Answer:49.3
Explanation:4.1j/g c * 25g * (t2-45c)=455j
T2-45c = 455j/4.1j/g c * 25g
455/104.6
45+4.3= 49.3 celsius
Answer:
3.39 * 10^-41 m
Explanation:
Given that:
speed of airplane = 880 km/hr
Mass of airplane = 80000 kg
Debroglie wavelength (λ) = h / mv
h = planck's constant = 6.626 * 10^-34
; mass = 80000kg
Velocity = 880km/hr to convert to m/s
Velocity = (880 * 1000m) / 3600 =244.44 m / s
λ = (6.626 * 10^-34) /(80000*244.44)
λ = (6.626 * 10^-34) / 19555200
λ = 3.3889 *10^-41
λ = 3.39 * 10^-41 m
