Answer:
363C
Explanation:
V = KT and T = V/K
3.5=k(35+273) = 308k
k=3.5/308 =0.011
new T=7.0/0.011=636K = 636-273 =363C
Answer:
Temp decreased
Explanation:
If the container is sealed and the pressure DEcreases, then the temperature DEcreased
PV = n RT n R V are constant if P goes down then so does T
They are stronger than hydrogen bonding forces.
Answer:
Igneous rock
Explanation:
The rock held by Florian is already a metamorphic rock. On further subjection for heat and pressure, the rock will melt to become igneous rocks.
- A banded rock is termed a gneiss
- In such a rock body, areas concentrating dark minerals and light minerals alternates to form the distinct domains.
- This in turn results from a very high grade metamorphic event.
- In retrospect, if this rock body is further heated, a melt or magma form which is the material by which igneous rocks are derived from.
Molar mass of NaOH = 39.997 g/mol
39.997 g ---------- 6.02x10²³ molecules
g --------------- 2.30x10²² molecules
mass = 2.30x 10²² * 39.997 / 6.02x10²³
mass = 9x199^24 / 6.02x10²³
mass = 15.280 g
hope this helps!
