It is protons that are involved for chemical bonding
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.
1cm = 0.01m
1cm x 172 = 0.01 x 172
172cm = 1.72m
The formula is NaCl. this indicates that it has one sodium atom and one chlorine atom. it is an ionic compound, because it contains one metal and one nonmetal atom.
Answer:
9.91 mL
Explanation:
Using the combined gas law equation as follows;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (torr)
P2 = final pressure (torr)
V1 = initial volume (mL)
V2 = final volume (mL)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question;
V1 = 15.0mL
V2 = ?
P1 = 760 torr
P2 = 1252 torr
T1 = 10°C = 10 + 273 = 283K
T2 = 35°C = 35 + 273 = 308K
Using P1V1/T1 = P2V2/T2
760 × 15/283 = 1252 × V2/308
11400/283 = 1252V2/308
Cross multiply
11400 × 308 = 283 × 1252V2
3511200 = 354316V2
V2 = 3511200 ÷ 354316
V2 = 9.91 mL
