Answer:
The new volume of the gas is decreased, to 0.329 L
Explanation:
Step 1: Data given
Volume of oxygen = 500 mL = 0.500 L
Pressure = 1.3 atm
Temperature = 25.0 °C
Temperature increases to 29.0 °C
New pressure = 2.0 atm
Step 2: Calculate new volume
p1*V1/T1 = p2*V2/T2
⇒with p1 = the initial pressure = 1.3 atm
⇒with V1 = the initial volume = 0.500L
⇒with T1 = the initial temperature = 25 °C = 298 K
⇒with p2 = the new pressure = 2.0 atm
⇒with V2 = the new volume = TO BE DETERMINED
⇒with T2 = the new temperature = 29 °C = 302 K
(1.3 * 0.500)/298 = (2.0 * V2) /302
0.0021812 = 2.0V2 / 302
V2 = 0.329 L = 329 mL
The new volume of the gas is decreased, to 0.329 L
I'm pretty sure there are 5 neutrons and 5 protons and all together they make an electron
Answer:
3. Granite and Gneiss.
Gneiss is a coarse to medium grained banded metamorphic rock formed from igneous or sedimentary rocks during regional metamorphism. Banded gneisses called migmatites are composed of alternating light colored layers of granite or quartz feldspar and dark layers rich in biotite.
Granite is a purely natural stone that comes directly from stone quarries and is then cut into thin slabs, polished, and fabricated into countertops. So-called quartz countertops are engineered stone products that may contain a large percentage of natural quartz but may also include other minerals.
