metallic properties that are caused by atoms rolling over each other in
metallic bonds are malleability and ductility. The atoms that are being rolled
over are delocalized electrons in the sea of electrons in the metallic bond
enable them to roll over when stress is applied.

Explanation:
if you are heating up glass i believe not, unless you want to break the glass. Making glass go from high to low or low to high tempuatures quickly will cause it to break. How ever metal will be stronger as long as you dont bend it.
Answer:
V = 1.84 × 10³ L
Explanation:
You need to use the Ideal Gas Law and solve for volume.
PV = nRT
V = nRT/P
First, you need to convert the pressure to atm.
1 atm = 760 mm Hg
948/760 = 1.247 atm
Next, convert grams of xenon to moles. The molar mass is 131.293 g/mol.
128/131.293 = 0.975 mol
You now have all of the values needed.
P = 1.247 atm
n = 0.975 mol
R = 8.314 J/mol*K
T = 283 K
Plug the values in and solve.
V = nRT/P
V = (0.975 × 8.314 × 283)/1.247
V = 1.84 × 10³ L
The volume of the sample will be 1.84 × 10³ L.
Between between benzene and ethanol , Benzene is the most soluble in hexane. reason been benzene can form a hydrogen bond with hexane, also benzene can form london forces with hexane molecule. In addition benzene can form dipole-dipole interaction with hexane molecules
Answer:
47.5 mm are equal to 4.75 × 10⁻² m.
Explanation:
Meter and millimeter both are units of length. Millimeter is smaller unit while meter is larger unit. The one meter consist of thousand millimeter or we can say that one thousand millimeters are equal to one meter. In order to convert the meter value into millimeter we have to multiply the values with thousand.
we know that one meter is equal to 1000 millimeter.
1 m = 1000 mm
4.75 × 10⁻² × 1000 = 47.5 mm
47.5 mm are equal to 4.75 × 10⁻² m.
