Explanation:
aam= 90%•20amu+10%•22amu/100
aam= 2020/100
aam= 20.2
Answer:
Triclinic crystal forms. Also known as the rhombohedron system, its shape is three dimensional like a cube, but it has been skewed or inclined to one side making it oblique. All crystal faces are parallel to each other. A rhombohedral crystal has six faces, 12 edges, and 8 vertices.
bascially short answer is 6 faces
Answer:
mass of sodium reacted is 184.1 g
Explanation:
mass Na = X = ?
∴ mass NaCl = 468 g
∴ mass Cl = 0.248 g
∴ molar mass NaCl = 58.44 g/mol
∴ atomic mass Cl = 35.453 a.m.u
∴ atomic mass Na = 22.989 a.m.u
⇒ moles Na = (X gNa)*(mol Na/22.989 g) = X/22.989 mol Na
⇒ mass NaCl = (X/22.989 mol Na)*(mol NaCl/mol Na)*(58.44 gNaCl/mol NaCl) = 468 g NaCl
clearing "X":
⇒ ((58.44)(X))/(22.989) = 468 g
⇒ X = 184.1 g = mass Na reacted
Generally speaking mechanical energy is energy which physically moves (the object), while the thermal energy is energy from the movement of atoms.
Basically temperature is a measurement of atomic movement (doesn't move object as a whole).
Hence heat.
