Answer:
The particles of matter are in constant motion.
Explanation:
Let us consider each statement:
1) Matter consists of only large molecules: No it is not necessary that matter consists of only large molecules, it depends upon the nature of matter.
2) Matter is made up of only charged particles: no the matter may have any kind of particles charged or uncharged.
3) The particles of matter are in constant motion: Yes according to kinetic theory the matter particles are in constant motion.
4)The particles of matter have zero kinetic energy: it is not possible.
Answer:
400°C
Explanation:
22,000 cal / (0.11 cal/g°C x 500 g) = 400°C
Density is ratio of mass and volume.
therefore Density is equal to mass/ volume
but mass =3.60gand volume =1.8cm3
therefore density is equal to 3.60/1.8
density = 2.0gcm3
Answer:
212.996 or 213 approx.
hope it helps.
Molar mass of Al - 27
Molar mass of N - 14
Molar mass of O - 16
so, the molar mass of (No3)3 will be (14+16×3)3 which is equals to 186.
so, Molar mass of Al(No3)3 will be 186+27 = 213.
feet equal twelve inches, 2 pie r = 12 inches if you want the radius divide twelve over 2 pie, you could also keep the one and you will have the radius in feet
