Answer:
d = 8 g/mL
Explanation:
Given data:
Mass of metal = 24 g
Volume of eater = 45 mL
Volume of water + metal = 48 mL
Density of iron metal = ?
Solution:
Volume of metal:
Volume of metal = volume of water+ metal - volume of water
Volume of metal = 48 mL - 45 mL
Volume of metal = 3 mL
Density of metal:
d = m/v
d = 24 g/ 3 mL
d = 8 g/mL
Answer:
False
Explanation:
Liquid particles move fast but they move slower than gas particles. Gas particles move faster than liquid particles because it has more kinetic energy than liquid particles.
Explanation:
An ionic solution is when a compound's ions in an aqueous solution have dissociated. As you combine two aqueous solutions, a reaction occurs. This is when you find out whether or not a precipitate is going to form. A precipitate occurs when the ion reaction component in water is insoluble.The formation of a precipitate is an indication that a chemical change has occurred. for example if we mix clear solutions of silver nitrate and sodium chloride, sodium nitrate is formed which is a precipitate.

Answer:
C 2sp³ + 2sp³ O
Explanation:
Carbon has an atomic number equal to <em>6</em>, so its electronic distribution is:
1s²2s²2p²
Oxygen has an atomic number equal to <em>8</em>, so its electronic distribution is:
1s²2s²2p⁴
In dimethyl ether, the bonds between carbon and hydrogen and carbon and oxygen are saturated, so there will be only sigma bonds. The sigma bonds occurs in hybrids orbitals, and pi bonds on normal orbitals. So, the carbons and the oxygen of that compound has hybridization
2sp³, because they need 4 hybrid orbitals.
So the bond C-O occurs between C 2sp³ + 2sp³ O
