Al2(SO4)3 + 3Ca(OH)2 -> 2Al(OH)3 + 3Ca(SO)4
Answer: 3 Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same
Explanation:
Physical change mainly physical properties of a substance while the chemical changes remain unchanged. Once there is a change to the chemistry of the substance, this would be classified as a chemical change.
Answer:
Mass of 205 mL of the liquid is 164 g
Explanation:
We know, ![density=\frac{mass}{volume}](https://tex.z-dn.net/?f=density%3D%5Cfrac%7Bmass%7D%7Bvolume%7D)
Here density of liquid is 0.798 g/mL and volume of liquid is 205 mL
So, mass of liquid = ![density\times volume](https://tex.z-dn.net/?f=density%5Ctimes%20volume)
= ![(0.798 g/mL)\times (205 mL)](https://tex.z-dn.net/?f=%280.798%20g%2FmL%29%5Ctimes%20%28205%20mL%29)
= 164 g
hence mass of 205 mL of the liquid is 164 g.
