Explanation:
Explanation:
If the density of the object is more than that of water, it will sink. Otherwise it will float. The density of water is 1 g/mL.
Substance 1,
Mass, m = 450 g, Volume, V = 90 mL
Density = mass/volume
So,
![d_1=\dfrac{450}{90}\\\\=5\ g/mL](https://tex.z-dn.net/?f=d_1%3D%5Cdfrac%7B450%7D%7B90%7D%5C%5C%5C%5C%3D5%5C%20g%2FmL)
It will sink.
Substance 2,
Mass, m = 35 g, Volume, V = 70 mL
Density = mass/volume
So,
![d_2=\dfrac{35}{70}\\\\=0.5\ g/mL](https://tex.z-dn.net/?f=d_2%3D%5Cdfrac%7B35%7D%7B70%7D%5C%5C%5C%5C%3D0.5%5C%20g%2FmL)
It will float.
Substance 3,
Mass, m = 24 g, Volume, V = 12 mL
Density = mass/volume
So,
![d_3=\dfrac{24}{12}\\\\=2\ g/mL](https://tex.z-dn.net/?f=d_3%3D%5Cdfrac%7B24%7D%7B12%7D%5C%5C%5C%5C%3D2%5C%20g%2FmL)
It will sink.
Answer:
Explanation:
Al (s) + CuSO4 (aq) → Cu (s) + Al2(SO4)3 (aq)
2Al (s) + 3CuSO4 (aq) → 3Cu (s) + Al2(SO4)3 (aq).
is the balance chemical equation
