Answer:

float

Explanation:

density= mass/ volume (kg/m^3)

1.59 kg/0.197 m^3

=8.07 kg/m^3

density of H2O= 1000 kg/m3

since density(block)<density(H2O), the block will float

(can also be done in g/cm^3)

1590 g/ (1.97*10^5 cm3)= 0.00807 g/cm^3 < 1 g/cm^3 (h2O)

The solubility of Z is 60 g/ 100 g water at 20 °C. How many grams of solution are produced when a saturated solution is prepared
V125BC [204]

Answer:

Saturated solution = 180 gram

Explanation:

Given:

Solubility of Z = 60 g / 100 g water

Given temperature =  20°C

Amount of water = 300 grams

Find:

Saturated solution

Computation:

Saturated solution = [Solubility of Z] × Amount of water

Saturated solution = [60 g / 100 g] × 300 grams

Saturated solution = [0.6] × 300 grams

Saturated solution = 180 gram

How do the metals in group 1 compare with the transition metals?
Nimfa-mama [501]

Answer:

Group 1 metals and transition metals are different from each other, mainly based on the colour of the chemical compounds that they form. The key difference between group 1 metals and transition metals is that the group 1 metals form colourless compounds, whereas the transition metals form colourful compounds.
