the diagram below represents two beakers, each containing an ice cube and clear liquid. in beaker A the ice cube floats, and in
Mama L [17]

Answer:

The density of the liquid in beaker B is less than the that of ice.

Explanation:

Ice will float if its mass is less than the mass of the liquid it displaces.

For example, the density of ice is less than that of water.

A 10 cm³ cube of ice has a mass of about 9 g, while the mass of 10 cm³ of water is 10 g. Thus, 9 g of ice displaces 10 g of water.

The denser water displaces the lighter ice and the ice floats to the top.

If the density of the liquid is <em>less than</em> that of water, say, 8 g/cm³, the ice will displace only 8 g of the liquid. The ice will sink.

Calculate the mass of 0.2 moles of zinc nitrate.
Marina86 [1]

Answer:

mass = 37.8 g

Explanation:

mass = mol × molar mass

mol = 0.2

molar mass = Zn(NO3)2

Zn = 65

N = 14

O = 16

substitute the values into Zn(NO3)2

Zn(NO3)2

= 65+2[ 14+3(16) ]

= 65 + 2(62)

= 65 + 124

= 189 g/mol

mass

= mol × molar mass

= 0.2 mol × 189 g/mol

= 37.8 g

Q4,
Luba_88 [7]

Answer: the answer is option B. Q, R, P

Explanation: the lightest gas (hydrogen) will diffuse first, then followed by carbon dioxide and then followed by air. Air is a mixture of gases. So air is heavier than hydrogen and carbon dioxide.
