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.
that is called the Gulf Stream

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
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.
