Answer:
D) The water will freeze into cubes again.
Explanation:
When the ice cubes is left on a counter, it will melt as the forces that make its molecules stick together is broken.
If that tray is put back in the freezer again, the water will freeze into cubes again.
When water freezes, the molecules slow down and settle into its place, arranging in a regular shape that can be appeared as crystals (ice cubes).
Answer:
Their digestive systems produce methane, a powerful
greenhouse gas
Answer:
1.47 mol/L
Explanation:
Molarity is given as,
Molarity = Moles / Vol in L ------- (1)
Moles of CaCl₂,
Moles = Mass / M.Mass
Moles = 535 g / 110.98 g/mol
Moles = 4.82 mol
Now, putting values in eq. 1.
Molarity = 4.82 mol / 3.28 L
Molarity = 1.47 mol/L

The most soluble of the compounds given above is [NH4]3PO4. [NH4]3PO4 is a salt of ammonium and phosphate; it is a white crystal at room temprature. It is an highly unstable compound and thus easily decompose when mixed with water.
