B. When melted, the chocolate will take the shape of the bowl.
Explanation:
The chocolate chips are heated in the bowl, they will assume the shape of the bowl or container they are placed in.
- They simply undergo a phase change from solids to liquids.
- Solids generally have fixed volume with their rigid shapes.
- Liquids and gases takes up the shape of the container they are placed in.
- Baring no loss of chocolate, the weight will remain the same because weight is function of mass and gravity. Gravity will remain the same, and the amount of matter, the mass will also be the same.

Answer:
If a metal and metal solution react, the more reactive metal will displace the less reactive metal from solution. If the metal in solution you start with is formed from a more reactive metal than the metal to be added, no reaction will occur.
It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.
These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.
Answer:
the mass of the glycerine needed in the given solution is 23.92 g
Explanation:
Given;
molarity of the solution (C₃H₈O₃), C = 2.60 M
Volume of the solution, V = 100 mL = 100 x 10⁻³ L = 0.1 M
The molarity of a solution is given as follows;
The molecular mass of the given solution;
molecular mass = (12 x 3) + (8 x 1) + (16 x 3)
molecular mass = 92 g/mol
The mass of the glycerine needed in the given solution is calculated as follows;
reacting mass = amount of solute (moles) x molecular mass (g/mol)
reacting mass = 0.26 x 92
reacting mass = 23.92 g
Therefore, the mass of the glycerine needed in the given solution is 23.92 g
I believe that the answer would be A. Tree
(Plus I took the assessment like this sooo, Im 100% this is correct)
