The correct answer is: Option (D) 120g
Explanation:
We are given the following:
Mass of sugar = 20 g
Mass of water = 100 g
When sugar is completely dissolved into water, the mass of the solution will get:
mass-of-solution = mass-of-sugar + mass-of-water
mass-of-solution = 20 + 100
mass-of-solution = 120 g (Option D)
Answer:
Label
Explanation:
You need to search if the chemical need a glass or plastic container. Also if the chemical need to be in a clear or dark container that can protect it from light. Also if need to be a certain temperature, for example, if need to be in the fridge or can be at room temperature.
Most important is that you need to label with the name, formula, date, and if you have the number of lot and the expiration date.
(2) a beta particle
(3) a neutron
(4) a positron

Answer : Option D) the electrons in some metals pair up to create a magnetic field.
Explanation : Most of the metalsare magnetic in nature including some exceptions. When the unpaired electrons get aligned with the magnetic field they posses magnetism. Also there are some paired electrons in metals which align themselves according to the magnetic field and create magnetism in them.
The correct answer is C; Metals can become magnetic if they have many spinning electrons that create magnetic fields.
Further Explanation;
As long as there are many spinning electrons anything metal will become magnetic. Ferromagnetic is when there are only some certain types of metals that are attracted to magnetic. If you were to make an electromagnet, you would only need to take an insulated wire and wrap it around the metal that has ferromagnetic properties.
