Answer:
you can tell diorite is an intrusive igneous rock because it has a coarse-grained texture
THE ANSWER IS B. The reducing of oxidation state (-1 to -2, a change of -1, a REDUCTION) is what makes it a reduction.
B) a geographical map
Explanation:
A geographical map is an example of a model.
A model is an abstraction of the real world. It simply helps us to have a simplified view about a course we are studying.
- A map is model based on several projections and mathematical underlining principles.
- The gives an image of the 3-D world in a 2-D format usually on paper.
- The earth is a spherical body but a map shows two dimensions mostly.
- Also, a map has scale which helps to freely work with them and comprehend them more:.

Answer:
The molarity of the solution is 0.048 M (option B)
Explanation:
<u>Step 1: </u>Data given
Sucralfate has a molar mass of 2087 g/mole
mass = 1g
volume = 10 mL
<u>Step 2: </u> Calculate moles of sucralfate
Number of moles = mass of sucralfate / Molar mass of sucralfate
Number of moles = 1 g / 2087 g/mole = 4.79 * 10^-4 moles
<u>Step 3:</u> Calculate molarity
Molarity = Number of moles / volume
Molarity = (4.79 * 10^-4 moles) / (10 *10^-3 L)
Molarity = 0.0479 M ≈ 0.048 M
The molarity of the solution is 0.048 M (option B)
