Answer:
Yes, the 150-mL Erlenmeyer will be large enough to contain the acid.
Explanation:
As an instructor is preparing for an experiment, he requires 225 g phosphoric acid. Considering that the density of the phosphoric acid is 1.83 g/mL, we can find the volume occupied by the acid using the following expression.
density = mass / volume
volume = mass / density
volume = 225 g / (1.83 g/mL)
volume = 123 mL
The phosphoric acid occupies 123 mL so the 150-mL Erlenmeyer will be large enough to contain it.
As you move from left to right on the periodic table, metallic character decreases.
Answer:
Color, odor, density, melting temperature, boiling temperature, and solubility are examples of physical properties. Physical properties can be used to identify a pure substance.

Answer: Bosch process
Explanation:
Bosch process is an industrial process for the manufacture of H2. This proces uses cheap raw materials( water and coke) to generate water gas which is mixed with water in the presence of a catalyst(iron(II) oxide or chromium(iii) oxide) to generate H2
The word problem format to the task given above is: When magnesium reacts with steam, it produces magnesium hydroxide and liberate hydrogen gas.
<h3>How magnesium hydroxide is formed?</h3>
It happens that magnesium is an alkali earth metal and react with water in the gaseous state to librate hydrogen gas, when this reaction occurs, it results in the formation of magnesium hydroxide.
The chemical equation between magnesium and water is given below:
Mg + 2H₂O -----> Mg (OH)₂ + H₂
So therefore, we can accurately deduced that magnesium hydroxide is produced when magnesium is disolved in water.
