\huge\bold\red{Answer:-}

It’s the same as when magnesium reacts with liquid water, only faster:

Mg + 2H₂O → MgO + H₂.

The difference is that in water, the reaction has a second step, converting MgO to Mg(OH)₂.

Why might a geologist ask an analytical chemist to help identify the minerals in a rock.
Galina-37 [17]

 A geologist will ask an analytical chemist to help identify the minerals in a rock because an analytical chemist studies the composition of matter and, therefore, can identify the minerals.

The analytical chemist does this by determining the crystal structure as a matter of routine using X-ray and electron diffraction techniques.

What mass of aluminum is produced by the decomposition of 5.0 kg al2o3?
Nina [5.8K]
The  mass for  of aluminum that is produced  by  the decomposition  of  5.0 Kg Al2O3 is 2647 g or 2.647  Kg

          calculation
  Write  the equation for decomposition  of Al2O3

Al2O3 = 2Al  + 3 O2

find the  moles  of  Al2O3 =  mass/molar mass

convert  5 Kg  to g   = 5 x1000 = 5000 grams
molar mass of  Al2O3 =  27 x2 + 16 x3  = 102 g/mol

 moles =5000 g/  102 g/mol = 49.0196 moles

by use  of mole ratio between Al2O3 to  Al  which is 1:2  the moles of Al = 49.0196 x2 =98.0392  moles


mass of  Al = moles x molar  mass

= 98.0392 moles x  27g/mol = 2647  grams  or 2647/1000 = 2.647 Kg

Suggest a method for measuring the size of the colony.
Evgen [1.6K]

Answer:

Counting the number of colonies that arise on a pour plate can calculate the concentration by multiplying the count by the volume spread on the pour plate. Direct counting methods are easy to perform and do not require highly specialized equipment, but are often slower than other methods

Explanation:

What type of substance reacts with limestone (CaCO3) and produces carbon dioxide gas?
Anestetic [448]
Acids react with calcium carbonate and more specifically carbonate to form carbon dioxide. An acid will give protons to the carbonate anion to produce carbonic acid which then decomposes into carbon dioxide and water. I hope this helps. Let me know if anything is unclear.
