Answer:
An x-ray detector, because x-rays are produced due to high energy collision of electrons
Explanation:
In order to check if metals are present in a given rock sample, different types of equipment are used. Example of such equipment is an x-ray detector. These x-rays are usually created when the direction of fast-moving electrons are changed as a result of their collision with a metal in a given rock sample. Thus, the best type of equipment that the metallurgical student could use to check if metals are present in a given rock sample is the x-ray detector.
Set up a proportion os V1/n1 = V2/n2. V is the volume, n is the amount in MOLES, not grams. Convert the CO_2 to moles, then solve and find that the amount of N_2 should be the same amount of moles. Then use the molar mass of N_2 (28.02 grams/mole) to convert that amount of moles into grams. That's your answer.

Answer:
2/6
Explanation:
In a balanced chemical equation as:
aA + bB → cC + dD
Where coefficients of reaction relates the number of moles of substances that are involved in the reaction. In the reaction:
Mg₃N₂(s) + 6H₂O(l) → 3Mg(OH)₂(s) + 2NH₃(g)
Per mole of Mg₃N₂(s) and per 6 moles of H₂O you will produce 3 moles of Mg(OH)₂(s) and 2 moles of NH₃(g).
To convert moles of H₂O to moles of NH₃ you can use:
X moles of H₂O ₓ (2 moles NH₃ / 6 moles of H₂O)
That means conversion factor to convert the number of moles of water to number of moles of ammonia is <em>2/6</em>.
<em>-It is important to say that obtention of conversion factor requires, in the first, the balanced chemical equation-</em>
