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.
We can change a gas to a liquid by INCREASING the temperature and DECREASING the pressure
Answer:
Here's what I get
Explanation:
Ethylamine has an N atom with a lone pair of electrons.
It can act as a Brønsted-Lowry base and accept a proton from water and become an ethylammonium ion.
The structure of the ion is shown below (there is a C atom at each of the four-way bond intersections).
You're oxidising agent will be reduced. In the molecule MnO4-, Mn has and oxidation number of +9 and in MnO2 it is +4, therefore its oxidation number has reduced, therefore Mn is reduced, therefore it is the oxidant/oxidising agent.
Answer:
Explanation:
The molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 liters.
There are 6.02x10^23 molecules in 1 mole of Argon.
So for 1.51x10^24 molecules of Argon, the volume at STP should be
(1.51x10^24 / (6.02x10^23)) * 22.4
= 56.19 liters
