Answer:
The professionals that most likely use X-ray technology are a dentist and an airport-security scanner.
A dentist would scan your teeth using X-ray technology to see whether there are any cavities within the teeth themselves which he couldn't otherwise see with the naked eye. An airport-security scanner would use this technology to scan your luggage to check whether there are any weapons and other illegal products.

Methanoic acid
Lactic acid
Answer:
The Standard Model of particle physics is the theory describing three of the four known fundamental forces (the electromagnetic, weak, and strong interactions, and not including the gravitational force) in the universe, as well as classifying all known elementary particles. It was developed in stages throughout the latter half of the 20th century, through the work of many scientists around the world, with the current formulation being finalized in the mid-1970s upon experimental confirmation of the existence of quarks.

<u>Answer:</u> The standard cell potential of the cell is -0.71 V
<u>Explanation:</u>
The half reactions follows:
<u>Oxidation half reaction:</u> 
( × 3)
<u>Reduction half reaction:</u> 
( × 2)
The balanced cell reaction follows:
To calculate the 
of the reaction, we use the equation:
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
Putting values in above equation, we get:
Hence, the standard cell potential of the cell is -0.71 V
