A long thin sample of a substance is easily bent. When the substance is placed in a n electric circuit and the switch is closed, and LED light turns on. What type of bonding holds the particles of the substance together?

A metallic bonding holds the particles of the substance together

Explanation:

The unknown substance is a metal:

passing a magnet thought the

mixture , because iron gets attracted to magnet .

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
