Answer is: S<span>AE standard that must be referred to on the label of approved HFC-134a refrigerant recycling machines are </span>J1770 and J2788.
<span>J1770 is to establish the specific minimum equipment requirements for recovery or recycling equipment intended for use with R134a.
</span>J2788 is intended to establish requirements for equipment used to recharge HFC-134a.<span />

The true statement is that the metal on the right oxidizes more easily than the one on the left.
<h3>What is metal oxidization?</h3>
Metal oxidation is known to often occur if an ionic chemical reaction is said to take place on a metal's surface at the presence of oxygen.
Note that Electrons often move from the metal to the oxygen molecules in course of this process and as such The true statement is that the metal on the right oxidizes more easily than the one on the left.

Answer:
0,1 mol of carbon and 0.2 moles of hydrogen were in the original sample.
Explanation:
The combustion reaction of the compound is
And the molar mass of CO2 and H2O are 44g/mol and 18g/mol respectively
All the mass of carbon producing the CO2 must come from the carbon of the unknown compound, thus it is necessary to calculate the moles of carbon in 4.4g of CO2
of Carbon
Also, all the mass of hydrogen producing the H2O must come from the hydrogen of the unknown compound, hence it is necessary to calculate the moles of hydrogen in 1.8g of water
of Hydrogen
