For the hypothetical compound AX3, which statement is true? (Need help ASAP)

A is a metal from Group 3A, and X is a nonmetal from Group 7A.

A is a metal from Group 1A, and X is a metal from Group 7A.

A is a nonmetal from Group 3A, and X is a metal from Group 1A.

A is a metal from Group 3A, and X is a nonmetal from Group 5A.

43.452

step-by-step explanation:

284 times .153 = 43.452

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

catya that's not even a b or c

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
