D
Larger surface area speeds up reactions
Rust is an oxide so more oxygen should speed up rate of rust
Temperature also speeds up reactions
+ The humidity affects it aswell
PH3
Also known as phosphine
1L ------------ 1 kg
? ------------- 3.8 kg
3.8 x 1 / 1
= 3.8 L
The equation to calculate Density is Mass / Volume. You are given that the density is 5.45 and the mass is 65; 5.45 = 65 / v. So v = 65 / 5.45; v = 11.93 mL (or if you want your answer to consider significant figures, v = 12 mL).
