i agree with nh4cl ○ Reasoning? ○ if it was nh4no3 it would not form precipitate when you add agno3 im pretty sure ○ What else can we say about NH4Cl? ○ was there bubbles with hcl? if so‚ then it can be co3 2 (carbonate) ● Unknown 6 ● KOH ○ basic ○ flame test ○ did not react with naoh therefore it can contain oh‚ i guess ● Unknown 7 ● HCl ○ ○ ○ ○ ● Unknown 8 ● Ca(OH)2 ○ was soluble with naoh therefore

Biodiesel It refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl‚ propyl or ethyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g.‚ vegetable oil‚ animal fat (tallow[1][2])) with an alcohol producing fatty acid esters. Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone‚ or blended with petro diesel
