With a passion for chemistry ignited at Hope College, my journey into the intricacies of matter began. Armed with knowledge and enthusiasm, I'm here to guide you through the world of atoms and molecules. From balancing equations to exploring the wonders of organic chemistry, I'm committed to making complex concepts clear. Let's unravel the mysteries of science together, one question at a time.
