Who invented chemistry?
Antoine-Laurent de Lavoisier (1743–94) is considered the "Father of Modern Chemistry".
What will happen without chemistry?
Without chemistry people would die much younger from diseases such as bubonic plague, since we wouldn't have antibiotics. We wouldn't have vaccines, so people would still contract terrible illnesses such as smallpox and polio. Even a simple skin infection might lead to death.

Why do we need chemistry in our life?
Chemistry is essential for meeting our basic needs of food, clothing, shelter, health, energy, and clean air, water, and soil. Chemical technologies enrich our quality of life in numerous ways by providing new solutions to problems in health, materials, and energy usage.
How is chemistry used in food?
Chemical substances can play an important role in food production and preservation. Food additives can, for example, prolong the shelf life of foods; others, such as colours, can make food more attractive. Flavourings are used to make food tastier. Food supplements are used as sources of nutrition .

What is the hardest question in chemistry?
Answer: which has more calories : table sugar or aspartame ? what does synthetic gas (water gas) consist of ?
What is chemistry short answer?
Chemistry is the branch of science that deals with the properties, composition, and structure of elements and compounds, how they can change, and the energy that is released or absorbed when they change.
What is the study of matter and energy?
Chemistry is the study of matter and energy and the interactions between them. It is a physical science that is closely related to physics, which often shares the same definition. Chemistry traces its roots back to the ancient study of alchemy.
What is the first element in the periodic table?
The first element in the periodic table is hydrogen. Each element in the periodic table has a one or two-letter symbol. The only letter in the English alphabet not used on the periodic table is J. The letter Q only appeared in the symbol for the placeholder name for element 114, ununquadium, which had the symbol Uuq.
What are some interesting facts about chemistry?

What is the name of the element that glows in the dark?
Many radioactive elements actually glow in the dark. The chemical name for water (H 2 O) is dihydrogen monoxide. The only letter not appearing on the periodic table is J. Lightning strikes produce O 3, which is ozone, and strengthen the ozone layer of the atmosphere. The only two non-silvery metals are gold and copper.
How many pencils does the human body have?
The human body contains enough carbon to provide "lead" (which is really graphite) for 9,000 pencils. Hydrogen is the most abundant element in the universe, while oxygen is the most abundant element in the Earth's atmosphere, crust, and oceans (about 49.5%). 4 .
What was the first element in the universe?
At ground zero, during the Universe’s singularity, the very first chemical element was hydrogen. All the other followed by fusing hydrogen into helium, which then fused into carbon and so on. Approximately 73% of the mass of the visible universe is in the form of hydrogen. Helium makes up about 25% of the mass, and everything else represents only 2%. By mass, hydrogen and helium combined make up less than 1% of the Earth.
How old is every hydrogen atom in the human body?
5. Every hydrogen atom in your body is likely 13.5 billion years old because they were created at the birth of the universe.
What temperature does helium transition?
A remarkable transition occurs in the properties of liquid helium at the temperature 2.17K (very close to absolute zero), called the “lambda point” for helium. Part of the liquid becomes a “superfluid”, a zero-viscosity fluid which will move rapidly through any pore in the apparatus. 7.
What does the water molecule look like?
If you remember your Chemistry 101, the water molecule looks like Mickey Mouse, the oxygen atom sitting at the center (the face) and two hydrogen atoms each at an angle (Mickey’s ears).
What is the most beautiful molecule?
The football-shaped carbon cluster C 60 has been called ‘the most beautiful molecule’, and if you have an eye for symmetry it’s easy to understand why. But if you ever liked chemistry in school, or actually have a career working in chemistry, you know chemistry goes beyond ‘beauty’.
Is glass a liquid or solid?
In a glass, molecules still flow, but at a very low rate that it’s barely perceptible. As such, it’s not enough to class glasses as a liquid, but neither as a solid. Instead, chemists classify glasses as amorphous solids— a state somewhere between those two states of matter.
