How do scientists represent chemical reactions?
Scientists represent chemical reactions using chemical equations, where reactants are on the left side and products on the right side. The equation includes the chemical formulas of the substances involved and coefficients representing the mole ratios of reactants and products. Symbols like arrows indicate the direction of the reaction.
When can a compound be treated like element when balancing chemical equations?
A compound can be treated as an element when balancing chemical equations if it is a polyatomic ion that remains unchanged throughout the reaction. This is done to simplify the equation by treating the polyatomic ion as a single entity, similar to how an element is treated.
How do chemical equations account for the different states of matter of reactants and products?
Chemical equations show the states of matter of reactants and products by using symbols like (s) for solid, (l) for liquid, (g) for gas, and (aq) for aqueous solutions. This helps to accurately represent the physical state of each substance involved in the reaction.
What is the abbreviation for the element iodine?
The chemical symbol for iodine is I. So for compounds like silver iodide, we denote them as AgI. Abbreviations make it easy for us to represent and identify elements in chemical formula and equations.
What do scientists call different types of atoms like carbon hydrogen and nitrogen?
Scientists refer to different types of atoms like carbon, hydrogen, and nitrogen as elements. Each element is defined by the number of protons in its nucleus, which determines its unique chemical properties.
Do chemical equations have no real structure?
Chemical equations provide a written representation of a chemical reaction by showing the relationship between reactants and products. While they do not have a physical structure like molecules, they are structured to follow the law of conservation of mass and allow scientists to understand the stoichiometry of a reaction.

Why did scientists revise bohrs model?
Scientists determined that electrons do not orbit the nucleus like planets. Instead, electrons can be anywhere in a cloud like region around the nucleus
Why do scientists use schematic circuit diagrams instead of drawing a picture?
It is a lot easier and quicker. Especially if scientists cannot draw (like me)

What can you use instead of chemical energy?
a non uncontroled subject like water
What are some chemical equations on hydrogen?
hydrogen gas is produced through chemical reactions like: Mg+H2SO4=H2+MgSO4 The general equation is : metal + acids = hydrogen + salt.
How are functions like linear equations?
Most functions are not like linear equations.

What is the symbol for the element Strontium?
the strontium symbol in a periodic table is sr.
