Who are the classrooms to go to if Mr Anderson passes out or crashes out.
Ms Puga the Queen of Science or Ms Silva
State the Law of Conservation of Mass
Mass cannot be created or destroyed, only transformed.
What is a Coefficient
The big number before the element or the chemicals to show how much to multiply the number of atoms of an element by to get the correct amount
What is an Element?
An element is a fundamental substance made up of only one type of atom, meaning it cannot be broken down into simpler substances by ordinary chemical means. Each element is defined by its unique atomic number, which is the number of protons in its atoms' nuclei.
What is a Compound?
A compound is a pure substance formed when two or more different chemical elements are chemically bonded together in a fixed proportion
True or False, or false I can press the emergency button just because I want tol
During a chemical reaction in a sealed container, energy is released as heat. Explain how the Law of Conservation of Energy applies in this scenario. How can energy be conserved if heat is released outside the reaction system?
The Law of Conservation of Energy states that energy cannot be created or destroyed; it can only change forms.
In this scenario, the chemical reaction releases energy in the form of heat. Although heat is leaving the reacting system, the total energy of the entire closed system (reaction + surroundings) remains constant.
The energy released by the reaction is transferred as heat to the surroundings (e.g., the container, air).
The chemical potential energy stored in the reactants decreases, but the thermal energy in the surroundings increases by the same amount.
Therefore, energy is conserved overall because it just moves from chemical energy in the reactants to thermal energy in the environment.
Label and break apart this equation. Does it follow the Law of Conversation
NaCl2 O4 + NaCl2 4O
Yes it follows the law.
1 atom of Sodium, 2 atom of Chlorine, 4 atoms of oxygen.
is H2o a element
No it is a compound!
NACL
it is salt

In a closed chemical reaction, 12 grams of reactant A react completely with 8 grams of reactant B to form product C. After the reaction, the mass of product C is measured to be 19.5 grams. Explain why this result either supports or contradicts the Law of Conservation of Mass. What could account for the difference in mass if it contradicts the law?
According to the Law of Conservation of Mass, mass cannot be created or destroyed in a chemical reaction. Therefore, the total mass of reactants (12 g + 8 g = 20 g) should equal the total mass of products.
Since the mass of product C is measured as 19.5 grams, which is less than the total mass of reactants (20 grams), this result contradicts the Law of Conservation of Mass.
Is this lawful
C3H8+5O2→3CO2+4H2O
Yes,
Reactants: Carbon-3, Hydrogen-8, Oxygen-10
Products: Carbon -3, Hydrogen-8, Oxygen-10
