“A class C fire is an energized electrical fire. ... “Class C” is a term that distinguishes a fire from class A and class B fires. Class A is a category for fires consuming a source like fire or wood that can be extinguished with water, and class B fires are fueled by flammable liquids like gasoline.”
Answer: 40.1%
Explanation: The mass of calcium in this compound is equal to 40.1 grams because there's one atom of calcium present and calcium has an atomic mass of 40.1 . The molar mass of the compound is 100.1 grams. Using the handy equation above, we get: Mass percent = 40.1 g Ca⁄100.1 g CaCO3 × 100% = 40.1% Ca.
Synthesis, decomposition, single replacement and double replacement.
Synthesis- two or more reactants unite to form a single product
S (Sulfur) + O2 (Oxygen) ——> SO2 (Sulphur dioxide)
Decomposition- A single reactant is decomposed or broken down into two or more
CaCO3 (Calcium Carbonate) ——> CaO (Calcium oxide) + CO2 (Carbon dioxide)
Single replacement- A single free element replaces or is substituted for one of the elements in a compound. The free element is more reactive than the one its replaces.
Zn (Zinc) + 2 HCI (hydrochloric acid) ——> H2 (hydrogen) + ZnCl2 (Zinc Chloride)
Double replacement- This reaction type can be viewed as an "exchange of partners." For ionic compounds, the positive ion in the first compound combines with the negative ion in the second compound, and the positive ion in the second compound combines with the negative ion in the first compound.
HCI (hydrochloric acid) + NaOH (sodium hydroxide) ——> NaCl (Sodium Chloride) + HOH (water)
Once reactants have absorbed enough heat energy from their surroundings to reach the transition state, the reaction will proceed. The activation energy of a particular reaction determines the rate at which it will proceed. The higher the activation energy, the slower the chemical reaction will be.
