Answer:
see explanation
Explanation:
The reaction has a negative rate law; i.e., Rate = - ΔConcentration / ΔTime which is graphically a negative slope for the plot of Rate as a function of reactant concentration. => Rate ∝ f(Reactant Concentration). However, by raising the temperature, an increase the probability of reaction occurs and the formation of more product.
Purely for crystalline structure, "twinning" or repetition of crystal forms can bring about a striated texture on the mineral. Crystal defects and chemical impurities can alter the physical and electrical properties of a mineral. Some minerals can exist in different crystal forms and exhibit "polymorphism." The range in crystal structure can change the mineral's hardness, strength, solubility, electrical properties, melting points, etc.
It is physical change because ? has changed alone not with chemicals
Answer:
Synthesis
Explanation:
Two reactants are becoming one product, so it is a synthesis reaction.
Decomposition is the opposite, so when one molecule becomes simpler atoms.
Example: 2NaCl -> Cl2 + Na
Combustion is reaction with a product of water and carbon dioxide.
Example: CH4 + 2O2 -> CO2 + 2H2O
Single displacement is when one atom takes the place of the other.
Example: K + NaCl -> KCl +Na (where K took the place of Na)
Double displacement is like single displacement but it happens twice. Think of it like the atoms exchanging partners.
Example: HCl +NaH -> NaCl + HOH
Answer:
<h2>Physics</h2>
Explanation:
This definition was given by Isaac Newton.
He defined three "Laws of Motion" that describe what happens when forces act on objects
