Answer:
Sr(NO3)2 + Na2CO3 --------> SrCO3 + 2NaNO3
Total ionic equation;
Sr^2+ + NO3^- + Na^+ + CO3^2- -----> SrCO3 + 2NaNO3
Net ionic equation;
Sr^2+ + CO3^2- -----> SrCO3
Explanation:
The molecular equation shows the reactions of the compounds to give the products. It shows the molecular formula of reactants and products.
The total ionic equation shows the ions that recombine to form the products of the reaction.
The net ionic shows the major ionic reaction that took place in the system.
Hence, the net ionic equation explicitly shows the major species that are involved in a reaction, while a complete ionic equation includes the spectator ions.
Answer: A) NO increases the rate at which 
molecules are formed.
Explanation:
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more reactant molecules can cross the energy barrier by undergoing collisions and convert to products.
Thus NO will increase the rate of reaction by lowering the activation energy and thus the colllisions among 
and 
molecules will incraese which in turn will lead to formatioon of more molecules.
To determine the mass of xenon tetrafluoride, we need to know first the number of fluorine atoms present in <span>oxygen difluoride. We need to convert first the mass into moles then make use of the relation of the elements from the chemical formula. Then, use the avogadro's number to convert it to number of atoms. Then, we do the reverse of the steps above but this time for </span><span>xenon tetrafluoride.
25.0 g OF2 ( 1 mol / 54 g ) ( 2 mol F / 1 mol OF2 ) ( 6.022 x10^23 atoms F / 1 mol F ) ( 1 mol / 6.022x10^23 atoms) ( 1 mol XeF4 / 4 mol F ) (207.3 g / 1 mol XeF4) = 47.99 g XeF4</span>
Answer:
False
Explanation:
Flammability is a chemical property that tells whether a substance reacts in the presence of extreme heat, spark, or another form of ignition.
