Nitrogen tribromide is a chemical compound with the formula NBr3. It is extremely ... NBr3 was first prepared by reaction of bistrimethlysilylbromamine (bis(trimethylsilyl) amine bromide) ..
<span>Mole ratios are important to stoichiometric calculations because they bridge the gap when we have to convert between the mass of one substance and the mass of another.</span>
Periodic table is a table of elements arranged in periods and groups in terms similar chemical and physical characteristics.The ion charge of an element depends on the number of electrons may loose or gain to form a stable ion. Elements in group iv have four electrons in the outermost energy level, therefore their ionic charge would be +4 or - 4 since they can gain or loose 4 electrons to form ions.
Answer:
C
Explanation:
Thermal energy from the fire move to the water in the form of heat.
Answer:
Fe(NO₃)₃ + 3NaOH → Fe(OH)₃ + 3NaNO₃
382.5 grams of NaNO₃ are formed, initially from 1.5 moles of Fe(NO₃)₃
Explanation:
This is the reaction:
Fe(NO₃)₃ + 3NaOH → Fe(OH)₃ + 3NaNO₃
Ratio is 1:3
So 1 mol of iron(III) nitrate is needed to produce 3 moles of sodium nitrate
1,5 moles of Fe(NO₃)₃ will produce (1.5 . 3) = 4.5 moles of NaNO₃
Molar mass of sodium nitrate: 85 g/m
Mol . molar mass = grams → 4.5 m . 85 g/m = 382.5 grams
