Answer: mass of SO2 is 160 g
Explanation: according to equation number of moles of SO2
Is same as amount of Oxygen, also 2.5 moles.
Molar mass of SO2 is 32.07 +2·16 = 64.07 g/mol
Mass is m= nM = 2.5 mol· 64.07 g/mol= 160.175 g
Answer: HOPE IT HELPS! PLS MARK AS BRAINLIEST
Explanation: The respiratory pigment, haemoglobin in red blood cells have a very high affinity of oxygen. It combines with oxygen to form oxyhaemoglobin and thus oxygen is carried from lungs to various body parts. Carbondioxide is highly soluble in water so it is mostly transported in dissolved form in our blood plasma.
Answer:
Physical: Conducts Electricity, Magnetic, Malleable and ductile
Chemical: Rusting, reacts with acid
Explanation:
The reason, why I categorized the listed items as "Physical" was because there is no major change, no matter if it is magnetic, malleable, etc. The item is still in its original form.
Whilst the reasons I put rusting, and reacting with acid as chemical, is because when an item rusts, you can no longer change it back to its original state, and when you an item reacts with the acid, at times (depending on the metal, it will create or form compunds)
Answer: 2. Decomposition
Explanation:
Synthesis reaction is a type of chemical reaction in which two reactants combine to give a single product.
Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.
lithium carbonate → lithium oxide + carbon dioxide
Single replacement reaction is a type of chemical reaction in which more reactive element displaces the less reactive element from its salt solution.
A double replacement reaction is one in which exchange of ions take place.
Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances
