Is sugar solution a compound?
Compounds : It is a pure substance made up of two or more elements chemically combined in a fixed proportion by mass. So, (e) calcium carbonate, (k) methane and (l) carbon dioxide are compounds. So (b) soil, (c) sugar solution, (h) coal, (i) air, (j) soap and (m) blood are mixtures.
Why Glucose is not a mixture?
Answer:There are no other things mixed in it, so it is a pure substance. (Mixtures are two or more substances mixed together.) Every grain of sugar has near it only another grain of sugar. There are no other substances mixed in it.
Does Br2 have ionic and covalent bonds?
c) Bromine and bromine form covalent bonds because bromine is a non-metal and each atom must share electrons in order to satisfy the octet rule. IOnic bonds form as a result of the transfer of electrons from one atom to another. …
What is the difference between an element and a compound?
Compound vs. Element. Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions.
What is the name of the compound Br2?
