<span>a) Table salt: it is a compound. A compound is a combination of atoms in fixed proportions.Table salt is NaCl, which means that table salt is a compound of 1 atom of Na and 1 atom of Cl and not other thing. b) Blood: is an homogeneous mixture: it is a mixture of many compounds which can not be easily distinguished or separated, you need microscopes or very special physical methods to distinguish or separate the different compounds of blood. d) Steel: it is a special king of homogeneous mixture (it is called an alloy) which, as in the case of blood, cannot be distinguished or separated easily. d) Planet earth: it is a heterogeneous mixture. You can easily distinguish many of the compounds of the planet Earth: water, oxygen, carbon,...</span><span />
Answer:
H3PO4 + 5 HCl → PCl5 + 4 H2O
Explanation:
The given equation is
H3PO4 + HCl = PCl5 + H2O
The above chemical equation has one P atom on both the sides, hence phosphorus is balanced
There are 5 Cl on the RHS but only one Cl on the LHS. On balancing the chlorine, we get -
H3PO4 + 5HCl = PCl5 + H2O
Now, there are 8 hydrogen atom on the LHS but only two on the RHS. On balancing the hydrogen on both the sides, the new equation become
H3PO4 + 5HCl = PCl5 + 4H2O
Let us check for oxygen
Oxygen on LHS = 4 and oxygen on RHS = 4
Thus, the balanced equation is H3PO4 + 5HCl = PCl5 + 4H2O
Answer:
No, because even if you cut the tree into small pieces it’s still a tree.

Answer:
Tantalium is a Transition metal.
Osmium is a Transition metal.
Thorium is radioactive Metal.
Answer: <span>Yes, a hydrocarbon is any compound that contains hydrogen and oxygen.
Justification:
First, I will try to rewrite the given structural formula since it is misrepresented.
This should be the right structural formula:
H H
| |
H - C - C - OH
| |
H H
And, yes the definition of hydrocarbon is that it is most simple organic compound constitured only by atoms of carbon (C) and hydrogen (H).
By the way, that hydrocarbon is also represented as CH3 - CH2 OH, it is an alcohol (since it has the functional group OH) and its name is ethanol.
