Is sand macromolecule or network solid? Thank you

A macromolecule is a molecule with lots and lots of atoms. (i.e. protein, nucleic acid...)
A network solid is <span>is a chemical compound where the atoms are "bonded by covalent bonds in a continuous </span>network<span> extending throughout the material."
A single grain of sand consists of, on average, </span><span>~50,000,000,000,000,000,000 atoms.
That's A LOT.
However, these atoms do bond in network covalent bonds.
But that means it's a covalent network solid.
The short answer is that sand is both a </span><span>macromolecular substance as well as a covalent network solid, so I would go with it's macromolecular but you can interpret that the way you want.</span>

The density of osmium, which is the densest metal, is 22.57 g/cm^3. What is the mass of a block of osmium that measures 1.00 cm
olganol [36]
Density = Mass / Volume
V = 1.00 * 4.00 * 2.50 = 10 cm³
22.57 g/cm³ = Mass / 10 cm³
M = 22.57 g/cm³ * 10 cm³
M = 225.7 g
Answer: The mass of the block of osmium is 225.7 g.

Which of the following are acids by the Bronsted-Lowry Definition:
olga55 [171]

ANSWER IS (A)

EXPLANATION:

Bronsted-Lowry concept states that a substance is an acid if it can act as a H+ donor.

HCl in aqueous solution means that HCl is present in water, HCl + H2O --> H3O+ + Cl-.  This reaction will take place, the H+ from HCl will be donated to H2O. So, HCl is a bronsted-lowry acid by definition.


However, Methanol (CH3OH) its written that it is liquid, i.e. pure methanol, CH3OH(l).  It is both acidic as well as basic. when it is mixed with water then it behaves as an acid.

The last one ammonia in gas phase is also neutral because its not in water. if mixed in water it behaves as a base.

For Mn3+, write an equation that shows how the cation acts as an acid.
Mkey [24]

An acid is a compound which will give H+ ions or H3O^+  ions

the reaction will be

[Mn(H_{2}O )_{6} ^{+3} +H_{2}O --> [MnOH(H_{2}O)_{5}]^{+2} + H_{3}O^{+}

Thus as there is evolution of H_{3}O^{+} the Mn+3 is an acid
