Three blocks of the same mass are placed in front of you. Block A has a volume of

Ivan

Given :

Three block of same mass name A , B and C .

Sides of block A , B and C is 3.0 cm , 5.0 cm and 10.0 cm .

To Find :

Which block has the higher density .

Solution :

We know , density $\rho$ is given by :

$\rho=\dfrac{M}{V}$ ......1 )

Here , V is volume .

Now , volume V for cube is given :

$V=a^3$ .......2 )

( Here , a is the side of cube )

Now ,form equation 1 we can see if mass remains constant then density decrease with increase in volume.

Therefore , cube with minimum side will have higher density , in this case it is 3 cm block .

Hence , this is the required solution .

Answer:

<u>Question</u><u> </u><u>1</u><u> </u><u>:</u>

• A compound is ionic if it is made up of a metal or a cation (+) and a non metal or anion (-)

<u>Question</u><u> </u><u>2</u><u> </u><u>:</u>

• While naming ionic compounds, follow the formula → "metal" + "non-metal ending with <em>ide</em><em> </em>"

• i.e; Sodium Chloride:

${ \rm{Na {}^{ + } _{(aq)} + Cl {}^{ - } _{(aq)} \: \dashrightarrow \: NaCl _{(aq)}} \: \: \: \: \: \: \: \: } \\ { \rm{sodium + chloride \: \dashrightarrow \: sodium \: chloride}}$

<u>Question</u><u> </u><u>3</u><u> </u><u>:</u>

• The answer above that question is perfect.

<u>Question</u><u> </u><u>4</u><u> </u><u>:</u>

1 atom → Mono. But it is highly recommended to ignore it

2 atoms → DI

3 atoms → TRI

4 atoms → TETRA

5 atoms → PENTA ( such as pentaoxide )

7 atoms → HEPTA ( such as heptaoxide )

<u>Question</u><u> </u><u>5</u><u> </u><u>and</u><u> </u><u>6</u><u>:</u>

Are perfectly answered.
