Molecules of elements

Explanation:

The balls that looks alike showing atoms of the same type shows molecules of elements.

Molecules of elements are those produced from pure substances whose atoms are the same.

They are called homonuclear molecules.

They are homonuclear in that they are made up of the same atom. These molecules of zero electronegativity differences between them.

They are non-polar.

A 100. g iron rod is heated to an unknown initial temperature. While cooling down to a temperature of 25.0 degree C, the rod rel
AfilCa [17]

Answer: a)  38.3^0C

Explanation:

As we know that,  

q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})

where,

q = heat released  = -600.2 J

m = mass of iron rod =100 g  

T_{final} = final temperature =25.^0C

T_{initial} = initial temperature = ?

c = specific heat of iron = 0.452J/g^0C

Now put all the given values in equation, we get

-600.2J=100\times 0.452J/g^0C\times (25.0-T_{initial})^0C]

T_{initial}=38.3^0C

Therefore, the initial temperature of iron rod was 38.3^0C

How do alpha particles compare to gamma rays?
Fofino [41]

Answer:

Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.

How many atoms are in one body-centered cubic unit cell of a metal?
Mashcka [7]

Answer:

Option B - 2

Explanation:

In Crystal lattices, there are different types of unit cells namely;

- Hexagonal Closest Packed (HCP)

- Face Centred Cubic (FCC)

- Body Centred Cubic (BCC)

- Simple Centred Cubic (SC)

Now, each of them have a coordination number and also number of atoms per unit cell.

For this question, we are restricted to the body-centered cubic (bcc) unit cell which has a coordination number of 8 and contains 2 atoms per unit cell.
