5 0

Answer : The correct option is, (3)

Explanation :

Isomers : It is defined as the molecule that has the same chemical formula but  it has the different structures.

Same chemical formula means that the same number of elements are present in both the compounds.

In option 1,2 and 4, both chemical formula and the structure are different. So, the option 1 compounds are not the isomers of each other.

In option 3, the chemical formula is same but the structure are different. So, the option 3 compounds are the isomers of each other.

Hence, the correct option is, (3)

horsena [70]

Answer:

Mass = 208.26 g

Explanation:

Given data:

Volume of water = 40.0 mL

Volume of water + copper = 63.4 mL

Volume of copper = ?

Density of copper = 8.9 g/cm³

Mass of copper = ?

Solution:

Volume of copper:

Volume of copper = (Volume of water + copper ) - Volume of water

Volume of copper =  63.4 mL -  40.0 mL

Volume of copper = 23.4 mL

Mass of copper:

density = mass/volume

8.9 g/cm³ = mass/23.4 mL

 cm³ = mL

Mass = 8.9 g/mL × 23.4 mL

Mass = 208.26 g

How many types of atoms in this picture?
weqwewe [10]

Answer:

Nitrogen (N), carbon (C), hydrogen (H) and oxygen (O).

Explanation:

Hello,

Given the shown organic compound, we refer to types of atoms to the elements present in the compound, thus, we find nitrogen (N), carbon (C), hydrogen (H) and oxygen (O) that are bonded via single or double bonds in such compound.

Let's remember that compounds like that, having those elements are mainly found in biochemical substances such as proteins, a very important source of benefits for our body.

Regards.
