Types of Bonds can be predicted by calculating the
difference in electronegativity.
If, Electronegativity difference is,
Less
than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For Na and Cl,
E.N of Chlorine = 3.16
E.N of Sodium = 0.93
________
E.N Difference 2.23 (Ionic Bond)
For C and O,
E.N of Oxygen = 3.44
E.N of Carbon = 2.55
________
E.N Difference 0.89 (Polar Covalent Bond)
For N and Cl,
E.N of Chlorine = 3.16
E.N of Notrogen = 3.04
________
E.N Difference 0.12 (Non-Polar Covalent Bond)
For B and O,
E.N of Oxygen = 3.44
E.N of Boron = 2.04
________
E.N Difference 1.40 (Polar Covalent Bond)

<h3>What is a fibrous root?</h3>
A fibrous root system is a root system which consists of large mass of roots of nearly equal size
Some few examples of plants with fibrous roots system are as follows:
- Rice plants
- Sugarcane plants
- Onions
- Pines
- Asparagus
- Maize
In conclusion; the plants which have a fibrous root system are grasses and corns.

Explanation:
A microscope is a laboratory tool that is used to <u>magnify the image of objects</u> This allowed scientists to <u>study tiny organisms that cannot be seen with an ordinary eye</u>. We cannot see some organisms using our naked eyes, such as <u>bacteria,</u> protists, <u>viruses,</u> and <u>microscopic fungi.</u> The main parts of a microscope that magnifies are the <u>ocular</u> and the <u>objective lenses</u>. the <u>lamp </u>serves as the light source. In order to see the specimen clearly the stage needs to be adjusted at the right distance from the lens. this is done using the <u>coarse</u> and <u>the fine adjustment knobs</u>. other parts of the microscope such as the <u>base</u> and <u>the arm</u> serve as primary support for the device.
The microscope is primarily designed to magnify the image of objects and, thus, enables one to see objects that cannot ordinarily be seen with the naked eyes. It magnifies objects using a system of lenses in the ocular and the eyepiece. Microscopic organisms such as protists, bacteria, viruses, microscopic fungi and algae can be seen using the microscope. Slides of objects are prepared and placed on the stage of the microscope and the coarse/fine adjustment knobs used to adjust the stage in order to bring the image on the slide into focus through the ocular. A lamp at the base provides the light source for the light microscope while other parts such as the arm, the head, and the base provide supportive functions for the microscope,

Explanation:
Answer:
mi = 31.28 g
Explanation:
According to the law of conservation of energy:
where,
mi = mass of ice = ?
L = Latent heat of fusion of ice = 334 J/g
mw = mass of water = 50 g
C = specific heat of water = 4.18 J/g.°C
ΔT = change in temperature of water = 75°C - 25°C = 50°C
Therefore,
<u>mi = 31.28 g</u>
