Answer:

the correct option is D.

Explanation:

ionic bond:

ionic bond is a bond where one of the atom donates one or two electron to one or more than one atom for all the atom to attain stability that is octet.

chlorine has 17 electrons so the outer most orbit has 7 electron for it to obtain stability it has to gain one more electron while magnesium has 12 electrons so it has to lose 2 electrons to gain stability so if a magnesium atom loses 2 of its electron to two chlorine atoms  botn the chlorine will have 18 electron and magnesium will have 10 electron therefore every atom attaining octet. by this way magnesium forms ionic bond with two chlorine atom to form MgCl2.

so option d must be correct.

arrow_backSources of Information on Modern Indian History

Summary

Videos

References

A primary source of information for historians is the official records of the British administration. The British kept written records of every key instruction, meeting, transaction, investigation, plan, policy decision and agreement. They attached record rooms with all the important administrative institutions.

The British built specialized institutions like museums and archives to preserve important documents.

Historians gather important information about the provincial administrative system from the reports, memos, notings and letters preserved in the 19th century in the archives and record rooms across India.

For effective administration, the British carried out a number of surveys in the early 19th century.

By the end of the 19th century, censuses of all the Indian provinces were being carried out every ten years. This helped to collect information on the religion, caste and occupation of the people. These surveys have helped historians to collect information about modern India.

Personal diaries of personalities like Jawaharlal Nehru and Sardar Vallabhbhai Patel, newspapers, popular books like The Discovery of India and Glimpses of World History, autobiographies of personalities like Mahatma Gandhi, and accounts of travellers and pilgrims give a deep insight into the lives of the common people.

How many grams of propane, C3H8, are needed to make 140 grams of water?
Marizza181 [45]

Answer:

85.6 g

Explanation:

Step 1: Write the balanced combustion equation

C₃H₈ + 5 O₂ ⇒ 3 CO₂ + 4 H₂O

Step 2: Calculate the moles corresponding to 140 g of H₂O

The molar mass of H₂O is 18.02 g/mol.

140 g × 1 mol/18.02 g = 7.77 mol

Step 3: Calculate the moles of C₃H₈ needed to produce 7.77 moles of H₂O

The molar ratio of C₃H₈ to H₂O is 1:4. The moles of C₃H₈ needed are 1/4 × 7.77 mol = 1.94 mol.

Step 4: Calculate the mass corresponding to 1.94 moles of C₃H₈

The molar mass of C₃H₈ is 44.10 g/mol.

1.94 mol × 44.10 g/mol = 85.6 g

Why would a crash involving cars going faster do more damage than a crash going slow? explain using terms kinetic and potential
erastovalidia [21]

At high speeds, there is more kinetic energy involved - more energy that will be converted to other forms of energy. This includes breaking a car, or body parts of people involved.
