1. Why should a magnesium ribbon be cleaned before it is burnt in air?

Answer

Magnesium is a very reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper for removing this layer so that the underlying metal can be exposed to air.

Scholarships For College Students In India

Scholarships For College Students In India

Loans, scholarships and grants are important resources for college students seeking to make ends meet.  At the end of the day, college students rely on financial aid packages that contain all three types of financing.

Loans get the job done, but even though interest rates are low for college students, the money needs to be paid back eventually.  Grants and scholarships are coveted college cash sources, because the money you receive does not require repayment.

Grants are primarily need-based, reserved for students exhibiting the greatest levels of financial hardship paying for college.  Scholarships, on the other hand, usually reflect a high academic standard; so candidates are required to hold high grade point averages and do well on tests.



There are thousands of scholarship programs open to undergraduates, so qualifying may be easier than you think.   Your school’s financial aid office and your high-school guidance counselor are primary resources for up-to-date scholarship information.  Government agencies, professional associations, corporations and advocacy groups are all in the business of doling out scholarship dollars, so leave no stone unturned in your quest for college cash.
