Correct Answer: Steel
Explanation:
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.
Correct Answer: Holograms
Correct Answer: 25
Correct Answer: AB
Explanation:
In transfusions of packed red blood cells, individuals with type O Rh D negative blood are often called universal donors. Those with type AB Rh D positive blood are called universal recipients.
The immune system of a person with AB blood will accept blood from all possible donors, whether they have O, A, B, or AB blood. Since both A and B antigens are present in a person with AB blood, the recipient won't reject the blood. The body identifies that blood as "self" rather than "foreign."
Correct Answer: An ozone molecule contains one single bond and one double bond
Explanation:
Ozone molecule has one single bond and one double bond.
Correct Answer: O
Correct Answer: Distillation
Explanation:
The first step in the refining of petroleum is distillation i.e, the fractionation of crude oil in atmospheric and vacuum distillation towers.
The first process petroleum refinery is known as distillation. In this process, crude oil is heated and fed into a distillation column. As the temperature of the crude oil in the distillation column rises, the crude oil separates itself into different components, called "fractions." The fractions are then captured separately. Each fraction corresponds to a different type of petroleum product, depending on the temperature at which that fraction boils off the crude oil mixture.
Correct Answer: Matter
Explanation:
Anything that has Mass and takes up Space is called Matter.
Matter has some mass and occupies some space. Mass means the amount of matter in an object. Space occupied by an object is called its Volume.
The Study of Matter and and how matter changes is called Chemistry.
