As we inhale air, oxygen enters the respiratory system and the circulatory system to transport it to the other parts of the body and to all cells. As the oxygen is already transported, the blood becomes deoxygenated and carries a CO2 which returns to the lungs and then we exhale the carbon dioxide.

romanna [79]

Answer:

d. The pH of the beaker`s contents will decrease.

Explanation:

Since the new substance is an acid and has a very low pH, that is 1. it will reduce a little bit the pH of the original base (NaOH). Some ions of hydrogen of the acid are going to react with the hydroxyl group of the sodium hydroxide to form water.

Since the differences of the volume is big, only a small part of the base is going to be neutralize, but at the end, the final pH of the solution is still going to be  a base.

Hope this information is useful.

More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.

Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.
