Ans: the point at which chemically equivalent quantities of bases and acids have been mixed
Ques: The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of bases and acids have been mixed. In other words, the moles of acid are equivalent to the moles of base, according to the equation (this does not necessarily imply a 1: 1 molar ratio of acid: base, merely that the ratio is the same as in the equation). It can be found by means of an indicator, for example phenolphthalein or methyl orange.

Answer this question based on the passage: when do we reach the equivalence point in the acid-base titration?
CoT: To answer the above question, the relevant sentence is: The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of bases and acids have been mixed.

Ans: brightness as seen by an observer on Earth
Ques: The apparent magnitude (m) of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth. The brighter an object appears, the lower its magnitude value (i.e. inverse relation). The Sun, at apparent magnitude of 27, is the brightest object in the sky. It is adjusted to the value it would have in the absence of the atmosphere. Furthermore, the magnitude scale is logarithmic; a difference of one in magnitude corresponds to a change in brightness by a factor of 100, or about 2.512.

Based on this passage, the apparent visual magnitude of a star is a measure of the star's?
CoT: The relevant sentence in the passage is: The apparent magnitude (m) of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth.

Ques: A revised model of the Vita was released in Japan on October 10, 2013, in Europe on February 7, 2014 and in North America on May 6, 2014. The revised model, officially called the PCH-2000 series and commonly referred to as the PS Vita Slim, is 20 % thinner and 15 % lighter compared to the original model. While it largely maintains the original's overall structure and layout, the original's OLED screen has been replaced with a lower-cost LCD display. The model also roughly added about an extra hour of battery life. The newer model also comes with 1 GB of internal storage memory, although it is not possible to use both the internal memory and memory card concurrently. Upon inserting a PS Vita memory card, the system will offer to copy the existing data from the internal memory to the new card. This model has a micro USB Type B port, which can be used to charge the device along with any standard micro USB cable. The model was released in six colors in Japan (white, black, light blue, lime green, pink, and khaki), although it was only released in black and light blue in North America and Europe.
