Answer:
See explanation
Explanation:
Freezing point and melting point increases slightly at higher altitude
The boiling point decreases at higher altitudes.
Air pressure decreases with altitude As a result of this, atmospheric pressure decreases and water must now boil at a lower temperature. In order to compensate for this lower boiling point of water, food must take a longer time to cook. The lowering of air pressure actually means that the air becomes thinner at higher altitudes.
Pressure cookers cook food at high pressure thereby reducing the cooking time significantly. This helps to retain 50% of the nutrients in the food, lower the kitchen temperature and lower the energy cost required to cook food.
Answer:
The statement about the nuclear envelope which is false is D - The nuclear envelope is continuos with the Golgi apparatus.
Explanation:
The nuclear envelope is composed of two membranes pierced by pores. They are distributed throughout the entire surface of the envelope and are much more than perforations in which both external and internal membranes are continued. Inside the pores a set of proteins form a structure called NPC where the smallest molecules pass, since the larger ones require energy input. The nuclear envelope that is reinforced by filaments, its two bilayers are continued with the endoplasmic reticulum membrane system.
Answer:
1.75 mol of Cu
Explanation:
all you have to do is divide 3.50 by 2 because you need half moles from Ag
Answer:
Sorry I'm not sure about this one. It might be The first one or the third one
Answer : The correct option is, (2) Cr (Chromium)
Explanation :
The reactivity series of metal are arranged of the reactivity from the highest to the lowest. Reactivity series is used to determine the products of the single displacement reactions. In the single displacement reaction, the most reactive metal displaces the least reactive metal.
From the given reactivity series we conclude that there are two metal (Mg and Cr) are more reactive metal than the Ni and there are two metal (Pb and Cr) are less reactive metal than the Zn. So, the Cr (Chromium) is the metal which is more active than Ni and less active than Zn.
Hence, the correct option is, (2) Cr
