Answer:
Guard cells. The guard cells also contain chloroplast.
The answer would be 380 !
Answer:
unchanged
Explanation:
The density of an object or of a substance is independent of the amount of substance. From the definition of density as mass per unit volume, the ratio of the mass of an object to the volume of the same object is always constant. The more the mass of the object, the more the volume, and vice-versa.
<u>Hence, if a brownie that measures 15 cm by 7 cm by 7cm and has a density of 2.3 g/cm^3 is cut into half, both the mass and the volume would change in equal proportion and the density would remain the same.</u>
Answer:
tetrahedral
As carbon has no 4 valence electrons that are occupied by 4 chlorine atoms, we get 0 lone pair in carbon and sp3 hybridisation which leads to tetrahedral shape.
This problem can be solved by using ideal gas equation PV=nRT. The unit used in the pressure is kPa so you will need to convert it. The temperature also use Kelvin, you will need to convert it if you want it in C.
The calculation would be:
PV= nRT
16.4 atm * (101.35kPa/atm) * 18.35 L = <span>12.2 </span>mol *T * (8.314 L*kPa/mol*K)
T=30500 /101.4308
T= 300.70 °K = 27.55 °C
