<span>Bleach and ammonia can be used to make cl2. Bleach is commercially available and so people should be very careful during these experiments or even when mixing things in the household.</span>
Answer:
The correct answer is b the magnitude of the concentration gradient of the molecule.
Explanation:
Dffusion is one of most important membrane transport process that allow several molecules such as gases oxygen and carbon dioxide to pass directly across the plasma membrane.The is no involvement of carrier proteins or ion channels during passive diffusion.
During passive diffusion molecules are transported along their concentration gradient that means from the region of high concentration to region of low concentration,until the concentration of both regions become same.
Answer:
B. Pluto's orbit is not clear of other objects
Explanation:
Pluto is a dwarf planet and considered as ninth planet of the solar system.
A large body whose orbit do not clear the neighbourhood is classified as a dwarf planet. The gravity of Neptune limit the orbit of Pluto and shares its orbital neighbourhood with many Kuiper belt objects.
Hence, the correct answer is "B. Pluto's orbit is not clear of other objects".
Answer:
0.375 moles of CaCO₃ are required
Explanation:
Given data:
Number of moles of sulfamic acid = 0.75 mol
Number of moles of calcium carbonate required = ?
Solution:
Chemical equation:
2H₃NSO₃ + CaCO₃ → Ca(SO₃NH₂)₂ + CO₂ + H₂O
Now we will compare the moles of H₃NSO₃ and CaCO₃ .
H₃NSO₃ : CaCO₃
2 : 1
0.75 : 1/2×0.75 = 0.375 mol
Thus, 0.375 moles of CaCO₃ are required.
