Answer: option B. 5g
Explanation:
50mL of H2O dissolves 25g of CaCl2.
Therefore, 10mL of H2O will dissolve Xg of CaCl2 i.e
Xg of CaCl2 = (10 x 25) /50 = 5g
Iodine dissolves easily in chloroform and hexane but does not dissolve in water. When polar and non-polar are mixed, water finds other water and forms spherical bubbles. When mixed with hexane, the iodine molecules experience London dispersion forces. There is no induced polarity in the iodine molecules and they exhibit their typical violet color in the solution. (Note: The color may be pink if the iodine concentration is low.) Hope this helps!!
The Gulf Stream affects the climate in Britain by bringing warm water from the Caribbean to North West Europe. This keeps the climate in Britain warmer than other places at a similar latitude.
Answer is: there is 1,368·10²⁵ atoms of carbon.
N(C₃H₈) = 4,56·10²⁴.
From molecular formula: in one molecule of propane there is three atoms of carbon:
N(C) = 3 · 4,56·10²⁴.
N(C) = 1,368·10²⁵.
Answer:
The limiting reactant is B.
Explanation:
The equation for the reaction is given below:
2A + 3B —> C + D
The limiting reactant can be obtained as follow:
From the equation above,
2 units of A reacted with 3 units of B.
Therefore, 5 units of A will react with = (5 x 3) /2 = 7.5 units of B.
From the calculation made above, we can see that it will take a higher unit of B i.e 7.5 units than what was given i.e 6 units to react completely with 5 units of A.
Therefore, B is the limiting reactant and A is the excess reactant.
