Answer:
D
Explanation:
--2 K (s) + __ H2SO3 (aq) --
-->
_K2SO3 (aq) + __H2
To balance this equation, all you need do is put a 2 in front of the K. The rest don't require any balancing coefficients.
Left
2 K
2 H
1 SO3
Right
K2
1 SO3
1 H2
It's balanced.
Answer:
C
Explanation:
Alcohols are organic molecules characterized majorly by the presence of the OH group in their molecule. The OH group is majorly responsible for several of their characteristics. This include the formation of hydrogen bonds between alcohol molecules. While this makes them more inorganic than most organic compounds, comparatively the hydrogen bonding formed in alcohols is not as strong as that which is present in water.
The higher strength of the hydrogen bonding is responsible for some comparable properties. While water boils at a temperature of 100 degrees Celsius, alcohol boils at a temperature of 78 degrees Celsius. This is an evidence to the fact that hydrogen bonding in alcohol is less stronger that that in water.
The correct answer is B. 50 feet divided by 3.28084 feet (1 meter).
Concentration of H+ ions in HNO3 solution is 10⁻¹ which is equal to 0.1 M
putting the value we get
So, the required option is A) 1
A. by lowering the activation energy
