Answer:
Water-gas A mixture of carbon monoxide (CO) and hydrogen (H2) produced by passing steam over red-hot coke using the endothermic reaction C + H2O # CO + H2.
Explanation:
We are asked to solve for the arc length of the intercepted arc and the formula is shown below:
Arc length = 2*pi*r(central angle/360°)
r = 5 feet
central angle = 10°
Solving for the arc length, we have:
Arc length = 2*3.14*5 (10/360)
Arc length = 0.872 feet
The arc length is 0.872 feet.
Answer: Weak acids are poor conductors of electricity.
Explanation:
Weak acids are defined as the acids which dissociate weakly or partially when dissolved in water (polar solvent).
For example, 
Due to less dissociation there will be less number of ions present in a solution of weak acid. As a result, a weak acid will be poor conductor of electricity.
As electricity is the flow of ions.
Thus, we can conclude that weak acids are poor conductors of electricity.
