0 1This question is about rates of reaction. 
Figure 1 shows apparatus used to measure the rate of reaction when an acid reacts 
with an excess of solid sodium hydrogencarbonate, NaHCO3 
When different monoprotic organic acids are used, the rates at which gas escapes 
can be used to compare the strengths of the acids. 
A timer is started when the NaHCO3 is added to the acid and

HOW CAN CYANIDE ENTER AND LEAVE MY BODY? 
Cyanide can enter your body if you breathe air, eat food, or drink water that contains it. Cyanide 
can enter your body through the skin, but this may occur only in people who work in 
cyaniderelated industries without adequate protective gear. You can be exposed to contaminated 
water, air, or soil at hazardous waste sites. Once it is in your lungs or stomach, cyanide can 
quickly enter the bloodstream. Some of the cyanide is changed to thiocyanate...
