Soda and lime are added to a glass batch in the form of soda ash (na2co3) and limestone (caco3). during heating, these two ingredients decompose to give off carbon dioxide (co2), the resulting products being soda and lime. compute the weight of soda ash and limestone that must be added to 100 lbm of quartz (sio2) to yield a glass of composition 75 wt% sio2, 15 wt% na2o, and 10 wt% cao.

answer: 500 wph.

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
