Use the periodic table to select which type of bond is present and which of the listed properties is most likely for each substance. A = B = A 3-column table with 2 rows. Column 1 is labeled substance with entries upper C 8 upper H 18, and upper K 2 upper O. Column 2 is labeled Type of Bond with entries A and C. Column 3 is labeled Likely Property with entries B and D.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

the answer is b & c i believe : )

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
