Consider the reaction for the combustion of octane (C8H18). 2C8H18 + 25O2 = 16CO2 + 18H2O
A. How many moles of H2O are produced when 0.281mol of octane is burned?
B. How many moles of CO2 are produced when 8.12mol of oxygen reacts with octane?

no but i do not usually comment or use my voice that much when it comes to social media

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
