A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.6336 g sample of nonanedioic acid (C9H16O4) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.236×103 g of water. During the combustion the temperature increases from 26.86 to 29.59 °C. The heat capacity of water is 4.184 J g-1°C-1.

The heat capacity of the calorimeter was determined in a previous experiment to be 980.4 J/°C.

Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of nonanedioic acid based on these data.

C9H16O4(s) + 11O2(g) 8 H2O(l) + 9 CO2(g) + Energy

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

catya your not at all which answer i've seen you do this on another question!

im doing test rn im going with 2 but ill give answer if itss wrong,   : )
