2.3 moles of helium gas is at a pressure of 1.70 atm and the temperature is 41 °C. What is the volume of the gas?

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst

The density of the solid phase of a substance is 0.90 g/cm3 and the density of the liquid phase is 1.0 g/cm3. a large increase in pressure will a. lower the freezing point b. raise the freezing point c. lower the boiling point d. raise the triple point e. lower the triple point

+= + + balance the equation on coefficients, ex. 1,1,1
