In response to Boyle’s Law, the pressure of a gas increases as the volume decreases because
kondaur [170]

Answer:

the gas particles strike the walls of the container more often

Explanation:

Following Boyle's law, if the amount of gas and the temperature remain constant, the product of the pressure for the volume remains constant, but when altering any of these conditions this value changes and is expressed through the equation:

<em>                                                       </em>P_{1} V_{1}  = P_{2}V_{2}<em></em>

So, when the volume decreases, the distance that the particles have to travel is smaller and therefore more collisions between particles and between the walls occur per unit of time, that is, the system pressure increases.

Hydrogen gas, H2, reacts explosively with gaseous chlorine, Cl2, to form hydrogen chloride, HCl(g). What is the enthalpy change
Degger [83]

Answer:

-184.6 KJ/mole

Explanation:

H2(g) + Cl2(g) ------------> 2HCl(aq)    

Δ H0 rxn = Δ H0f products - Δ H0f reactants

= 2×-92.3 - (0 + 0)

= -184.6KJ/mole

H2(g) + Cl2(g) ------------> 2HCl(aq)       Δ H0rxn   = -184.6KJ/mole

Why is water essential to living things? (1 pc
DIA [1.3K]

Answer:

Living organisms need water to survive. Many scientists even believe that if any extra-terrestrial exists, water must be present in their environments. All oxygen-dependent organisms need water to aid in the respiration process. Some organisms, such as fish, can only breathe in water. Other organisms require water to break down food molecules or generate energy during the respiration process. Water also helps many organisms regulate metabolism and dissolves compounds going into or out of the body.
