What volume of 0.0955 M HCI in millimeters is required to titrate 2.152 g of Na2CO3 to the equivalent point/ My teacher does not explain any thing and I need to understand this.
The rate of decomposition of C3H6 in the following reaction is 0.45 M/s. Calculate the rate of production of H2O. 2 C3H6 + 2 NH3 + 3 O2 → 2 CH2CHCN + 6 H2O
To what temperature must a substance be heated so that its thermal energy is about 9 kJ/mol? Express your answer to the nearest degree.
The method used in this experiment is sometimes called the vapor density method. Beginning with ideal gas equation, show how the density of a vapor may be determined by this method.
2.00 x10^2 mL of .744 M HCl is mixed with 2.00 x 10^2 mL of .372 M Ba(OH)2. how many moles of water are produced in the reaction
CaC2 (s) + 2H2O (l) → C2H2 (g) + Ca(OH)2 (aq) If 32.0 g CaC2 are consumed in this reaction, how many moles of H2O are needed?
Into what type of unit cell (i.e., simple cubic, face-centered cubic, or body-centered cubic) does this material crystallize? Be sure to fully support your answer. The apparent atomic mass is 120.5 amu. Remember that 1 amu = 1.660538783 × 10!24 g.
explain in molecular terms, whether evaporation rate of a liquid is constant or varied in the presence of changing ambient air pressure.
khc8h4o4 aq naoh aq -gt nakc8h4o4 aq h2o la. naoh is approximately 0.1 m. each titration will use 25.00 ml of khp
If sample of sodium is dropped into a container of water the reaction is 2Na +2H2O ---> 2NaOH +H2. If 10.4 g of hydrogen are produced, how many g of NaOH are also formed
A sample of gas has a temperature of 0 celsius and a volume of 453 m. At constant pressure, the temperature is raised to 100Celsius. What is the new volume
A 0.75 L bottle is cleaned, dried, and closed in a room where the air is 22 degree Celsius and 44% relative humidity (that is, the water vapor in the air is 0.44 of the equilibrium vapor pressure at 22 degree Celsius). The bottle is brought outsid..
What is the change in internal energy (in J) of a system that absorbs 0.535 kJ of heat from its surroundings and has 0.362 kcal of work done on it
