Consider the heating curve. A graph of temperature versus time, with time in minutes as the horizontal axis and temperature in degrees Celsius as the vertical axis. 5 sections of line are labeled: 1 from 0 minutes, negative 50 degrees to 1, 0 degrees. 2: from 1, 0 to 5, 0. 3: from 5, 0 to 9, 2200. 4: from 9, 2200 to 17, 2200. 5: from 17.0, 2200 to off the chart at 2,400 degrees.
In which region are most particles moving the fastest?

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]

Draw a line graph showing the relationship between temperature in kelvin as a function of kinetic energy.

Some familiar products contain some of the same types of atoms. for instance, the chemical formula for baking soda is nahco 3. the chemical formula for liquid bleach is naclo, and the chemical formula for table salt is nacl. which choice best describes why these three products have some of the same types of atoms in common?
