4. A block of lead (mass = 30 g) at 90.0°C is dropped into water at 20.0°C in a well-insulated coffee cup calorimeter. The final temperature of the system is 21.6°C. What volume of water was in the
calorimeter?

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
