A 50.00 g sample of an unknown metal is heated
to 45.00°C. It is then placed in a coffee-cup
calorimeter filled with water. The calorimeter and
the water have a combined mass of 250.0 g and
an overall specific heat of 1.035 cal/g.°C. The
initial temperature of the calorimeter is 10.00°C.
The system reaches a final temperature of 11.08°C
when the metal is added. what is the specific heat?

The image shows a process that releases nuclear energy which statement best identifies the process shown the process must be fusion because energy is released the process must be fusion because of have your nucleus formed a smaller nuclei the process must be fission because a large nucleus breaks into smaller nuclei the process must be fission because neutrons are formed

The chart shows the bid provided by four contractors to complete a job. which contractor is the most cost-effective?

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.
