Explanation:
Most of our data are based on published information from the Association of American Medical Colleges, the Educational Council for Foreign Medical Graduates, the American Board of Medical Specialties, and the National Resident Matching Program. Data on board-certified physicians were obtained from the Division of Survey and Data Resources of the American Medical Association and are not published elsewhere
i think thats right
Answer:
Principle quantum number.
Explanation:
I believe a solution of Sn(NO3)2 can not be stored in an aluminium container because Aluminium is higher in the reactivity series compared to Tin (Sn). Therefore, Aluminium is more reactive than Tin and hence aluminium will displace Tin from its salt forming Aluminium nitrate and Tin metal. Thus storing Tin nitrate in an aluminium container will cause the "eating away' of the container.
Answer:
1.The Aluminum block
2.its surroundings absorb energy from it.
Explanation:
In this question it is important to remember that density of an object is the mass of that object divided by its volume.
The expression applied here is density=mass/volume
Given that the mass is constant,lets say mass= m=1g
and density of aluminum=2.7g/cm³ and that of iron is 7.8 g/cm³ then volume=?
Volume=mass/density
Volume of aluminum= 1/2.7 =0.3704 cm³
Volume of iron = 1/7.8 =0.1282 cm³
Here we see volume of Aluminum block is the largest.
2.As water in an ice cube tray freezes, its surroundings absorb energy from it.When the water freezes, latent heat of freezing is given out to the surrounding.When water is freezing, it stays at a constant temperature of 0°C, the heat energy released ensures that there is no cooling past 0 °C.
