You used a calorimeter in the heat transfer lab. Explain how the calorimeter works, and how to calculate the heat given off or a
Olenka [21]
A calorimeter contains reactants and a substance to absorb the heat absorbed. The initial temperature (before the reaction) of the heat absorbent is measured and then the final temperature (after the reaction) is also measured. The absorbent's specific heat capacity and mass are also known. Given all of this data, the equation:
Q = mcΔT 
To find the heat released.

Compare the forces of attraction between molecules in water, sugar and oxygen. Rank them in order from greatest to least. A) wat
VladimirAG [237]

Answer:

Option C, sugar, water, oxygen

Explanation:

Force of attraction leads to closer placing of atomic particles in any element or molecule. The higher the force of attraction, the more compact is the arrangement of the atomic particle.

Thus, in a solid the atomic particles are closely packed followed by a liquid and then a gas.

As we know sugar is solid, water is liquid and oxygen is gas.

Thus, forces of attraction between molecules of sugar will be the highest followed by water and then oxygen

Hence, option C is correct

The volume of a single rhodium atom is 1.01×10-23 cm3. What is the volume of a rhodium atom in microliters?
Anni [7]

Answer: 1.01 x 10^20 microliters.

Explanation: volume is defined as a three-dimensional measure of space that comprises a length, a width and a height. In other words, we are asked to convert from one volumetric measure to another (cubic centimeters to microliters) —volume is measured in units of cubic centimeters in metric, cubic inches or cubic feet in English measurement.

If, 1 cm³ = 1000 uL (microliters) then,

1 uL - - - - - - - - - 0.001 cm³ = 1 x 10^-3 cm

x uL - - - - - - - - - 1.01×10^-23 cm³

Therefore,

x uL = 1.01 x 10^-23 cm³ / 0.001 cm³

x uL = 1.01 x 10^(-23 - - 3)

x uL = 1.01 x 10^( - 23 + 3)

x uL = 1.01 x 10^20

Which is to say that a single rhodium atom of volume 1.01 x 10^23 cm³ would occupy 1.01 x 10^20 microliters.
