VOLUME= 5cm*10cm*2cm =100cm^3
but density of iron=7.874g/cm^3
mass=7.874g*100 =787.4g
mass of that block = 787.4g

Answer : 787.4 g

Explanation : With the given information; the volume of the block will be equal to = 5 cm X 10 cm X 2 cm = 100 cm^{3}.

Therefore, the volume will be 100 cm^{3}.

but density of iron is found to be 7.874 g/cm^{3}

So, now calculating for mass; on the basis of the density formula;

which is density = mass/volume; so, mass = density X volume;

Therefore, mass will be 7.874 g X 100 = 787.4 g

mass of the iron block = 787.4 g

Describe how the mass of the product can be calculated when one reactant is in excess
kvasek [131]
On the off chance that one of the reactants is in overabundance yet you don't know which one it is, you have to compute the hypothetical item mass for the both reactants, with a similar item, and whichever has the lower yield is the one you use to precisely depict masses/sums for the condition, since you can't have more than the non-abundance reactant can create.

Calculate the food energy (joules/
Anna007 [38]

Calculate the food energy (joules/g) of one of your food samples. one chemistry calorie is equal to 4.186 joules. convert the energy you calculated to kilojoules (1 kj = 1000 j). since nothing is given, an example is avocadoes have 160 cal/100 g serving

(160 cal/ 100 g)(4.186 J/ 1 cal) (1 kJ/1000 J) = 0.0067 kJ/g

How does the surface metabolism model of chemical evolution differ from the prebiotic soup model? see section 2.4 ( page 70) ?
evablogger [386]

The surface metabolism model evokes mineral catalysts. Surface metabolism model dissolved gases in contact with minerals lining the walls of the deep-sea hydrothermal vents and formed more complex, organic molecules while Prebiotic soup model is molecules in atmosphere or from meteorites condensed in the ocean which led to the formation of more complex molecules.
