Answer:
A.
Explanation:
Power is measured in Watts, and can we calculated by taking the work done in joules / the time in seconds. Thus, 1 Watt is 1 joule per 1 second (1 Watt = 1J/s)
Answer:
The density of Lithium β is 0.5798 g/cm³
Explanation:
For a face centered cubic (FCC) structure, there are total number of 4 atoms in the unit cell.
we need to calculate the mass of these atoms because density is mass per unit volume.
Atomic mass of Lithium is 6.94 g/mol
Then we calculate the mass of four atoms;
⇒next, we estimate the volume of the unit cell in cubic centimeter
given the edge length or lattice constant a = 0.43nm
a = 0.43nm = 0.43 X 10⁻⁹ m = 0.43 X 10⁻⁹ X 10² cm = 4.3 X 10⁻⁸cm
Volume of the unit cell = a³ = (4.3 X 10⁻⁸cm)³ = 7.9507 X 10⁻²³ cm³
⇒Finally, we calculate the density of Lithium β
Density = mass/volume
Density = (4.6097 X 10⁻²³ g)/(7.9507 X 10⁻²³ cm³)
Density = 0.5798 g/cm³
The reaction equation given is already balanced. So the ratio of the reactants and products is the same as the ratio of coefficients. Then the answer is 4 moles.
The number of bacon double cheeseburgers that can be made starting with the given ingredients is; five.
<h3>What are Limiting Reactants?</h3>
Limiting reactant(s) as the name implies are reactants whose availability is limited and hence, the the rate at which products are formed is limited subsequently.
From the question, to determine the limiting Reactant;
- We must divide the available quantity of each Reactant by the required quantity for the production of one unit cheeseburgers.
Hence;
- 12 buns/1 = 12 cheeseburgers.
- 20 patties/2 = 10 cheeseburgers
- 24 slices of cheese/2 = 12 cheeseburgers
- 20 strips of bacon/4 = 5 cheeseburgers.
On this note, the limiting Reactant is strips of bacon and hence, the number bacon double cheeseburgers that can be made starting with the given ingredients is; five.
