Answer:
50.3mL of mercury are in 1.50lb
Explanation:
Punds are an unit of mass. To convert mass to volume we must use density (13.546g/mL). Now, As you can see, density is in grams but the mass of mercury is in pounds. That means we need first, to convert pounds to grams to use density and obtain volume of mercury.
<em>Mass mercury in grams:</em>
1.50lb * (1kg / 2.20lb) = 0.682kg = 682g of mercury.
<em>Volume of mercury:</em>
682g Mercury * (1mL / 13.546g) =
<h3>50.3mL of mercury are in 1.50lb</h3>
Answer:
d. n = 4, l = 2, m = 0
Explanation:
A d-orbital in the fourth energy level can only be represented by n = 4, l = 2, m = 0.
n is the principal quantum number(n) which signifies the energy level, here it is 4;
l is the azimuthal quantum number or l which signifies the shape of the subshell, it takes a value of n - 1, 0,1,2 or 3
m is the magnetic quantum number(m) which can be -2, -1, 0, 1 , 2
So, the right and fitting solution is n = 4, l = 2, m = 0
Light bulb -it produces heat and light
toaster - it produces heat and the metal strips glow producing light
