Answer:
CuCl2 + H2S -> CuS + 2HCl
Explanation:
in the reactants the 2 in 2HCl multiplies to give you 2 Hydrogens and 2 Chlorides.

Here Are Some Tanning Bed Tips For Beginners To Help You Get The Most .Knowing your skin type before you tan can help you to do so safely and help . If you want to ensure you get a quality tan, you first need to be certain your . Obviously, if you wear a bathing suit, you'll get tan lines from the suit. Apply indoor tanning lotion evenly in a circular motion and over all areas of the body. Using the right skin care products is the best way to extend the life of your tan. Note that lotions not made for indoor tanning can cause damage to tanning beds and don't help develop your tan. So what (if anything) should you wear? There are a lot of different views on this particular question, and it all comes down to one very simple answer: wear whatever you are comfortable in. If you wear your bathing suit every time, you will have tan lines that reflect that, but that's your choice.

Answer:
a) 43.2 Jm⁻³
b) 0.0941 J
Explanation:
A = area of cross-section = 23 cm² = 23 x 10⁻⁴ m²
l = length of solenoid = 94.9 cm = 0.949 m
L = inductance of solenoid
N = Number of turns = 809
i = current = 9.70 A
Inductance is given as
L = μ₀ N² A l⁻¹
L = (12.56 x 10⁻⁷) (809)² (23 x 10⁻⁴) (0.949)⁻¹
L = 0.002
V = Volume = Al = (23 x 10⁻⁴) (0.949) = 21.8 x 10⁻⁴ m³
Energy density is given as
U = (0.5) L i² V⁻¹
U = (0.5) (0.002) (9.70)² (21.8 x 10⁻⁴)⁻¹
U = 43.2 Jm⁻³
b)
Total energy is given as
E = (0.5) L i²
E = (0.5) (0.002) (9.70)²
E = 0.0941 J
