2 tablets every 6 hours. The patient will receive four doses of 2 tablets. The physician will need 8 tablets for one days treatment.
Answer:
a) Q=19600W b)Q=60W
Explanation:
q=k.(T₀-T₁)/x
a)
T₀=inside temperature (K)= 273+15=288K
T₁=outside temperature(K)= 273-20=253K
x=5x10⁻³m
k=1.4W/m.K
∴q=9800W/m² ⇒ Q=q.Surface
Q=9800W/m² . 1m . 2m = 19600W.
b)
T₀=inside temperature (K)= 273+10=273K
T₁=outside temperature(K)= 273-15=258K
x=10x10⁻³m
k=0.024W/m.K
∴q=60W/m² ⇒ Q=q.Surface
Q=60W/m² . 1m . 2m = 120W.
Answer:
[NaCl] = 1.72 M
Explanation:
First of all, we balance the equation:
BaCl₂ + Na₂SO₄ → 2NaCl + BaSO₄
We convert mass of barium chloride to moles
45 g . 1mol / 208.23g = 0.216 moles
Ratio is 1:2. This means, that our moles of reactant may produce the double of moles, of product.
0.216 . 2 = 0.432 moles of NaCl are been produced.
Molarity is mol/L. We convert volume of water from mL to L
250 mL . 1L /1000 mL = 0.250 L
[NaCl] = 0.432 mol/0.250L = 1.72 M
Answer:
B. organ
Explanation:
Smooth muscle is found in the walls of hollow <u>organs</u> like your intestines and stomach. They work automatically without you being aware of them. Smooth muscles are involved in many 'housekeeping' functions of the body.
