The lymphatic system is part of the circulatory system and a vital part
of the immune system, comprising a network of lymphatic vessels that
carry a clear fluid called lymph directionally towards the heart. i believe is the answer
<em>Answer:</em>
- The molarity of ammonia will be 2.88 M.
<em>Chemical equation</em>
HCl + NH3 ------> NH4Cl
First of calculate the moles of HCl
mole of HCl = Molarity × Vol (L)
mole of HCl = 0.800× 0.018 = 0.014 mole
As the in balance chemical, moles of HCl and NH3 areequal
so
moles of NH3= 0.014
Molarity of NH3 = moles ÷ V(L) = 0.014/0.005 = 2.88 M
<em>Result</em>:
- The molarity of ammonia will be 2.88 M.
The reaction between iron and nitric acid eventually produces a red-brown rust colour (iron(III) oxide). could link this with corrosion and acid rain
We combine the two equations, like we would any mathematical system of equations. After addition of the two equations, we get:
Mg + 2H⁺(aq) + 2e⁻ → Mg⁺²(aq) + H₂(g) + 2e⁻
Cancelling like terms from both sides
Mg + 2H⁺(aq) → Mg⁺²(aq) + H₂(g)
Answer:
Q = 4.056 J
Explanation:
∴ m = 406.0 mg = 0.406 g
∴ <em>C </em>= 1.85 J/g.K
∴ T1 = 33.5°C ≅ 306.5 K
∴ T2 = 38.9°C = 311.9 K
⇒ ΔT = 311.9 - 306.5 = 5.4 K
⇒ Q = (0.406 g)(1.85 J/gK)(5.4 K)
⇒ Q = 4.056 J
