The circulatory system has 4 chambers - 2 Atria and 2 ventricles.
2 Atria - the left atrium receives blood from the pulmonary (lung) circulation, and the right atrium receives blood from the venae cavae (venous circulation). The atria receive blood while relaxed (diastole), then contract (systole) to move blood to the ventricles.

2 Ventricles - two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta.

5f2 (g) + 2nh3 (g) → n2f4 (g) + 6hf (g) if you have 58.5g nh3, how many grams of f2 are required for a complete reaction? how ma
xxTIMURxx [149]
5F2 +2NH3 = N2f4 + 6HF

moles = mass/molar mass
mass =molar mass x mole

a)   moles of Nh3 = 58.5/17 = 3.44 moles
the mole  ratio of F2:NH3 = 5:2
the moles of F2 =3.44x5/2=8.6 moles
mass= 8.6 x 38 = 326.8 grams  of F2

B) moles of Hf = 3.89/20 = 0.1945 moles
mole ratio NH3:Hf =  2:6
moles of  NH3 = 0.1945 x2/6 = 0.0648 moles
mass =0.0648 x17 = 1.102 grams of NH3

C) moles of f2 = 217/38 =5.711 moles
mole ratio N2F6:F2 = 5:1
moles of N2F4 =5.711 x1/5 =1.142 moles
mass = 1.142 x104 = 118.77 grams of N2F4
