Answer: I think the answer is 1
i just learned this about two weeks ago
Explanation:
Answer:
Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)
Explanation:
I took this quiz and the correct answer is not A.
4Na3PO4 The 4 at the beginning of the formula is important, it means you multiply everything after it by 4 so you would instead get the answer,
D. 12 Sodium, 4 phosphorus, 16 oxygen
Answer:
2.20 x 10²⁵ atoms
Explanation:
Atoms of CO= 36.6-mol sample
From Avogadro's constant, which is
(6.022 × 10^ 23 atoms per mole)
Then
Number of atoms=[ 6.022 × 10^ 23 atoms/mole] × [36.6-mol]
= 2.20 x 10²⁵ atoms
Hence, number of atom is 2.20 x 10²⁵ atoms
V₁-?
v₂-?
v₃=360 mL
w₁=0.06
w₂=0.14
w₃=0.11
v₁+v₂=v₃
v₁w₁+v₂w₂=v₃w₃
We substitute figures and we solve system of two equations in two unknowns.
v₁=135 mL (6%)
v₂=225 mL (14%)
