The answer to your question is C. A solution is a homogeneous mixture composed of two or more substances, so it couldn't have been A and D. Since a solution can't have its substances separated by a chemical means because they are chemically bonded, thus they are able to be separated by physical means
2C2H2(l) +5O2(g)→ 4Co2(g) + 2H2O
The limiting reactant for reaction above is O2
<u><em>explanation</em></u>
The limiting reagent is determined using mole ratio of both reactant.
that is the mole ratio of C2H2:O2 which is 2:5 .
The mole ratio above implies that 37.0 mole of C2H2 needs 37.0 moles x5/2=92 moles of O2.
<em>Since the available moles of O2 was 81.0 mole and 92 moles are required to completely react with C2H2</em><em> ,</em> <u>O2 is the limiting reagent.</u>
Answer:
1. Is red blood cells
2. Is high pressure
Explanation:
In the atrium deoxygenated blood is pumped
A = change in velocity / time
so change in velocity = 13-7 = 6
so 6/1 =6:
acceleration = 6m/s^2
Answer:
Approx. 20 moles of iron.
Explanation:
There are approx. 6.022 x 10.23 iron atoms per mole of iron. In this quantity, The number of iron atoms has a mass of
55.85 ⋅ g.
