Answer:
A major characteristic of mixtures is that the materials do not chemically combine
Explanation:
Mixtures can be divided into those that are evenly distributed (homogeneous) and those that aren't (heterogeneous)
Barium Cynanide is the compound
Answer:
The answer is 1, 2, 3 for the first question and 1,2,3 again for the second question.
Explanation:
The true statements about complex IV are:
1) This complex catalyzes the reduction of oxygen to water.
2) Despite consuming protons, this complex pumps H+ across the membrane at a rate of 4 per molecule of O2 reduced.
3) The protons flow across a gradient to the inner membrane space.

Answer:
237.2 mL.
Explanation:
- We have the rule: at neutralization, the no. of millimoles of acid is equal to the no. of millimoles of the base.
(XMV) acid = (XMV) base.
where, X is the no. of (H) or (OH) reproducible in acid or base, respectively.
M is the molarity of the acid or base.
V is the volume of the acid or base.
<em>(XMV) HCl = (XMV) NaOH.</em>
<em></em>
For HCl; X = 1, M = 0.5 M, V = ??? mL.
For NaOH, X = 1, M = 1.54 M, V = 77.0 mL.
<em>∴ V of HCl = (XMV) NaOH / (XV) HCl = (</em>1)(1.54 M)(77.0 mL) / (1)(0.5 M) = <em>237.2 mL.</em>
