Answer is B because C and D make has nothing to do with the question and A isn’t it
Answer:
Option (C)
Explanation:
Atoms are the basic structures that are combined to form minerals, which are further accumulated giving rise to the formation of rocks. These atoms plays a significant role in the formation of rock and their significant characteristics.
When atoms are passed through the rock cycle, they are not able to move at the same rate, but they can move at a different rate. When a rock changes from one kind to another, its constituent minerals and atoms also alters, forming a different rock type with variable characteristics and properties.
Thus, the correct answer is option (C).
Answer:
the answer is D the dominant over powers the resecive traits
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>
