The penguin has a sleek body that helps it to move quickly in water.
Answer: 0.075
Explanation:
(concentration in molarity)(volume in liter) = answer
0.15 mol/L *0.500L = 0.075 mol
Answer:
B) Symmetrical and nonpolar
Step-by-step explanation:
The formula is H-C≡C-H.
Each C atom has <em>two</em> electron regions, so VSEPR theory predicts a <em>linear molecular geometry</em> (see image below).
The molecule is symmetrical, because the green line divides the molecule into two halves that are mirror images of each other.
The C-H bonds are slightly polar, because C is more electronegative than H (µ ≈ 0.4 D).
The C atoms are partially negative (red), while the H atoms are partially positive (blue).
However, the two C-H bond dipoles point in <em>opposite directions</em>, so they cancel each other. The molecule has <em>no net dipole moment.</em>
Acetylene is nonpolar.
His strict imposition of autocratic rule was supported by his appointment by the King, who otherwise was not directly involved.
Explanation:
Andros’ imposition of Episcopalian worship in the Old South Meeting house, Boston his vigorous enforcement of the Navigation Acts.
He had earned the enmity of the local populace by enforcing the restrictive Navigation Acts.
He had infuriated Puritans in Boston by promoting the Church of England, which was rejected by many Nonconformist New England colonists.
When news of the overthrow of James II (1688) reached Boston, the colonists revolted, deposing Andros and imprisoning him.
His requirement that landholders take out new land patents and his limitations upon town meetings and rights of local taxation all aroused sharp resentment in colonial America.
