Is there a pic and a TRANSLATION is when you move a from one place to another with it remaining congruent. Hop that helps....
NO, 16:14 and 64:60 does not equal
16:14 = 1.1428
64:60 = 1.0666
hope this helps
Answer: 1 .214 2.455 3.455 4. 343
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
<span> Molecules comprised of main group elements adopt the structure that minimizes the repulsions between bond pairs (bp) of e⁻s and lone pairs (lp) of e⁻s (VSEPR theory: Wikipedia). However lp are only attracted to one +ve nucleus and consequently are more diffuse (spread out) and hence in terms of e⁻↔ e⁻ repulsion: lp-lp>lp-bp>bp-bp. So we have: CH4 AX4 regular tetrahedron angles all 109.5°; NH3 trigonal pyramidal AX3E the lone pair squeezes the H-N-H angles to <109.5° (~108°); for H2O: AX2E2 V shaped or bent - now we have lp-lp repulsion the H-O-H closes to significantly less than 109.5° (~104°).
