Answer: 26.25 miles per gallon
Explanation: first odometer reading = 65290
Second odometer reading = 65500
Difference in odometer reading = second reading - first reading
= 65500 - 65290 = 210 miles.
If it took 8 gallons to fill his tank, it means
8 gallons will get him 210 miles, therefore 1 gallon will get 210 miles/8gallons = 26.25miles/gallon. Hence he is getting 26.25miles/gallon.
B
Meniscusity the convex or concave upper surface of a column liquid, the curvature of which is caused by surface tension
Answer:Well-known examples are sodium hydroxide (NaOH) with OH- as the polyatomic anion, calcium carbonate (CaCO3), and ammonium nitrate (NH4NO3), which contains two polyatomic ions: NH+ and NO3-. ... The properties of compounds containing polyatomic ions are very similar to those of binary ionic compounds.
Explanation:
Actually Rb or Rubidium in zero state has the following
electron configuration:
<span>1s22s2</span><span>2p6</span><span>3s2</span><span>3p63d10</span><span>4s2</span><span>4p65s1</span>
However we can see that the ion has a 1 positive charge,
which means that it lacks 1 electron, therefore the answer from the choices is:
<span>d.
rb+: 1s22s22p63s23p64s23d104p6</span>
NOOOO NO thats not true at all
<span>Esters can be shown in text as: RCOOR or (occasionally) ROCOR.</span>
