They are both made up of the same protein called "histones".
Answer:
1s2 2s2 2p6 3s2 3p6
Explanation:
Calcium is the 20th element. It has 20 electrons in it's neutral state. The electronic configuration is given as;
1s2 2s2 2p6 3s2 3p6 4s2
However in the compound; calcium chloride, it does not exist in it's neutral state.
CaCl2 --> Ca2+ + Cl-
In Ca2+ state, it has lost two electrons, The total number of electrons becomes; 20 - 2 = 18 electrons.
The electronic configuration is given as;
1s2 2s2 2p6 3s2 3p6
Answer:
b and d hope this helped
Explanation:
turtles don't have gills and neither does owls so anything
without gills
Speed is equivalent to the distance traveled divided by the time it takes to travel that certain distance.
To solve this problem convert the units first from meter and yards to miles. 100 metes is 0.0621371mi and 100 yards is 0.0568182 yard. 9.69s = 0.002691667 hr and 9.21s = 0.002558333
A.) 23mi/hr
B.) 22.20mi/hr
1 CH4 (g) + 2 O2 (g) -----> CO2 (g) + 2H2O(l) ΔH= - 890 kJ
1 mol 2 mol
1) If ΔH has minus, it means "release". We need only "release" choices.<span>
2) From reaction
1 mol </span>CH4 (g) "releases" ΔH= - 890 kJ - We do not have this choice.
2 mol O2 (g) "release" ΔH= - 890 kJ, so
1 mol O2 (g) "release" ΔH= - 445 kJ
Correct answer is B.
