I'm pretty sure hydrogen is but i would go with #3 carbon
Answer:
Like your refrigerator, heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. ... The most common type of heat pump is the air-source heat pump, which transfers heat between your house and the outside air.

Hmm trick question here's my answer: the content: protons charge the electrons into its usage , the size: 1.6fm if I'm wrong sorry if I'm right: HA IN YOUR FACE HA!!!
Answer:
See explanation
Explanation:
2HCl(aq) + CaCO3(aq) ------->CaCl2(aq) + CO2(g) + H2O(l)
Number of moles of acid present = 50/1000 * 0.15 = 0.0075 moles
Number of moles of calcium carbonate = 0.054g/100 g/mol = 0.00054 moles
2 moles of HCl reacts with 1 mole of calcium carbonate
x moles of HCl reacts with 0.00054 moles of calcium carbonate
x = 2 * 0.00054/1
x = 0.00108 moles of HCl
Amount of acid left = 0.0075 moles - 0.0075 moles = 0.00642 moles
Reaction of HCl and NaOH
HCl(aq) + NaOH(aq) ------> NaCl(aq) + H2O(l)
Since the reaction is in the mole ratio of 1:1
0.00642 moles of HCl is neutralized by 0.00642 moles of NaOH
Answer:
Two possible compounds are shown below- one with an exocyclic double bond and another one with an endocyclic double bond
Explanation:
Reaction of alkene with
gives a complex of mercurous ion.
Then water molecule attacks this complex through
type reaction at more substituted position.
cleaves the resultant C-Hg bond and forms a C-H bond.
Two possible structures of an alkene is possible to yield 1-methylcyclohexanol which are shown below.
