Answer:
without being wordy, CARBON makes Only 4 and Always 4 bonds. If you want to count electrons & so on, go ahead, but in the end the
Primary Rule In Organic Chemistry is
Carbon makes 4 bonds. Check the OCTET RULE and so on to see if that gives you insight as to why, and a more complete answer. OK?
Explanation:
Answer:
For 6.50 mol NaOH - 1.44M.
For 6.50 g NaOH - C. 0.0361 M
Explanation:
For 6.50 mol NaOH.
Molarity = moles solute/L solution = 6.5 mol/4.5 L solution = 1.44 mol/L=1.44M
There is no such answer in given choices.
For 6.50 g NaOH
M(NaOH) = 23 + 16 + 1 = 40 g/mol
Molarity = 6.5g* 1 mol/40g *1/4.5L = 0.0361 mol/L = 0.0361 M
There is such answer. It is C.
If they need 4 people to a pulley then they would need a 8 to two pulleys
here is the equation
4people*2/pulley*2
8people/2pulley
