Answer:
7000 kg*m/s E
Explanation:
Momentum formula: p=mv
m=200kg
v=35 m/s East
p=(200kg)(35m/s E)
m=7000 kg*m/s E
If you want to simplify it further, m=7*10^3 kg*m/s E
Answer:
the answer is d when the state of matter changes it's not a chem change
Answer:
It released hydroxide ions (OH ¯).
Explanation:
A PH of 8.3 indicates that the solution has become a basic solution.
Now, for us to have a basic solution from the addition of an alka-seltzer to Koolaid, it means the Alka-seltzer released plenty of hydroxide ons (OH¯) to the solution.
Answer:
It is an saturated compound since there are no c-c double or tripple bonds.
Explanation:
If we had such double or tripple bonds the remaining o &H atoms cannot be accommodated to the carbon chain.
the carbon skeleton has (26×2)+6=58 valence electrons
O occupies 2 for each
18×2= 36
,58-36=22
only 22H can be directly bonded to the carbon skeleton.
remaining H= 14
therefore 7carbonyl carbon atoms will have to turn into carbinol carbon atoms .
so no space for c-c double bonds
