The structures and chemistry of individual hydrocarbons depend a large part on the types of chemical bonds that link together the atoms of their constituent molecules. Hydrocarbons are derived by chemical degradation.
The nervous system sends signals to the muscles to shiver when our body temperature begins to drop to a lower than normal temperature. the slight movement of the muscles will work to bring temperature back to homeostasis
Answer:
2s
Explanation:
Given parameters:
Acceleration of the truck = 15m/s²
change in Velocity = 30m/s
Unknown:
Time taken for the body to slow down = ?
Solution:
Acceleration is the rate of change of velocity ;
Acceleration = 
time = 
Now insert the parameters and solve;
time = 
= 2s
Answer:
Calcium is in the 4th period and 2nd group
If I understand the question correctly, I think the answer is true. My reasoning is that each formula for the molecules used in a reaction are set and can't be modified to make it easier to balance or else the reaction would change fundamentally.
an example of this is H₂+1/2O₂⇒H₂O. You can't change the H₂O to H₂O₂ to make the reaction cleaner. Water and hydrogen peroxide are two different chemicals and therefore can't be interchanged with out changing the fundamental qualities of the reaction
