why does a can of soda explode in a hot car?
As the temperature rises, the gas (carbon dioxide that make the fizzle in soda pop)exerts more and more pressure until the container ruptures. Any gas heated tries to expand due to greater molecular motion.If it is contained, it exerts more pressure on the container. The same thing happens to a balloon in the sun.
thanks
I have to balance the following equation using the lowest number of coefficients
CH4 + NH3 + O2 -- HCN + H2O
I can get N,C and O to balance as follows
CH4 + NH3 + O2 -- HCN +2H2O
I can get H,C and N to balance as follows
CH4 + NH3 2O2 -- HCN + 3H20
Can anyone help me as I just can't seem to get all four to balance and I'm not sure where I'm going wrong
To balance the given chemical equation, CH4 + NH3 + O2 -> HCN + H2O, follow these steps:
Step 1: Start with the element that appears in the fewest number of compounds. In this case, it is nitrogen (N).
Step 2: Balance the nitrogen (N) atoms by placing a coefficient in front of NH3 and HCN. Since there are three nitrogen atoms in NH3 and only one in HCN, place a coefficient of 3 in front of NH3 and 1 in front of HCN:
CH4 + 3NH3 + O2 -> HCN + H2O
Step 3: Move on to the next element, carbon (C). Balance the carbon atoms by placing a coefficient in front of CH4. There is one carbon atom in CH4 and only one in HCN, so place a coefficient of 1 in front of CH4:
1CH4 + 3NH3 + O2 -> HCN + H2O
Step 4: Now, consider hydrogen (H). Balance the hydrogen atoms by placing a coefficient in front of H2O. There are four hydrogen atoms in H2O and only one in NH3, so place a coefficient of 4 in front of H2O:
1CH4 + 3NH3 + O2 -> HCN + 4H2O
Step 5: Finally, balance the oxygen (O) atoms. Start with the O2 molecule on the left side. Count the oxygen atoms: there are 2 oxygen atoms in O2. To balance this, place a coefficient of 2 in front of O2:
1CH4 + 3NH3 + 2O2 -> HCN + 4H2O
Now, all the elements are balanced, resulting in the balanced equation:
1CH4 + 3NH3 + 2O2 -> 1HCN + 4H2O.
