Answer: C3H8 + 5O2 = 3CO2 + 4H2O
Explanation:
1. First start by writing out the unbalanced equation
2. Count all the atoms on both sides of the equation
C = 3 C =1
H = 8 O=3
O = 2 H =1
3. Start by balancing the carbon atoms. What would it take to have 3 Carbon atoms on the left? You would add a 3 in front of the carbon atoms on the left side to match the carbon atoms on the right.
4. Now Try balancing the H atoms. You have 8 H atoms on the right and 1 H atom on the left. To balance these out you would need to add a 4 in front of the H atom which gives you 8 on both sides.
5. Now balance out the oxygen atoms. Since we added coefficients to the compounds on the left we now have 10 oxygen on the left 4x1=4 + 3x2=6 now balance out the right side of the equation by adding a 5 in front of the O2 5x2 Oxygen gives you 10.

<h2>Answer:</h2>
Justin Bleeber noticed almost 4 chemical changes while conducting his experiment with a soda can. He noticed chemical changes in cracker burns when it heats the water in a soda can. He observed the chemical change when the waves of the gas are seen coming out on the top of the can. He also observes changes while he uses the flame from Bunsen burner to light a wooden split.
Answer:
D. 2.5 x 10 ^-14 Hz
Explanation:
Use wavelength formula: v = f x wavelength
Rearrange formula for frequency.
f = wavelength / v
f = 7.6 x 10 ^-6 / 3.00 x 10 ^8
f = 2.5 x 10^-14 Hz
