What if it is something like 0 = 5?
Ok, so when you are solving an equation, and you have an answer such as 5x=0 , does that mean that it is no solution or all real #s? And, when the answer is 4=4 , does that mean it is no solution or all real #s? And when the answer is 2x=2x, does that mean it is no solution or...
Use the formula (V1*P1) / T1 = (V2*P2)/ T2
anyone can explain?
Why the possible sets are 2^5?
Pipette 3 drops of oil into a test tube of water and shake. Describe what takes place and why? - Would it be the oil settles at the top of the water, because the oil is less dense, and its a non-polar substance, so it doesn't mix with a polar substance (water). Add 1 scoop...
