B - C3H8 + 6O2 -> 3CO2 + 4H2O
THis is because Oxygen is not balanced on both sides, thus defying the law of conservation of matter.
On the reactants side of the equation, there are 12 Oxygen atoms, however, on the products side, there are only 10 Oxygen atoms.
Hope this helps!
Hello!
A solution of a weak base and its conjugate acid act as a better buffer than does a solution of a weak base alone because <span>A solution of a weak base alone has no acid present to absorb added base.</span>
If an acid (In this case HCl) is added to a buffer or a weak base solution, the following reaction happens:
HCl + A⁻ → HA + Cl⁻
In this way, the addition of acid is neutralized by the base.
If a base is added (In this case NaOH), only a solution of a weak base and its conjugate acid can react in the following way:
NaOH + HA → NaA + H₂O
So, a solution of only a weak base can resist the addition of acids but not bases, so it isn't a good buffer.
Have a nice day!
Answer:
Coal puts out more Co2 emissions than Oil or Gas and Nuclear energy plants don't put out any pollution.
Explanation:
Even though Coal is your answer it is actually a very clean form of generating energy. Not only is it very clean but it is the most effecient means. Solar and Wind power can't even come close to the production and turnover that Coal, Gas, and Oil can. Wind Turbines are so innefficent that they somtimes don't even pay off what it took to build them in thier lifetime of service. The production of Wind Turbines puts out more pollution than any of the Coal or Natural Gas Plants. Solar power is not very efficent either but it is on it's way. It is also very expensive.
He did not apply the fifty newtons of greater force! Ok it says when it needed to have the greater force of fifty the person only put 10N out of the fifty, and left out 40N, that is why it did not work properly.
We are given the resistance and voltage of this lamp and we are asked to find the current; the equation that relates these together is Ohm’s Law, V = IR. Simply plug and solve:
V = IR
(220 V) = I(484 Ohms)
I = 0.4545 Amps
The lamp has a current of 0.4545 Amps passing through it under these conditions.
Hope this helps!
