net ionic equation. Aqueous acetic acid (HC2H3O2) is neutralized by aqueous barium hydroxide. i got H^+(g) + OH^-(g) --> H_2O(l) but it is wrong. are my states of matter wrong?

Aspirin (C9H8O4) is produced from salicylic acid (C7H6O3), and acetic anhydride (C4H6O3): C7H6O3 + C4H6O3 ¨ C9H8O4 + HC2H3O2 . (c) What is the theoretical yield of aspirin if 189 kg of salicylic acid is allowed to react with 128 kg of acetic anhydride? (d) If the sit...

what is the minimum degree of a polynomial. How do I find that and how do I find the maximum nuber of turnin points. I know it has to do with n-1 but Idont know how
science- please check my work.

#1. Make up a polynomial that has the following characteristics: crosses the x axis at 1 and 4, touches the x axis at 0 ad 2. and is above the xaxis between 0 and 2. I did (x+1)(x-4)(x^2)(x-2)^2 #2. its an illustration but one of the queestino says what is the minimum degree o...

i cannot find my exact work but i converted 26.5 gal C8H18 to ml then used the density to get grams then converted grams to moles of C8H18 then to moles of )2 then grams of O2

The complete combustion of octane, C8H18, the main component of gasoline, proceeds as follows. 2 C8H18(l) + 25 O2(g) ¨ 16 CO2(g) + 18 H2O(g) Octane has a density of 0.692 g/mL at 20‹C. How many grams of O2 are required to burn 26.5 gal of C8H18? i got 1.22...

is the degree of a polynomial the number of x's or just the highest numbe of x's in a monomial ex: f(x)=-3x^2(x+2)^3
