How could you change the height of a cone so that its volume would remain the same when its radius was tripled?
V1 = (1/3)(pi)(r12)(h1) V2 = (1/3)(pi)(xr12)(h2) V1 = V2 , which means that: (1/3)(pi)(r12)(h1) = (1/3)(pi)(xr12)(h2) Divide both sides by (1/3)(pi) and you get: (r12)(h1) = (xr12)(h2) -> (r12)(h1) = x2(r12)(h2) Divide both sides by (r12) and you get: h1 = x2(h2) -> h2 = (h1)/x2 For example: Cone1: r1 = 10, h1 = 10 Cone2: r2 = 30, h2 = (10/32) = 10/9 = 1.11111111 Then to check: Volume of a cone = (1/3)(pi)(r2)(h) V1 = (1/3)(pi)(102)(10) V1 = 1047.197551 = V2 1047.197551 = (1/3)(pi)(302)(h2) h2 = 1047.197551/((900pi)/3) h2 = 1.111111111 = 10/9

How many moles of H2 are needed to produce 12.36 of NH3?
To solve this problem, we need to use the balanced chemical equation for the reaction between H2 and NH3. Given that the molar ratio between H2 and NH3 is 3:2, we can set up a proportion to find the number of moles of H2 needed. Using the formula: Moles of H2 = 12.36 moles NH3 * (3 moles H2 / 2 moles NH3) = 18.54 moles H2.
What does the formula h2 o2 mean?
Hydrogen peroxide
Is H2 SO 4 A nonelectrolyte?
ya . H2 SO4 is an salt .(strong electrolite) because it is a salt (i=3).
How many moles of NH3 are produced when 1.4 moles H2 reacts?
Balanced equation. N2 + 3H2 --> 2NH3 1.4 moles H2 (2 moles NH3/3 moles H2) = 0.93 moles NH3 produced =======================
How many hudrogen molecule are there in 10grams of hydrogen?
There are approximately 1340 molecules of hydrogen in 10 grams of hydrogen.
What does the 2 mean in the formula h2?
it means how many carbons there are
When 3 moles of N2 reacts with 2 moles of H2 the number of produced moles of ammonia equal?
The reaction between nitrogen and hydrogen to form ammonia is: N2 + 3 H2 → 2 NH3 The above is the reaction for the Haber process in the industrial synthesis of ammonia. For a given proportion of 3 N2 to 2 H2 (or in ratio terms equivalent to 4.5 N2 to 3 H2), we see that H2 is the limiting reactant. Thus according to the stoichiometry of the reaction, 2 moles of H2 will form 1.33 moles of NH3.
What is the formula of H2?
H2 represents a molecule of hydrogen gas, which consists of two hydrogen atoms bonded together. Its chemical formula is simply H2.
