Answer:

23.4 mph

Explanation:

The conversion factors are multiplied so that the units cancel out:

(100 meters / 9.58 sec) x (1 mile / 1609 meters) x (60 sec / min) x (60 min /1 hr) = 23.4 mph

How many grams of oxalic acid dihydrate H2C2O4 ·2H2O, a diprotic acid, are needed to react with 20.00 mL of 0.4500 M NaOH?
Sauron [17]
With the given components above, the chemical reaction required to solve the problem is <span>H2C2O4*2H2O + 2 NaOH = 4 H2O + Na2C2O<span>4 where 1 mole of diprotic acid needs 2 moles of NaOH to complete the reaction.In this case, given </span></span><span>0.4500 M NaoH and 0.02 L of it, the moles diprotic acid needed is 0.0045 moles. This is equivalent to 0.351 grams.</span>

Answer:

Volume = 5.73L

Explanation:

Data;

V1 = 3.75L

P1 = 0.980atm

P2 = 0.641atm

V2 = ?

This question involves the use of Boyle's law, which states that, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.

Mathematically,

V = kP, k = PV

P1V1 = P2V2 =P3V3=........=PnVn

P1V1 = P2V2

V2 = (P1 * V1) / P2

V2 = (0.980 × 3.75) / 0.641

V2 = 5.73L

The final volume of the gas is 5.73L
