The air pressure in a tire is 2.38 atm. What is the pressure in kilopascals.
Anna71 [15]

Answer:

The answer is

<h2>241.15 kPa</h2>

Explanation:

To find the pressure in kilopascals we must first find the pressure in Pascal

To find the pressure in Pascal we use the conversion

1 atm = 101 , 325 Pa

If 1 atm = 101325 Pa

then 2.38 atm = 2.38 × 101325

= 241153.5 Pa

Converting it into kPa we have the final answer as

<h3>241.15 kPa</h3>

Hope this helps you

What impact would adding twice as much na2co3 than required for stoichiometric quantities have on the quantity of product produc
inn [45]

The product will not be affected by the addition of twice as much Na₂CO₃.

<h3>What is Limiting reagent in stoichiometry ?</h3>
  • The maximum quantity of the end product determined by a balanced chemical equation is known as the Stoichiometry.
  • The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced, and the one which remains unconsumed after the final reaction is in Excess.
  • Calculate the moles of each reactant present and contrast it with the mole ratio of the reactants in the balanced equation to determine which reactant is the limiting one.

Here,taking the stoichiometry into consideration, we find that the reaction happens with 1:1 ratio; so, adding twice the amount of Na₂CO₃ will  lead to its excess making the other the limiting reactant, hence, it would not affect the yield of the product.

To know more about the Limiting reactant, refer to:
