Thank you for posting your question here at brainly. Below is the answer:
At 25 C and 1 atm pressure (the standard state): P is a solid, O2 is a gas, and Cl2 is a gas.
<span>P(s) + O2(g) + Cl2(g) ==> POCl3(l) </span>
<span>To make 1 mole of POCl3, we need to start with 1 mole of P, 1/2 mole of O2, and 3/2 mole of Cl2. </span>
<span>P(s) + 1/2O2(g) + 3/2Cl2(g) ==> POCl3(l) </span>
<span>NOTE: Some people write P as P4(s), in which case you would need 1/4 mole P4.</span>
<span>A 50-gram sample with a half-life of 12 days will have a remaining mass of 25 grams after its 12-day half-life.
Every cycle of a half-life, the sample will lose half of its mass, so if the half-life, itself, is 12 days and the time period passing is 12 days, one half-life has passed and the material will be halved.</span>
<span>Answer:
Enthalpy Change = (6 x -393.5) + (7 x -285.8) - (-204.6) + (19/2) 0.....???
like.. (6 x Enth CO2) + ( 7 x Enth H2O) - (Enth C6H14) + (19/2) Enth O2</span>
What's the answer? It asked to be 20 characters long so just writing this.
HCl Acid + Sodium Hydroxide ----> Sodium Chloride + water.
<u>Explanation</u>:
- The reaction between an acid and a base is known as a neutralization reaction. The reaction of an acid with a base to give salt, water and heat is called neutralization.
- When hydrochloric acid reacts with sodium hydroxide, sodium chloride and water are produced.
HCl + NaOH → NaCl + H2O + Heat
- The heat evolved in the neutralization reaction raises the temperature of the reaction mixture.
- An electro-electrodialysis process (EED) is utilized to create HCl and NaOH from exchange NaCl. NaOH and HCl arrangements with purity higher than 99.9% are acquired. The experimental estimations of the transitions for HCl and NaOH are contrasted and values determined from the incorporation of the Nernst–Planck electro dispersion conditions.
