Answer:
383.90K
Explanation:
P1 = 851mmHg
T1 = 330K
T2 = ?
P2 = 990mmHg
To solve for P2, we have to use pressure law which states that the pressure of a fixed mass of fixed is directly proportional to its temperature provided that volume remains constant
Mathematically,
P = kT, k = P/T
P1 / T1 = P2 / T2 = P3 / T3 =.......=Pn / Tn
P1 / T1 = P2 / T2
T2 = (P2 × T1) / P1
T2 = (990 × 330) / 851
T2 = 383.90K
The final temperature of the gas is 383.90K
Answer:
Chlorowanie wody jest procesem względnie tanim – koszt zbudowania samej instalacji do dezynfekcji, jak również koszt operacyjny wytworzenia 1 metra sześciennego uzdatnionej chlorem wody jest niższy od dezynfekcji wody za pomocą ozonu. Źródłem chloru w procesie dezynfekcji jest zazwyczaj podchloryn sodu, rzadziej dwutlenek chloru.
Explanation:
Answer is: in chemical reaction with with weak acid, sodium carbonate produce carbonic acid (H₂CO₃), which decomposes into carbon(IV) oxide (fizzy bubbles) and water.
Balanced chemical reaction:
Na₂CO₃ + 2HClO → CO₂(g) + H₂O + 2NaClO.
Chemical decomposition is the separation of a carbonic acid into water and carbon dioxide: H₂CO₃ → CO₂ + H₂O.
Answer:
YES
Explanation:
The reliability of bar graph showing weather measurement in a day depends on the reliability of the data sources. If the sources of data are correct and the graph is constructed correctly, then the bar graph is reliable.
