Explanation:
Example #1: How many moles of oxygen will occupy a volume of 2.50 L at STP? Standard ... What is the volume of gas at 2.00 atm and 200.0 K if its original volume was ... P2 = 2.00 atm 2.000tm) 273k. T=273k. 200.0k. Tz= 200.0k. V, = 200.0L ... A gas has a pressure of 0.370 atm at 50.0°C. What is the pressure at standard.
Answer: between 6.5 and 8.5
Explanation:
As shown in my science book it appears in the ph scale
Answer:
When C1 is labeled in glucose, it ends up in the methyl group of pyruvate.
Aldolase cleaves a hexose into two trioses.
[See the image attached].
Asterisk indicates the label.
When C1 is labeled in glucose, it ends up in the carboxyl group of pyruvate.
Therefore option c , i.e. The substances in both test tubes are reactive only at high temperatures. is the only statement which is NOT supported by the student's observations.
<h3>What is the reaction between Magnesium and Hydrogen ?</h3>
Magnesium reacts with hydrochloric acid to produce hydrogen gas
Mg (s) + 2 HCl (aq) → MgCl₂ (aq) + H₂ (g)
In this reaction, the magnesium and acid are gradually used up , which can be seen in the test tube 2 .
A chemical reaction is taking place in Test tube 2 ,
Hydrogen gas is released in test tube 2 ,
Energy is released in the reaction involving hydrochloric acid and we can see in test tube 2 the reaction is going on
therefore option C i.e. The substances in both test tubes are reactive only at high temperatures. is the only statement which is NOT supported by the student's observation.
To know more about the chemical reaction between Magnesium and Hydrogen and this test.
