Answer:
The pressure of the gas after getting compressed is 1.92 L.
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
(At constant temperature)
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
The pressure of the gas after getting compressed is 1.92 L.
Answer:
2
Explanation:
2 is the lowest and the most acidic, which turned it red
The balanced chemical
reaction will be:
C3H8 + 5O2 = 3CO2 +4H2O
We are given the amount of propane gas to be burned. This will be
our starting point.
<span>38.95 </span><span>g C3H8 ( 1 mol C3H8 / 44.1 g C3H8 ) ( 5 mol O2/1
mol C3H8)(32 g O2 / 1 mol O2) =141.32 g O2
Therefore, the reaction consumes approximately 142 grams of oxygen gas.</span>
Alias: Mercuric Hydrogen Carbonate; Mercury(II) Bicarbonate
Formula: Hg(HCO3)2
Molar Mass: 322.6237
The two liquids made a new substance.
<h3>What is a physical and chemical change?</h3>
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
A chemical change occurs when some substances are transformed into different substances, with different nature and properties. In this case when both liquids are mixed a solid is formed. This is an example of a change of state of the liquids reactants to the solid product, which has properties and characteristics different from that of the initial liquids of the mixture which is called a chemical change.
Hence, option D is correct.
