The gas will occupy 120 L at STP.
We can use the <em>Combined Gas Laws</em>
.
In 1982, chemists redefined <em>STP</em> as <em>1 bar</em> and 0 °C (273.15 K).
<em>p</em>_1 = 5100 mmHg × (1 atm/760 mmHg) × (1.013 bar/1 atm) = 6.798 bar
<em>T</em>_1 = (29 + 273.15) K = 302.15 K
<em>p</em>_1<em>V</em>_1/<em>T</em>_1 = <em>p</em>_2<em>V</em>_2/<em>T</em>_2
<em>V</em>_2 = <em>V</em>_1 × <em>p</em>_1/<em>p</em>_2 × <em>T</em>_2/<em>T</em>_1
= 20.1 L × (6.798 bar/1 bar) × (273.15 K/302.15 K) = 120 L
Answer:
Explanation: For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value.

Answer:
Model B
Explanation:
Model A shows that light has been reflected, whereas Model B shows the light has been refracted. Light will be refracted as the light enters a more dense medium (glass), from a less dense medium (air).
This website has a really useful, thorough explanation for why this occurs:

At each trophic level only small proportion of energy is transferred to the next level
Answer:
It is a chemical reaction because total mass remain unchanged.
Explanation:
A chemical reaction is represented by a chemical equation which show the reactant and products. Reactants are written on left side of arrow while products are written on right side. The number of atoms are remain same however arrangement of atoms is different on both side.
For example:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
it is known from balanced chemical equation that 6 moles of carbon dioxide react with the six moles of water and created one mole of glucose and six mole of oxygen. The number of atoms are same on both side however arrangement of atoms is different.
While in case of nuclear reaction small change in mass take place.
