Answer:
Explanation:
Hello,
In this case, for the given constant amount and pressure of the, we apply the Charles' law which allows us to understand the volume-pressure behavior as a directly proportional relationship:
Thus, since we need to compute the volume after the temperature increase (which must be expressed in absolute Kelvins), we obtain V2 as:
Best regards.
Properties of matter which are involved in floating the boats are density and volume as less dense materials present in boats will enable it to float on water.
<h3>What is matter?</h3>
Matter in chemistry, is defined as any kind of a substance which has mass and occupies space that means it possesses volume .Matter is composed up of atoms which may or not be of same type.
Atoms are made up of sub atomic particles which are the protons ,neutrons and the electrons .The matter can exist in various states such as solids, liquids and gases depending on the conditions of temperature and pressure.
The states of matter are inter convertible into each other by varying the parameters of temperature and pressure.

Answer:
2Mg^+ +O2 right arrow 2MgO
Explanation:
Texas has a capital H over it. In weather, a capital red H is an area of high pressure. High pressure areas have sunny, warm weather.
An area with a blue L over it means an area of low pressure and that means stormy weather.
Good luck :) !
Answer:
24x10³
Explanation:
2CO₂(g) + 4H₂O(g) → 2CH₃OH(l) + 3O₂ (g)
The equilibrium constant for this reaction is:
Kc =
The expression of [CH₃OH] is left out as it is a pure liquid.
Now we <u>convert the given masses of the relevant species into moles</u>, using their <em>respective molar masses</em>:
- CO₂ ⇒ 3.28 g ÷ 44 g/mol = 0.0745 mol CO₂
- H₂O ⇒ 3.86 g ÷ 18 g/mol = 0.214 mol H₂O
- O₂ ⇒ 2.80 g ÷ 32 g/mol = 0.0875 mol O₂
Then we calculate the concentrations:
- [CO₂] = 0.0745 mol / 7.5 L = 0.0099 M
- [H₂O] = 0.214 mol / 7.5 L = 0.0285 M
- [O₂] = 0.0875 mol / 7.5 L = 0.0117 M
Finally we <u>calculate Kc</u>:
- Kc = = 24x10³
