The resulting pressure will be 2.03 atm.
<u>Explanation:</u>
As per the Boyle's law, the volume of a particular mass of a gas is inversely proportional to its pressure applied. As pressure increases, the volume decreases.
P1V1 = P2V2
Here P1 = 1.35 atm
V1 = 5.15 L
P2 = ?
V2 = 3.43 L
The above equation can be rewritten to get P2 as,
P2 =
Now, we can plugin the above values as,
P2 =
= 2.03 atm
As per the law said, the volume is compressed as the pressure increases.
Explanation:
1.
i. Measure the initial volume of water in a graduated cylinder.
ii. Now submerge the irregularly shaped metal into water in a graduated cylinder.
iii. Measure the final volume of water.
iv. The difference between the final volume and the initial volume is the volume of the irregularly shaped metal.
2.
When adding the irregularly shaped metal into the glass graduated cylinder. Make sure that the irregularly shaped metal is completely submerged into the water.
Answer:
No (If we are talking about pure water)
Explanation:
Water is a compound. Each molecule is made up of only 2 Hydrogen atoms and 1 Oxygen atom.
Answer: 1 mol C8H18 produces 9 mol H2O
Explanation: reaction : C8H18 + 12.5 O2 ⇒ 8 CO2 + 9 H2O
Answer:
The answer is
<h2>877 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
density = 19.3 g/cm³
volume = 44.9 cm³
The mass of the gold bar
mass = 19.3 × 44.9 = 866.57
We have the final answer as
<h3>877 g</h3>
