Explanation:
Rate = 84mL/s
A minute has 60 seconds;
Rate = 84mL/s * 60s = 5040 mL/minute
Volume of blood in a minute = Rate * Number of beeats per minute
Volume = 5040 * 72 = 362880 mL
How long to circulate 3500ml?
1 minute = 362880mL
x = 3500 mL
x = 3500mL min / 362880mL
Math Expression:
Time to circulate 3500ml of blood (min) = 3500ml * 1 minute / Volume of blood at a rate of 84ml/s and 72 beats per minute (ml)
Answer:
Mass of benzene required = 0.78 g
Explanation:
Given data:
Mass of CO₂ produced = 2.66 g
Mass of benzene required = ?
Solution:
Chemical equation:
2C₆H₆ + 15O₂ → 6H₂O + 12CO₂
Number of moles of CO₂:
Number of moles = mass/molar mass
Number of moles = 2.66 g/ 44 g/mol
Number of moles = 0.06 mol
Now we will compare the moles of CO₂ with C₆H₆.
CO₂ : C₆H₆
12 : 2
0.06 : 2/12×0.06=0.01 mol
Mass of benzene required:
Mass = number of moles × molar mass
Mass = 0.01 mol × 78.11 g/mol
Mass = 0.78 g
An electron has a high probability of being in certain regions. Hence, option C is correct.
<h3>What is the meaning of electron cloud?</h3>
The system of electrons surrounding the nucleus of an atom.
The electron cloud model tells us that electrons are found in defined energy states outside of the nucleus of the atom. The lowest possible state for an electron is called its ground state.
The energy levels can only hold a certain number of electrons at any time and the organization of these electrons in the electron cloud is called the atom's electron configuration.
Energy levels describe distances from the nucleus in which electrons can be found. There is a maximum number of electrons that can be found at any particular energy level due to the limitations of its size.
Hence, an electron has a high probability of being in certain regions.
