Answer:
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Explanation:
This is much more simple than it sounds...
s has 1 orbital; p = 3 orbitals; d= 5 orbitals; f= 7 orbitals. (you just need to memorize this)
A maximum of 2 electrons can occupy each orbital.
<span>The number of orbitals that each atom has is based on the number of electrons it has and by consequence it's position on the periodic table. </span>
The orbitals occur in sequence. Whereby electrons fill first from the lowest energy level (1s) outwards to the highest.
3p = the following sequence.
1s, 2s, 2p, 3s, 3p: these 'sets' can hold the following electrons respectively (2+2+6+2+6) 18 which corresponds with argon on the periodic table. REMEMBER p has 3 orbitals, d has 5 orbitals. So, here there are 9 orbitals.
The sequence through n=4 is:
<span>1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f

Answer:
Mass = 132 g
Explanation:
Given data:
Mass of CO₂ formed = ?
Mass of C burnt = 36 g
Solution:
Chemical equation:
C + O₂ → CO₂
Number of moles of carbon:
Number of moles = mass/molar mass
Number of moles = 36 g/ 12 g/mol
Number of moles = 3 mol
now we will compare the moles of carbon and carbon dioxide.
C : CO₂
1 : 1
3 : 3
Mass of CO₂:
Mass = number of moles × molar mass
Mass = 3 mol × 44 g/mol
Mass = 132 g
The number of feet the track star ran is 4921.26 feet
<h3>Conversion scale </h3>
We can convert meter to feet by using the following conversion scale:
0.3048 meter = 1 feet
<h3>How to cconvert 1500 meters to feet</h3>
The following data were obtained from the question:
- Distance (in meter) = 1500 meter
- Distance (in feet) =?
We can convert 1500 meter to feet as illustrated below:
0.3048 meter = 1 feet
Therefore,
1500 meter = (1500 meter × 1 feet) / 0.3048 meter
1500 meter = 4921.26 feet
Thus, 1500 meter is equivalent to 4921.26 feet
