Answer: The atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons is 6.
Explanation:
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
For a neutral atom:
Atomic number = Number of electrons = Number of protons
Given : Number of electrons = Number of protons = 6
Thus atomic number = 6
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Given: Number of neutrons = 6
Thus mass number = Number of protons + Number of neutrons = 6+ 6= 12.
The atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons is 6.
Answer:
1.73 × 10²⁴ Molecules
Explanation:
Relation between number of molecules and moles is,
No. of Molecules = Moles × 6.022 × 10²³ Molecules/mol
No. of Molecules = 2.88 mol × 6.022 × 10²³ Molecules/mol
No. of Molecules = 1.73 × 10²⁴ Molecules
True because solids are colder so the particles are in a fixed pattern that join them into a regular pattern
25.9 kJ/mol. (3 sig. fig. as in the heat capacity.)
<h3>Explanation</h3>
The process:
.
How many moles of this process?
Relative atomic mass from a modern periodic table:
- K: 39.098;
- N: 14.007;
- O: 15.999.
Molar mass of 
:
.
Number of moles of the process = Number of moles of dissolved:
.
What's the enthalpy change of this process?
for 
. By convention, the enthalpy change 
measures the energy change for each mole of a process.
.
The heat capacity is the least accurate number in these calculation. It comes with three significant figures. As a result, round the final result to three significant figures. However, make sure you keep at least one additional figure to minimize the risk of rounding errors during the calculation.
Answer:
The first condition is that ocean waters must be above 26 degrees Celsius (79 degrees Fahrenheit). Below this threshold temperature, hurricanes will not form or will weaken rapidly once they move over water below this threshold.
