Since there are four C-H bonds present in CH4, the bond energy of CH4 is 1652 kJ/mol.
What is bond energy?The term bond energy refers to the energy required to break the bond between two atoms. We have to note that the bond energy of one mole of a molecule depends on the number of individual bonds in the molecule.
For CH4, we know that there are four C-H bonds present. Each C-H bond has a bond energy of about 413 kJ/mol. As such, the bond energy of CH4 is 4( 413 kJ/mol) = 1652 kJ/mol.

An isosceles right triangle has leg lengths of 4 centimeters what is the length of the altitude
Answer:
First calculate the third length of the triangle using the Pythagorean theorem on a right isosceles triangle given by:
hyp=side√2=4√2
Then we know that since this is an isosceles triangle, the altitude is also a median.
We can then use the property of the median relative to the hypotenuse is equal half of it.
median/Altitude=hyp/2=4√2/2=2√2

The population of a town after t years is represented by the function (t)=7248(0. 983)t. What does the value 0. 983 represent in the situation?
Answer:
Exponential function: A function is in the form of; where a is the initial value and b is a factor which decides the exponential function increases or decreases.
If
0<b <1 , then the exponential function decreases.
b> 1, then the exponential function increases.
Given the function:
Since this function f(t) represents the population of a town after t years.
Also, it is an exponential function.
here, b = 0.983 < 1
So, the function f(t) would be decreased by a factor of 0.983.
Therefore, the value 0.983 represents, the population of the town is 0.983 times the population of the town in the previous year.

Identify the relative molar amounts of the species in 0. 10 m kno3(aq). If the species are present in equal amounts, place them in the same box
The relative molar amounts of the given species are;
KnO₃ = 0 M
K⁺ = NO₃⁻ = 0.1 M.
H₃O⁺ = OH⁻ = 1 × 10⁻⁷ M
H₂O = 55.56 M
What is the Relative Molar Amount?
KnO₃ → K⁺ + NO₃⁻
In this dissociation, we see that 1 mole of KnO₃ produces 1 mol of K⁺ and 1 mol of NO₃⁻.
Thus, concentration of KnO₃ is 0 M while the concentration of K⁺ and NO₃⁻ are both 0.1 M.
Now, concentrations of H₃O⁺ and OH⁻ depends solely on the autoionization of water.
Thus, concentration of H₃O⁺ is equal to concentration of OH⁻ = 1 × 10⁻⁷ M. Finally, concentration of H₂O is calculated from it's (1 g/mL) and molar mass of H₂O is 18 g/mol. Thus, concentration = (1/18) * 1000= 55.56 M
