Answer:
Doing push-ups
Explanation:
When you workout you get hot so the tempeture of ur body increase.
The sublevel designation=6f
The allowed values of the magnetic quantum number are: ml=−3,−2,−1,0,+1,+2,+3
The number of orbitals=7
How are these calculated?
- We are given values for the principal and orbital angular momentum quantum numbers: n=6 ,l=3
- The value of n tells us the shell number. The value of l tells us the type of atomic orbital, which here is an "f" orbital. Therefore, the subshell (sublevel) designation is:6f
- For this subshell the allowed values of the magnetic quantum number are: ml=−3,−2,−1,0,+1,+2,+3
- Each value of ml represents one orbital that holds two electrons. Therefore, we can conclude that there are seven orbitals present at the "6f" subshell, so it has a degeneracy of seven.
What are quantum numbers?
- Quantum numbers are used to describe where around a nucleus a particular electron can be found.
- In any given atom, each electron can be described by four quantum numbers.
- These are n,l,m1,ms
- The values that each number can be are based on a set of rules.

Answer:
0.11%
Explanation:
Without mincing words, let us dive straight into the solution to the question/problem. The first step to solve this question is to write out the chemical reaction, that is the reaction showing the dissociation of acetic acid.
CH3COOH <=======================================> CH3COO⁻ + H⁺
Initially, the amount present in the acetic acid which is = 12M, the concentration for CH3COO⁻ and H⁺ is 0 respectively.
At equilibrium, the amount present in the acetic acid which is = 12 - x, the concentration for CH3COO⁻ = x and H⁺ = x respectively. Note that the ka for acetic acid = 1.8 × 10⁻⁵.
1.8 × 10⁻⁵ = x²/ 14 - x. Therefore, x = 0.0158 M.
The next thing to do is to calculate for the percentage of dissociation, this can be done as given below:
percentage of dissociation = x/14 × 100. Recall that the value that we got for x = 0.0158 M. Hence, the percentage of dissociation = 0.0158 M/ 14m × 100 = 0.11%

Explanation:
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
I think the given is 3 g sample of NaHCO3. then if it will be reacted with an acid, it will produce H2CO3.
so the reaction NaHCO3 + HCl --> NaCl + H2CO3
mas of H2CO3 = 3 g NaHCO3 ( 1 mol NaHCO3 / 84 g ) ( 1 mol H2CO3 / 1 mol NaHCO3) ( 62.03 g / 1 mol )
mass of H2CO3 = 2.22 g H2CO3
