It's the mitochondrion. It it the powerhouse of the cell and deals mainly with energy.
Answer:
1s2: correct.
6s3: incorrect because the subshell s can hold up to 2 electrons.
5f10: correct.
4d3: correct.
2d4: incorrect because the second energy level just has the s and p subshells.
3p10: incorrect because the p subshell can hold up to 6 electrons.
Explanation:
Hello there!
In this case, according to the attached file, which shows the correct orbitals and electrons, we can proceed as follows:
1s2: correct.
6s3: incorrect because the subshell s can hold up to 2 electrons.
5f10: correct.
4d3: correct.
2d4: incorrect because the second energy level just has the s and p subshells.
3p10: incorrect because the p subshell can hold up to 6 electrons.

Answer:
Option A. 0.378M
Explanation:
Data obtained from the question include:
Molarity of acid (Ma) =..?
Volume of acid (Va) = 37.0 mL
Volume of base (Vb) = 56.0 mL
Molarity of base (Mb) = 0.250 M
Next, we shall write the balanced equation for the reaction. This is given below:
HCl + NaOH —> NaCl + H2O
From the balanced equation above,
The mole ratio of the acid (nA) = 1
The mole ratio of the base (nB) = 1
Finally, we can determine the molarity of the acid as shown below :
MaVa/MbVb = nA/nB
Ma x 37 / 0.25 x 56 = 1
Cross multiply
Ma x 37 = 0.25 x 56
Divide both side by 37
Ma = 0.25 x 56 /37
Ma = 0.378M
Therefore, the molarity of the acid, HCl is 0.378M
Answer:
So, H2O means two atoms of hydrogen mixed with one atom of oxygen. All pure water is the same, two parts hydrogen to one part oxygen. ... Water cannot be separated by any physical means.
