Answer: 1870. 67mL
Explanation:
NaOH + HCl —> NaCl + H2O
nA = 1, Ca = 0.015M, Va =?
nB = 1 Cb = 0.244 M, Vb = 115 mL
CaVa / CbVb = nA/nB
(0.015xVa)/(0.244x115) = 1/1
Va = (0.244x115) /0.015 = 1870. 67mL
To create the Lewis structure we need to take into account the octet rule: atoms tend to gain, lose or share electrons to complete their valence shell with 8 electrons.
C belongs to Group 4A in the periodic table so it has 4 valence electrons. It needs to share 4 pairs of electrons to complete the octet.
F belongs to Group 7A in the periodic table so it has 7 valence electrons. Each F needs to share 1 pair of electrons to complete the octet.
As a consequence, in CF₄, C will form a single bond with each F and all the octets will be complete.
<h3>
Answer:</h3>
7.182K
<h3>
Explanation:</h3>
From the question we are given;
- Initial temperature, T1 = 275 K
- Final temperature, T2 = 395 K
- Initial volume, V1 = 5 L
We are required to calculate the final volume, V2
- Charles's law is the law that relates the volume of a gas and its temperature.
- It states that the volume of a fixed mass of a gas and its absolute temperature are directly proportional at a constant pressure.
- Therefore;
To calculate, V2 we rearrange the formula;
Therefore, the ending volume will be 7.182K
Answer:
Complex System
Explanation:
Given that, a descriptive scientific investigation is one of the three main types of investigation which formulates and quantify the natural phenomenon. This natural phenomenon oftentimes involves Complex System, such as microscopic organisms, thereby, scientists often make observations to understand the interacting parts of this COMPLEX SYSTEM
Hence, the right answer is a COMPLEX SYSTEM
