Babies are created through sexual actions from a male and female. At birth they are not able to walk because their legs are not strong enough to support their body weight and they can't talk because they don't know the language. They learn it by listening
I thought it maybe D. the skeleton provides support and the muscles move the bones
Answer:
Electron pair geometry- tetrahedral
Molecular geometry- Trigonal Pyramidal
Explanation:
PCl3 has four electron domains on the outermost shell of the central atom in the molecule. This implies that it has a tetrahedral electron pair geometry according to Valence Shell Electron Pair Repulsion theory.
These four electron pairs are composed of three bond pairs and one lone pair. The presence of a lone pair of electrons leads to a trigonal pyramidal molecular geometry due to electron pair repulsions.
The notation is actually written in this way (shown in the attached picture). The X is the symbol of the element. So, for potassium, the symbol is K. The A represents the mass number of the isotope. In this case, that would be equal to 39. The Z represents the atomic number of potassium, which is 19. Therefore, the symbol for the isotope is:
³⁹₁₉K
BaCl2 + Na2SO4-----> 2NaCl + BaSO4(s)
net ionic equation- Ba+2 + SO4 -2 -----> BaSO4 (s)
