To determine the structure of the molecule, we add the number of atoms that is bonded to the central atom. In this case, we have 4 fluorine atoms bonded to the central atom, carbon. We then look at the one pair of electrons and then choose the correct arrangement. For this case, the correct shape would be a tetrahedral. Therefore, the bond angle would be 109.5 degrees.

Based on the valence shell electron repulsion theory, the bond angle between the atoms of Fluorine in carbon tetrafluoride is 109.5 degrees. CF4 having a sp3 hybridization would follow the tetrahedral shape which is the most stable conformation.

Balancing nuclear equations is slightly different than balancing chemical equations. The major difference is that in nuclear rea

vesna_86 [32]

Answer:

The correct answer is - 4.

Explanation:

As we known and also given that the total of the superscripts that is mass numbers, A in the reactants and products must be the same.The mass of products A can understand and calculated by this -

The sum of the product mass number of products = mass of reactant

237Np93 →233 Pa91 +AZX is the equation,

Solution:

Mass of reactants = 237

Mass of products are - Pa =233 and A = ?

233 + A = 237

A = 237 - 233

A = 4

So the equation will be:

237Np93 →233 Pa91 +4He2 (atomic number Z = 2 ∵ difference in the atomic number of reactant and products)

What should scentist use after completing a scientific investigation

Zinaida [17]

Answer:

An Educated Guess

Explanation:

After the scientist is done with the experiment he should do an educated guess, they use the data from the experiments to make charts and graphs to communicate the results of the experiment. After the scientists makes the hypothesis, they perform this procedure.

Why are these graphs misleading

ch4aika [34]

Although there isn’t a picture a graph can be misleading when it doesn’t start at zero, it doesn’t give accurate information, it skips too many numbers, the vertical scale is too big or too small. Hope this helps

Are the bonds in each of the following substances ionic, nonpolar covalent, or polar covalent? Arrange the substances with polar

KengaRu [80]

Covalent bonds can be classified as nonpolar and polar covalent given the electronegativity difference between two atoms (ΔEN).

Nonpolar covalent bond electrons are shared equally between two atoms, polar covalent bond electrons are shared unequally, atoms have partial charges, ionic bond electrons are completely transferred to one atom, full charges present. Therefore, the greater the electronegativity difference, the greater the bond polarity. Let's determine the types of bonds present in the compounds and arrange the ones with polar covalent in order of increasing ΔEN. Sulfur and oxygen are both nonmetals so the substance is covalent. Sulfur has EN = 2.5 and oxygen has EN = 3.5. Since there is an electronegativity difference, the S−O bonds in the substance can be classified as polar covalent bonds.
