The answer is D. And if it is equally shared it is nonpolar covalent bond
The de Broglie hypothesis proposed that all particles have wave-like properties, with the wavelength being inversely proportional to the velocity of the particle.
Therefore as the velocity (speed in this question) increases, the wavelength *decreases*.
Answer:
0.85 mole of PBr3.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
3Br2 + 2P —> 2PBr3
From the balanced equation above,
3 moles of Br2 reacted to produce 2 moles of PBr3.
Therefore, 1.27 moles of Br2 will react to produce = (1.27 x 2)/ 3 = 0.85 mole of PBr3.
Therefore, 0.85 mole of PBr3 is produced by the reaction.
Answer:
SCIENCE is a process that involves the collection of information and ideas supported by evidence because science is the knowledge gained through observations and experiments
Explanation:
i hope this will help you :)
Explanation:
Anions and cations have different atomic sizes than the neutral atoms.
When the bromine atom becomes an anion, it ______ in size.
Anions involves gaining extra electrons. This basically leads to increased repulsion between the electrons and thereby increasing the size. Anions are always larger than the neutral atoms.
This means the answer is A. Increase
When the strontium atom becomes a cation, it ______ in size.
Cations involves losing valence electrons. This basically leads to a decrease in electron shells and electron repulsion thereby reducing the size. Cations are always larger than the neutral atoms.
This means the answer is B. Decrease
