The elements involved here are non-metals. The bond that forms between non-metals is a covalent bond where each atom shares one or more electron with the other so that both become stable. The number of shared electrons has to be equal for both.
Now, hydrogen needs only one electron to fill its outermost level and be stable and the same goes for fluorine, therefore, each of them shares one electron with the other.
Based on this, the answer would be:
<span>Hydrogen and fluorine share one electron with each other.</span>
Answer:
hey D!
Explanation:
D. Lateralization
The brain is divided into two halves, called hemispheres. There is evidence that each brain hemisphere has its own distinct functions, a phenomenon referred to as lateralization. The left hemisphere appears to dominate the functions of speech, language processing and comprehension, and logical reasoning, while the right is moredominant in spatial tasks like vision-independent object recognition (such as identifying an object by touch or another nonvisual sense). However, it is easy to exaggerate the differences between the functions of the left and right hemispheres; both hemispheres are involved with most processes. Additionally, neuroplasticity (the ability of a brain to adapt to experience) enables the brain to compensate for damage to one hemisphere by taking on extra functions in the other half, especially in young brains.
Explanation: We are given three balloon carrying different charges: One having positive charge, one having negative charge and one having no charge.
When we bring positive rod near these three balloons, all of them behave differently.
According to the Coulomb's Law:
Like charges repel each other and unlike charges attract each other.
- When we bring positive rod towards the balloon having positive charge, the balloon will move away from the rod, because like charges repel each other.
- When we bring positive rod near negative balloon, the balloon will be attracted to the rod because unlike charges attract each other.
- But, when we bring positive rod towards the balloon having no charge, the charges will be induced in the balloon. Although the balloon is neutral in nature but it will still carry some +ve or -ve charges. So, when the positive rod is bought near neutral ball, the negative side of the balloon will get attracted towards the rod and positive side will be repelled. From this, we say that the rod has induced some charges in the balloon.
Answer:
22.39g of NaBr
Explanation:
First let us write a balanced equation for the reaction. This is illustrated below:
2Na + Br2 —> 2NaBr
Molar Mass of Na = 23g/mol
Mass of Na from the balanced equation = 2 x 23 = 46g
Molar Mass of NaBr = 23 + 80 = 103g/mol
Mass of NaBr from the balanced equation = 2 x 103 = 206g
From the equation,
46g of Na produced 206g NaBr.
Therefore, 5g of Na will produce = (5 x 206)/46 = 22.39g of NaBr
Answer:
114 K
Explanation:
Given data
- Volume of oxygen (V): 629 mL = 0.629 L
- Pressure of oxygen (P): 0.500 atm
- Moles of oxygen (n): 0.0337 mol
We can calculate the temperature at which the student collected the oxygen using the ideal gas equation.
The oxygen gas was collected at 114 K.
