Answer:
I believe its gas
Explanation:
because it has no symbolic bonds
The water molecule is a polarized molecule containing 2 Hydrogen and 1 Oxygen. Oxygen has a bit more attraction for electrons than Hydrogen. Oxygen is more electronegative, so it’s going to have a stronger pull on electrons.
Answer:
A sample of salt has 1.74 moles of sodium chloride. how many formula units of the ionic compound are in the sample?
Explanation:
Given, 1.74 moles of NaCl.
Since one mole of NaCl consists of --- formula units.
Then, 1.74mol of NaCl contains how many formula units of NaCl?
formula units.
Hence, the given sample has 10.5x10^23 formula units.
Of all the elements, fluorine is the most electronegative and reactive. Fluorine is a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen is it. It produces oxygen and the incredibly corrosive hydrofluoric acid when it combines strongly with water.
<h3>The properties of the oxide and the fluoride?</h3>
- 1. A mixture of oxygen fluorides with an atomic ratio OF in the range of 1.1-2.04 is generated when fluorine and oxygen mixes are easily circulated through a silent electric discharge.
- Depending on where you reside in the UK, fluoride is a naturally occurring mineral that is present in water in variable concentrations. It is added to many types of toothpaste and, in some locations, the water supply through a procedure known as fluoridation because it can aid in the prevention of tooth decay.
- Fluoride stops tooth decay by strengthening the enamel's resistance to acid attack. They also quicken the process of good minerals accumulating in the enamel, further delaying the onset of deterioration. Studies also suggest that fluoride may occasionally be able to stop tooth decay that has already begun.
