Answer:
Covalent bonds
Explanation:
A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.
<u>Answer:</u> The correct answer is Option 1.
<u>Explanation:</u>
There are three subatomic particles in an atom. They are: electrons, protons and neutrons.
- <u>Protons:</u> They carry positive charge and are found in nucleus.
- <u>Electrons:</u> They carry negative charge and are found around the nucleus.
- <u>Neutrons:</u> They dos not carry any charge and are found in nucleus.
Mass of protons and neutrons are almost same and they both contribute to the mass of an atom.
Mass of electrons is very negligible as compared to protons and neutrons.
Masses of the subatomic particles:
Mass of protons = 1.007276 u
Mass of neutrons = 1.008664 u
Mass of electrons = 0.00054858 u
Hence, the correct answer is Option 1.
Answer:
To determine the number of atoms of Boron that are present within 3.61 grams of Boron Trifluoride, it would be best to convert the grams to moles of the compound and then after that use the Avogadro's number to determine the number of molecules and then use the 1 to 3 ratio to determine the total number of Boron atoms.
Answer : HazCom
Explanation : Hazard communication which is also known as HazCom, is a set of processes and procedures that every employers and importers must implement in their workplace to effectively communicate hazards associated with chemicals during handling, shipping, and any form of exposure.
The OSHA Hazard Communication Standard is a U.S. regulation which governs the evaluation and communication of hazards associated with chemicals at the workplace. It is typically not attached to any specific chemical container but is stored in the workplace.
According to Google, Sodium Hydroxide (NaOH) reacts with protic acids to produce water and/or corresponding salts.
Sodium Hydroxide is a solid, but it can be dissolved into water, making it a liquid.
The state of matter of NaOH (sodium hydroxide) would have to be Aqueous (aq), which, in chemistry, means that its solvent is water, making it a liquid.
