Answer:
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia. ... If that velocity is zero, then the object remains at rest.
Explanation:
Oxygen is participating in non-polar covalent bond(s)
Oxygen forms 2 covalent bond.
This is because oxygen atoms have 6 valence electrons. This means that it has 2 lone pairs and 2 unpaired electrons that are shared in order to achieve octet configuration.
In this chemistry, the 2 lone pairs on the oxygen are not shared with any other atoms. Instead; they are assigned to the oxygen atom. The formal charge on the oxygen atom is zero. Oxygen's atomic number is 8 and is equal to the sum of the number of its valence and inner shell electrons.
<h3>What is non-polar covalent bonding?</h3>
Nonpolar covalent bonding is a kind of covalent bond in which the bonding electrons are shared equally between the two atoms.

Answer:
2M
Explanation:
Molarity refers to the molar concentration of a solution. It can be calculated by using the formula as follows:
Molarity (M) = number of moles (n) ÷ volume (V)
Based on the information provided in this question, 2 moles of salt is dissolved to form 1 liter of solution. This means that n = 2mol, V = 1L
Molarity = n/V
Molarity = 2/1
Molarity = 2M
The lab coat is not thick enough to protect you from ionizing radiation.
<h3>What is radiation?</h3>
Radiation is a form of energy that we can not see with our optical eyes. We know that radiation could have a damaging effect on the body. The sort of radiation that could have a damaging effect on the body is what we call ionizing radiation.
We know that an ionizing radiation could only be stopped by a thick vest such as a lead coat. If you are wearing a lab coat, you are not safe because the lab cat is not thick enough to protect you from ionizing radiation.

Answer:
Number of moles of iron are 4 mol.
Explanation:
Given data:
Mass of iron = 223.4 g
Number of moles = ?
Solution:
Molar mass of iron = 55.85 g/mol
Formula:
Number of moles = mass/molar mass
Number of moles = 223.4 g/ 55.85 g/mol
Number of moles = 4 mol
