Answer:
SiS2, silicone disulfide, is a linear, nonpolar compound.
Answer:
2.82 * 10^-25 g
Explanation:
Given that :
Atomic number = 17
Mass of an atom of the element =?
Avogadro's constant = 6.022 * 10^23
The mass of an atom. Of the element is :
Atomic mass / Avogadro's constant
= 17 / 6.022 * 10^23
= 2.82 * 10^-25
=
The amount of sugar in a liquid can be measured using a laser pointer and a prism. Basically, you utilize Snell's Law:
n_i*sin(θi) = n_r*sin(θr), where,
n_i = index of refraction of the incident medium
n_r = index of refraction of the refractive medium
θi = <span>angle of incidence
</span>θr = <span>angle of refraction
</span>
You make use of the laser pointer, prism, and sugar solutions in various known concentrations. You then graph the sugar concentration versus the angle of refraction. You can then determine the amount of sugar in a liquid after determining the angle of refraction of that unknown sugar solution.

E 22
F Ne
Explanation:
From the given table, we can simply complete the given table by identifying the meaning of each column header.
- Number of protons in an atom is the number of positively charged particles in the nucleus of the atom. Protons are positively charged particles in an atom.
- The number of neutrons are the number of neutrally charged particles occupying the nucleus of an atom.
- Atomic number is another term for the number of protons in an atom.
- Mass number is the sum of protons and neutron in an atom.
- The symbol of an element is used represent a particular atom.
Mass number = number of protons + number of neutrons
Atomic number = number of protons = number of electrons in atoms.
