Answer:
= 1.0593 g
Explanation:
1.1% NaCl by mass, means;
1.1 g per 100 g = 0.011
Therefore; the amount of NaCl present in 93.6 g of the solution is;
= 0.011 × 96.3 g
<u>= 1.0593 g</u>
The Isotope Notation occur by adding the Superscript showing Mass Number and Subscript showing Atomic Number to the Left of the Element Symbol.
Example,
ᵇₐX
Where;
b = Mass Number
a = Atomic Number
X = Symbol
For Hydrogen Isotopes:
1) Protium: 1 Proton , 0 Neutron
¹₁H
2) Deuterium: 1 Proton , 1 Neutron
²₁H
3) Tritium: 1 Proton , 2 Neutron
³₁H
Answer:
The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
Answer:
Chlorine(Cl)
Explanation:
Because the shielding effect(by the inner electrons) remains the same but the nuclear charge is increasing(due to the increasing number of protons)
So Chlorine has the highest number of protons...so its outter electrons tend to expierence the most nuclear attraction hence making it more harder to remove the first electron
Answer:
Gravity.
Explanation:
Black holes in the center of most galaxies hold the galaxy together by gravity. Everything is sucked towards the center and kept together.
