Because atomic number equals protons and electrons
8-electrons
8-protons
Protons+neutrons=mass
8+8=16 and 8+10=18
8-Neutrons for 16
10- Neutrons for 18
Answer:
Explanation:
Incorrect name correct name
a) calcium dichloride calcium chloride
b) copper(II) oxide copper(I) oxide
c) stannous tetrafluoride stannic fluoride
d) hydrogen chloride acid hydrochloric acid
Answer:
1: A.) adapted
2: A.) habitat destruction
Explanation:
Some (few) animals are capable of adjusting their behaviors in relation to human activity and the changes humans make in their habitat. Most are so well adapted to the details of their habitat that they are incapable of surviving when those details change.
"Because all organisms are <u>adapted</u> to their native habitat, human activities that result in <u>habitat destruction</u> are a major reason for their extinction."
_____
<em>Comment on human activities</em>
My friendly local rodent exterminator observed that rodent activity has picked up substantially, since so much human activity has been curtailed by quarantine orders.
Answer:
Option B is correct More hydrogen carbonate is formed
Explanation:
Step 1: Data given
The Principle of Le Chatelier says 'If the concentration of one of the reaction partners changes, the balance will shift to counteract that concentration change.
Step 2: When adding more H2O
For the equation CO2 + H2O --> H2CO3
If the H2O concentration is increased, the system will attempt to undo that change in concentration by shifting the balance to the right, and so the H2CO3 concentration will increase.
Option B is correct More hydrogen carbonate is formed
There are 20.8 moles of propanol
<h3>Further explanation </h3>
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
1.2 x 10⁵ molecules of propanol
