Answer:
c) 8.3 x 10^24 molecules
Explanation:
First of all, we convert the volume of the glass of water from mL to 
:
The relationship between mass and volume is:
where
is the density of water
M is the total mass of the glass of water
is the volume of the water in the glass
Solving for M,
Now we know that the mass of a single molecule of water is
The total mass of the water in the glass can be written as
where
N is the number of molecules in the glass of water
Solving for N, we find:
Answer: Both of the compounds contain primary bonding; however, the bonding is of different types. Magnesium chloride (MgCl₂) contains ionic bonds, which are stronger and involve the complete transfer of electrons. Meanwhile, ethane (C₂H₆) also bonds by electron transfer but the electrons are not completely transferred from one atom to another. Instead, they are shared, forming what is known as a covalent bond.
Answer:
a force
Explanation:
Because if we apply force then only an object can slow down, speed up or change direction
During either one, the sun, moon, and Earth are lined up in the same straight line. The difference is whether the moon or the Earth is the one in the "middle".
In telecommunication systems, Carrier frequency is a technical term used to indicate: ... The frequency of the unmodulated electromagnetic wave at the output of a conventional amplitude-modulated (AM-unsupressed carrier), or frequency-modulated (FM), or phase-modulated (PM) radio transmitter.
