Answer:
Explanation:
Hello,
In this case, since the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:
For the given volume and molarity, we solve for the moles of ammonium sulfate (solute) as shown below:
Best regards.
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Answer:
Explanation:
Protons have a positive charge, with a mass of 1 amu.
Neutrons have no charge, also with a mass of 1 amu.
Electrons have a negative charge, with a mass of 1 amu.
This is why when you're calculating the mass of an element or isotope, we only count the number of protons and neutrons.
Answer:
B
Explanation:
The mechanism of this process: the electrolytic cell converts the electrical energy to chemical energy, using external energy source.
Answer:
The root mean squared velocity for CF2Cl2 is 
Explanation:
From the question we are told that
The temperature is 
Root Mean Square velocity is mathematically represented as
Where T is the temperature
MW is the molecular weight of gas
R is the gas constant with a value of 
For CF2Cl2 its molecular weight is 0.121 kg/mol
Substituting values
