How much HCl exists in 347 mL of 0.48 M
solution of HCI?
Answer in units of mol.
Answers
Answer:
Number of moles of HCl = 0.17 mol
Explanation:
Given data:
Volume of solution = 347 mL
Molarity of solution = 0.48 M
Number of moles of HCl present = ?
Solution:
Formula:
Molarity = number of moles of HCl / volume in L
Volume in L:
347 mL× 1L / 1000 mL
0.347 L
by putting values in formula:
0.48 mol/L = number of moles / 0.347 L
Number of moles = 0.48 mol/L × 0.347 L
Number of moles = 0.17 mol

B. Metals with nonmetals, because their difference in electronegativity is below 1.7
C. Nonmetals with nonmetals, because they're difference in electronegativity is above 1.7
D. Nonmetals with nonmetals, because of difference in electronegativity is below 1.7
Answers
Answer:
D. Nonmetals with nonmetals, because of difference in electronegativity is below 1.7
Explanation:
The types of atoms that typically form covalent bonds are non-metals with non-metals because of the difference in their electronegativity which is below 1.7.
In some instances, the difference can even be zero when dealing with homonuclear substances.
Covalent bond are formed between two or more atoms having low electronegativity differences between them. Each of the atoms share their valence electrons to be able to mimic the noble gases. The participating atoms will put down an unpaired electron to be used in forming a shared pair of electrons between them.Draw a simple transverse wave and label the wavelength.draw it on a piece of paper

A chemist determines by measurements that moles of bromine liquid participate in a chemical reaction. Calculate the mass of bromine liquid that participates. Be sure your answer has the correct number of significant digits.
Answers
Answer:
This question is incomplete as it lacks the number of moles of Bromine. The complete part is as follows: 0.0900 moles of bromine liquid participate in a chemical reaction.
The answer is 7.191g
Explanation:
The number of moles in a substance can be calculated thus;
moles = mass/molar mass
Atomic mass of Bromine = 79.9g/mol
According to the question, the chemist determines by measurements that 0.0900 moles of bromine liquid participate in a chemical reaction. To calculate the mass of bromine liquid that participates, we say;
Mass = moles × molar mass
Mass = 0.0900 × 79.9
Mass = 7.191g
Therefore, 7.191g of Bromine will participate in the chemical reaction.

Answers
Answer:
This is the tendency for particles in suspension to settle out of fluid in which they are contained and come to rest against a barrier.
Explanation:
In sedimentation, the particles are in a fluid and under the influence of forces , for example, gravitational forces, they settle and then come to rest when faced with a barrier.
The settling process is the process in which the particles fall out of liquid and sedimentation is the end of the process.

The value of x = 97
The unknown angles : 97°,97°, 107° and 59°
Further explanationOne variable linear equation is an equation that has a variable and the exponent number is one.
Can be stated in the form:
[tex]\large{\boxed{\bold{ax=b}}[/tex]
or
ax + b = c, where a, b, and c are constants, x is a variable
The parallelogram has total angle of 360°.
The value of each of the 4 angles of the parallelogram :
1. x°
2. x°
3. x+10°
4. 59°
The sum of the four angles of this parallelogram is :
[tex]\tt x+x+x+10+59=360[/tex]
So that the mathematical equation becomes (by combining the like terms) :
[tex]\tt 3x+69=360\\\\3x=291\\\\x=97[/tex]
So the value of the four angles (by entering the x value)
1. 97°
2. 97°
3. x+10=97+10=107°
4. 59°
The diameter of a helium atom is about 1 3 102 pm. Suppose that we could line up helium atoms side by side in contact with one another. Approximately how many atoms would it take to make the distance from end to end 1 cm
Answers
Answer:
1 × 10⁸ He atoms
Explanation:
Step 1: Given data
Diameter of a helium atom (d): 1 × 10² pmTotal distance to be covered (D): 1 cmStep 2: Convert "d" to meters
We will use the conversion factor 1 m = 10¹² pm.
1 × 10² pm × (1 m / 10¹² pm) = 1 × 10⁻¹⁰ m
Step 3: Convert "D" to meters
We will use the conversion factor 1 m = 100 cm.
1 cm × (1 m / 100 cm) = 0.01 m
Step 4: Calculate the number of atoms of He required
We will use the following expression.
D/d = 0.01 m / 1 × 10⁻¹⁰ m = 1 × 10⁸

Answers
Answer:
may involve a change in total mass
involve very high-energy changes
involve changes in nuclides when decay occurs
Explanation:
A nuclear reaction is different from a typical chemical reaction. The reaction occurs within the nucleus and involved nuclear materials.
Most nuclear reactions involves a change in mass due to the attenuation of the nuclear materials. Mass is converted to energy in nuclear reactions. Nuclear reactions are usually very high energy processes and they release a significant amount of energy. The nuclide changes as new atoms are formed by the process.The electricity accounts of residents in a very small town are calculated as follows: v If 250 units or fewer are used, the cost is 2 cents per unit; v If more than 250 but not more than 800 units are used, the cost is $10 for the first 250 units and 5 cents for every unit in the excess of 250. v If more than 800 units are used, the cost is $35 for the first 800 units plus 10 cents for every unit in the excess of 800. v A basic service fee of $5 is charged, no matter how much electricity is used. Write a user-defined function program to calculate the fees of any electricity unit, and then write a command to calculate the fee of a resident who used 700 electricity units.
Answers
Answer:
For you first question about the defined function program:
if ( v ≤ 250 ) {
set p to (5 + v*.02)
}
elseif ( 250 ≤ v ≤ 800 ) {
set p to (5 + 2500 + (v - 250)*.02)
}
else {
set p to (5 + 28000 + (v - 800)*.1)
}
This function will first check if the user has used how many units and decide which category that user falls into.
Then, it uses that information to execute a command to calculate how much money that user should pay for the electricity bill, factoring in the extra demands from the question.
For your second question:
(5 + 2500 + (700 - 250)*.02)
= (3000 + 450*.02)
= (3000 + 9)
= 3009
The customer should have paid 3009 dollars.

Answers
The phrase which best describes gravitational attraction is the pull
between objects with mass.
What is Gravitational attraction?Gravitational attraction is the attraction which occurs between two objects
with mass. The force of attraction has a magnitude which is directly
proportional to the masses of the two objects and inversely proportional to
the square of the distance between the two objects.
This is the reason why option D i9s the most appropriate option as it deals
with pull or attraction.
