Answers
Answer:
Explanation:
The term change of phase means the same thing as the term change of state. ... i.e. during phase change, the energy supplied is used only to separate the molecules ; no part of it is used to increase the kinetic energy of the molecules. So its temperature will not rise, since kinetic energy of molecules remains the same.

Anna notices that different types of clothing stick together when they are dried in an electric dryer. When the clothes are pulled apart, they make sparks and a crackling sound due to electric forces of attraction. How can Anna reduce the amount the clothing clings together in the dryer?
Add a substance to the wash that reduces the number of charges transferred.
Increase the temperature of the air in the dryer to weaken the electric forces.
Dry more clothes at the same time so that there is less room for electric forces.
Change the charges on the clothes by running the dryer at a faster speed.
Answers
Answer:
A: Add a substance to the wash that reduces the number of charges transferred.
Explanation:
The attraction between opposite charges make the clothes attract together. To reduce them Increase the temperature of the air in the dryer to weaken the electric forces. Hence, option A is correct.
What is electric dryer?An electric dryer is used to dry the clothes and hair or other substances using electric current. A substance can have both negative and positive charges. The opposite charges will attract together while the negative charges repel.
By exposing clothes to electric dryer it will gain electrons from the dryer and the positive poles of the clothes will attracts it. The electric current from the dryer will make clothes temporarily polarised.
If temperature increases, the intermolecular force of attraction decreases by making the kinetic energy of molecules raised. Therefore by increasing the temperature of air from the dryer the attraction can be reduced.

CFC’s illustrate that technical advances can be a “double-edged” sword as CFC's were made for the advantages but soon or later it came as a disadvantage for environment.
CFC's was discovered with many advantages such as they are stable, non-corrosive, and replacement of harmful ammonia used in refrigerators and air conditioning systems. But soon it is also discovered that CFC's are destroying the upper atmosphere layer called ozone, which is a very big disadvantage for us. CFCs are major contributor to global warming after carbon dioxide.
Hence, it proves that CFC’s shows how technological advancement can be “double-edged” sword.
can someone answer a and b to the file attached?
Answers
Explanation:
The equation of the reaction is given as;
12C + 16 H2 --> 4 C3H8
a. Simplify the equation;
The coefficients are 12, 16 and 4.
4 is a common factor, so divide all through by 4.
12/4 = 3, 16/4 = 4, 4/4 = 1
The equation is given as;
3 C + 4 H2 --> C3H8
b. If 21 moles of C3H8 are formed, how many moles of C was needed.
From the reaction;
3 mol C atoms reacts to form 1 mol of C3H8
x mol would react to form 21 moles of C3H8
3 = 1
x = 21
x = 21 * 3
x = 63 moles

I need help knowing if chemical formulas are balanced or unbalanced I cease to understand this ;-;
Answers
Balancing Chemical Formulas is like simple mathematic systems of equations
Lets look at your second example:
H2 + Cl2 = HCl
Lets replace H with x, and Cl with y.
the equation would now be
2x + 2y = xy (now I know in math x+y does not equal xy, but bear with me)
This would not be correct. For the equation to be true, both sides must yield the same counterpart. To do this, you'd have to add a coefficient to balance out both sides.
Looking at the equation, you know you have to balance the right side, as the left side is adding two things up to getting only half value. So, we will add coefficient of "2" to xy. This means that the balanced chemical equation will now be H2 + Cl2 = 2HCl

If 5.3 moles of magnesium phosphate react with excess sodium chloride how many moles of magnesium chloride will be formed?
Answers
154.0831 g
Explanation:
The formula for the calculation of moles is shown below:
Given: For
Given mass = 41.0 g
Molar mass of = 24.31 g/mol
Moles of = 41.0 g / 24.31 g/mol = 1.6865 moles
Given: For
Given mass = 175 g
Molar mass of = 162.2 g/mol
Moles of = 175 g / 162.2 g/mol = 1.0789 moles
According to the given reaction:
3 moles of Mg react with 2 moles of
1 mole of Mg react with 2/3 moles of
1.6865 mole of Mg react with (2/3)*1.6865 moles of
Moles of = 1.1243 moles
Available moles of = 1.0789 moles
Limiting reagent is the one which is present in small amount. Thus, is limiting reagent. (1.0789 < 1.1243)
The formation of the product is governed by the limiting reagent. So,
2 moles of gives 3 moles of magnesium chloride
1 mole of gives 3/2 moles of magnesium chloride
1.0789 mole of gives (3/2)*1.0789 moles of magnesium chloride
Moles of magnesium chloride = 1.61835 moles
Molar mass of magnesium chloride = 95.21 g/mol
Mass of magnesium chloride = Moles × Molar mass = 1.61835 × 95.21 g = 154.0831 g
1.) What is the maximum number of grams of liquid water at 10C that can be heated to

Answers
Answer:
m = 1 gram
Explanation:
Given that,
Heat, Q = 84 J
The temperature increases from 10°C to 30°C.
We need to find maximum number of grams of liquid water. We know that the heat required is given by :
[tex]Q=mc\Delta T[/tex]
c is specific heat of water, c = 4,200 J/kg°C
Use the above formula to find m. So,
[tex]m=\dfrac{Q}{c\Delta T}\\\\m=\dfrac{84}{4,200\times (30-10)}\\\\m=0.001\ kg[/tex]
or
m = 1 gram
So, the required mass is 1 gram.

What volume (in L) of water vapor will be
produced from the reaction of 4.95 L of ethane
(C2He)?
2C2H6(g) + 702(9) — 4CO2(g) + 6H2O(g)
Answers
Answer:
14.85L of water are produced
Explanation:
Based on Avigadro's law, the volume is directly proportional to the moles of a gas.
Based on the equation:
2C₂H₆(g) + 7O₂(g) → 4CO₂(g) + 6H₂O(g)
2 moles of ethane produce 6 moles of H₂O.
Using Avogadro's law: 2L of ethane produce 6L of H₂O.
The addition of 4.95L of ethane are:
4.95L ethane * (6L H₂O / 2L C₂H₆) =

x mol of any chemical is 6.31 * 10^24
You should look at this before you put it in your calculator. You should think roughly 10.
Now you can set it up as a proportion
1/x = 6.02 * 10^23/6.31 * 10^24 Cross multiply
6.02 * 10^23 x = 1 * 6.31 * 10^24 Divide by 6.02 * 10^23
x = 6.31 * 10^24 / 6.02 * 10^23
x = 10.48 mols.
