Answer: yes

Explanation:

Answer:

Reaction: Al2(SO4)3 + 3BaCl2 --> 2AlCl3 + 3BaSO4

Type: Double Replacement

Explanation:

1.) First you need to understand what the different reactions are

a.) Synthesis: is a reaction where two or more substances will combine with each other to make one product.

          Ex:  A + B → AB

b.) Decomposition: when one compound breaks down into two or more substances. (Opposite of synthesis)

          Ex:  AB → A + B

c.) Single Replacement: when one element replaces another one in a reaction

          Ex:  A + BC → AC + B

d.) Double Replacement: when the positively charged cations and negatively charged anions of the reactants trade places. Normally this will be the two outer elements combining and the two inner ones combining.

          Ex: AB + CD →  AD + CB

e.) Combustion: when a substance reacts with oxygen gas and releases energy as light and heat.

         Ex: CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g)

2.) From there you can write out the formula of the different reactants and products and balance the equation.

Explanation:

Oxidation reaction

The kind of reaction involving the transfer of electrons or hydrogen away from a molecule is called oxidation.

In the same vein, the molecule that receives the electron or the hydrogen atom is said to be reduced. This means that oxidation cannot exist in isolation without reduction.

In other words, oxidation is defined as:

While reduction is defined as:

The final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.

A styrofoam cup is an insulated material. A styrofoam cup prevents heat gain or looses from the cup. Heat is gained by the water inside the styrofoam cup. The cup prevents exchange of energy with the environment.

When water is lost from the styrofoam cup, the final temperature of the cup may be less than accurate thereby affecting the entire results of the experiment carried out using the cup.

Answer:

Helium is less dense. Because helium is lighter than air, a helium balloon rises, just as an air bubble rises in more dense water

Explanation:

Also why not. It just is.

Answer:

This is due to the fact that helium has a lower density. A helium balloon rises like an air bubble in more dense water because helium is lighter than air. Another gas lighter than air is hydrogen, which is even lighter than helium.

Answer:

BeF2

Explanation:

The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.

The valence electron of an atom determines how an atom goes into bonding.

Beryllium(Be) has 4 electron and has 2 valence electron. To fulfil the octet rule, it can easily give out this 2 electron during bonding.

Fluorine(F) has 9 electrons and 7 valency electrons. To fulfil the octet rule, it readily accepts a single electron.

The correct chemical formula for the product of the reaction when beryllium and fluorine combine is BF₂.

This means 1 atom of beryllium combines with 2 atoms of fluorine to form beryllium fluoride. The beryllium give its 2 valency electrons to the 2 atoms of fluorine. The 2 atoms of fluorine will now have a valency electron of 8 each. The octet rule has been fulfilled at this point.

The list which includes only bulk properties of matter is: C. boiling point, surface tension, vapor pressure.

What is matter?

Matter can be defined as anything that has mass and can occupy space.

Thus, any physical object or substance that is found on planet Earth is typically composed of matter.

The three (3) states of matter:

Since all matter are made up of atoms, they have a property of existing in three (3) distinct states and these include;

A bulk property of matter refers to the property that affects matter as a whole and they are listed as follows:

Answer:

Hydrogen ions decrease. It reduces the concentration of ions.

Explanation:

Heat required is mcΔT=100×0.39×50=1950 J

Solve any question of Thermodynamics with:-

The specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

The specific heat capacity of the substance is calculated as follows;

Q = mcΔФ

where;

c = Q/mΔФ

c = (270) / (4.2 x 25)

c = 2.57 J/g⁰C

Thus, the specific heat of the substance that requires 270 J of energy to raise the temperature is 2.57 J/g⁰C.

This question is mentioning an experiment that is not being described about the volume of the propane gas in an Erlenmeyer before the addition of water.

In this case, since no information is given, it is possible to propose a suggested procedure of how to figure it out via gas laws, specifically, the ideal gas one, since no change is decribed before the addition of water:

[tex]PV=nRT[/tex]

Thus, you can solve for the volume, by dividing both sides by the pressure, so that you will get:

[tex]V=\frac{nRT}{P}[/tex]

Now, to ensure a correct calculation, make sure you have the moles (divide by the molar mass of propane, 44,1 g/mol, if you were given the grams), the temperature in K (add 273.15 if you have degree Celsius), the ideas gas constant as 0.08206 and the pressure in atm, in order to have consistent units.

If you need the volume in milliliters, you will need to multiply the previous answer by 1000 in order to perform the appropriate conversion.

After beginning the experiment with a saturated solution, then increasing the heat, we will be left with an unsaturated solution.

To obtain the saturated solution, we must dissolve sugar in the water. We can say that the solution has become saturated when the solution is no longer able to dissolve more sugar. It has reached its capacity for the solute that it can dissolve in these conditions.

However, the temperature of a solution has an effect on the dissolving limit of the solution. That is, when a solution is heated it becomes able to dissolve more solute. Therefore, if we were to heat a saturated solution, it will be able to dissolve more solute and therefore will no longer be at its limit, meaning it is no longer a saturated solution. It has become unsaturated.
