Answer: Neutralization Reaction

Explanation: Acid-Base Indicator are the substances which are responsible for the observance of the color change in the titration mixture due to the change in pH at the end point.

Acid -Base reactions are those in which acid and base reacts to get neutralized and formation of the salt takes place.

When the amount of acid becomes equal to the amount of base, end point is reached where the color of the solution changes.

This reaction is neither a decomposition reaction as the reactant is not getting decomposed into simpler elements nor a combustion reaction as it is not taking place in presence of oxygen . It can be a part of combination reaction but it is more primarily known as Neutralization reaction.

An acid base reaction is a netutralization reaction which produces water and salt. It is not a decomposition since the reactants are not broken to simpler elements nor combustion since it does not uses oxygen as reactant.

Convert 150 kPa to atmospheres. *

lakkis [162]

Answer: 1.48 atmosphere

Explanation:

Pressure in kilopascal = 150

Pressure in atmosphere = ?

Recall that 1 atmosphere = 101.325 kilopascal

Hence, 1 atm = 101.325 kPa

Z atm = 150 kPa

To get the value of Z, cross multiply

150 kPa x 1 atm = 101.325 kPa x Z

150 kPa•atm = 101.325 kPa•Z

Divide both sides by 101.325 kPa

150 kPa•atm/101.325 kPa = 101.325 kPa•Z/101.325 kPa

1.48 atm = Z

Thus, 150 kPa is equivalent to 1.48 atmospheres

4. Which of these are environmental costs of using

Vinvika [58]

Answer: b. The waste generated is hazardous and must be disposed of.

c. Nuclear material can be spilled into the ocean if reactors are near the coast.

d. A large amount of cold water is generated, which must be stored somewhere.

Explanation:

The main environmental costs for produced during the nuclear power plant consists of procurement of fuel and the thermal load is also produced with cold water discharge in the sea. This can contaminate the sea, hence, must be stored somewhere. The nuclear waste consists of radioactive substances which are hazardous for the environment. The nuclear based electricity does not produce carbon dioxide.

What are valence electrons ?

Arada [10]

Answer:In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

If 11.0 g of ccl3f is enclosed in a 1.1 −l container, will any liquid be present?if so, what mass of liquid?

Anastasy [175]

Considering that CCL3F gas behave like an ideal gas then we can use the Ideal Gas Law
PV = nRT, however is an approximation and not the only way to resolve this problem with the given data..So,at the end of the solution I am posting some sources for further understanding and a expanded point of view. 

Data: P= 856torr, T = 300K, V= 1.1L, R = 62.36 L Torr / KMol 

Solving and substituting in the Gas equation for n = PV / RT = (856)(1.1L) /( 62.36)(300) = 0.05 Mol. This RESULT is of any gas. To tie it up to our gas we need to look for its molecular weight:MW of CCL3F = 137.7 gm/mol. 

Then : 0.05x 137.5 = 6.88gm of vapor 

If we sustract the vapor weight from the TOTAL weight of liquid we have: 11.5gm - 6.88gm = 4.62 gm of liquid.d
