What might happen if you mixed a strong acid with an equally strong base?
A.You would see an explosive chemical reaction.
B.The acid would destroy the base.
C.The base would destroy the acid.
D.You'd wind up with a pH-neutral salt and water.
Answer:
D
Explanation:
When you mix a strong acid and a strong base : ( D ) You will wind up with a pH-neutral salt and water
The mixture of a strong base and an equally strong acid results in a neutralization reaction, because at the point of equivalence the base and acid will completely neutralize each other.
The mixture solution will have a pH value of 7 and the end products will an ionic salt and water.
Hence we can conclude that When you mix a strong acid and a strong base , you will wind up with a pH-neutral salt and water.

In this periodic table, which type of element is shown in green boxes?
A. Noble gases
B. Metalloids
C. Nonmetals
D. Metals
The correct answer is B. Metalloids
Explanation:
In this periodic table, the green boxes include elements such as Boron (B), Arsenic (As), and Antimony (Sb). All these elements are known in chemistry as semimetals or metalloids. This classification is because these elements cannot be completely classified into metals or non-metals. Moreover, they all display similar properties including some level of conductivity, malleability, and solid-state. According to this, the correct answer is B.

What is the cost to drive to Los Angeles from San Francisco a distance of 405 miles if the cost of gasoline is $2.90 a gallon and the car get 25 miles per gallon of gas?
Answer: $46.98
Explanation:
The distance to drive to Los Angeles from San Francisco is 405 miles. Since the car get 25 miles per gallon of gas, for 405 miles, the car will use:
= 405/25 = 16.2 gallons
Since the cost of gasoline is $2.90 a gallon and the car will use 16.2 gallons. The cost will be:
= $2.90 × 16.2 gallons
= $46.98
1.) What is the molecular weight of the ketone shown below?
2.)Dry ice sublimes at −78.5 oC at a pressure of 1 atm. At room temperature and 1 atm pressure, what is happening to the dry ice molecules on a molecular level as sublimation occurs?
3.)For the pairs of molecules given below, list the intermolecular forces in each molecule. Also, give the types of electrostatic interactions that could occur between each pair of molecules
cyclohexane and CH2Cl2
CH3CH2OCH2CH3 and CH3CN
Answer:
See explanation
Explanation:
1. The Ketone was not sown in the question but i can give you a general idea of how to calculate its molecular weight. A ketone has a general molecular formula of CnH₂nO.
The molecular weight is calculated knowing that the relative atomic mass of carbon is 12, that of hydrogen is 1 while that of oxygen is 16.
Hence from the general molecular formula, the molecular weight of any ketone is calculated from; n(12) + 2n(1) + 16. Where n represents the number of atoms of each element in the ketone.
2. Sublimation of dry ice occurs when the molecules in dry ice absorb sufficient energy in the form of heat such that they now have enough energy for some molecules to overcome the inter molecular forces acting in the solid crystal and transform directly into the vapor phase. This process is endothermic.
3.
cyclohexane and CH2Cl2 molecules are held together by dispersion forces.
CH3CH2OCH2CH3 and CH3CN are polar molecules held together by dipole-dipole forces.

A
Matter consists of only large molecules.
B
Matter is made up of only charged particles.
C
The particles of matter have zero kinetic energy and potential energy.
D
The particles of matter are arranged in different ways for the different state.
Answer:
D .The particles of matter are arranged in different ways for the different state.
Explanation:
The kinetic molecular theory is used to explain the forces between molecules and the energy the molecules possesses.
One of the key postulate of this theory is that;
The particles of molecules are continual state of motion. They posses kinetic energy. In gas, the particles are random and moves in a straight line motion. Liquids are less random and only slide past one another. Solids have a restricted space and the molecules are free to move about.Therefore, we can see that the particles of matter are arranged in different ways for different state.

In the following reaction, how many grams of H2O are produced if 2.00 g of N2H4 react? N2H4 + 3 O2 ---> 2NO2 + 2H2O
Answer:
2
Explanation:
From this equation, 2 grams are produced.
The mass of H₂O produced from the reaction is 2.25 g
We'll begin by calculating the mass of N₂H₄ that reacted and the mass of H₂O produced from the balanced equation.
N₂H₄ + 3O₂ —> 2NO₂ + 2H₂O
Molar mass of N₂H₄ = (2×14) +(4×1) = 32 g/mol
Mass of N₂H₄ from the balanced equation = 1 × 32 = 32 g
Molar mass of H₂O = (2×1) + 16 = 18 g/mol
Mass of H₂O from the balanced equation = 2 × 18 = 36 g
SUMMARY
From the balanced equation above,
32 g of N₂H₄ reacted to produce 36 g of H₂O.
Finally, we shall determine the mass of H₂O produced by the reaction of 2 g of N₂H₄From the balanced equation above,
, 32 g of N₂H₄ reacted to produce 36 g of H₂O.
Therefore,
2 g of N₂H₄ will react to produce = (2 × 36) / 32 = 2.25 g of H₂O
Thus, the mass of H₂O produced from the reaction is 2.25 g
