The reaction between NaOH(aq) and H2SO4(aq) was studied in a constant-pressure calorimeter: 100.0 mL portions of 1.00 M aqueous NaOH and H2SO4, each at 24.0C, were mixed. The volume of the mixture was 200.0 mL. The maximum temperature achieved was 30.6C. Neglect the heat capacity of the calorimeter and the thermometer, and assume that the solution of products has a density of 1.00 g/mL and a specific heat capacity of 4.18 J/(g·K). Calculate H, the heat (enthalpy) of reaction, in kJ per mole of acid. (Hint: You may not have the equivalent amounts of NaOH and H2SO4 in this experiment.)

What two-step process separated the cans into aluminum, steel, and tin?

Answers

Answer:

Magnet

Durability and heaviness.(texture)

Explanation:

Magnet can be use to separate Aluminum from mixture of steel and aluminum.

Though aluminum and steel look alike but magnet can be use to separate it.

If the can attract the magnet or magnet stick to the can, it is a steel can. Aluminum does not stick to magnet.

A mixture of Aluminum and tin can also be separated by magnet.

Tin attract magnet but tin is more durable, heavy and does not corrode easily.

When u touch the three cans, tin is heavy and durable.

Help please! :)Why are prefixes not needed in naming ionic compounds?
A. lon charges are written as superscripts with the names of the
atoms.
B. Roman numerals are used instead of prefixes to indicate number.
C. Subscripts are used in the name to indicate number of atoms.
D. Ions combine in only one ratio.

Answers

Prefixes are not used to indicate the number of atoms when writing the chemical formula. The number of atoms are written as subscripts to their chemical symbols.

What is chemical formula?

Chemical formula of a compound is used to identify a compound and distinguishes it from other compounds. A chemical formula is written from the chemical symbols of elements which constitute the compound.

The number of atoms of each element is written as the subscripts of the symbols for each atoms. For example,magnesium chloride contains one magnesium and two chlorine atoms thus, its formula is MgCl₂.

The subscripts for each atom in the formula of an ionic compound is the charge of the other atom into which it is bonded. Similarly, the formula of iron oxide containing 2 Fe and 3 O is written as Fe₂O₃.

What is the IUPAC name for the compound FeS?

Answers

The IUPAC name for the compound FeS is Iron(II)Sulfide. IUPAC stands for International Union of Pure and Applied Chemistry. This is an organization that establishes official names of chemical elements and compounds. Hope this is the answer that you are looking for.

Answer:

The correct answer is “Iron(II) sulfide.”

Explanation:

It is pretty obvious there is presented an iconic compound made by iron written as Fe and a sulfur, S that is a nonmental instead. A metal as iron will form a cation and a nonmetal an anion. The sulfur will need 2 electrons from iron in order to complete its octet and in this way the iron equilibrates the sulfur. It can give it 2, so that is why we write it in Roman numbers, and form the formula above.

When a liquid is cooled, the kinetic energy if the particles A. Decrease B. Increases C. Remains the same. The force of attraction between the particles A. Decrease B. Increases C. Remains the same , the space between the particles A. Decrease B. Increases C. Remains the same

Answers

Answer:

(A.) Kinetic energy decreases
(B.) Force of attraction increases
(C.) Space between particles remains the same

Explanation:

Kinetic energy is the energy in motion. Cooling if liquid would cause decreased temperature and hence slow down the oscillation of the particles.

Likewise, increased heat reduces the force of attraction between said particles, which allowed for their free movement. So the cooling would have opposite effect.

Finally, the space between the particles would remain the same as it was originally, as their force of attraction is increased in the cooling process, they would take the form they are held in.
