When 50.0 mL of 1.000 M HCl is reacted with 50.0 mL of 1.000 M NH4OH, the solution's temperature increases 8.65 °C. Calculate qsolution in units of kJ. The specific heat of the salt solution is 4.184 J/g-°C and the density is 1.010 g/mL.

Answers

Answer:

Explanation:

Total volume of solution = 100 mL .

Total mass of the solution = 100 x 1.01 g

= 101 g

specific heat of solution = 4.184 J/g-°C

rise in temperature = 8.65  °C

heat released = mass x specific heat x rise in temperature

= 101 x 4.184 x 8.65

= 3655.35 J

= 3.655 kJ .

qsolution = 3.655 kJ .

The following statement that it will provide information to help formulate a new hypothesis in the future is  true about a hypothesis that is proven to be inaccurate.

What is hypothesis?

Hypothesis can be defined as an assumption which is made for the sake of argument . It is an interpretation of a practical condition for which action needs to be taken.It is defined as a tentative assumption which is made to test logical consequences.It is an antecedent clause of a statement which is conditional.

It is constructed before research. There are six types of hypothesis 1)simple hypothesis 2) complex hypothesis 3) directional hypothesis 4)non-directional hypothesis 5) null hypothesis 6)casual hypothesis

The hypothesis should be clear and precise, it must be specific and way of explanation of hypothesis should be simple.

Why do electronegativity charts often give no values to the group 18 elements?

Answers

Answer:

Because they have complete electronic configuration

Explanation:

Group 18 elements are known as the noble or inert gases. The elements in this group are non-reactive because they have complete electronic shell configuration.

Electronegativity is the tendency of an atom to attract electrons. The reason why atoms attracts electrons is to have a stable configuration like those of the noble gases. Since the noble gases do not require any extra-electrons to attain stability, they have 0 electronegative values.

If I place a balloon in my fridge that initially has a pressure of 1.02 atm and a
temperature of 11.2 °C, what will be the pressure (in atm) of the balloon when it is
fully cooled to 4.00°C by my refrigerator?

Answers

Answer:

P₂ = 0.99 atm

Explanation:

Given data:

Initial pressure = 1.02 atm

Initial temperature = 11.2°C

Final pressure = ?

Final temperature = 4.00°C

Solution:

Initial temperature = 11.2°C (11.2+273 = 284.2 K)

Final temperature = 4.00°C (4.00+273 = 277 K)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

1.02 atm / 284.2 K = P₂/277 K

P₂ = 1.02 atm × 277 K / 284.2 K

P₂ = 282.54 atm. K /293 K

P₂ = 0.99 atm

Given the name of an element and the number of neutrons, find the mass of an Isotope

Answers

The given element nitrogen have 7 electrons and 7 protons. Mass number is the sum of number of protons and neutron. The number of neutrons is 7. Thus mass number of the isotope is  14.

What is nitrogen?

Nitrogen is 7th element in periodic table. It is an electronegative element and is included in p block. Nitrogen exists as gas but sometime it can be liquified under high pressure.

Isotopes are atoms with same atomic number and different mass number. Nitrogen have two isotopes. N-14 and N-15. Mass number is the sum of number of protons and neutrons.

Even though isotopes are different in mass number their chemical properties will be similar but there exists slight changes in their physical properties.

Here, we have 7 protons and 7 electrons therefore, the mass number 14.Thus the isotope given in the diagram is N-14.
