Please Help Me I Just Need The Answers Please No Need For The Explanation

Answer 1

Answer:

C = q / m x dT

Explanation:

By definition, specific heat, C = heat absorbed, q divided by mass, m and change in temperature, dT

So C = q / m x dT

Answer 2

Answer:

The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C)

Formula:

energy (J) = mass (kg) * specific heat capacity (J/kg°C ) * change in temperature

required answer:

C = q  / m * dT

using the formula:

C =   [tex]\frac{102}{12.5*(55-22)}[/tex]

C = 0.2473 J/kg°C

             ↑

This is the specific heat capacity of copper

Calcium-49, a radioactive isotope, has a half-life of 9 minutes. If an 80-gram sample of the isotope decays for 27 minutes, how many grams of the original sample remain?

Select one:
a. 60
b. 10
c. 40
d. 20​

Answers

Half-Life is the time required for half of the radioactive nuclei to decay to products.

In this case Calcium-49 has a half-life of 9 minutes and is allowed to decay for 27 minutes, meaning the sample experienced 3 half-lives.

80g of Calcium-49 allowed to decay for 9 minutes results in 40g of Calcium-49 (half-life 1)

40g of Calcium-49 allowed to decay for 9 minutes results in 20g of Calcium-49 (half-life 2)

20g of Calcium-49 allowed to decay for 9 minutes results in 10g of Calcium-49 (half-life 3)

b) 10g of Calcium-49 remains after 27 minutes of decay

According to the Law of Conservation of Matter, what happens to atoms of gas in a balloon when it is placed in the freezer?

the number of atoms stays the same and the energy stays the same, keeping the volume the same


the number of atoms stays the same as the atoms lose energy to the colder freezer, slow down, get closer together, shrinking the volume


the number of atoms increases, causing an increase in energy and an increase in volume


the number of atoms decreases, which takes up less space and decreases the volume

Answers

Answer:

the number of atoms stays the same as the atoms lose energy to the colder freezer, slow down, get closer together, shrinking the volume

Explanation:

When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid.

[WILL MARK BRAINLIEST!!] Describe the relationship between molecular structure and the strength of electrostatic
forces between molecules. How does this impact boiling and melting points?

Answers

Answer:

increase the bonding strength between two or more molecules

hope this help

Explanation:

Boiling points and melting points

The overarching principle involved is simple: the stronger the noncovalent interactions between molecules, the more energy that is required, in the form of heat, to break them apart. Higher melting and boiling points signify stronger noncovalent intermolecular forces.

The electron configuration of element Y ends in s?p4. What is
the symbol for the ion most commonly formed by this element?
a y2+
b y2-
с ү6+
d Y

Answers

This problem is providing us with the end of the electron configuration an element as s²p⁴ and asks for the most commonly formed ion. At the end, the answer is b Y²⁻.

Electron configuration

In chemistry, when analyzing electron configurations, one must first take into account how the energy levels must be filled with electrons.

Now, note the problem states that the electron configuration ends by s²p⁴, which means it is closer to complete the octet so it needs two electrons in order to do so, as it behaves as a nonmetal.

Therefore, the most commonly ion formed by this element is Y²⁻, because of the fact that it needs two electrons to complete the octet and thus become chemically stable and likely to bond with a metal.
