Answer: q = 64 kJ
Explanation:
As you know, a substance's specific heat tells you how much heat is required to increase the temperature of
1 g
of that sample by
1
∘
C
.
In water's case, you know that its specific heat is equal to
4.18
J
g
∘
C
. This tells you that in order to increase the temperature of
1 g
of water by
1
∘
C
, you need to supply
4.18 J
of heat.
How much heat would you need to increase the temperature of
200 g
of water by
1
∘
C
?
Well, if you need
4.18 J
per gram to increase its temperature by
1
∘
C
, it follows that you will need
200
times more heat to get this done.
Likewise, if you were to increase the temperature of
1 g
of water by
76
∘
C
, you'd need
76
times more heat than when increasing the temperature of
1 g
by
1
∘
C
.
Combine these two requirements and you get the total amount of heat required to increase the temperature of
200 g
of water by
76
∘
C
.
Mathematically, this is expressed using the following equation
q
=
m
⋅
c
⋅
Δ
T
, where
q
- heat absorbed/lost
m
- the mass of the sample
c
- the specific heat of the substance
Δ
T
- the change in temperature, defined as final temperature minus initial temperature
Plug in your values to get
q
=
200

Potassium iodide is an ionic compound.
Describe what happens, in terms of electron loss and gain, when a potassium atom reacts
with an iodine atom.
Answer:
In this reaction, potassium atoms lose electrons to form positively-charged potassium ions (oxidation) and iodine atoms gain electrons to form negatively-charged iodide ions (reduction).
Explanation:
pls mark as brainliest
In this process, iodine atoms get electrons to produce negatively charged iodide ions, whereas potassium atoms lose electrons to form positively charged potassium ions. Oxidation and reduction takes place.
What is oxidation ?Redox reactions include a change in the oxidation state of the substrate. Similar to how reduction is the acquisition of electrons while oxidation is the loss of electrons or an increase in the oxidation state.
An oxidation process takes place when oxygen interacts with a substance or an element. Another way to think of oxidation is as the process of removing hydrogen from the species of reactants. Molecule, atom, or ion oxidation is the process of losing electrons.
Because they generate new functional groups in molecules or alter existing functional groups, oxidation processes are crucial in the synthesis of organic substances.
Thus, the iodine atom also experiences a change. The iodide atom gets one electron during the reaction with potassium, leaving it with eight electrons at its outer energy level.

what happens when a liquid becomes a gas
Answer:
When a liquid changes to gas, the particles absorb heat energy and they start vibrating faster and distance between them increases. On constant vibration, intermolecular forces decrease and particles start moving away from each other and change to gas.

Which statement describes what a thermos does?
A. A thermos makes things warmer
B. A thermos stops heat transfer
C. A thermos makes things cooler
D. A thermos slows heat transfer
A thermos slows down the process of heat transfer as it minimizes the process of conduction and convection.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

What is the molarity of 930 mL of LiCl solution that contains 139.9 g of LiCI?
A. 3.5 mol/L
B. 150 mol/L
C. 3.3 mol/L
D. 3.5 x 10-3 mol/L
Explanation:
To determine the molarity, we have to find the number of moles in the volume given, and then extrapolate to find the number of moles that would be in 1 L.
Determine the moles in the given volume
moles of LiCl = mass ÷ molar mass
= 139.9 g ÷ 42.39 g/mol
= 3.30 mol
Find the moles in 1 L
Since 930 mL of LiCl = 3.30 mol
then 1000 mL of LiCl = (3.30 mol × 1000 mL/L) ÷ 930 mL
= 3.55 mol/L
how does electron-pair repulsion determine the molecular shape?
Answer:
The shape of a covalent molecule can be predicted using the Valence Shell Electron Pair Repulsion (VSEPR) theory. Very simply, VSEPR theory says that the valence electron pairs in a molecule will arrange themselves around the central atom (s) of the molecule so that the repulsion between their negative charges is as small as possible.
Explanation:
There are two types of chemical compound one is covalent compound and another is ionic compound in chemistry. In ionic bonds, electrons are completely transferred. Electron-pair repulsion play an important role in determining the molecular shape using VSEPR theory.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
The shape of a covalent molecule can be predicted using the Valence Shell Electron Pair Repulsion (VSEPR) theory. VSEPR theory says that the valence electron pairs in a molecule will arrange themselves around the central atom (s) of the molecule so that the repulsion between their negative charges is as small as possible.
Therefore, electron-pair repulsion play an important role in determining the molecular shape using VSEPR theory.
