Explanation:
A physical change is easier / more difficult to reverse than a chemical change.
Answer:
the answer is that a physical change is easier to reverse then a chemical change.
Explanation: In order for a physical change to take place it's easier to just undo what happened then if it was a chemical change because in order for very few chemical changes to reverse to it's original substance you would need another chemical change.
Which has a smaller ionic radius than it's neutral atom?
A. Iodine
B.Cesium
C.Oxygen
D.Nitrogen
Explanation:
Caesium (Cs) has a smaller ionic radius than it's neutral atom.
because Caesium belong to Group 1 and It loses 1 electron. After losing 1 electron it gains 1 positive charge that's why caesium ionic radius become smaller as compared to neutral atom.
Therefore,
Option B is correct.

What is the conversion factor used when converting mass to moles?
In such a conversion, we use the molar mass of a substance as a factor to convert that to mole units into mass units (or, conversely, mass units into mole units).
Then We also established that 1 mol of Al incorporates a mass of 26.98 g (Example). Stated mathematically that is, 1 mol Al = 26.98 g Al
Molar massNow, This relation provides a factor to travel from grams to moles.
which is help to Using the factor 98.08 g / 1 mol: grams H 2 SO 4 = 3.60 Then mol x 98.08 g / 1 mol = 353 g H 2 SO 4

Mark is in charge of making change at his family's garage sale on a hot summer day. He runs low on change and brings out a jar of pennies from the house. He keeps the lid off of the jar. Later in the day, he notices that the pennies are hot. Which statement best explains what happened?\
Answer:
This question is incomplete
Explanation:
The question is incomplete without the options. However, when a metal (in this case what the pennies are made of) is left in direct contact with the heat from the sun, it conducts this heat and becomes hot. This process is called thermal conduction. The thermal energy is readily accepted by the material in which the pennies are made of thereby increasing the thermal energy of the penny coin which then makes the pennies hot after being left under the sun.

An atom with the electron configuration 2-8-8-2 has an incomplete
Answer:
3rd principal energy level
Explanation:
Principle energy that explains the energy of the electrons and positions of electrons of a particular atom. There are four energy levels fist to fourth that are made of sublevels and that is made up of s, p, d and f orbitals.
First principal energy level - 2
Second principal energy level - 8
Third principal energy level - 18
Fourth principal energy level - 32
3rd energy level has 9 orbitals, which has 18 electrons
2 in the s orbital,
6 in the three p orbitals, and
10 in the five d orbitals.
So, here there are only 8 electrons in the third principal energy level.

What is force and motion
Answer:
In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity (which includes beginning moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull.

Joyce poured 200 milliliters (mL) of water into a beaker, placed a thermometer in it, and heated it until it started to boil. She recorded a temperature of 100 degrees Celsius (°C) when it started to boil. She repeated the process with 400 mL of water. What would be the temperature when this second sample started to boil?
Answer:
100°C
Explanation:
The boiling point of water is 100°C and the difference is when will the water start boiling.

The heat required to raise the temperature of 12g of water from 16 C to 21 C is:
a) 60 J
b) 60 cal
c) 50 cal
d) 50 J
Answer:
The correct option is;
b) 60 cal
Explanation:
The mass of the given water, m = 12 g
The initial temperature of he given water = 16°C
The final temperature of the given water = 21°C
The specific heat capacity of water, c = 4.184 J/(g·°C) = 1 cal/(g·°C)
The amount of heat, ΔQ, required = Mass × Specific heat capacity × Change in temperature
ΔQ = 12 × 4.184 × (21 - 16) = 251.04 J
Similarly, we have;
ΔQ = 12 g × 1 cal/(g·°C) × (21 - 16)°C = 60 cal
The amount of heat required = 60 cal.

9A. A sample of hydrogen at 1.56 atm had it's pressure decreased to 0.73
atm producing a new volume of 751 mL. What was its original volume? *
Answer:
351.43mL
Explanation:
To calculate the original volume of hydrogen gas in this question, the Boyle's law equation will be used. Boyle's law equation is:
P1V1 = P2V2
Where; P1 = initial pressure
V1 = initial volume
P2 = final pressure
V2 = final volume
According to this question, the P1= 1.56atm, V1 = ?, P2 = 0.73atm, V2 = 751mL
Hence;
P1V1 = P2V2
1.56 × V1 = 0.73 × 751
1.56 V1 = 548.23
V1 = 548.23/1.56
V1 = 351.43mL
Therefore, the original volume of hydrogen gas is 351.43 mL.

What determines how many of each ion is required for an ionic compounds?
please do not look up on google!!!!
Each ion has a single charge, one positive and one negative, so we need only one ion of each to balance the overall charge. When writing the ionic formula, we follow two additional conventions: (1) write the formula for the cation first and the formula for the anion next, but (2) do not write the charges on the ions.
