Electronegativity is a chemical property which describes how well an atom can attract an electron to itself. Values for electronegativity run from 0 to 4. The difference in electronegativity (ΔEN) is used to predict whether a bond between atoms will be ionic or covalent. It can also be used to predict if the resulting molecule will be polar or nonpolar.
If a bond was made between the two atoms shown below, would the bond be (1) covalent, i.e. ΔEN = ≤ 0.4, (2) polar covalent i.e. ΔEN > 0.4 and ≤2.0, or (3) ionic, i.e. ΔEN > 2.0? Enter 1 for covalent, 2 for polar covalent, 3 for ionic.

A total solar eclipse occurs because the moon can totally block the sun. If the moon was smaller or farther from earth, a total eclipse
Could occur
Could not occur
Answer:
both
Explanation:
id say that it could occur but also not as much. the moon would be smaller and further from the earth to where we would barely be able to see it. if the full moon is barely visible then im sure the total solar eclipse wouldn't be as noticeable as it is now. but thats just my opinion

What indicates that two objects are in thermal equilibrium?
A The Objects Are the same size
B The objects Have the same temperature
C The objects are touching each other.
D The objects' temperatures are changing.
Answer:
B
Explanation:
equilibrium happens when two things are in complete balance and thermal is in reference to heat so two things are in thermal equilibrium once they have the same temperature.
The option which indicates that two objects are in thermal equilibrium is the objects that have the same temperature. Thus, the correct option for this question is B.
What is Thermal equilibrium?Thermal equilibrium may be defined as a state of a system in which all the parts of the system occupy the same temperature. Two or more objects are in thermal equilibrium if there is no net flow of thermal energy or heat between them when they are considerably connected by a path permeable to heat.
The mechanism of thermal equilibrium occurs when a cup of hot coffee is put on the table and after a short period of time, the temperature of the coffee is the same as the surrounding temperature. So, this represents an example of thermal equilibrium.
Therefore, the correct option for this question is B.

how many grams are present in 0.885 moles of manganese?
A. 48.6g
B. 62.1 g
C. 27.5 g
D. 0.016g
E. 21.5g
As per the details given, 48.6 g are present in 0.885 moles of manganese. The correct option is A.
To determine the gram contained in a given number of moles, use the element's molar mass. Manganese (Mn) has a molar mass of roughly 54.94 g/mol.
To calculate the grammes in 0.885 moles of manganese, use the following formula:
moles of Mn × molar mass of Mn = mass of Mn in grams
On calculating it:
0.885 moles × 54.94 g/mol = 48.60 g
Therefore, the mass of manganese present in 0.885 moles of manganese is 48.60 grams.
Thus, the correct answer is A. 48.6g.

3. Use the prefixes mono-, di-, tri-.... to indicate the number of that element in the molecule.
4. If mono is the first prefix, it is understood and not written
Answer:
Rules for naming simple covalent compounds:
1. Name the non-metal furthest to the left on the periodic table by its elemental name.
2. Name the other non-metal by its elemental name and an -ide ending.
3. Use the prefixes mono-, di-, tri-.... to indicate the number of that element in the molecule.
4. If mono is the first prefix, it is understood and not written
Examples:
N2O4 is called dinitrogen monoxideCO2 is called carbon dioxideCO is called carbon monoxideN2O is called dinitrogen monoxide. (It is also called nitrous oxide but that is another naming scheme.)CCl4 is called carbon tetrachlorideHere is a chart of those prefixes:

If you take 35 mL of solution from (#2c) and add 0.225 L of water what is the concentration of the resulting solution in (% v/v)? (hint: you must determine the final volume first)
HELP
We want to find the concentration of the resulting solution of mixing 35mL of a given solution and 0.225 L of water.
We will find that the concentration is 13.5%.
First, we need to write both of these in the same units.
We know that:
1000 mL = 1L
Then:
35 mL = 0.035 L
So when we mix the solution and the water we end with a total volume of:
V = 0.035L + 0.225L = 0.260L
The concentration of solution will be equal to the quotient between the volume of solution we used (0.035 L) and the total volume of the mixture (0.260L)
We will get:
Concentration = (0.035L)/(0.260L) = 0.135
Now to write it as a percentage, we only need to multiply this by 100%.
0.135*100% = 13.5%
This means that the mixture has a concentration of the 13.5%.

How do Hydrogen-1, Hydrogen-2, and Hydrogen-3 differ from each other?
Answer:
different from the number of their neutrons
Explanation:
They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ... Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.
