Answer:
IF(subscript 5)
Explanation:
covalent.
The bond present between the iodine and fluorine in iodine pentafluoride has been a nonpolar covalent bond.
The intermolecular bonds between the atoms result in the stability of the compounds. The bonds formed between the atoms with the same electrical charge and less difference in the electronegativity have been the nonpolar covalent bonds.
The iodine and fluorine have been the halogen atoms with a negative charge and less difference in electronegativity. Thus, the bond present between the iodine and fluorine in iodine pentafluoride has been a nonpolar covalent bond.

If a wave is traveling at a steady speed and its frequency is
doubled, what happens to the wavelength of that wave?
Answer:
If the frequency is doubled, the wavelength is only half as long.
Explanation:
Wave speed equals frequency*wavelength. So doubling the frequency must halve the wavelength in order for wave speed to remain the same.
In your own words, describe the purpose of using a chemical equation.
PLEASEEEE HURRY
Answer:
Hey mate, here is your answer. Hope it helps you.
Explanation:
To show how substances in a chemical reaction interact and to keep track of all elements and the number of atoms in each element on each side of the equation.The purpose of writing a balanced chemical equation is to know: the reactants (starting material) and products (end results) that occur. the ratios in which they react so you can calculate how much reactants you need and how much products can be formed.
Answer:
Sample Response: Chemical equations show how chemicals interact when a reaction occurs. They use symbols and formulas to show the chemical reaction so that chemical names do not need to be written out. They also help keep track of all elements and the number of atoms of each element on each side of the equation.

Explanation:
Calculate the mass of 120 cc of nitrogen at STP.How many
numbers of molecules are present in it?
2.67 × 10^19
Explaination:
The volume of the gas is 1c.c = 10^ - 3L
∴ Number of moles of the gas is=22.4 × 10^-3
Now,
Number of molecules = n × 6.022 × 10^23
∴ Number of Nitrogen Molecules
= 10^-3/22.4 × 6.023 × 10^23
= 2.67 × 10^19
Answer:
6.02 x 10²⁰ molecules
Explanation:
Given parameters:
Volume of nitrogen = 120cm³
Unknown:
Mass of Nitrogen = ?
Number of molecules present in it = ?
Solution:
At STP;
1 mole of a substance contains 22.4dm³ particles
100cm³ = 1dm³
24cm³ will give 0.024dm³
22.4dm³ of particles are in 1 mole of substances at STP
0.024dm³ of particles will contain [tex]\frac{0.024}{24}[/tex] = 0.001mole
Mass of Nitrogen = Number of moles x molar mass
molar mass of nitrogen = 14g/mol
Mass of nitrogen = 0.001 x 14 = 0.014g
Number of molecules present;
1 mole of a substance contains 6.02 x 10²³ molecules
0.001 mole of Nitrogen will contain 0.001 x 6.02 x 10²³ = 6.02 x 10²⁰
6.02 x 10²⁰ molecules

O A. A substance that has a much higher melting point and boiling
point than other similar substances
O B. A substance that is always in the solid or liquid phase at room
temperature
C. A substance that is in the gas phase at a temperature at which it
would normally be a solid or liquid
O D. A substance that forms a gas, but only at very high temperatures
Answer:
in physics, a vapor or vapour is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature. A vapor is different from an aerosol.

Which of the following has the largest electronegativity? AI, Cu, S, or O?
Answer:
O(Oxygen)
Explanation:
Oxygen or O among the given options has the highest electronegativity of 3.5 as compared to 2.4 of sulfur. Thus, there is a lesser attraction in the bonds of Sulfur. The other two elements Al(Aluminium) and Cu are less electronegative than Sulfur and Oxygen as they are metals and possess electropositivity while the latter displays more electronegativity due to being non-metals. Hence, Oxygen is the answer.
Which of the following covalent bonds is the strongest?
a)
quadruple covalent bond
b)
triple covalent bond
c)
double covalent bond
d)
single covalent bond
Answer:
a) quadruple covalent bond
Explanation:
Quadruple covalent bonds are the strongest covalent bonds. The more the number of bonding pairs, the stronger the bond becomes.
A covalent bond is formed by sharing of electrons between two species. They are usually between compound with similar electronegativities. The number of bonds between the atom determines the bond strength.Single < double < triple < quadruple covalent bonds.

How does the skin help regulate body temperature?
HELP FAST
Answer:
1. The body's immense blood supply (when blood vessels dilate or become larger heat loss occurs) When the blood vessels constrict it holds in heat
2. The skins blood supply also helps maintain body temperature (helps maintain homeostasis which is the "normal" state of our body)
3. Humidity in the air effects thermoregulation (heat regulation in the body) by limiting sweat evaporation (usually sweat evaporates into the environment when the humidity is low because the air has low "water levels" per say while you have high "water levels" because of your sweat

An element is determined by the number of
Answer:
The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus. The element oxygen has an atomic number Z=8, while carbon has Z=6.
Explanation:
Answer:
The number of protons determines which kind of element an atom is. If an atom has 8 protons, we can determine this element is oxygen.
Explanation:
In the nucleus of an atom, there are protons and neutrons. Protons have a positive charge and neutrons have a neutral charge. All atoms have at least one proton that determines its atomic number.
