Find the molar mass for NaNO3
Molar mass
= Atomic mass of Na + Atomic mass of N + Atomic mass of O3
= 23 + 14 + (16×3)
= 23 + 14 + 48
= 85 g per mole
Suzanne has a cat and uses a pet carrier to take her cat to the veterinarian. After a few years, the cat runs away and hides every time Suzanne gets the carrier out. Which best describes the cat's behavior? instinct reflex conditioned imprinting
Answer:
conditioned
Explanation:
The best term to describe the behavior of the cat is conditioned.
The cat has been conditioned to respond in a specific way to the pet carrier over time due to certain experiences - most likely, unpleasant ones. With repeated unpleasant experience associated with the per carrier, the cat has been conditioned to dislike/fear the pet carrier and thus, the recorded behavior.
Answer:
conditioned

The diagram below shows a longitudinal wave at one instant in its motion. Each oval represents a particle acted on by the energy of the wave as it moves from left to right.
Which line on the diagram indicates a region of rarefaction?
Answer:
Here now you can give the other person the brainly they deserve and they were right too :)
Explanation:
The line that has been the representation of the region of rarefaction in the diagram has been the line below the top line.
The diagram has been the representation of the movement of the particles under the influence of wave energy. The particles have been moving from left to right in the longitudinal order with a gain of energy.
The rarefaction has been the instance where the density of the waves has been lesser or where there has been one wavelength of the wave.
The diagram has been representing, at the line below the top arrow, there have been lesser density of the wave particles, thus, the region of rarefaction has been the instance in the lines below the top line.

A substance has a molecular formula of C8H10N4O2
The empirical formula of a substance = C₄H₅N₂O
Further explanationThe empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
((empirical formula)n=C₈H₁₀N₄O₂
divide by 2 :
(C₄H₅N₂O)₂=C₈H₁₀N₄O₂

If You are given 14 moles of C2H5OH(Ethanol) and 13 moles of O2( Oxygen), how
many moles of the limiting reactant is produce? C2H5OH + O2 -> CH3COOH +
H2O
Explanation:
1 ) first u have to balance the equation but in this case it is already balanced.
2) checking for the limiting reactant:
13 mol O2 × (1mol H2O / 1mol of O2) = 13 mol of H2O
14 mol of ethanol × (1mol H2O/ 1molof ethanol) = 14 mol of H2O
the less amount of moles produced from the O2 so the limiting reactant is oxygen
3) calculating the products moles
13 mol O2 × (1mol H2O / 1mol of O2) = 13 mol
13 mol O2 × (1mol Ch3Cooh / 1mol O2) = 13 mol
note: the ratios obtained from the balanced equation
4) the excess reagent is the ethanol 1 mol will be remain
The object will have a minimum gravitational potential energy at point

HELP ME PLEASE!! If given a graduated cylinder, a beaker with alcohol and a scale, explain the steps to find the mass of 40 mL of alcohol.
In general, some people equate mass and weight.
Mass is one of the principal quantities, which is related to the matter , whereas weight is a force that leads to the center of the earth (Earth's gravitational force)
Steps that can be taken to find the mass :
1. Weigh graduated cylinder (empty) 2. Pour the alcohol in the beaker into the graduated cylinder to the level of 40 ml 3. Weigh again graduated cylinder + poured alcohol 4. mass of alcohol 40 ml = mass in 3rd step - mass in the first stepperience

Explanation:
Why do electronegativity charts often give no values to the group 18 elements?
Answer:
Because they have complete electronic configuration
Explanation:
Group 18 elements are known as the noble or inert gases. The elements in this group are non-reactive because they have complete electronic shell configuration.
Electronegativity is the tendency of an atom to attract electrons. The reason why atoms attracts electrons is to have a stable configuration like those of the noble gases. Since the noble gases do not require any extra-electrons to attain stability, they have 0 electronegative values.What type of reaction would NI3+ ->lead to?
Answer:
Reduction potential (Eo) is defined as a tendency of a chemical species to be reduced by gaining an electron and is defined with electrochemical reference of hydrogen, which is globally given the reduction potential of zero [24].

Sodium metal reacts violently with water and chlorine is a toxic gas, yet we eat sodium chloride. Why is this possible? Select one: a. The properties of compounds are different from the properties of the elements that form the compounds.
b. The properties of compounds are identical to the properties of the elements that form the compounds, and we should not eat sodium chloride because it is toxic.
c. The physical properties of compounds are different from the physical properties of the elements that form the compounds, but the chemical properties of the elements and compound are the same.
d. The chemical properties of compounds are different from the chemical properties of the elements that form the compounds, but the physical properties of the elements and compound are the same.
Answer:
The properties of compounds are different from the properties of the elements that form the compounds.
Explanation:
When elements form compounds, their properties are significantly modified. The physical and chemical properties of compounds and that of the elements that compose them are significantly different.
The introduction of chemical bonds between different atoms in compounds make the compounds to differ from elements where the atoms are bonded to atoms of the same element.
How does the suns energy contribute to the movement of water in the water cycle?
Answer:Evaporation
Explanation:
The suns heat speeds the movement of water molecules, until the molecules move fast enough that they jolt out the surface of the water individually. Overtime the water gradually evaporates into water vapor.
