Which traits does the common garter snake have that might be adaptive for the environment where it lives?
Answer:
As the garter snake can be found almost in any kind of habitat, what makes them be able to survive in any environment include:
1. They hibernate to increase their chances of survival in unfavorable weather conditions.
2. They can blend with the background of any environment especially grass to escape being eaten.
3. They produce an odor that is usually unpleasant especially when about to be attacked.
Explanation:
The garter snakes are distinguished by the three stripes running the length of their body and can often be found in forests, places that are even close to water bodies, and almost any place, even in holes.
Answer:

How many nonbonding electrons are on each nitrogen atom?
A)
0
B)
2
c)
4
D)
6
4)
-))
Answer:
your answer is C
Explanation:
The electron-dot structure of NH3 places one set of nonbonding electrons in the valence shell of the nitrogen atom. that means there are three bonded atoms and one single pair for a coordination number of four surrounding the nitrogen, the same occurs in water to. along with the Lewis dot structure for ammonia, NH3. the non bonding atoms are basically like hydrogen atoms the try to refuse to bond and they can't be fused unless the right conditions are met.
Do you
think that the Nitrogen cycle has a negative or positive
impact on the environment?
Answer:
Nitrogen, the most abundant element in our atmosphere, is crucial to life. Nitrogen is found in soils and plants, in the water we drink, and in the air, we breathe. It is also essential to life: a key building block of DNA, which determines our genetics, is essential to plant growth, and therefore necessary for the food we grow. But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits. Farmers can add nitrogen fertilizer to produce better crops, but too much can hurt plants and animals, and pollute our aquatic systems. Understanding the Nitrogen Cycle—how nitrogen moves from the atmosphere to earth, through soils, and back to the atmosphere in an endless Cycle—can help us grow healthy crops and protect our environment.

Which is not a property of a gas? * exert pressure high density High compressibility readily soluble
Explanation:
A gas is state of matter in which there is large intermolecular distance and hence, a weaker molecular force of attraction in comparison to solids and liquids. therefore, it impart certain properties to gases which are uncommon in solids and liquids
Properties of a gas includes:
Exert pressure on the container
Highly compressible
Low density
and readily soluble in other mediums
Hence, high density is not a property of a gas.
What is the molar mass of a sample of gas that has a density of 2.85g/L at 101kPa pressure
and 29°C? Name the law that is used to solve this problem.
Answer:71.25
Explanation:
The molar mass of a sample of gas that has a density of 2.85g/L at 101 kPa pressure and 29°C is 71.37 g mol⁻¹ and It can be solved using Ideal gas law.
What is Ideal gas law ?The ideal gas law is an equation of state that describes ideal gases.
This equation of state relates a gas’s pressure, volume, temperature, and mass, and is very useful for describing how gases will behave in ideal conditions.
This is the most common equation of state for gases.
Ideal Gas equation ;
PV = nRT
Molar mass (Mm) = m /n
Where ;
m = given massn = number of moleswe also know,
Density (D) = m / v
Where ;
m = massv = volumeNow, Putting the formula of Molar mass and Density in ideal gas equation we get ;
Molar mass = D RT/ P
Given ;
Density = 2.85 g/LPressure = 101kpa (= 0.99 atm)Temperature = 29°C (= 302.15 K)(Gas constant) R = 0.0821Putting all the values in the above equation of molar mass ;
Molar mass = 2.85 x 0.0821 x 302 / 0.99
= 71.37 g mol⁻¹

Please give me brainleist. :)
Answer:
2a. If the temperature is increased, the reaction will shift to the right in an attempt to release some of the heat. As the forward reaction loses heat while the reverse would create more heat.
2b. If the pressure is increased, it would shift to the left to counteract the increase in pressure as the left side will have fewer molecules.
2c. If Cl2 is added the reaction will shift to the left in order to remove the stress of the extra Cl2 and favor the production of more reactant.
2d. If PCl3 is removed, the reaction will shift to the right. When part of the equation is removed the reaction learns to adapt to the loss by trying to make more Pcl3 and counteract the effects of losing the PCl3.
3a. The reaction will shift to the right to produce more heat and counter the negative effects of losing the heat.
3b. It will shift to the left to get rid of the excess HCl being produced and form more reactant from the breakdown of the HCl.
3c. It would shift to the right in order to get rid of the excess form products from it.
3d. If pressure is decreased there will be no effect on the shift of the reaction because there is an even amount of moles of gas on each side.
4a. K=[N2O4(g0] / [NO2(g)]2
4b. (Below)
K=[N2O4(g)] / [NO2(g)]2
0.4 / 0.5(2)
0.4/0.25 = 1.6
Keq= 1.6

PLZZZ HELP ME WITH THIS
Answer:
1) The mole ratio of KClO₃ to 3O₂ is 2:3
The reciprocal of the mole ratio of KClO₃ to 3O₂ is 3:2
2) The mole ratio of K to NaNO₃ is 1:1
The reciprocal of the mole ratio of K to NaNO₃ is 1:1
Explanation:
The mole ratio (also known as mole-mole ratio) of two compounds involved in a chemical reaction, is the ratio of the number of moles of the compounds in the reaction which can be obtained from the coefficients of the compounds in the balanced chemical reaction
The mole ratio of compound A to compound B = A:B = A/B
1)The given chemical reaction can be expressed as follows;
2KClO₃ → 2KCl + 3O₂
Therefore;
[tex]The \ mole \ ratio \ of \ KClO_3 \ to \ O_2 = \dfrac{2 \ moles \ of \ KClO_3}{3 \ moles \ of \ O_2} = \dfrac{2}{3} = 2:3[/tex]
[tex]The \ reciprocal \ of \ the \ mole \ ratio \ of \ KClO_3 \ to \ O_2 = \dfrac{3 \ moles \ of \ O_2}{2 \ moles \ of \ KClO_3} = \dfrac{3}{2} = 3:2[/tex]
2) In the reaction NaNO₃ + K → Na + KNO₃
The mole ratio of K to NaNO₃ = 1:1
Therefore;
The reciprocal of the mole ratio of K to NaNO₃ = 1:1

How do you find how many electrons are in a atom?
Answer:
To determine how many total electrons there are, add the amount of charge to the atomic number. In this case, there are fewer protons than electrons. For example, N 3- has a -3 charge which means it has 3 more electrons than a neutral nitrogen atom. Nitrogen’s atomic number is 7, therefore this ion has 10 electrons.

How many grams are in 1.5 moles of LiF?
solve for unknown
Answer:
The gram formula mass is the sum of the gram atomic masses of the atoms that make up a chemical formula. For lithium fluoride this works out to be 7g + 19g = 26g. Hence the mass of 1 mole of LiF is 26g; and the mass of 1.5 moles of LiF must be 1.5 × 26g = 39g.
