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:
Because it'll live in the desert!
Explanation:
It probably won't survive on time!

If 3.91 moles of H2 were used, how many moles of NH3 would be made?
HELP PLEASE ASAP
N + H2 → NH3
balance the equation
2N + 3H2 → 2NH3
3H2 → 2NH3
3 : 2
3.91 ÷ 3 = 1.303 mol
1.3 × 2 = 2.606 mol
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.

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
When calcium chloride is added to a sample of water, the boiling point will _________. A. increase B. decrease C. not change D. first decrease, then increase
Answer:
C
Explanation:
If you add salt to water, its boiling point increases.
When calcium chloride is added to a sample of water, the boiling point will increase. Option A is correct.
What is boiling point?The boiling point of the liquid is the temperature at which the vapor pressure of a given liquid equals the external pressure or atmospheric pressure surrounding the given liquid.
The calcium chloride is added to a sample of water it releases the some amount heat and become exothermic and the boiling point will increase due to the reaction of water and calcium chloride.
Therefore, when calcium chloride is added to a sample of water, the boiling point will increase. Option A is correct.

2.00g of Copper wire was added to 50.0 mL of a 0.050M solution of Silver Nitrate. The reaction
produced solid silver and aqueous copper II Nitrate. The silver precipitate was collected and
dried. It was determined that the mass of the silver precipitate was 0.24 g. Use this information
to determine the theoretical yield, limiting reactant, and percent yield.
Answer:
See explanation
Explanation:
Now, the equation of the reaction is;
Cu(s) + 2AgNO3(aq) --------> Cu(NO3)3 (aq) + 2Ag(s)
Number of moles of silver precipitate = 0.24/108 g/mol= 0.0022 moles
Number of moles of AgNO3 = 50/1000 * 0.050 = 0.0025 Moles
If 2 moles of AgNO3 yields 2 moles of Ag
Then 0.0025 moles of AgNO3 yields 0.0025 * 2/2 = 0.0025 moles of Ag
Number of moles of Cu = 2.00g/63.5 g/mol = 0.03 moles
If 1 mole of Cu yields 2 moles of Ag
0.03 moles of Cu yields 0.03 moles * 2/1 = 0.06 moles of Ag
Hence AgNO3 is the limiting reactant
Theoretical yield of Ag = 0.0025 moles of Ag * 108 = 0.27 g
Actual yield of Ag = 0.24 g
Percent yield = actual yield/theoretical yield * 100
Percent yield = 0.24/0.27 * 100
Percent yield = 88.8%

In the given molecular formula of the aluminum sulphite which is Al2(SO3)3, this molecular formula there different type of elements are bonded together to form this compound each element has a specific number of atoms present. This compound has three elements that are aluminum, sulfur, and oxygen and the atoms are present are:
Al = 2 atoms represented by subscript
S = 3 atoms represented as whole subscripts of sulfite
O = 9 atoms 3 inside bracket and 3 outside of bracket that multiplies.
Thus, total number of atoms are 2+3+9 = 14
give an example of how an organism can use surface tension?
Answer:Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.
Explanation:
Answer:
Examples of surface tension Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight.

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.

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.

The measured pOH of a solution is 5.5. What is the hydrogen ion, [H+ ],
concentration?
First, calculate pH using the pOH:

[H+] = 10^-pH = 10^-9.5 = 3.2 x 10^-10 M ≈ 3 x 10^-10 M (The answer should technically only be one sig fig, since the pOH is given to only one decimal place).
