A farmer selectively breeds tomatoes to be shipped to grocery stores across the United States. Which of the following genetic traits would it be most important to selectively breed in the tomatoes?
A.The spoiling time of the tomatoes
B.The flavor of the tomatoes
C.The appearance of the tomatoes
D.The size of the tomato plants' leaves
Answer:
D
Explanation:
It would definitely affect size because breeding will change that trait
In selectively breeding tomatoes to be transported around the united states, one must consider the spoiling time of the tomatoes.
Tomatoes are vegetable fruits that are commonly consumed across the world and are very important because of their nutritive value. Often times, tomatoes are regarded as perishable goods because of their short shelf life.
In selectively breeding tomatoes to be transported around the united states, one must consider the spoiling time of the tomatoes.

a) How much energy would be required to melt 500 grams of ice at 0°C to water at 0°C?
Heat required = Q = 40 kcal
Further explanationGiven
mass of 500 g ice
Required
Heat required
Solution
The heat to change the phase can be formulated :
Q = m.Lf (melting/freezing) Q = m.Lv (vaporization/condensation)Lf=latent heat of fusion
Lv=latent heat of vaporization
Lf for water = 334 kj/kg=6.01 kJ/mol = 80 cal/g
Phase change(ice to water)
Q= 500 g x 80 cal/g
Q = 40 kcal
The theory of continental drift, a theory of a single, massive landmass that may have broken apart into what we associate with the modern landmasses and major continents was first supported by what significant evidence?
Answer:
So its a theory by Alfred Wegener is that All land was one big piece of land called pangea in the early 20th century people began to think that land masses can move such as many do just from it being there or natural disasters then going in to more research they found that when putting the continents together it fit like a puzzle and the fact that some fossils were far away from were the same were found
The theory of continental drift, based their theory on several lines of evidence, including the fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.
What does the continental drift theory?The continental drift hypothesis states that all the continents were once joined together as one large mass of land, but then the land spread apart and drifted into their current positions.
The hot magma flows in convection currents due to tremendous heat and pressure within the earth. These currents cause the tectonic plates that make up the earth's crust to move.
Thus, The theory of continental drift, based their theory on many lines of evidence, including the fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

Two gases are combined and sealed in a 2.0 L container. The 3.0 L of argon gas and 1.0 L of xenon gas each exert 1.00 atm pressure on the walls of their container.
(a) Calculate the partial pressure of each gas in the 2.0 L container.
(b) What is the total pressure in the 2.0 L container?
Answer:
Unless they chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each individual gas in a mixture exerts the same pressure that it would exert if it were present alone in the container . The pressure exerted by each individual gas in a mixture is called its partial pressure.

When 4.15 grams of silver nitrate is reacted with 1.11 grams of iron(III) chloride, which best represents the amount of silver chloride produced?
Answer:
The mass of silver chloride produced = 2.202 g
Explanation:
Equation of the reaction is given below
3AgNO₃(aq) + FeCl₃(aq) ----> 3AgCl(s) + Fe(NO₃)₃(aq)
molar mass of AgNO₃ = 170 g/mol
molar mass of FeCl₃ = 233.5 g/mol
molar mass of AgCl = 143.5 g/mol
3 moles of silver nitrate reacts with 1 mole of iron (iii) chloride to give 3 moles of silver nitrate
4.15 grams of AgNO₃ = 4.15/170 = 0.0244 moles of AgNO₃
1.11 grams of FeCl₃ = 1.11/233.5 = 0.0047 moles of FeCl₃
mole ratio of AgNO₃ to FeCl₃ = 0.0244/0.0047 = 5 : 1
therefore, FeCl₃ is the limiting reactant
0.0047 moles of FeCl₃ reacting will produce 0.0047 * 3 moles of AgCl = 0.0141 moles of AgCl
0.0141 moles of AgCl = 0.0141 * 143.5 g of AgCl = 2.02 g of AgCl =
Therefore mass of silver chloride produced = 2.202 g

What mass of aluminum is produced by the decomposition of 5.0 kg A l 2O 3? How many moles of oxygen are produced?
mass of Aluminum produced = = 2.647 kg
moles of Oxygen = 73.53 moles
Further explanationGiven
5.0 kg Al₂O₃
Required
moles of Oxygen
Solution
The aluminum oxide gets decompose into aluminum and oxygen gas.
Reaction :
2Al₂O₃(s)⇒ 4 Al(s) + 3O₂(g)
mol of Al₂O₃(MW=102 g/mol) :
= mass : MW
= 5000 g : 102 g/mol
= 49.02 moles
From the equation, mol ratio of Al₂O₃ : O₂ = 2 : 3, sol mol O₂ :
= 3/2 x mol Al₂O₃
= 3/2 x 49.02
= 73.53 moles
mol Al :
= 4/2 x mol Al₂O₃
= 2 x 49.02
= 98.04 moles
Mass Al :
= mol x Ar Al
= 98.04 x 27 g/mol
= 2647.08 g
= 2.647 kg

if you have 3g of sodium and 4g of chlorine what is the total mass of sodium chloride
Answer:
7g
Explanation:
Given parameters:
Mass of sodium = 3g
Mass of chlorine = 4g
Unknown:
Total mass of sodium chloride = ?
Solution:
This problem entails the direct application of the law of conservation of mass. According to this law, it states that "matter is neither created nor destroyed in the course of a chemical reaction".
So, when sodium and chlorine combines to form sodium chloride, to are expect to produce substance with a mass which adds up to the sum of the reactants;
Mass of sodium chloride = mass of sodium + mass of chlorine
= 3g + 4g
= 7g

Answer:
The number of moles of Sr in one mole of Sr(HCO₃)₂ = 1 mole
The number of moles of H in one mole of Sr(HCO₃)₂ = 2 moles
The number of moles of C in one mole of Sr(HCO₃)₂ = 2 moles
The number of moles of O in one mole of Sr(HCO₃)₂ = 6 moles
Explanation:
The given chemical formula of the compound is Sr(HCO₃)₂
The number of atoms of Sr in the compound = 1
The number of atoms of H in the compound = 2
The number of atoms of C in the compound = 2
The number of atoms of O in the compound = 6
The number of atoms of each element present in each formula unit of Sr(HCO₃)₂ is proportional to the number of moles of each atom in one mole of Sr(HCO₃)₂
Therefore;
The number of moles of Sr in one mole of Sr(HCO₃)₂ = 1 mole
The number of moles of H in one mole of Sr(HCO₃)₂ = 2 moles
The number of moles of C in one mole of Sr(HCO₃)₂ = 2 moles
