Answer:
Explanation:
Turgor pressure is the pressure forced or in other words, exerted onto the cell wall of the plant. It's caused by the movement of water into the cell. This causes the water to rush and burst into the cell, which increases the pressure onto the cell wall. Due to that, cell swells up, which helping the plant to stand upright and straight.
Hope this helps

The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.
What is a Chemical reaction?Chemical reaction refers to reaction that take place between reacting substances in which the chemical substances are transformed to products.
When the concentration of the reactants increases, more molecules tend to interact with each other in order to form new compounds, and the rate of reaction increases. When the concentration of the reactants reduces, there are little of that molecule present, and the rate of reaction decreases
Therefore, The statement that best explain which trial has a lower concentration of the reactants is Trial 1, because this reaction lasted for a longer duration than Trial 2.

2.31 M
B 0.248 M
C 0.142 M
D 24.1 M
can any one solve this quiz plz
Answer:
1. It is stoichiometric.
2. O2 is the limiting reactant.
3. 9.0 g of C2H6 remain unreacted.
4. 17.6 g of CO2.
5. 85.2%.
Explanation:
Hello there!
In this case, for the given chemical reaction:
[tex]2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O[/tex]
We can see that:
1. It is stoichiometric and is balanced because the reactants yields the products according to the law of conservation of mass.
2. In this part, it is possible to calculate the moles of ethane by using its molar mass:
[tex]n_{C_2H_6}=15g*\frac{1molC_2H_6}{30.08g} =0.50molC_2H_6[/tex]
And the moles of oxygen by knowing that one mole is contained in 22.4 L at STP:
[tex]n_{O_2}=\frac{1mol}{22.4L} *15.68L=0.7molO_2[/tex]
Thus, by calculating the moles of carbon dioxide product by each reactant, we can identify the limiting one:
[tex]n_{CO_2}^{by\ C_2H_6}=0.50molC_2H_6*\frac{4molCO_2}{2molC_2H_6} =1.0molCO_2\\\\n_{CO_2}^{by\ O_2}=0.70molO_2*\frac{4molCO_2}{7molO_2} =0.4molCO_2\\[/tex]
Thus, since oxygen yields the fewest moles of CO2 product, we infer it is the limiting reactant.
3. In this part, we calculate the mass of C2H6 that actually react first:
[tex]m_{C_2H_6}^{reacted}=0.4molCO_2*\frac{2molC_2H_6}{4molCO_2}*\frac{30.08gC_2H_6}{1molC_2H_6} =6.0gC_2H_6[/tex]
Thus, the leftover of ethane (C2H6) as the excess reactant is:
[tex]m_{C_2H_6 }^{leftover}=15g-6.0g=9.0g6.0C_2H_6[/tex]
4. Since 0.4 moles of carbon dioxide were produced, we use its molar mass to calculate the mass as its theoretical yield:
[tex]m_{O_2}^{theoretical}=0.4molCO_2*\frac{44gCO_2}{1molCO_2}=17.6gCO_2[/tex]
5. Finally, the percent yield is gotten by dividing the actual yield by the theoretical one:
[tex]Y=\frac{15g}{17.6}*100\%\\\\Y=85.2\%[/tex]

An electric car has a mass of 2,000 kg. the engine is producing a force of 3,500 N to move the vehicle forward,but it must overcome air friction equal to 500 N
What is the acceleration of the electric car m/s2?
record your answer and fill in below
Answer:
1.5 m/s²
Explanation:
From the diagram,
F-F' = ma............... Equation 1
Where F = Forward force of the vehicle, F' = Frictional force, m = mass of the electric car, a = acceleration of the car.
make a the subject of the equation
a = (F-F')/m........... Equation2
Given: F = 3500 N, F' = 500 N, m = 2000 kg
Substitute into equation 2
a = (3500-500)/2000
a = 3000/2000
a = 1.5 m/s²

37.2 moles of hydrogen gas would have what mass?
Your answer
Answer:
74.99g
Explanation:
Mass of a substance can be calculated by using the formula;
mole = mass ÷ molar mass
mass = molar mass × mole
According to this question, 37.2 moles of hydrogen gas is given.
Molar mass of hydrogen gas (H2) = 1.008(2) = 2.016g/mol
mass = 2.016 × 37.2
Mass of H2 = 74.995
Mass = 74.99g

What test would be done to prove the color of specific compounds is due to metal ions apart from flame test
Answer:
Borax bead test
Explanation:
Another test that can be used to identify colored ions in a specific compound such as salt is called "Borax bead test".
This test involves use of a clear glassy bead of borax that is joined together in a wire loop which is going to be involved in chemical reaction with the salts of certain metals.
This reaction will produce colors that we can use to identify the exact metal ions that are present.
Xavier was conducting a long term study of two populations of butterflies. Both populations had the same number of individuals. Both populations lived in forests that were the same size. Population A lived in a forest that was full of milkweed, the favorite food of this butterfly species. Population B lived in a forest that had limited amounts of milkweed and other foods. Over many years, Xavier found that one of the populations was showing signs of evolutionary change. Their mouth parts were changing and they could get food from new kinds of plants. Which statement explains why one population would be more likely to evolve in response to natural selection? *
a. Population B would be more likely to change because it has a ready supply of food, and only certain butterflies would be able to survive
b. Population A would be more likely to change because it has a ready supply of food and only certain butterflies would be able to survive
c. Population A would be more likely to change because it has a limited amount of food and some butterflies might be better able to get enough food, survive, and reproduce
d. Population B would be more likely to change because those butterflies have a limited supply of food, and butterflies with certain traits might be better able to get enough food, survive, and reproduce.
If a sulfur atom gained 3 protons what atom would be formed?
Answer:
The stable ion the sulfur would form is the sulfide ion,
Explanation:
When any atom accept electrons it converts into negative ion/an anion. So it will change into Z 3− after gaining 3 electrons.
Sulfur is an elemental atom that has an atomic number of 16 and an atomic mass of 32.065 amu. If the sulfur atom gains three protons then potassium will be formed.
What is a proton?A proton has been a sub-atomic particle that has been known to carry a positive charge and are tend to remain inside the nucleus with the neutrons bonded together by the nuclear force.
The proton of the atom is the characteristic property of the element in the periodic table. They are the sole sub-atomic particle that gives the atomic number of the elemental atom.
The sulfur atom has the atomic number 16 which means it has 16 protons, so if three protons are added to it then the number f protons become 19 which is an atomic number of the potassium (K) element.
Therefore, a potassium element is formed.

Why does water float on corn syrup
Answer:
density.
Explanation:
A cubic centimeter of water weighs 1 gram. Since a cubic centimeter of vegetable oil weighs less than 1 gram, oil will float on water. Corn syrup is more dense than water so 1 cubic centimeter of corn syrup weighs more than 1 gram. Therefore, corn syrup sinks in water.

How many grams of water, H 2 O , is given o when 62.1 g of propane, C 3 H 8 , burns?
Answer:
101.62 grams of water is given o when 62.1 g of propane burns.
Explanation:
Propane gas (C₃H₈) burns with oxygen gas and products carbon dioxide gas and liquid water. The balanced reaction is:
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O
By stoichiometry, the following amounts of moles of each compound participate in the reaction:
C₃H₈: 1 mole O₂: 5 moles CO₂: 3 moles H₂O: 4 molesBeing the molar mass of each compound:
C₃H₈: 44 g/mole O₂: 32 g/moleCO₂: 44 g/moleH₂O: 18 g/moleBy stoichiometry, the following mass quantities of each compound participate in the reaction:
C₃H₈: 1 mole* 44 g/mole= 44 grams O₂: 5 moles* 32 g/mole= 160 gramsCO₂: 3 moles* 44 g/mole= 132 gramsH₂O: 4 moles* 18 g/mole= 72 gramsThen you can apply the following rule of three: if by stoichiometry 44 grams of propane produces 72 grams of water, 62.1 grams of propane how much mass of water does it produce?
[tex]mass of water=\frac{62.1 grams of propane*72 grams of water}{44 grams of propane}[/tex]
mass of water= 101.62 grams
101.62 grams of water is given o when 62.1 g of propane burns.
