Answer:

Plants wilt when the turgor turns to zero. From diminished water in cells. The rate of water being lost is greater then the water being absorbed.

Something like this. NOT EXACTLY THIS this is just an example.

I didn't know anything about this topic but I looked it up. For the other words I would look up the other words and see what they have to do with plants withering.

Think about a carbon atom that is released into the atmosphere from the burning of wood in a campfire. If it were to go through

viva [34]

1) Step 5 A tree absorbs the carbon from the atmosphere into its leaves for photosynthesis. Inorganic carbon is turned into organic.
2) Step 1 A caterpillar gets the carbon by eating the tree's leaves. Caterpillar use carbon for energy.
3) Step 3 A bird gets the carbon by eating the caterpillar. Organic carbon shifts from one animal to another
4) Step 4 The bird flies into a building and dies instantly. It falls to the ground.
5) Step 2 The bird decomposes and the carbon is added to the atmosphere. Organic carbon turns into inorganic.

A student finds a rock on the way to school. In the laboratory he determines that the volume of the rock by placing the rock in

9966 [12]

Answer:

1.76 g/mL

Explanation:

You need to find the volume. You can do this by subtracting the volume of the water and the rock by the volume of the water.

72.7 mL - 50 mL = 22.7 mL

Now that you have volume, divide the mass by the volume to find the density.

39.943 g/22.7 mL = 1.76 g/mL

A fishing line sinker contains 0.650 moles of lead. How many atoms of lead are in the sinker? Show all of your work, including s

34kurt

Answer:

3.91x10²³ atoms of lead

Explanation:

In chemistry, a mole of a substance is defined as 6.022x10²³ particles that could be atoms, molecules, ions, etc.

As you can see, in the problem, you have 0.650moles of lead in a fishing line sinker, the present atoms are:

$0.650mol Pb \frac{6.022x10^{23}atoms}{1mol}$ = 3.91x10²³ atoms of lead

Question 6: The Ideal Gas Law (7 points) a. What is the mathematical equation for the ideal gas law? Identify each variable and

azamat

The mathematical equation for the ideal gas law is PV = nRT.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

(A)

PV = nRT

The ideal gas equation is formulated as: PV = nRT. In this equation, P refers to the pressure of the ideal gas, V is the volume of the ideal gas, n is the total amount of ideal gas that is measured in terms of moles, R is the universal gas constant, and T is the temperature.

(B)

Where the pressure - P, is in atmospheres (atm) the volume - V, is in liters (L) the moles -n, are in moles (m) and Temperature -T is in Kelvin (K) as in all gas law calculations.

(C)

A. Boyle's law

B. Charles's law

C. Avogadro's law

D. Dalton's law

____ $- P_1V_1$ = $P_2 V_2$

____ $\frac{V}{T}$ = k

____ $\frac{V_1}{T_1}$ = $\frac{V_2}{T_2}$

____ V = kn

____ PV = k

____- P total = $P_1 + P_2 + P_3 + ...$

Boyle's law $- P_1V_1$ = $P_2 V_2$

Charles's law - $\frac{V}{T}$ = K

Charles's law - $\frac{V_1}{T_1}$ = $\frac{V_2}{T_2}$

Avogadro's law- V = kn

Boyle's law - PV = k

Dalton's law - P total = $P_1 + P_2 + P_3 + ...$

A scholar measures 20 mL of room temperature water (22ºC) and adds 80 mL of 75°C water to it, following the

Leni [432]

Answer:

Data is not valid

Explanation:

When two liquids having different temperatures are mixed, regardless of the volumes, the final mix temperature will ALWAYS be between the initial temperature values.

1st Law Thermo => Law of Conservation of Energy => Energy can not be created nor destroyed, only changed in form. Mixing 22°C with 75°C will NOT result in a mix having a final temperature of 80°C.

∑ΔE = 0 => (mcΔT)₁ + (mcΔT)₂ = 0

[(20g)(1cal/g·°C)(Tₓ - 22°C)] + [(80g)(1cal/g·°C)(Tₓ - 75°C)] = 0

=> 20(Tₓ - 22) + 80(Tₓ - 75) = 0

=> 20Tₓ - 440 + 80Tₓ - 75 = 0

=> 100Tₓ = 440 + 75 = 515

=> Tₓ = (515/100)°C = 51.5°C final mix temperature
