Answer: The hot dissolved butter will form softer cookies.

Explanation:

A) The final volume is V₂ = 14.86 L

B) The initial volume is V₁ = 490.5 mL

C) The final number of moles is n₂ = 0.0025

D) The initial moles is n₁ = 0.00088

Avogadro's law states that the total number of moles of a gas is directly proportional to the volume of the gas at a constant temperature and pressure.

Therefore, V ∝ n

or,  [tex]{\displaystyle {\frac{V_1}{n_1} =\frac{V_2}{n_2}[/tex]

Given the V₁ = 24.6 L, n₁ = 5.10 mol, n₂ = 3.09 mol

V₂ = V₁ n₂/V₁ = (24.7)(3.07)/5.10

V₂ = 14.86 L

V₂ = 419mL, n₁ = 1.07 mol, n₂ = 0.914 mol

V₁ = V₂ n₁/n₂ = (419)(1.07)/0.914

V₁ = 490.5 mL

Given the V₁ = 8.72 L, n₁ = 0.0020 mol, V₂ = 10.7 L

n₂ = V₂ n₁/V₁ = 10.7 ×0.0020/8.72

n₂ = 0.0025

Given the V₁ = 56 mL, V₂ = 17 mL, n₂ = 0.00268 mol

n₁ = n₂ V₁/V₂ = 0.000268 × 56/17

n₁ = 0.00088

It turns electrical energy into KE.

This is the correct statement of how a generator works:

A generator is described as a device that converts motive power or fuel-based power into electric power for use in an external circuit.

Generators contrary to general opinion do not create electricity instead it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit. This flow of electrons makes up  the output electric current supplied by the generator.

The present-day generators work on the principle of electromagnetic induction that was discovered by Michael Faraday.

Faraday realized that the above flow of current can be created by moving an electrical conductor in a magnetic field and this movement creates a voltage difference between the two ends of the conductor which causes the electric charges to flow, hence generating electric current.

Considering the Boyle's law, the volume of the gas sample will be 997.908 mL.

Boyle's law states that the pressure of a gas in a closed container is inversely proportional to the volume of the container, when the temperature is constant: if the pressure increases, the volume decreases while if the pressure decreases, the volume increases.

Mathematically, this law expresses that if the amount of gas and the temperature remain constant, the product of the pressure by the volume always has the same value:

P×V= k

where P is the pressure, V is the volume, and k is a constant.

Analyzing an initial state 1 and a final state 2, it is fulfilled:

P₁×V₁= P₂×V₂

In this case, you know:

P₁= 1.10 atm

V₁= 694 mL

P₂= 0.765 atm

V₂= ?

Replacing in Boyle's law:

1.10 atm× 694 mL= 0.765 atm×V₂

(1.10 atm× 694 mL)÷ 0.765 atm= V₂

997.908 mL= V₂

Most animals change due to the environment to help them live better

Cinder cones are made up of layers of pebble-sized or larger cinders and layers of ash. Larger volcanic bombs and blocks may also be present.

cinder cone, also called ash cone, deposit around a volcanic vent, formed by pyroclastic rock fragments (formed by volcanic or igneous action), or cinders, which accumulate and gradually build a conical hill with a bowl-shaped crater at the top. Cinder cones develop from explosive eruptions of mafic (heavy, dark ferromagnesian) and intermediate lavas and are often found along the flanks of shield volcanoes. The outside of the cone is often inclined at about 30°, the angle of repose (the slope at which the loose cinder can stand in equilibrium). Cinder cones may be only a few tens of feet high, or they may grow to a height of several hundred meters (several thousand feet), like that of Paricutín in Mexico. Lava flows may break out of or breach the cone, or they may flow from under the cone through tunnels. Cinder cones are numerous in nearly all volcanic districts. Although they are composed of loose or only moderately consolidated cinder, many of them are surprisingly enduring features of the landscape because rain falling on them sinks into the highly permeable cinder instead of running off down their slopes to erode them.

The volume of the sample after the reaction takes place at constant temperature and pressure would be 5.4 L.

In the reaction: [tex]N_2(g) + 2H_2(g)-- > N_2H_4(g)[/tex]

Stoichiometrically, 1 mole of [tex]N_2[/tex] reacts with 2 moles of [tex]H_2[/tex] to produce 1 mole of [tex]N_2H_4[/tex].

In reality, 0.1500 mol of  [tex]N_2[/tex] reacts with 0.3000 mol of [tex]H_2[/tex]. The equivalent amount of [tex]N_2H_4[/tex] that would be formed will be 0.1500 mol according to the mole ratios from the balanced equation of the reaction.

Now, at constant temperature and pressure:

0.1500 + 0.3000 = 0.4500 mol

0.4500 mol is equivalent to 16.2 L according to the illustration.

0.1500 mol of  [tex]N_2H_4[/tex] is produced, the equivalent mole would, therefore, be:

0.4500 mol = 16.2 L

0.1500 mol = 16.2 x 0.1500/0.4500
