Answer:

Gravitational potential energy is one type of potential energy and is equal to the product of the object's mass (m), the acceleration caused by gravity (g), and the object's height (h) as distance from the surface of the ground (the body). In this example, a 3 kilogram mass, at a height of 5 meters, while acted on by Earth's gravity would have 147.15 Joules of potential energy, PE = 3kg * 9.81 m/s 2 * 5m = 147.15 J. The energy added to the system by the crane's swing is the gravitational potential energy gained by the change in the wrecking ball's height. We'll need to use trigonometry to determine the height based on the cable length and angle, calculate the potential energy gained, and convert it to kinetic energy.

In the Friedel-Crafts alkylation reaction, 1,4-dimethoxybenzene reacts with 3-methyl-2-butanol in the presence of H2SO4 and CH3COOH to yield the major product, which is 4-(3-methylbutyl)-1,4-dimethoxybenzene.

This reaction is an example of electrophilic aromatic substitution, where the alkyl group (3-methylbutyl) is substituted onto the aromatic ring (1,4-dimethoxybenzene). The H2SO4 serves as a catalyst to generate the electrophile (CH3C+(CH3)2CH2), which then attacks the aromatic ring. The CH3COOH acts as a solvent and helps to stabilize the intermediate formed in the reaction. It is important to note that the reaction may also produce minor products due to competing reactions, such as rearrangements and polyalkylations.

The net kinetic energy of the two curling stones is 160 J, and their net momentum is 0 kg·m/s.

The kinetic energy of an object is given by the formula KE = 1/2mv^2, where m is the mass of the object and v is its velocity. Since the two curling stones have the same mass and speed, their individual kinetic energies are given by:

KE1 = 1/2(20 kg)(4 m/s)²= 160 J

KE2 = 1/2(20 kg)(4 m/s)² = 160 J

The net kinetic energy of the two stones is simply the sum of their individual kinetic energies, which is:

KE net = KE1 + KE2 = 160 J + 160 J = 320 J

The momentum of an object is given by the formula p = mv, where m is the mass of the object and v is its velocity. Since the two curling stones are moving in opposite directions with the same speed, their individual momenta are equal in magnitude but opposite in direction.

Therefore, their net momentum is zero:

p1 = (20 kg)(4 m/s) = 80 kg·m/s (in the positive direction)

p2 = -(20 kg)(4 m/s) = -80 kg·m/s (in the negative direction)

p net = p1 + p2 = 0 kg·m/s

As a result, the two stones' net kinetic energy is 320 J, and their net momentum is 0 kgm/s.

Chlorine then has the eight electrons in its outer shell to make it "happy". Sodium is "happy" because it has now given up its one extra electron.

Answer:

speed inscreases mass decrreases, but when no friciton mass dont matter

Explanation:

Mass does not affect speed directly, but it does affect how fast an object can change its speed by accelerating or decelerating. Objects with larger masses require more time for acceleration or deceleration compared to lighter objects. The law of inertia states that objects that are still remain still and that objects in motion remain in motion regardless of the object's mass.

The theoretical yield of oxygen from the oxides present in a 1.00 kg sample of lunar soil will depend on the composition of the soil. However, we can make some assumptions based on the known composition of lunar soil.

Lunar soil is known to contain various oxides, including silicon dioxide (SiO2), aluminum oxide (Al2O3), iron oxide (FeO and Fe2O3), titanium dioxide (TiO2), and others. These oxides can be chemically processed to release oxygen gas.

The stoichiometry of the chemical reactions involved will depend on the specific oxides present in the soil. However, for the purposes of estimation, we can assume that all the oxides present in the soil are converted to their respective metals and oxygen gas.

For example, the reaction for the conversion of silicon dioxide to silicon metal and oxygen gas is:

SiO2(s) + 2 C(s) → Si(s) + 2 CO(g)

From this reaction, we can see that for every 1 mole of SiO2, 1 mole of oxygen gas is produced. The molar mass of SiO2 is 60.08 g/mol, so in a 1.00 kg sample of lunar soil, there are:

1000 g / 60.08 g/mol = 16.65 moles of SiO2

Therefore, the theoretical yield of oxygen gas from the SiO2 present in the soil is:

16.65 moles of O2 (since 1 mole of SiO2 produces 1 mole of O2)

Similarly, we can calculate the theoretical yield of oxygen gas from the other oxides present in the soil using their respective stoichiometric equations. Adding up the oxygen yields from each oxide will give us the total theoretical yield of oxygen from the soil.

Note that the actual yield of oxygen will likely be less than the theoretical yield due to inefficiencies and losses during the processing of the soil.

Hydroxyacetone

The concentration of hydronium ions at 100°C is 7.16 x 10⁻⁷ mol/L.

The ion product of water at 100°C is 5.13 x 10⁻¹³.

We can use this information to calculate the concentration of hydronium ions at this temperature. The ion product of water, or Kw, is defined as the product of the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in water. This relationship is expressed as follows:

Kw = [H+][OH-, ]At 100°C, Kw = 5.13 x 10⁻¹³. Since pure water is neutral, the concentration of hydrogen ions (H+) is equal to the concentration of hydroxide ions (OH-).

Therefore, we can write:[H+] = [OH-]

To solve for [H+], we need to take the square root of Kw:[H+] = √(Kw)[H+] = √(5.13 x 10^-13)[H+] = 7.16 x 10⁻⁷ mol/L

Therefore, the concentration of hydronium ions at 100°C is 7.16 x 10⁻⁷ mol/L.

Explanation:

Approximately 1052.63 kg of dry cellulose nitrate solution should be added to the 5.5% solution to meet the requirement of a 9.5% solution.

To determine how much dry cellulose nitrate solution should be added to the 5.5% solution to meet the requirement of a 9.5% solution, we can set up an equation based on the principle of mass balance.

Let's assume x represents the amount of dry cellulose nitrate solution (in kg) that needs to be added. The mass of cellulose nitrate in the dry solution is then 0.095x kg. The initial mass of cellulose nitrate in the 5.5% solution is 0.055 * 2500 kg = 137.5 kg.

When the dry solution is added, the total mass of cellulose nitrate becomes 0.095x + 137.5 kg. This mass should equal the desired amount of cellulose nitrate in the final solution, which is 0.095 * (2500 + x) kg.

Setting up the equation:

0.095x + 137.5 = 0.095 * (2500 + x)

Simplifying and solving for x:

0.095x + 137.5 = 237.5 + 0.095x

137.5 - 237.5 = 0.095x - 0.095x

-100 = -0.095x

x = -100 / -0.095

x ≈ 1052.63 kg
