2C2H2(g) + 502(g) → 4C02(g) + 2H20(g) reaction type?

Answer:

2, 3, 4 I THIK

Explanation:

The true statement about is CO is likely to have different chemical properties than CaO.

Option (3) is correct.

In the given chemical reaction, Calcium oxide (CaO) reacts with carbon (C) to form calcium carbide (CaC₂) and carbon monoxide (CO). Let's analyze the chemical properties of CO and compare them with CaO, CaC₂, and C.

1. CO vs. CaO: Carbon monoxide (CO) is an entirely different compound from calcium oxide (CaO). CO is a colorless, odorless gas, while CaO is a solid compound. Their chemical properties will differ significantly.

2. CO vs. CaC₂: Carbon monoxide (CO) and calcium carbide (CaC₂) have distinct chemical properties. CaC₂ is a solid, and CO is a gas. Their reactivity, physical properties, and applications are dissimilar.

3. CO vs. C: Carbon monoxide (CO) and carbon (C) are related, but they are different chemical species. CO is an oxide of carbon, whereas C represents the pure element. Their bonding, reactivity, and uses are different.

Therefore, CO is likely to have different chemical properties than CaO, CaC₂, and C.

Answer:

Explanation:

Solution,

For Johnathan

Distance(d)=800m

Time(t)=200sec

Now,

Speed=d/t=800/200=4m/s

For Abby

Distance(d)=200m

Time(t)=40sec

Now,

Speed=d/t=200/40=5m/s

Here, Abby is faster by 1m/s.

Answer: An arbitrary rigid rotor is a 3-dimensional rigid object, such as a top

Explanation: The rigid rotor is a mechanical model of rotating systems. ... A special rigid rotor is a linear rotor requiring only two angles to describe, for example, a diatomic molecule. More general molecules are 3-dimensional, such as water (asymmetric rotor), ammonia (symmetric rotor), or methane (spherical rotor).

Hello!

Complete ionic equations separate the equations into ion forms. Weak electrolytes and solids (precipitate) are exempt from this rule.

Net ionic equations are complete ionic equations but the ions that don't form as a precipitate are left out of the equation.

Anything cancelled out from the complete ionic equations are considered the spectator ions.

Looking at the equation, there are no weak electrolytes (you might have not covered this material yet), and the only precipitate in the solution is [tex]V(OH)_3[/tex].

1. What is the complete ionic equation?

Let's ionize the equation. Make sure all the atoms are correspondent with their coefficients. Don't forget their charges.

[tex]3Li^+(aq)+3OH^-(aq)+V^3^+(aq)+3Cl^-(aq)= 3Li^+(aq)+3Cl^-(aq)+V(OH)_3(s)[/tex]

Label every ion as (aq), and check the periodic table for their charges. Even without looking for V, we know that it is a 3+ charge since there are 3 chlorines attached to it.

2. What is the net ionic equation?

Get rid of all of the ions that don't do anything. Consider them lazy if they don't precipitate or form a solid. In this case, anything other than V and OH should be removed since they don't react. Think of it as cancelling out the ions that are still ions both sides.

[tex]V^3^+(aq)+3OH^-(aq)=V(OH)_3(s)[/tex]

3. What are the spectator ions?

Spectator ions are the cancelled out ions from the previous problem.

[tex]3Li^+(aq)~, 3Cl^-(aq)[/tex]

Considering the Charles's Law, if you decrease the temperature of the gas by turning down the flame, the volume of the 400 L ballon decreases.

Charles's Law consists of the relationship between the volume and temperature of a certain amount of ideal gas, which is maintained at a constant pressure.

For a certain amount of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of movement of the gas molecules.

That is, the volume is directly proportional to the temperature of the gas.

In this case, taking into account the Charles's Law, at constant pressure, if you decrease the temperature of the gas by turning down the flame, the volume of the 400 L ballon decreases.

A bumper car stops moving when it strikes another car because : ( B ) Its energy is transferred to the other car

Following the law of conservation of energy, energy is neither destroyed or created but converted from one form to another. when the car collides with another car, the Kinetic energy possessed by the initial car will be transferred to the new car.

when a car possess potential energy the car will be at rest that is why the bumper car stops moving after collision

Hence we can conclude that A bumper car stops moving when it strikes another car because its energy is transferred to the other car.

Cassidee traveled a distance of approximately 2.24 miles. Her displacement was approximately 2.24 miles westward.

Cassidee's motion forms a right triangle. Her first leg is 1 mile north, and her second leg is 2 miles west. Using the Pythagorean theorem:

Distance = √(1 mile)² + (2 miles)²

Distance = √1 + 4 = √5 ≈ 2.24 miles.

For displacement, we consider her initial and final positions. The horizontal component (westward) is 2 miles, and the vertical component (northward) is 1 mile. Using the Pythagorean theorem:

Displacement = √(Horizontal)² + (Vertical)²

Displacement = √2² + 1²

Displacement ≈ √4 + 1 = √5 ≈ 2.24 miles.

However, displacement needs a direction. Since she moves west, displacement is -2 miles west.

In summary, Cassidee traveled a distance of approximately 2.24 miles. Her displacement was approximately 2.24 miles westward.

Answer: SiO2 has more electrons and stronger London dispersion forces.  

Answer:

9.46x10^12 kilomiters is your answer

Explanation:

Answer:

5.83g C4H10 x (1 mol C4H10/58.05 g (molar mass of C4H10) x (10 mol H2O/ 2 mol C4H10) x (18.002 g H2O (molar mass of H2O)/ 1 mol H2O=

Answer: 9.04 g of H2O

Explanation:

First set up equation: C4H10 (g)+ O2(g) -> CO2(g) + H2O(g)

Next balance it: 2C4H10 (g)+ 13O2(g) -> 8CO2(g) + 10H2O (g)

Use equation to get moles and plug given

5.83g C4H10 x (1 mol C4H10/58.05 g (molar mass of C4H10) x (10 mol H2O/ 2 mol C4H10) x (18.002 g H2O (molar mass of H2O)/ 1 mol H2O

Answer:

9.93712g

Explanation:

You have 10mL of water at 33 degrees, so you want to look at the density of water at 33 degrees. Then you multiply that density (.993712) by 10 and the mL cancel out and you are left with 9.93712g.
