What is the atomic mass, in amu, of this atom?

Answer:

TiCl₄

Explanation:

From the law of conservation of mass, the mass of the reactants must equal the mass of the products. In other words:

[tex]\displaystyle \text{m Cl$_2$} + \text{ m Ti} = \text{ m Ti$_x$Cl$_y$}[/tex]

Find the mass of chlorine gas reacted:

[tex]\displaystyle \begin{aligned} \text{ m Cl$_2$} + (0.532 \text{ g}) & = (2.108 \text{ g)} \\ \\ \text{m Cl$_2$} & = 1.576 \text{ g} \end{aligned}[/tex]

Find the number of moles of each reactant using their respective molecular weights:

[tex]\displaystyle 1.576 \text{ g Cl$_2$} \cdot \frac{1 \text{ mol Cl$_2$}}{70.90\text{ g Cl$_2$}} \cdot \frac{2\text{ mol Cl}}{1\text{ mol Cl$_2$}} = 0.04446\text{ mol Cl}[/tex]

And:

[tex]\displaystyle 0.532\text{ Ti} \cdot \frac{1\text{ mol Ti}}{47.87\text{ g Ti}} = 0.0111\text{ mol Ti}[/tex]

To find the empirical formula, all values by the smallest value:

[tex]\displaystyle \begin{aligned} \frac{0.0111\text{ mol Ti}}{0.0111} & = \frac{0.04446\text{ mol Cl}}{0.0111} \\ \\ 1\text{ mol Ti} & \approx 4\text{ mol Cl}\end{aligned}[/tex]

Hence, there are four moles of chlorine for every one mole of titanium.

In conclusion, our empirical formula is TiCl₄.

The atomic number on the Periodic Table will tell you how many protons are in the nucleus of each atom.

Explanation:

number of electrons and protons should be equal in a neutral atom. Because each electron has a -1 charge, and each proton a +1 charge, the number of each must be the same for the net charge to equal zero.

Answer:  the answer is C. The warmer object's particles speed up

the cooler object's particles.

Explanation:    Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. This then continues and passes the energy from the hot end down to the colder end of the substance.

Answer:

M-A=N

Explanation:

M-A=N

Here is an example.

The equation above means that the atomic number (A) subtracted from the average atomic mass (M) equals the combined amount of neutrons and protons. Since we know that 35 17Cl is Chlorine (this is because Chlorine (Cl) is the 17th number on the periodic table and has the average atomic mass of 35), we can insert our data into the equation and end up with the following:

35-17=18.

From here, we can tell that we have a mix of neutrons and protons, with the total being 18. Since the atomic number is 17, we can reasonably assume that there are 17 protons and 1 neutron.

But we still need to find the number of electrons. Fortunately, the number of electrons is always equivilant to the number of protons and the atomic mass, so we know that the number of electrons is 17.

So, we have;

17 Protons

1 Neutron

17 Electrons

On the periodic table, hydrogen and helium are the only two elements in the first row, or period, which reflects that they only have electrons in their first shell. Hydrogen and helium are the only two elements that have electrons exclusively in the 1 s 1s 1s orbital in their neutral, non-charged, state.

Answer:

Arrange them in order of greatest to least Molar Mass to get most dense to least dense at a given temperature and pressure.

Explanation:

"Given Temperature and Pressure" just tells you that those two variables are being held constant. The Ideal Gas Law (PV = nRT) shows that n (the # of moles) and V (the volume) are variable still. To keep pressure constant, we need to increase the volume so that the force per area is the same which would unfortunately lower the density. The only way for a gas to have the greatest density would be to have the least average kinetic energy to keep the pressure constant at a smaller volume. This is because kinetic energy is equal to KE = 1/2 m v^2, where m is mass in kilograms and v is the velocity. IT IS CRUCIAL TO NOTE THAT ACCORDING TO KINETIC MOLECULAR THEORY, ALL GASES HAVE THE SAME AVG. KINETIC ENERGY WHEN AT THE SAME TEMPERATURE. So since the avg. KE is also constant across these answers due to the temp. being constant, our only way to decrease the velocity (the rate at which the particles are moving per second) and in turn the number of collisions (to repeat, a smaller number of collisions is desired because they are equal to the pressure that must maintained at a constant value at the smallest volume possible to achieve highest density possible) is to increase the molar mass. This is also pretty intutive for the other part of the issue: since Density is a broken heart (m/v), a higher molar mass would ensure a smaller pressure (due to decreased velocity) and smaller volume (due to constant pressure). Okay, now order the gases heaviest to lightest in terms of molar mass and you got your answer. Please gimme brainliest if this helped bc it took 15 minutes to type out. Hope this helped you! :D

Density is an intensive property as it does not depend on the quantity of the substances Whereas mass and volume are extensive property. The order of density is carbon dioxide>Neon >argon>carbon-12> hydrogen.

Density tells about the compactness of the substances, how much dense is the substances in other words. Object that is more denser than water they just sink in the water.

Mathematically,

Density of gas  = Molar Mass of the gas  ÷volume occupied by the given gases

Density is directly proportional to molar mass of the gases.

Molar mass of argon = 18g/mole

Molar mass of Neon = 20g/mole

Molar mass of carbon dioxide=44.01 g/mol

Molar mass of hydrogen=1g/mol

Molar mass of carbon-12=12g/mol

The order of gases from most dense to least dense at a given temperature and pressure is carbon dioxide>Neon >argon>carbon-12> hydrogen.

Therefore, the order of density is  carbon dioxide>Neon >argon>carbon-12> hydrogen.

Answer:

Even though the two substances possess many similarities, they have some unique properties. In turn, since they have the same properties, if they were the same substance, it would make matters worse, if the same chemical was in two different places, there would not be a difference between them since they are the same, just as it is with are two different chemicals would have differing properties since they are two properties would vary from one another since they are 2 totally different things!

The mass of Fe produced from the reaction is 0.938 g.

We'll begin by calculating the mass of Fe2O3 that reacted and the mass of Fe produced from the balanced equation.

3Zn + Fe₂O₃ —> 2Fe + 3ZnO

Molar mass of Fe₂O₃ = (56×2) + (16×3) = 160 g/mol

Mass of Fe₂O₃ from the balanced equation = 1 × 160 = 160 g

Molar mass of Fe = 56 g/mol

Mass of Fe from the balanced equation = 2 × 56 = 112 g

From the balanced equation above,

160 g of Fe₂O₃ reacted to produce 112 g of Fe.

Finally, we shall determine the mass of the Fe produced by 1.34 g of Fe₂O₃

From the balanced equation above,

160 g of Fe₂O₃ reacted to produce 112 g of Fe

Therefore,

1.34 g of Fe₂O₃ will react to produce = (1.34 × 112)/160 = 0.938 g of Fe

Thus, 0.938 g of Fe was produced from the reaction.

Answer:

The graph represents an endothermic reaction.

The products have more energy than the reactants.

80kJ

160kJ

80kJ

160kJ

The given graph is representing an endothermic reaction as the potential energy reactants are lower than that of the products.

ΔH of the reaction and activation energy is 80 KJ and 160 KJ respectively.

An endothermic process can be defined as a process with an increase in the enthalpy H of the system. An endothermic process involves an increase in the temperature of the system.

Whether a process occurs spontaneously depends not just on the enthalpy change but also on the entropy change and temperature.

From the graph, the potential energy of the reactants = 80 KJ

The potential energy of the products = 160 KJ

ΔH of the reaction, ΔH = PE(products) - PE(reactants)

ΔH = 160 -80 = 80 KJ

The activation energy (Ea) of this reaction will be:

Activation Energy (Ea) = Maximum Energy - PE(reactants)

Activation Energy = 240 - 80 = 160 KJ

This problem is providing information about the equilibrium reaction whereby nitrogen dioxide gas produced dinitrogen tetroxide gas as shown on the attached picture and the following chemical equation:

NO₂ (g)  ⇄ N₂O₄ (g)

In such a way, we can consider the given choices to reason the following:  the blue arrow is pointing out the arrival to the equilibrium condition for the reaction, a point in which the rate of the forward reaction (formation of N₂O₄) is equal to the rate of the reverse reaction (formation of NO₂), because the molecules will fluctuate to the same relative amounts defined by the equilibrium constant.

Therefore the answer will be the first one on the attached file, which can vary on your online homework format.

It is important to note that the reactant is not used up at any point of the graph (concentration drops to 0) and also, the activation energy cannot be analyzed with this sparse information.
