Answer:

92.37°C

Explanation:

Assuming the volume remains the same in both the states ( bicycle tire).

Then as per ideal gas equation

[tex]P_1/T_1 = P_2/T_2[/tex]

where P1, P2 are pressure at two different states and T1, T2 are temperature at these two states

Given:

P1 = 1.34 atm, T1 = 33.0 ° C = 306K

P2 = 1.60 atm, T2 = ?

1.34/306 = 1.60/T_2

⇒ T2 = 1.60×306/1.34

= T2= 365.37K= 92.37°C

FOr question 5, the answer is 80 gramas.

Explanation: According to the graph, when the salt is being dissolved in 100 ml of water at 90 degrees 40 grams had been dissolved. If you double the amount of water, the amount of solubility will also increase.

(Will come back later for edits)

According to the graph, when the salt is being dissolved in 100 ml of water at 90 degrees 40 grams had been dissolved. If you double the amount of water, the amount of solubility will also increase.

The graph shows the solubility curve of an unknown salt. The four points on the diagram represent four solutions of the unknown salt.The ratio of a constituent's abundance to the total volume of a mixture is called concentration. Mass concentration, molar concentration, number concentration, and volume concentration are four different categories of mathematical description.

Salt in freshwater is less than that in salt water, and the concentration of salt in the Dead Sea is greater than the concentration of salt in the oceans. The Dead Sea has a salinity of 33.7 percent, and the second-saltiest lake in the world is the Dead Sea.

Therefore, According to the graph, when the salt is being dissolved in 100 ml of water at 90 degrees 40 grams had been dissolved. If you double the amount of water, the amount of solubility will also increase.

Answer:

The temperature at 760mmHg if the volume is still 4.2 L is 400.862 K

Explanation:

Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law can be expressed mathematically as follows:

[tex]\frac{P}{T} =k[/tex]

Having an initial state 1 and a final state 2, the following is true:

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case:

Replacing:

[tex]\frac{560 mmHg}{295.372 K} =\frac{760 mmHg}{T2}[/tex]

Solving:

[tex]T2= 760 mmHg*\frac{295.372 K}{560 mmHg}[/tex]

T2= 400.862 K

Answer:

74.04 liters of hydrogen gas are produced.

Explanation: According to reaction, 2 mol of HCl gas gives 1 mole of hydrogen gas, then 6 moles of HCl gas will give: moles of hydrogen gas that is 3 moles.

The pressure of the hydrogen gas at 298 K = 0.990 atm

The volume occupied by the hydrogen gas = V

Number of hydrogen has moles = 3 moles

PV=nRT

V = 74.04 L

74.04 liters of hydrogen gas are produced.

Answer:

The hydrogens of the water molecules around the bromide ion will need to be faced toward it, whereas the oxygens of the water molecules around the potassium ion will need to be faced toward it.

The strength of the interaction within the compound will supersede that of the interaction between the compound and water.

Explanation:

To answer this question, you need to be aware of the structure of a water molecule and its components. A water molecule has the chemical formula of H2O, and oxygen is inherently electronegative, meaning that it attracts electrons very strongly. As a result, when it is in H2O, it pulls the valence electrons of the H atoms very strongly, which results  in the H atoms being partially positively charged and the O atom being partially negatively charged. Therefore, the O atom is going to be attracted to the potassium ion, whereas the H atom is going to be attracted to the bromide ion.

The answer to the second part of the question is as written above because ionic bonds are stronger than ion-dipole bonds; that's just the way it is.

Answer:

See explanation

Explanation:

The atomic number refers to the number of protons in the nucleus of an atom. We identify an element by its atomic number.

When the atomic number of an atom of an element is changed, we have changed the identity of that atom and transformed it into an atom of a different element.

For example, if we add a proton to a sodium atom, we create a magnesium atom. If we remove a proton from a sodium atom, we create a neon atom.

Answer:

1375 J/kg.°C

Explanation:

From the question First question,

Q = cm(Δt)................... Equation 1

Where Q = Heat released, c = specific heat capacity of the unknown metal, m = mass of the unknown metal, Δt = Change in temperature.

make c the subject of the equation

c = Q/mΔt.................. Equation 2

Given: Q = -5500 J (Since heat is released, Q is negative), m = 200 g = 0.2 kg, Δt = 10-30 = -20°C

Substitite these values into equation 2

c = -5500/[0.2×(-20)]

c = -5500/-4

c = 1375 J/kg.°C

Answer:

The answer is J (9.46 L)

The average speed of the food cart to the nearest tenth of a m/s is 0.3 meter per second.

Speed of any moving body will be calculated by using the below formula as:

Speed = Distance / Time

Given that, Distance travelled to the right side = 4.5m

Time to travel = 15 sec

On putting values on the above equation, we get

Speed = 4.5 / 15 = 0.3 m/s

Hence required speed is 0.3m/sec.

“Newton’s Law of Gravity” gives the gravity force between two objects with masses m

Let’s go back to the example given in the text: two 150 lb people separated by 1 meter.

The mass of each person is

Newton’s Law of Gravity actually gives the force only between two small objects. If one

of the objects is a sphere (such as the Earth) then it turns out that you can still use the

formula, but you must use the distance to the center of the sphere as the value for r. As

an example, let’s put in numbers for a 1 kg object sitting on the surface of the Earth.

Then the force of attraction is given by the gravity equation with m = 1 kg, M = the mass

of the Earth =

24 610

kg, and r = radius of the Earth (that’s the distance to the center of

the sphere). This distance is r = 6371 km ≈

meters. Without plugging in the

numbers, can you guess what the answer will turn out to be? Guess, and then check this

to see if you guessed correctly.

Suppose you weigh 150 lbs on the Earth. Then your mass is

you weigh on the Moon? We can calculate that by using Newton’s Law of Gravity, and

putting in the M = the mass of the Moon =

Answer:

96g of CO₂ would be produced

Explanation:

Based on the reaction:

CH₄ + 2O₂ → CO₂ + 2H₂O

1 moles of methane, CH₄ produces 1 mole of carbon dioxide, CO₂.

To solve this question we must find the moles of methane added in the reaction. These moles added are equal to moles of CO₂ produced. With the molar mass of CO₂ (44.01g/mol) we can find the grams that would be produced:

Moles CH₄ -Molar mass: 16.04g/mol-:

35g * (1mol / 16.04g) = 2.182 moles of CH₄ are added = Moles CO₂ produced.
