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

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.

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:

Nitrites can be reduced to form nitrogen. Almost all nitrate salts are soluble in water. Almost nitrate are soluble in water and slightly soluble in primary alcohols. The oxidation number of nitrogen in the nitrates is +5. The oxidation number of nitrogen in nitrates is +3.

Explanation:

Ammonium nitrate readily dissolves in water by dissociating into its respective ions. This salt is acidic in nature. Ammonium nitrate is an important fertilizer required for the growth of plants.

The nitrogen is the most usually used limiting supplement in the development of crops. Nitrogen is essential for the vegetative development and it is involved in creating food through photosynthesis. The use of ammonium nitrate is the best way to provide nitrogen for the plants.

It is very essential to convert nitrogen into nitrate, in order to be used by the plants. The ammonium nitrate and nitrite are highly stable than urea and does not rapidly lose nitrogen to the atmosphere. So both the nitrites and nitrates of ammonium are soluble in water and plants can easily absorb them.

So ammonium nitrate has high nutrient content.

Answer:

53.9%

Explanation:

The equation of the reaction is;

C4H6O3+C7H6O3→C9H8O4+C2H4O2

Number of moles of salicyclic acid reacted = 88.3 g/138.121 g/mol = 0.639 moles

1 mole of salicyclic acid yields 1 mole of aspirin

0.639 moles of salicyclic acid also yields 0.639 moles of asprin

Theoretical yield of asprin = 0.639 moles * 180.158 g/mol

Theoretical yield of asprin = 115.12 g

Percent yield = Actual yield/Theoretical yield * 100/1

Percent yield = 62.0 g/115.12 g * 100

Percent yield = 53.9%

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.

Mass CO₂ produced.

2.182 moles CO₂ * (44.01g / mol) =

Explanation:

The molecular equation => F₂(g)  +  SrCl₂(aq) => SrF₂  + Cl₂(g)

Ionic Equation:  shows all species involved in the reaction. For the ionic reaction given the ionic equation should show all substances in reaction in ionic form along with the molecular formulas of non-ionic compounds. In general, salts that contain a metal and nonmetal that undergo ionization when dissolved in water.  

The ionic equation => Show ionic compounds in ionized form with oxidation states. Do not ionize weak acids weak bases ( molecular compounds.

=>  F₂(g) + Sr⁺² + 2Cl₋ => Sr⁺²(aq) + 2F⁻ +  Cl₂(g)

The net ionic equation =>  shows only species directly involved in the chemical process. If in the net ionic equation that are equivalent on both sides of the working equation, one should remove those compounds from the ionic equation showing only the species involved in the chemical reaction process.  

=>  F₂(g) + Sr⁺²(aq) + 2Cl⁻(aq) => Sr⁺²(aq) + 2F⁻(aq) +  Cl₂(g)

Note that Sr⁺²(aq) is found on the reactant and product sides of the equation. Cancelling Sr⁺² gives the net ionic equation.

=>   F₂(g) + 2Cl₋(aq) =>  2F⁻(aq) +  Cl₂(g)

Answer:

C

Explanation:

Carbon forms triple bonds will form triple bonds with other carbon and forms ethyne. The triple bonded hydrocarbons are commonly called as alkynes. Hence, option C ethyne is correct.

Carbon forms bond with other carbons and exhibit the property of catenation to form long chains. The backbone of hydrocarbons are the carbon - carbon bonds.

There are three types of hydrocarbons namely, alkanes, alkenes and alkynes. Alkanes are saturated hydrocarbon having single bond between carbon atoms. Eg. methane , ethane etc all having suffix of 'ane'. Alkenes are unsaturated hydrocarbons with double bond between two or more carbon atoms.

Alkenes are named with the suffix 'ene'. Hence, the names become ethene, propene etc. When triple bonds forms between carbon atoms they are called alkynes and are unsaturated. Alkynes are named with the suffix 'yne' like ethyne, propyne etc.. Hence, two carbon with triple bond between them is ethyne.

Explanation:

Answer: 100 torr

Explanation:

The total pressure exerted by a mixture containing two gases if the partial pressure of one gas is 70 torr and the partial pressure of the other gas is 30 torr is 100 torr. Therefore, option A is correct.

The total pressure of a gas mixture is the sum of its component gases' partial pressures: Ptot = Pi = P1 + P2 + P3... ntot = total number of moles in the gas mixture (the sum of all ni).

The sum of static pressure and velocity pressure is total pressure. Static pressure exists in a fluid that is not moving. The pressure required to accelerate air from zero velocity to a specific velocity proportional to the kinetic energy of the air stream is known as velocity pressure.

The total pressure is equal to the sum of partial pressure. Therefore, total pressure = 70 + 30

= 100 torr

Thus, the total pressure exerted by a mixture containing two gases is 100 torr.

Answer:

94 moles of Carbon

Explanation:

From the question,

Using Avogadro's constant

1  mole of every element contains 6.03×10²³ atoms of the element

If 1 mole of Carbon contains 6.03×10²³ atoms of Carbon,

Then, x mole of Carbon will contain 5.67×10²⁵ atoms of Carbon

1 mole of C ⇒ 6.03×10²³ atoms of C

x mole of C ⇒ 5.67×10²⁵ atoms of C

solve for x

x = (1× 5.67×10²⁵)/6.03×10²³

x = 94.03 moles of Carbon

x ≈ 94 moles of Carbon
