Answer:

T₂ = 392 K

Explanation:

Given that,

Initial volume of the hot air balloon, V₁ = 55500 m³

Initial temperature, T₁ = 21°C = 294 K

Final volume, V₂ = 74000 m³

We need to find the final temperature inside the balloon. The relation between the temperature and volume is given by charles law i.e.

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}

Where

T₂ is the final temperature

So,

\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\\\\T_2=\dfrac{T_1V_2}{V_1}\\\\T_2=\dfrac{294\times 74000 }{55500 }\\\\T_2=392\ K

So, the new temperature is 392 K.

TMS has 12 protons which are all equivalent and four carbons, which are also all equivalent. This means that it gives a single, strong signal in the spectrum, which turns out to be outside the range of most other signals, especially from organic compounds.

Solve for y in the following problem: 5.3 x 10- (y)(2y)
weqwewe [10]

Answer:

The value of y = 5.1478

Explanation:

The linear equation is an equation obtained when a linear polynomial is equated to zero. When the solution obtained on solving the equation is substituted in the equation in place of the unknown, the equation gets satisfied.

The given equation: 5.3 x 10- (y)(2y) = 0

⇒ 53 - 2y² = 0

⇒ 2y² = 53

⇒ y² = 53 ÷ 2 = 26.5

⇒ y = √26.5 = 5.1478

Write the formula and calculate the molecular mass of
Reika [66]

The molecular formula is the sum of the atomic masses of all atoms in the molecule.

The formula of Soda Ash:

Na₂CO₃ is also known as Sodium Carbonate.

The molecular mass of Soda Ash is

(2×Na)+(1×C)+(3×O)=106g/mol

The formula of Baking Soda:

NaHCO₃ is also known as Sodium bicarbonate.

The molecular mass of Baking Soda is

(1×Na)+(1×H)+(1×C)+(3×O)=84g/mol

The formula of Lime Stone:

CaCO₃ is also known as Calcium carbonate.

The molecular mass of Lime Stone:

(1×Ca)+(1×H)+(1×C)+(3×O)=100g/mol

The formula of Ethanol:

C₂H₅OH is the formula of ethanol.

The molecular mass of Ethanol:

(2×C)+(6×H)+(1×O)=46g/mol

The formula of Common Salt:

NaCl is also known as Sodium chloride.

The molecular mass of Common Salt:

(1×Na)+(1×Cl)=58.5g/mol

Which chemical is the reducing agent in the redox reaction below?
posledela
Option (a) is correct.

A reducing agent is the one which loses electrons to other substance.

Here, Zn has oxidation number 0 in the L.H.S of the equation, but on R.H.S its oxidation number is +2 i.e. it Zn has donated two of its electrons to Fe^{2+}.

Hence, Zn is the reducing agent here.
