Answer:

The volume occupied by the air inside the hot balloon is 2.67 L.

Explanation:

Initial volume of the balloon =V_1= 2.50 L

Initial temperature of the air inside the balloon T_1= 22.0 °C = 295 K

Final volume of the balloon = V_2

Final temperature of the air inside the balloon =T_2= 43.0 °C = 316 K

Using Charles law:

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

V_2=\frac{V_1\times T_2}{T_1}=\frac{2.50 L\times 316 K}{295 K}=2.67 L

The volume occupied by the air inside the hot balloon is 2.67 L.

V1/T1= V2/T2   V =volume T= temp (in kelvin unit) 

2.5/(22+273)=V2/(43+273)

For the reaction: N2(g) + 2 O2(g) ⇌ 2 NO2(g), Kc = 8.3 × 10-10 at 25°C. What is the concentration of N2 gas at equilibrium when
KATRIN_1 [288]

Answer: Concentration of N₂ is 4.8.10^{9} M.

Explanation: K_{c} is a constant of equilibrium and it is dependent of the concentrations of the reactants and the products of a balanced reaction. For

N2(g) + 2 O2(g) ⇄ 2 NO2(g)

K_{c} = \frac{[NO2]^{2} }{[N2][O2]^{2} }

From the question concentration of NO2 is twice of O2:

[NO2] = 2[O2]

Substituting this into K_{c}:

K_{c} = \frac{[2O2]^{2} }{[N2][O2]^{2} }

8.3.10^{-10} = \frac{4O2^{2} }{[N2].O2^{2} }

[N2] = \frac{4O2^{2} }{8.3.10^{-10}.O2^{2}  }

[N2] = \frac{4}{8.3.10^{-10} }

[N2] = 4.8.10^{9}

The concentration of N2 in the equilibrium is [N2] = 4.8.10^{9}M.

How is phosphorylation of glyceraldehyde 3-phosphate in the payment phase of glycolysis different from phosphorylation of glucos
svet-max [94.6K]

In the preparatory phase of glycolysis, two molecules of ATP are invested and the hexose chain is cleaved into two triose phosphates. During this, the phosphorylation of glucose and its conversion to glyceraldehyde-3-phosphate take place.  During this phase, the conversion of glyceraldehyde-3-phosphate to pyruvate and the coupled formation of ATP take place. Because Glucose is split to yield two molecules of D-Glyceraldehyde-3-phosphate, each step in the payoff phase occurs twice per molecule of glucose.

Glyceraldehyde 3-phosphate dehydrogenase Simultaneous oxidation and phosphorylation of G3P produce 1,3-bisphosphoglycerate (1,3-BPG) and nicotine adenine dinucleotide (NADH).

The divalent cation also affected the response of the enzyme from the endosperm and shoots to adenine nucleotides and inorganic pyrophosphate.

This phase is also called the glucose activation phase. In the preparatory phase of glycolysis, two molecules of ATP are invested and the hexose chain is cleaved into two triose phosphates. During this, the phosphorylation of glucose and its conversion to glyceraldehyde-3-phosphate take place. Steps 1, 2, 3, 4, and 5 together are called the preparatory phase.

How many moles of oxygen are formed when 58.6 g of KNO3 decomposes according to the following reaction? 4 KNO3(s) → 2 K2O(s) + 2
Leya [2.2K]

Answer:

0.725 mol

Explanation:

Moles are calculated as the given mass divided by the molecular mass.

i.e. ,

moles = ( mass / molecular mass )

since,

mass of KNO₃ = 58.6 g  ( given )

Molecular mass of KNO₃ = 101 g / mol

Therefore,

moles of KNO₃ = 58.6 g / 101 g / mol

moles of KNO₃ = 0.58 mol

From the balanced reaction ,

4 KNO₃ (s) ---> 2K₂O (s) + 2N₂ (g) + 5O₂ (g)

By the decomposition of 4 mol of KNO₃ , 5 mol of O₂ are formed ,

hence, unitary method is used as,

1  mol of KNO₃  gives 5 / 4 mol O₂

Therefore,

0.58 mol of KNO₃ , gives , 5 / 4  * 0.58 mol of O₂

Solving,

0.58 mol of KNO₃ , gives , 0.725 mol of O₂

Therefore,

58.6g of KNO₃ gives 0.725 mol of O₂.

the element aluminum forms a cation with the charge fill in the blank 2 . the symbol for this ion is , and the name is fill in t
shtirl [24]

The element aluminum forms a cation with the charge of +3. The symbol for this ion is Al³⁺, and the name is aluminum ion. The number of electrons in this ion 10.

<h3>What are ions?</h3>

Ions are formed when an atom gains or loses electrons.

Metals form positive ions by a loss of electrons whereas non-metals form negative ions by gaining electrons.

The aluminum ion is formed when aluminum loses three electrons to form Al³⁺ ion which has 10 electrons.

in conclusion, ions are formed by a gain or loss of electrons.

Xenon forms several compounds with oxygen and fluorine. It is the most reactive non-radioactive noble gas because a. its large r
muminat

Answer:

d. its effective nuclear charge is lower than the other noble gases.

Explanation:

Xenon belongs to group O on the periodic table. Most of the elements here are unreactive.

Due to the large size of Xenon, the outermost electrons have very low effective nuclear charge. Effective nuclear charge is the effect of the positive charges of the nucleus on the electrons in orbits. This effect decreases outward as atomic shell increases.

Xenon has a very large atomic radius and there is weak a nuclear charge on the outermost electrons. The more electronegative elements would be able to attract some of its outermost electrons easily and form chemical bonds with xenon much more readily.
