Answer:

A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. Salts are also formed in this reaction.

Explanation:

The new pressure : P₂ = 1038.39 mmHg

Given

1.5 L container at STP

Heated to 100 °C

Required

The new pressure

Solution

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure).

So P₁ =  1 atm = 760 mmHg

T₁ = 273 K

T₂ = 100 °C+273 = 373 K

Gay Lussac's Law  

When the volume is not changed, the gas pressure is proportional to its absolute temperature  

[tex]\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]

Input the value :

P₂=(P₁.T₂)/T₁

P₂=(760 x 373)/273

P₂ = 1038.39 mmHg

Answer:

Neon (Ne)

Explanation:

Nitrogen in it's neutral state has valency of 5 and it's electronic configuration is  given as;

1s2 2s2 2p3

However in isocyanic acid, it forms a covalent bond with hydrogen and carbon. Due to this bond, it is able to achieve stable octet configuration. The configuration is given as;

1s2 2s2 2p6

This is the same electronic configuration as Neon

Answer:

white

Explanation:

A white precipitate of barium sulfate forms if sulfate ions are present. The hydrochloric acid is added first to remove any carbonate ions that might be present - they would also produce a white precipitate, giving a false positive result. Barium nitrate solution can be used instead of barium chloride solution

The balanced chemical equation is  [tex]\rm C_3H_8 + 5O_2- \rightarrow 3CO_2 + 4H_2O[/tex].

Chemical equation is defined as a formulation of mathematics that captures the chemical reaction. We can learn about the reactants and products involved in a chemical reaction by developing a chemical equation. It includes the symbols for the atoms of each element found in the compound, together with a count of how many of each element there are overall in the form of subscripts.

Chemical equations must be balanced in order to satisfy the law of conservation of mass, which states that "the total mass of all products of reaction in a chemical reaction is equal to the total mass of all reactants." A chemical equation is said to be balanced when the number of various elemental atoms on the reactants and products sides are equal. Chemical equations must be balanced by a process of trial and error.

Thus, the balanced chemical equation is [tex]\rm C_3H_8 + 5O_2- \rightarrow 3CO_2 + 4H_2O[/tex].

The given question is incomplete. The complete question is:

How much heat is produced when 24.8 g of [tex]CH_4[/tex] is burned in excess oxygen gas

Given: [tex]CH _4 +2O_2\rightarrow CO_2+2H_2O[/tex]  ΔH= −802 kJ.

Answer: 1243.1 kJ

Explanation:

Heat of combustion is the amount of heat released on complete combustion of 1 mole of substance.

Given :

Amount of heat released on combustion of  1 mole of methane = 802 kJ kJ/mol

According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

1 mole of [tex]CH_4[/tex] weighs = 16 g  

Thus we can say:  

16 g of [tex]CH_4[/tex] on combustion releases heat = 802 kJ

Thus 24.8 g of [tex]CH_4[/tex] on combustion releases =[tex]\frac{802}{16}\times 24.8=1243.1kJ[/tex]

Thus heat released when 24.8 g of methane is burned in excess oxygen gas is 1243.1 kJ

Explanation:

Mosquitos mainly carry Malaria since the dawn of men.

Answer:

malaria

Explanation:

"Malaria" is a mosquito-borne illness that is caused by a parasitic protist called "Plasmodium protozoa." These parasites are carried by mosquitoes. Once a mosquito bites a human, it creates an opening for the parasites to enter. The parasites then become harmful once they enter the human body. They infect the human's Red Blood Cells (RBCs), which causes several symptoms such as fever, fatigue, headache, cough, nausea, etc.

Explanation:

Answer:

Volume occupied by oxygen gas at 15 degree centigrade​ is equal to [tex]316.5[/tex] centimeter cube

Explanation:

Assuming Pressure is constant.

[tex]\frac{V_1}{T_1} = \frac{V_2}{T_2}[/tex]

where T1 and T2 are temperature in Kelvin

Substituting the give values we get-

[tex]\frac{300}{273} = \frac{V_2}{288}[/tex]

[tex]V_2 = \frac{288*300}{273} \\V_2 = 316.5[/tex]

Volume occupied by oxygen gas at 15 degree centigrade​ is equal to [tex]316.5[/tex] centimeter cube
