Plz answer correctly.. I need it ASAP

Answers

Answer 1

If all the particles in a material are made up of

several smaller particles, and every larger particle

is identical, is the material a pure substance or

not? Explain your reasoning.

A pure substance is something like a compound and element. This material made of several particles which seem to be two different particles, I believe, is a mixture. So, it is not a pure substance mixtures are made up of more than one particle while compounds (In a fixed ratio, the fusion of two or more than two atoms) and elements are made up of one molecule essentially.

Answer 2

The given material is not a pure substance as it is made up of several smaller particles and some larger particles that are identical.

What is pure substance?

A pure substance is defined as a substance that has fixed chemical composition throughout the substance. A pure substance are not necessarily have to be of single substance or compound.

The given material is not a pure substance because it is made up of several different small particles. The material is made up of both small particle and large particles and both the particle do not have similar composition.

A pure substance is a homogeneous mixture. These substance has similar composition throughout the substance size of the particle  does not matter.

Thus, it is not a pure substance as it is made up of several smaller particles and some larger particles that are identical.

heated to 100 degrees (Celcius) what is the new pressure in mmHg?

Answers

The new pressure : P₂ = 1038.39 mmHg

Further explanation

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

The symbol equation for combustion of a hydrocarbon is shown below. What number will go before the oxygen reactant when
this equation is balanced?

Answers

Answer:

Yes it is indeed

Explanation:

Thanks if you found this helpful

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

What is chemical equation?

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].

How much heat is released when 24.8 g of ch4 is burned in excess oxygen gas?

Answers

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
