This Is Actually Science And I Will Give Brainliest But U Have To Show Your Work

Answers

Answer 1

Answer:

I think it's 3.01 meters per second

Answer 2

To find the speed, you divide distance by time. So, you do 100 divided by 33.2, which equals 3.01 I think. I hope this helped.

What do you use to determine molar mass?

Answers

Answer:

the molar mass of any element can be determined by finding the atomic mass of the element on the periodic table for example, if the atomic mass of sulfer is 32.066 amu, then it's molar mass is 32.066 g / mol

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

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].
