This is a combustion reaction because it is being combined with oxygen. Then to balance you will put the number of carbons you have or 4 in front of the CO2 and then same with H2. Then you will add up the oxygen and divide it by two to get. 1, (13/2), 4, 5
Answer:
the heat is circulating in the same spot rather than airing out into the open
Explanation:
The volume of the rectangle has been given by the product of length, breadth, and height. The mass of the air with a density of 1180 g/m³ is 708.57 gms.
<h3>What is density?</h3>
The density of the substance has been known to be given by the mass's ratio to the volume. The formula for density is given as,
Density = Mass ÷ Volume
Given,
Density = 1180 g/m³
The volume of the rectangle = L×B×H
Substituting the values above,
Mass = Density × Volume
M = 1180 × 1.2 × 10⁻² × 8.34 × 10¹ × 6.0 × 10⁻¹
= 708.57 gm
Therefore, the mass of the air is 708.57 gms.

Answer:
1.38 atm
Explanation:
Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant
P1V1= P2V2
P1 = 2.2 atm, V1 = 2.5L ,
P2 = ? , V2 = 4L
2.2 × 2.5 = P2 × 4
Divide both sides by 4
P2 = 5.5 ÷ 4
P2 = 1.38 atm
