pishuonlain [190]

Answer:

Succinic acid

Explanation:

The most common possibility is succinic acid

As it has decimals after whole no till hundredth it contains OH and C in most of the cases .

Let's check for succinic acid

  • C4H_6O_6
  • 4(12)+4(16)+6
  • 64+48+6
  • 118u

Yes approximately equal

Molecular formula is.

Fudgin [204]
The correct answer of the given question above would be option B. IRON 0.449. Based on the given details above about an unknown substance that has a mass of 14.7 g and  the substance absorbs 1.323×102 J of heat, the temperature of the substance is raised from 25.0 ∘C to45.0 ∘C, most likely, the substance is IRON. Hope this answers the question.

neonofarm [45]

Answer:

The answer is B

Explanation:

Less air means less air pressure. At a certain point, there is very little air pressure to push against the outward pressure of the helium inside the balloon. It will then expand until the rubber breaks, and the balloon bursts

A 1.04L sample of gas of 759 mm Hg pressure is expanded
Marta_Voda [28]

Answer:

P2 = 352 mm Hg (rounded to three significant figures)

Explanation:

PV = nRT

where P is the pressure,

V is the volume,

n is the moles of gas,

R is the gas constant,

and T is the temperature.

We must relate this equation to a sample of gas at two different volumes however. Looking at the equation, we can relate the change in volume by:

P1V1 = P2V2

where P1 is the initial pressure,

V1 is the initial volume,

P2 is the final pressure,

and V2 is the final volume.

Looking at this relationship, pressure and volume have an indirect relationship; when one goes up, the other goes down. In that case, we can use this equation to solve for the new pressure.

P1V1 = P2V2

(759 mm Hg)(1.04 L) = P2(2.24 L)

P2 = 352 mm Hg (rounded to three significant figures)

A solid is 5 cm tall, 3 am wide, and 2 cm thick. It has a mass of 135 g. What is the solid's density?
gizmo_the_mogwai [7]

<u>Answer:</u>

density of solid = 4.5 g/cm³

<u>Explanation:</u>

density = mass ÷ volume

• We know the mass of the object (135 g). We need to calculate the volume:

Volume = length × width × thickness

             = 5 cm × 3 cm × 2 cm

             = 30 cm³

• Now we can calculate the solid's density:

density = 135 g ÷ 30 cm³

            = 4.5 g/cm³
