Answer:

The new volume of the vessel is 250 L

Explanation:

Step 1: Data given

The volume of the cylinder = 20.0 L

The initial pressure of the gas = 25 atm

The pressure drops to 2 atm

Step 2: Calculate the volume of the vessel

P1*V1 = P2*V2

⇒with P1 = the initial pressure = 25 atm

⇒with V1 = the initial volume = 20.0 L

⇒with P2 = the final pressure = 2 atm

⇒with V2 = the final volume = TO BE DETERMINED

25 atm* 20.0 L = 2.0 atm * V2

V2 = 250 L

The new volume of the vessel is 250 L

An acid-base reaction will always produce water and which one of the
Nonamiya [84]

Answer: Option D) Salt

Explanation:

An example of acid-base reaction is

HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

Acid + base → Salt + Water.

Here, water H2O and salt, NaCl are produced.

Usually, the acid, aqeous HCl reacts completely with an appropriate amount of the base, aqueous NaOH to produce salt, aqueous NaCl and water, liquid H2O only, in a process also known as neutralization reaction

An unknown insoluble substance displaced the water shown. It's mass is indicated on the triple beam balance. Mass = A. 694 B. 69
vodka [1.7K]

Answer:

D. 693.8.

Explanation:

  • The first scale of the triple beam balance indicate that the mass is 600.
  • The second scale of the triple beam balance indicate that the mass is 690.
  • The third scale of the triple beam balance indicate that the mass is higher that 693.5 and the scale is near but lower than 694, so the mass = 693.8.c

Predict the bond angles for each of the following labeled bonds.
boyakko [2]

The bond angles a and b are 120° respectively. The bond angle c is 111.4° .while the bond angle d is 120°. The bond angles e and f are 120° respectively.

In the carbonate ion, all the bond angles and bond lengths are equal hence three equivalent resonance structures can be drawn for the ion. All the bond angles, ( a and b) in carbonate ion all have bond angle of 120°.

The bond angle marked c in OCCl2 has a bond angle 111.4°, the bond angle marked d in the compound has the bond angle, 120°.

There are three bond angles present in the nitrate (NO3-) ion. Three resonance structures contribute to this bond. Based on these structures, the bond angles e and f in the molecule is 120°.
