Answer:

this is an example

Explanation:

Yes, the balloon will burst at room temperature.

As we know that, 480 x 7/8 = 420 is the maximum Stretching capacity of the balloon.

b) V. / T. = V/T

Where

V = 480 ml and T. = 5 C(278 K)

And T= 30 C( 303 K)

V = V.T/T.

V = 480 x 303/278

V = 523.1 ml

b)V./V=T./T ?

Where

V = 480 ml and

T = 5 C (278 K)?

And V = 420 ml

T=T.V./V

=278 x 480/420

= 317.17 k

Therefore the balloon will burst at the temperature of 317.17 k

The temperature of 0.5 kg of water is 303 K. It is cooled to 278 K by keeping it in a refrigerator. what is the time taken by water to reach 278 K if 87.5 J of heat is given out in each second? ( specific heat capacity of water is 4200 J/kg K )

Not sure what you are asking. I have two possible answers though...

It could either be more negatively charged, or valence electrons.

The more away from the nucleus a electron is, the more negatively charged it is.

The electrons on the outermost electron shell is valence electrons.

Again, I don't know what you were asking, but one of these answers may be correct.

A 52.0 mL portion of a 1.20 M solution is diluted to a total volume of 278 mL. A 139 mL portion of that solution is diluted by a
RoseWind [281]

Answer:

C_3=0.125M

Explanation:

Hello!

In this case, we can divide the problem in two steps:

1. Dilution to 278 mL: here, the initial concentration and volume are 1.20 M and 52.0 mL respectively, and a final volume of 278 mL, it means that the moles remain the same so we can write:

V_1C_1=V_2C_2

So we solve for C2:

C_2=\frac{C_1V_1}{V_2}=\frac{52.0mL*1.20M}{278mL}\\\\C_2=0.224M

2. Now, since 111 mL of water is added, we compute the final volume, V3:

V_3=139+111=250mL

So, the final concentration of the 139 mL portion is:

C_3=\frac{139 mL*0.224M}{250mL}\\\\C_3=0.125M

Best regards!

larisa86 [58]
When water freezes into ice, some of the properties have change. What stays the same.




Answer: 1: Ice Melting is a physical change. When liquid water (H2O) freezes into a solid state (ice), it appears changed; However, this change is only physical as the the composition of the constituent molecules is the same: 11.19% hydrogen and 88.81% oxygen by mass.
