I don't know if this is right but I hope this helps. This pulsar was later interpreted as an isolated, rotating neutron star. The energy source of the pulsar is the rotational energy of the neutron star. The majority of known neutron stars (about 2000, as of 2010) have been discovered as pulsars, emitting regular radio pulses.

The volume of a gas is 200.0 mL at 275 K and 92.1 kPa. Find its volume at STP.

ycow [4]

To solve this question we will use ideal gas equation:
$p*V=n*R*T$
Where:
p = pressure
V = volume
n = number of moles
R = gas constant
T = temperature

We can rearrange formula to get:
$\frac{p*V}{T} =n*R$
We are working woth same gas so we can write following formula. Index 1 stands for conditions before change and index 2 stands for conditions after change.
$\frac{ p_{1}*V_{1} }{T_{1}} = \frac{ p_{2}*V_{2} }{T_{2}}$

We are given:
p1=92.1kPa = 92100Pa
V1=200mL = 0.2L
T1=275K
p2= 101325Pa
T2=273K
V2=?

We start by rearranging formula for V2. After that we can insert numbers:
${ p_{1}*V_{1} *T_{2}} = { p_{2}*V_{2}*T_{1} } \\ \\ V_{2}= \frac{p_{1}*V_{1} *T_{2}}{ p_{2}*T_{1}} \\ \\ V_{2}= \frac{92100*0.2*273}{101325*275} \\ \\ V_{2}= 0.18L=180mL$

lab safety test Safety goggles and an apron must be worn when handling chemicals labeled corrosive because they:________.

Sunny_sXe [5.5K]

Answer:

The terms of biosafety in a laboratory require that the person must not have the eyes and skin exposed.

Explanation:

A corrosive substance is a substance that can damage a surface when they come into contact.

These substances represent a danger in people since they can burn the eyes, the skin, and the inside of the body since the inhalation of gases can burn the respiratory tract.

These chemical burns can be avoided by properly following the biosafety protocol that a laboratory requires the use of masks, goggles, gloves, and an apron or lab coat.
