Answer is: <span>solid wood.
There are </span>five fundamental states of matter (gas, liquid, solid, plasma and Bose–Einstein condensate).
<span>In solid, molecules are closely packed, stiff and do not changes of shape or volume. S</span><span>olid object (in this example wood) does not take on the shape of its container.
</span>Liquids (in this example water) <span>have definite volume, but no fixed shape.
</span>Gases (in this example nitrogen and neeon) not have definite volume and fixed shape, it depends on its container.
Answer:I think that you may should ask your teacher
Explanation:
2h-7 I had that before unless I’m tripping but I did rechecked
The chemical formula of nitrogen dioxide is NO2. It is a brown coloured gas.
Answer:
We have 1.69 moles of gas inside the balloon
Explanation:
Step 1: Data given
Volume of the balloon = 18.9 L
Temperature = 27.1 °C = 300.25 K
Pressure in the balloon = 2.20 atm
Step 2: Calculate the number of moles
p*V = n*R*T
n= (p*V)/(R*T)
⇒with n = the number of moles of gas
⇒with p = the pressure of gas = 2.20 atm
⇒with V = the volume of the gas = 18.9 L
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature = 27.1 °C = 300.25 K
n = (2.20 * 18.9) / ( 0.08206*300.25)
n = 1.69moles
We have 1.69 moles of gas inside the balloon
