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
Using P1V1/T1 = P2V2/T2, 1 being the conditions initially and 2 being the secondary conditions…. always make sure you convert you units first , L=695.8262L
Answer:
0.2 M.
Explanation:
- For the acid-base neutralization, we have the role:
The no. of millimoles of acid is equal to that of the base at the neutralization.
<em>∴ (XMV) KOH = (XMV) H₂SO₄.</em>
X is the no. of reproducible H⁺ (for acid) or OH⁻ (for base),
M is the molarity.
V is the volume.
X = 1, M = 0.5 M, V = 38.74 mL.
X = 2, M = ??? M, V = 50.0 mL.
∴ M of H₂SO₄ = (XMV) KOH/(XV) H₂SO₄ = (1)(0.5 M)(38.74 mL)/(2)(50.0 mL) = 0.1937 M ≅ 0.2 M.
Answer:
C phosphorus has 5 bond sites.
Answer:
I think it's c). <em>Radiation. </em>I wasn't really sure so I done a go o.gle search and that is what I found. If you want further information, here it is: On Earth, heat travels by conduction, convection and radiation. In space, conduction and convection are almost entirely non-existent. Radiation is the primary way that heat travels in space. Pls let me know if this helps. Mark as brainliest if u can.
