Boyle's law gives the relationship between pressure of a gas and volume of gas.
It states that at constant temperature, pressure of gas is inversely proportional to volume of gas.PV = k
where P - pressure V- volume and k - constant
P1V1 = P2V2
since the gas occupies the volume of the container, volume of gas is taken as volume of container.
100kPa x 5.0 L = 50 kPa x V
V = 10.0 L
Answer is C.
Answer:
3I^-/I3^-//Tl3^+//Tl^+
Explanation:
Based on the given reduction potentials, the half reaction equation having greater positive value will be the cathode while the half reaction equation having less positive reduction potential will be the anode.
This implies that this equation:
Tl3+ (aq) + 2e- → Tl+ (aq) ξo = 1.24 occurs at the cathode
While:
3 I- (aq) → I3- (aq) + 2e- ξo = -0.55 occurs at the anode
Cell notation,
Anode//cathode
Hence for this system under consideration:
3I^-/I3^-//Tl3^+//Tl^+
Al belongs to group III elements in periodic table so it forms Al3+ ion. check w the formula Al2O3: 2x(+3) from Al = +6 which equal to 3x(-2) from O. so its balanced.
Al ionizes from neutral to Al3+ and 3 e- to bond w O.
Answer:
False
Explanation:
An object with a density greater than 1.00g/mL (greater than the density of water) will sink. An object with a density less than the density of water, will float.
Answer:
all of these are properties of metalloids
