It should be mass and speed so they are both incorrect because the height doesn’t mean much, but what matters is how heavy the object is, and how fast it’s going to go.
Answer: 0.27L
Explanation:
Given that,
Original volume V1 = 400.0 mL
convert volume in milliliters to liters
(If 1000mL = 1L
400.0 mL = 400.0/1000 = 0.4 L)
Original temperature T1 = 22.0 °C
Convert temperature in Celsius to Kelvin
(22.0 °C + 273 = 295K)
Original pressure = 1000mmHg
Convert pressure of 1000mmHg to atm
(If 760mmHg = 1 atm
1000mmHg = 1000/760 = 1.316 atm)
New volume V2 = ?
New Temperature T2 = 30.0°C
(30.0°C + 273 = 303K)
New pressure P2 = 2 atm
Since pressure, volume and temperature are involved, apply the general gas equation
(P1V1)T1 = (P2V2)/T2
(1.316 atm x 0.4 L) /295K = (2 atm x V2) /303K
0.526 atmL / 295K = 2V2 / 303K
Cross multiply
0.526 atmL x 303K = 2V2 x 295K
159.47 = 590V2
Divide both sides by 590
159.47/590 = 590V2/590
0.27 L = V2
Thus, the final volume of the gas is 0.27L
Answer:
The other signal that would indicate the presence of a C= C bond appears close to 3100 
.
Explanation:
Bands that appear above 3000 are often unsaturation diagnoses suggest. The band at 3000-
3100 is characteristics for C-H stretching frequencies and normally is overlaps with the ones for alkanes because it is a band of weak intensity.
Answer:
0.0451 mol FeCl₂
General Formulas and Concepts:
<u>Chemistry - Atomic Structure</u>
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
<u>Step 1: Define</u>
5.72 g FeCl₂
<u>Step 2: Identify Conversions</u>
Molar Mass of Fe - 55.85 g/mol
Molar Mass of Cl - 35.45 g/mol
Molar Mass of FeCl₂ - 55.85 + 2(35.45) = 126.75 g/mol
<u>Step 3: Convert</u>
<u />
= 0.045128 mol FeCl₂
<u>Step 4: Check</u>
<em>We are given 3 sig figs. Follow sig fig rules and round.</em>
0.045128 mol FeCl₂ ≈ 0.0451 mol FeCl₂
Answer:
They will die off too
Explanation:
The animals that feed off the rabbits will start to die off from starvation, and so will the animals tho eat off of those. The entire food chain above the rabbits will start to decrease, while the plants and animals that the rabbits eat will increase in population due to less predators.
