Answer:
H₂SO₄ will be the limiting reagent.
Explanation:
The balanced reaction is:
2 Al(OH)₃ + 3 H₂SO₄ → Al₂(SO₄)₃ + 6 H₂O
The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
To determine the limiting reagent, it is possible to use the reaction stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction).
You can use a simple rule of three as follows: if by stoichiometry 2 moles of Al(OH)₃ reacts with 3 moles of H₂SO₄, how much moles of H₂SO₄ will be needed if 0.4 moles of Al(OH)₃ react?
moles of H₂SO₄= 0.6 moles
But 0.6 moles of H₂SO₄ are not available, 0.40 moles are available. Since you have less moles than you need to react with 0.4 moles of Al(OH)₃, H₂SO₄ will be the limiting reagent.
Answer:NASA's Lunar Atmosphere and Dust Environment probe, for instance, orbits the moon and collects information about its atmosphere and surface. This important data can help scientists learn more about moons, asteroids and other objects in the solar system.
Explanation:
The metal which will reach the highest temperature is the metal with the lowest specific heat capacity.
<h3>What is the amount of heat added to each metal?</h3>
The amount of heat Q = mcΔT where
- m = mass of metal
- c = specific heat capacity of mateal and
- ΔT = temperature change
<h3>Temperature change of the metal</h3>
Making ΔT subject of the formula, we have
ΔT = Q/mc
Given that Q and m are the same for each metal,
ΔT ∝ 1/c
We see that the temperature change is inversely proportional to the specific heat capacity.
Since the metals are at the same temperature, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.
So, the metal which will reach the highest temperature is the metal with the lowest specific heat capacity.

Answer:
B
Explanation:
1 mole is equal to 58.31968 grams.
so 3.5 moles equal to answer choice B
1. Answer;
=56 g/mol
Explanation and solution;
PV = nRT
nRT= mass/molar mass (RT)
molar mass = (mass/V ) × (RT/P)
= Density × (RT/P)
Molar mass = 2.0 g/L × (0.0821 × 323 K)/0.948 atm
Molar mass = 56 g/mol
2. Answer;
Molecular mass is C4H8
Explanation;
Empirical mass × n = molar mass
Empirical mass for CH2 = 14 g/mol
Therefore;
56 g/mol = 14 g/mol × n
n = 4
The molecular formula= 4(CH2)
= C4H8
