Answer:
113.80 mL
Explanation:
Given that:
Volume [tex]V_1 = 140 mL[/tex]
Temperature [tex]T_1 = 35.0^0C[/tex]
[tex]= (273 + 35) = 308 \ K[/tex]
Pressure [tex]P_1 = 697 mmHg[/tex]
At standard temperature and pressure;
Temperature [tex]T_2 = 273 K[/tex]
Pressure[tex]P_2[/tex] = 760 mmHg
Using the formula for a combined gas law:
[tex]\dfrac{P_1V_1}{T_1} = \dfrac{P_2V_2}{T_2}[/tex]
[tex]V_2 = \dfrac{P_1V_1T_2}{T_1P_2}[/tex]
[tex]V_2 = \dfrac{697 \ mmHg \times 140 \ mL \times 273 \ K }{308 \ K \times 760 \ mmHg}[/tex]
[tex]\mathbf{V_2 = 113.80 \ mL}[/tex]
Calculate the molarity of 32.5 g of MgS in 935 mL of solution.

Question 21 of 25
Which of the following best describes an Arrhenius acid-base reaction?
O A. Acid + base = H+ + OH-
B. Acid + base = salt + water
C. Acid + base = conjugate base + conjugate acid
D. Acid + base =
H20
Answer:
B. Acid + base = salt + water
Explanation:
In accordance to the proposal of a scientist called Svante Arrhenius, an acid is a substance that increases the H+ concentration of a solution by dissociating into it while the base increases the OH- concentration of a solution by dissociating into it. Furthermore, Arrhenius stated that this two ions combine in an aqueous solution to give water.
Hence, Arrhenius acid-base reaction is the combination of an acid and base to produce salt and water as products. That is; Acid + base = salt + water.
If a combination reaction takes place between lithium and fluorine, the chemical formula for the product is A. LF B. LiF C. LiF2 D. Li2F

For a particular reaction at 135.4
°C, Δ=−775.41 kJ/mol
, and Δ=817.91 J/(mol⋅K)
.
Calculate ΔG for this reaction at 12.7
°C.
Answer:
[tex]\Delta G=-675.38 \frac{kJ}{mol}[/tex]
Explanation:
Hello!
In this case, for this problem, it is possible to use the thermodynamic definition of the Gibbs free energy:
[tex]\Delta G=\Delta H-T\Delta S[/tex]
Whereas G, H and S can be assumed as constant over T; thus, we can calculate H at 135.4 °C:
[tex]\Delta H=\Delta G+T\Delta S\\\\\Delta H=-775.41\frac{kJ}{mol}+(135.4+273.15)K*(0.81791\frac{kJ}{mol*K} )\\\\\Delta H=-441.58\frac{kJ}{mol}[/tex]
Now, we can calculate the Gibbs free energy at 12.7 °C as shown below:
[tex]\Delta G=-441.58\frac{kJ}{mol} -(12.7+273.15)K*0.81791\frac{kJ}{mol*K}\\\\\Delta G=-675.38 \frac{kJ}{mol}[/tex]

Explanation:
Round 87.073 meters to 3 significant figures. write your answer in scientific notation. step 1: 87.073 rounds to step 2: write scientific notation : meters...
One mole of aluminum contains 6.022 × 10²³ atoms. This number is called Avogadro number. Therefore, 0.55 moles of aluminum contains 3.31 × 10²³ atoms.
What is Avogadro number ?One mole of any substance contains 6.022 × 10²³ atoms. This number is called Avogadro number. One mole of every elements contains Avogadro number of atoms.
Aluminum is 13th element in periodic table. It shows metallic properties as well as some non-metallic properties. The symbol of aluminum is Al. It forms compounds mostly through covalent bonding.
One mole of aluminum contains 6.022 × 10²³ atoms.
Thus, number of atoms in 0.55 moles = 0.55 × 6.022 × 10²³ = 3.31 × 10²³ atoms.
Therefore, the number of Al atoms in 0.55 moles is 3.31 × 10²³ .

An element that is likely to combine with other elements to form new substances is said to be ______.
A. buoyant
B. chemically reactive
C. metallic
D. solid at room temperature
Answer:
B. Chemically reactive
Explanation:
A Chemically reactive element is an element that is likely to combine with another element to form new substances
The reactivity of the element depends on the number of electrons in the outermost energy level and even the distance of the outermost energy level from the nucleus. From the periodic table, Fluorine is the most reactive non-metal while francium is the most chemically reactive metal
