Answer:
The salt is barium chloride.
Explanation:

Moles of barium sulfate =
According to reaction, 1 mol of barium sulfate is produced from 1 mol of
.
Then 0.0480 moles will be produced from:
of
.
Mass of
used = 10.00 g
Moles of
=\frac{10.00 g}{\text{Molar mass}}[/tex]

Molar mass of
= 208.33 g/mol
The nearest answer to our answer is
.
The correct answer barium chloride with molar mass of 208.2 g/mol.

Answer:
975.56×10²³ molecules
Explanation:
Given data:
Number of molecules of C₂H₆ = 4.88×10²⁵
Number of molecules of CO₂ produced = ?
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Number of moles of C₂H₆:
1 mole = 6.022×10²³ molecules
4.88×10²⁵ molecules×1mol/6.022×10²³ molecules
0.81×10² mol
81 mol
Now we will compare the moles of C₂H₆ with CO₂.
C₂H₆ : CO₂
2 : 4
81 : 4/2×81 = 162 mol
Number of molecules of CO₂:
1 mole = 6.022×10²³ molecules
162 mol ×6.022×10²³ molecules / 1 mol
975.56×10²³ molecules
External fertilization in animals usually occurs in water or in damp areas in a process called spawning.
Answer:
Mn (s) + NiCl2 (aq) → MnCl2 (aq) + Ni
Explanation:
The order of displacement of metals from aqueous solution by another metal is defined by the activity series of metals.
The activity series arranges metals in order of reactivity and increasing electrode potentials. The less negative the electrode potential of a metal is, the less reactive it is and the lower it is found in the activity series.
Nickel has a less negative electrode potential than manganese hence it is displaced from an aqueous solution of its salt by manganese spontaneously.
