Answer: [tex]S[/tex] is the limiting reagent
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of} S=\frac{10.0g}{32g/mol}=0.3125moles[/tex]
[tex]\text{Moles of} Ag=0.700moles[/tex]
[tex]2Ag+S\rightarrow Ag_2S[/tex]
According to stoichiometry :
1 mole of [tex]S[/tex] require = 2 moles of [tex]Ag[/tex]
Thus 0.3125 moles of [tex]S[/tex] will require=[tex]\frac{2}{1}\times 0.3125=0.6250moles[/tex] of [tex]Ag[/tex]
Thus [tex]S[/tex] is the limiting reagent as it limits the formation of product and [tex]Ag[/tex] is the excess reagent.

Explain what you discovered from the Simulation about why food coloring spreads faster in warmer water.
Answer:
The food colouring mixes through the hot water faster than it mixes with the cold water, this is because in hot water the water molecule have more energy and are moving faster than the molecules of cold water .This makes it easier for the food colouring to get mixed quickly through the hot water.

In order to form water, two hydrogen atoms and one oxygen atom must be
A. dissolved.
B. bonded.
C. divided.
D. mixed.
Answer:
B bonded
Explanation:
Two molecules of hydrogen gas (two hydrogens bonded together) are combined with one molecule of oxygen gas (two oxygen atoms bonded together) in order to form two molecules of water (two hydrogen atoms bonded to one oxygen atom). What are covalent bonds? Covalent bonds occur when two or more atoms share electrons.
In order to form water, two hydrogen atoms and one oxygen atom must be bonded. The correct option is B.
What are covalent bonds?Covalent bonds between two or more atoms occur when they share electrons. with each other.
Two molecules of hydrogen gas are combined with one molecule of oxygen gas which forms two molecules of water. Hydrogen take one electron and oxygen can donate two electrons. One oxygen shares two electron with two hydrogen with one electron gaining capacity.
Thus, in order to form water, two hydrogen atoms and one oxygen atom must be bonded. The correct option is B.

If 0.25 moles of KBr is dissolved in 0.5 liters of
heavy water which has a mass of 1,100 grams
per liter, what is the concentration?
Answer in units of m (molal).
Answer:
[KBr] = 454.5 m
Explanation:
m is a sort of concentration that indicates the moles of solute which are contianed in 1kg of solvent.
In this case, the moles of solute are 0.25 moles.
Let's determine the mass of solvent in kg.
Density of heavy water, solvent, is 1.1 g/L and our volume is 0.5L.
1.1 g = mass of solvent / 0.5L, according to density.
mass of solvent = 0.5L . 1.1g/L = 0.55 g
We convert the mass to kg → 0.55 g . 1kg /1000g = 5.5×10⁻⁴ kg
m = mol/kg → 0.25 mol /5.5×10⁻⁴ kg = 454.5 m

What is the molecular formula for a compound that is 34.31% sodium, 17.93% carbon, 47.76% oxygen and has a molar mass of 134.00g?
Answer: Na2C2O4 probably sodium oxalate
Explanation: assume you have 100 g substance.
Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.
Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.
For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you
Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.
Divide 134:67 = 2. You get formula Na2C2O4
