A gold wire has a diameter of 1.00 mm. What length of this wire contains exactly 1.00 mol of gold? (density of Au = 17.0 g/cm 3)
Answers
Answer:
1476.43 cm
Explanation:
From the question given above, the following data were obtained:
Diameter = 1 mm
Number of mole of Au = 1 mole
Density of Au = 17.0 g/cm³
Length of wire =?
Next, we shall determine the mass of 1 mole of Au. This can be obtained as follow:
Number of mole of Au = 1 mole
Molar mass of Au = 197 g/mol
Mass of Au =?
Mole = mass / Molar mass
1 = mass of Au / 197
Mass of Au = 1 × 197
Mass of Au = 197 g
Next, we shall determine the volume of the Au. This can be obtained as follow:
Density of Au = 17.0 g/cm³
Mass of Au = 197 g
Volume of Au =
Density = mass /volume
17 = 197 / Volume of Au
Cross multiply
17 × volume of Au = 197
Divide both side by 17
Volume of Au = 197 / 17
Volume of Au = 11.59 cm³
Next, we shall determine the radius of the gold wire. This can be obtained as follow:
Diameter = 1 mm
Radius =?
Radius = Diameter /2
Radius = 1/2
Radius = 0.5 mm
Converting 0.5 mm to cm, we have:
10 mm = 1 cm
Therefore,
0.5 mm = 0.5 mm × 1 cm / 10 mm
0.5 mm = 0.05 cm
Thus, the radius of the gold wire is 0.05 cm
Finally, we shall determine the length of the wire. This can be obtained as follow:
Volume of Au (V) = 11.59 cm³
Radius (r) = 0.05 cm
Pi (π) = 3.14
Length (L) =?
V = πr²L
11.59 = 3.14 × 0.05² × L
11.59 = 3.14 × 0.0025 × L
11.59 = 0.00785 × L
Divide both side by 0.00785
L = 11.59 / 0.00785
L = 1476.43 cm
Thus, the length of the gold wire is 1476.43 cm

Is copper II chloride mixed with water an element, compound, or mixture? If it's a mixture is it homogeneous or heterogeneous?
Answers
Answer:
1. mixture
2. Homogenous
Explanation:
Copper II chloride is a compound because it consists of elements that are chemically combined together. When a solute in this case, copper II chloride is mixed with water- a solvent, the result is a homogenous mixture.
Homogenous substances are formed when a solute and a solvent combine, resulting in a mixture with uniform properties. Mixtures can be separated using relevant separation techniques.

How much heat is released when 1.4 mol of hydrogen fluoride are produced? H2(g) +F2(g) → 2HF(g) +536kJ (Please show work)
Answers
Answer:
375.2 kJ
Explanation:
H₂(g) +F₂(g) → 2HF(g) +536kJThe information the equation above provides lets us know that when 2 mol of hydrogen fluoride (HF) are produced, 536 kJ of energy (as heat) is produced.
We can then state a rule of three:
2 mol HF -------- 536 kJ1.4 mol HF --------- XAnd solve for X:
X = 1.4 mol * 536 kJ / 2 molX = 375.2 kJList two factors that affect climate

Which of these is evidence that an unbalanced force is acting on an object?
The motion of the object is changing
The mass of the object is changing.
The object continues moving in a straight line
The object remains at rest.
Answers
Answer:
The motion of the object is changing
Explanation:
Objects will only change their motion (direction, speed) if there is an unbalanced force of some kind acting on them. Balanced forces result in no change in the object's state of motion.
The motion of the object is changing.
Objects will only change their motion (direction, speed) if there is an unbalanced force of some kind acting on them. Balanced forces result in no change in the object's state of motion.
What is motion ?
"Change with time of the position or orientation of a body. Motion along a line or a curve is called translation. Motion that changes the orientation of a body is called rotation."
What is force ?"A force is a push or pull upon an object resulting from the object's interaction with another object."

La densidad del aire contenida en una habitación es 0.0013 g/cm3. si las dimensiones de la habitación son 4m de ancho, 5m de largo y 2.5m de alto, ¿ que nada tiene el aire contenido?
Answers
Answer:
La masa del aire contenido en la habitacion es 65000 gramos.
Explanation:
La densidad se define como la propiedad que tiene la materia, ya sean sólidos, líquidos o gases, para comprimirse en un espacio determinado. En otras palabras, la densidad es una magnitud que permite medir la cantidad de masa que hay en determinado volumen de una sustancia. Entonces, la expresión para el cálculo de la densidad es el cociente entre la masa de un cuerpo y el volumen que ocupa:
[tex]d=\frac{m}{V}[/tex]
En este caso:
d= 0,0013 [tex]\frac{g}{cm^{3} }[/tex]m=?V= 4 m*5 m*2,5 m= 50 m³= 50.000.000 cm³ (siendo 1 m³=1.000.000 cm³)Reemplazando:
[tex]0,0013\frac{g}{cm^{3} }=\frac{m}{50000000 cm^{3} }[/tex]
Resolviendo obtienes:
m= 0,0013 [tex]\frac{g}{cm^{3} }[/tex] * 50.000.000 cm³
m=65000 g
La masa del aire contenido en la habitacion es 65000 gramos.

3 Mg + 2 FeCl3 +2 Fe + 3 MgCl2
Your answer should include the half equations
Answers
Answer:
because Redox means two words:reduction and oxidation
reduction is when oxygen is taken from a substance while oxidation is the addition of oxygen to a substance..Magnesium displaces chlorine from iron(fe)because it is more reactive than iron
and iron gives chlorine to magnesium because it's less reactive.This is due to their position on reactivity series.
Explanation:
This is called displacement reaction where by A most reactive metal remove a substance from a less reactive metal and form up a salt
and in this case the salt formed in the reaction is 3MgCl
