What is the mass of zinc required to combine with 0.5 mol of chlorine to produce zinc chloride,ZnCI[subscript 2]?
[Relative atomic mass : Zn = 65]
Answer:
16.25g
Explanation:
Equation for the reaction = Zn + 2Cl = ZnCl2
1 molecule of Zn = 2 molecule of Cl
x mole of Zn = 0.5mol of Cl
mole of Zn = 0.25mol
mass of Zn = 0.25 * 65 = 16.25g
The mass of zinc required to combine with 0.5 mol of chlorine to produce zinc chloride is 16.25g.
What is mass?Mass is the quantity of matter in a physical body.
The reaction is Zn + 2Cl = ZnCl₂
The ratio of moles of Zn and Cl
1 : 2
m, mol of Zn is equal to 0.5 mol of Cl
Moles of Zn = 0.25 mol
Multiply the mole of Zn and the relative atomic mass of Zn
Mass of Zn = 0.25 × 65 = 16.25 g.
Thus, the mass of zinc is 16.25 g.

Laura jala un trineo una distancia de 2000 cm usando una cuerda, con una tensión constante de 80 N. La tarea requiere de 800 J de trabajo, ¿qué ángulo forma la cuerda con el suelo?
Respuesta:
60°
Explicación:
Paso 1: Información dada
Distancia recorrida (d): 2000 cmFuerza aplicada (F): 80 NTrabajo realizado (W): 800 JPaso 2: Convertir "d" a metros
Usaremos el factor de conversión 1 m = 100 cm.
2000 cm × 1 m/100 cm = 20 m
Paso 3: Calcular el ángulo entre la cuerda y el suelo (θ)
W = F × d × cosθ
800 J = 80 N × 20 m × cosθ
θ = 60°

If I had 50 graham cracker squares, 15 marshmallows, and 100 little chocolate pieces, how many total s'mores could I make before I ran out of ingredients?
2 Grahams + 1 Marshmallow + 4 Chocolate Pieces --> 1 S'more
Group of answer choices:
50
15
100
25
20
Answer: 15
Explanation:
25 graham crackers
15 marshmallows
25 chocolate pieces
would make 15 s’mores
15 s'mores can be made from the given ingredients. Therefore, option B is correct.
How many total s'mores can be made?Assuming that one graham cracker square, one marshmallow, and two little chocolate pieces to make one s'more are required, calculate the maximum number of s'mores that can be made with the given ingredients as follows:
You have 50 graham cracker squares, so you can make a maximum of 50 s'mores using all of them.You have 15 marshmallows, which is enough to make 15 s'mores.You have 100 little chocolate pieces, which is enough to make 50 s'mores (since you need two chocolate pieces for each s'more).Therefore, the ingredient you run out of first will limit the number of s'mores that can be made. Since there are only 15 marshmallows, only a maximum of 15 s'mores can be made. Therefore, option B is correct.
