Answer:

yes it is balanced.

Explanation:

when you are balancing an equation you look at the elements or compounds on the reactants and product side, which must have the same number of elements on both sides. like the question above;

2 potassium on the reactant and product side.

2 chlorine on the reactant and product side.

6 oxygen on the reactant and product side.

If an object has an acceleration of 9.8 m/s and a force of 58.8N what is the mass of an object ? What could the object be
Makovka662 [10]

Answer:

The mass of an object  is 0.6122 Kg

Explanation:

Given:

Acceleration  = 9.8 m/s

Force  = 58.8 N

To Find:

Mass of an object = ?

Solution:

We know that according to newtons 2nd law

Force is the product of the mass and acceleration

F= ma

where

F = Force

m = mass

a =  Acceleration

Substituting the values,

58.8 = m X  9.8

m= \frac{58.8}{9.8}

m = 0.6122 kg

Suppose you have 15.0 ml of zinc. What volume of aluminum would have the same mass as the zinc?
Black_prince [1.1K]

Answer:

\large \boxed{\text{41.2 cm}^{3}}

Explanation:

1. Mass of zinc

The density of zinc is 7.14 g/cm³

D = m/V

\begin{array}{rcl}7.14 & = & \dfrac{m}{15.0}\\\\m & = & 7.14 \times 15.0\\& = & \text{107.1 g}\\\end{array}\\

2. Volume of aluminium

The density of aluminium is 2.60/cm³.

\begin{array}{rcl}2.60 & = & \dfrac{107.1}{V}\\\\2.60V & = & 107.1\\V& = &\dfrac{107.1}{2.60}\\\\& = &\textbf{41.2cm}^{\mathbf{3}}\\\end{array}\\\large \boxed{\textbf{41.2 cm}^{\mathbf{3}}}\text{ of aluminium have the same mass as 15.0 cm$^{3}$ of zinc.}
