A 60 and N net force is applied to a 12 kg box which is the acceleration of the box?
GarryVolchara [31]

The relation between force and mass and acceleration is

Force = mass X acceleration

The SI unit will be

Force = Newton

mass =kg

acceleration=\frac{m}{s^{2} }

thus

acceleration = \frac{Force}{mass}

putting values

acceleration=\frac{60 N}{12kg}=5\frac{m}{s^{2} }

Thus the acceleration will be

5\frac{m}{s^{2} }

Copper metal (Cu) reacts with silver nitrate (AgNO3) in aqueous solution to form Ag and Cu(NO3)2. The balanced chemical equation
Rufina [12.5K]

The mass formed in a chemical reaction is given by stoichiometry law in balanced chemical equation. The mass of silver produced in the reaction is 107. 9 g.

<h3>What is the stoichiometric law?</h3>

The stoichiometric law states that in a balanced chemical equation, the stoichiometric coefficient describes the moles of each compound in a chemical reaction.

The balanced chemical equation for the reaction is:

\rm Cu\;+\;2\;AgNO_3\;\rightarrow\;Cu(NO_3)_2\;+\;2\;Ag

From the balanced chemical equation, 1 moles of copper results in 2 moles of silver.

Moles in terms of mass can be given as:

\rm Moles=\dfrac{Mass}{Molar\;mass}

Thus, moles of 31. 75 grams copper is:

\rm Cu=\dfrac{ 31. 75 }{63.5}\;mol\\ Cu=0.5 mol

The moles of Ag produced can be given from stoichiometric law as:

\rm 1\;mol\;Cu=2\;mol\;Ag\\0.5 \;mol\;Cu=0.5\;\times\;2\;mol\;Ag\\0.5\;mol\;Cu=1\;mol\;Ag

The moles of Ag produced is 1 mol.

The mass of a mole of element is equivalent to the molar mass. Thus, the mass of Ag produced in the reaction is 107. 9 g. Hence, option B is correct.

What is a change in matter that produces one or more substances?
Arte-miy333 [17]

Answer:

chemical change, or chemical reaction.

Explanation:

A change in matter that produces one or more new substances is a chemical change, or chemical reaction. In a chemical change, atoms rearrange to form new substances, which results in different physical properties, as well. ( you could have looked it up on google lol )

If the molecules in the above illustration react to form NH3 according to the equation N2 3 H2 2 NH3 , the limiting reagent is ,
Kamila [148]

Answer:

Follows are the solution to these question:

Explanation:

Given equation:

N_2+3H_2 \longrightarrow 2NH_3

In this equation:

1 N_2 gives = 2NH_3

so,

3N_2 gives=  2 \times 3 = 6 NH_3

similarly:

3H_2 gives = 2NH_3

So, 6H_2 gives = \frac{2}{3}\times 6=4NH_3

Its limited reagent is =N_2

The amount of NH_3 molecules were formed = 4.

and the amount of  H_2 excess molecules are= 1
