Find the volume. mass is 9.75 g and the density is 15.6 g/cm3

Leni [432]

Answer:

1.6cm3

Explanation:

density = mass/volume

15.6g/cm3= 9.75 g/volume

15.6/9.75 = volume

1.6cm3 = volume

These are the photos for part A

Alla [95]

Answer:

Explanation:

For part C, this should be what the graph looks like.

The reactants should have higher energy that the products so that it can release energy. Recall the reaction is N2 + 3H2 => 2NH3 + energy, making it exothermic. Apparently, you are supposed to adjust the energy diagram on the simulation so that 20% of the reactants become the products.

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation: ()zn

Bingel [31]

Based on the chemical equation, to balance the equation we use 2 as a coefficients of HCl on left hand side of reaction.

<h3>What is balanced equation?</h3>

Balanced chemical equations are those equation in which each entities are present in same amount on left side as well as on the right side of the chemical reaction.

Given chemical reaction is:

Zn + HCl → ZnCl₂ + H₂

Above reaction is not balanced equation as number of chlorine and hydrogen atoms are not same, so balanced equation will be:

Zn + 2HCl → ZnCl₂ + H₂

Hence we add 2 as a coefficient of HCl to balance the equation.

A reaction rate increases by a factor of 655 in the presence of a catalyst at 37°C. The activation energy of the original pathwa

irinina [24]

For a reaction rate that increases by a factor of 655 in the presence of a catalyst at 37°C, the activation energy of the new pathway is mathematically given as

Ea2=89.28JKoule/mol

<h3>What is the activation energy of the new pathway, all other factors being equal?</h3>

Generally, the equation for the rate constant is mathematically given as

K=Ae^{Ea1/Rt}

Therefore

$\frac{1}{655}=\frac{1}{8.31*3.10}(Ea2-105000)$

Ea2=89286.083Joule/mol

In conclusion, the activation energy

Ea2=89.28JKoule/mol
