Hello, Brainly User!

A heterogeneous equilibrium reaction is when there are different phases in the reaction. An equilibrium reaction is a reaction that can go in both the forward and reverse directions, and the concentrations of the reactants and products remain the same.

So therefore, your answer is A. Heterogeneous!

Hope i helped and i was honored to answer your question!

Have a great day..

Answer:

0.895 g/mL

Explanation:

Step 1: Given data

Mass of liquid Z (m): 2.763 lb

Volume of liquid Z (V): 5.93 cups

Step 2: Convert "m" to grams

We will use the relationship 1 lb = 453.59 g.

$2.763 lb \times \frac{453.59 g}{1lb} = 1,253g$

Step 3: Convert "V" to milliliters

We will use the relationship 1 cup = 236.59 mL.

$5.93cup \times \frac{236.59mL}{1cup} = 1.40 \times 10^{3} mL$

Step 4: Calculate the density of the liquid Z

The density (ρ) of the liquid Z is equal to its mass divided by its volume.

$\rho = \frac{m}{V} = \frac{1,253g}{1.40 \times 10^{3}mL } = 0.895 g/mL$

Which of the following statements accurately describes how a catalyst acts in a chemical reaction?

WINSTONCH [101]

Answer:

d) II and IV only.

Explanation:

A catalyst increases the kinetic energy of reactant molecules which increases the magnitude of collision. These then decreases the activation energy . A catalyst is not consumed by reaction because it is neither reactant nor a product, hence has no effect on equilibrium constant.

As a covalent bond is a bond between atoms sharing electrons, a polar covalent bond is a covalent bond where the difference in electronegativity of the two atoms is uneven (one is greater than the other). This meaning that one atom will have a greater pull on the electrons towards them than the other and the share of electrons is uneven (definition of polar). A non polar covalent bond is one where the difference in E.N is small or non existent and the balance of shared electrons is even

How many grams of Na2O are produced when 70.7 g of Na reacts?<br> 4Na(s)+O2(g)→2Na2O(s)

LUCKY_DIMON [66]

Answer:

95.3 grams.

Explanation:

Relative atomic mass data from a modern periodic table:

Na: 22.990;
O: 15.999.

How many moles of Na are consumed?

$M(\mathrm{Na}) = \rm 22.990\; g\cdot mol^{-1}$ .

$\displaystyle n(\mathrm{Na}) = \frac{m(\mathrm{Na})}{M(\mathrm{Na})} = \rm \frac{70.7\; g}{22.990\;g\cdot mol^{-1}}=3.07525\;mol$ .

How many moles of $\mathrm{Na_2 O}$ formula units will be produced?

Consider the ratio between the coefficient of $\mathrm{Na_2 O}$ and that of $\mathrm{Na}$ in the equation:

$\displaystyle \frac{n(\mathrm{Na_2 O})}{n(\mathrm{Na})} = \frac{2}{4} = \frac{1}{2}$ .

As a result,

$\displaystyle n(\mathrm{Na_2 O}) = n(\mathrm{Na}) \cdot \frac{n(\mathrm{Na_2 O})}{n(\mathrm{Na})} = \rm \frac{1}{2}\times 3.07525\;mol = 1.53763\; mol$ .

What will be the mass of that many $\mathrm{Na_2 O}$ ?

Formula mass of $\mathrm{Na_2 O}$ :

$M(\mathrm{Na_2 O}) = \rm 2\times 22.990 + 15.999 = 61.979\; g\cdot mol^{-1}$ .

$m(\mathrm{Na_2 O}) = n(\mathrm{Na_2 O})\cdot M(\mathrm{Na_2 O}) = \rm 1.53763\; mol\times 61.979\; g\cdot mol^{-1} \approx 95.3\; g$ .
