Hi, can someone help me balance this chemistry equation: H2SO4 + RbOH -> Rb2SO4 + H2O

Chemistry

H2SO4 + 2RbOH -> Rb2SO4 + 2H2O

If you want an explanation, keep reading.

In the first portion, there are two hydrogen ions and four sulfate ions.

The second portion has one rubidium ions and one hydroxide ion.

On the other side of the equation, in order to keep those two rubidiums balanced, you'll need to add a two at the beginning of the second portion, but in that process you are giving a second hydroxide value.

Back to the right side, there is there is water (H2O).

On the first portion, there were two hydrogen ions. The second portion also has two hydroxides because of the value change (adding the two to the front).

So on the fourth portion, you'd have to add another two so you could balance the four hydrogen ions (H2 and 2OH) and the two oxygen ions (2OH).

I hope this was easy to understand.

mojhsa [17]

Answer:

The answer to your question is: CO2

Explanation:

The information given is correct, Covalent bonds occur when atoms share one or more pairs of electrons, but also, covalent bonds occur with nonmetals, then,

a.NaCl     This elements form an ionic bond, so this option is incorrect.

b.Cl2      Here there are two non metals  but the form one single covalent bond, so this option is incorrect.

4,410 kJ

Explanation:

Gravitational Potential Enegry (GPE) is calculated as;

GPE = <em>m*g*h</em>                           where;

m = mass (kg)

g = gravity (m/s²)

h = height (meters)

= 90 * 9.8 * 5000

= 4,410,000‬ joules

= 4,410 kJ

In the lab there is a vile of mercury and it has a mass of 43.0 grams. If the density of mercury is 13.6 g/mL, what is the volum
Vitek1552 [10]

Answer:

<h2>The answer is 3.16 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}

From the question

mass = 43 g

density = 13.6 g/mL

The volume is

volume =  \frac{43}{13.6}  \\   = 3.161764

We have the final answer as

<h3>3.16 mL</h3>

Hope this helps you
