write at least on paragraph about space exploration and why it interests you. The moon can certainly be your focus however, you

may be interested in exploring other planets within or outside our own solar system.

Write the formula of the conjugate acid of HCO₂⁻.

Alex

Taking into account the Brønsted-Lowry acid-base theory, the conjugate acid of HCO₂⁻ is H₂CO₂.

<h3>Brønsted-Lowry acid-base </h3>

The Brønsted-Lowry acid-base theory (or the Brønsted-Lowry theory) identifies acids and bases based on whether the species accepts or donates protons or H⁺.

According to this theory, acids are proton donors while bases are proton acceptors. That is, an acid is a species that donates an H⁺ proton while a base is a chemical species that accepts an H⁺ proton from the acid.

So, reactions between acids and bases are H⁺ proton transfer reactions.

<h3>Conjugate base and conjugate acid</h3>

Then, a conjugate base is an ion or molecule resulting from the acid that loses the proton, while a conjugate acid is an ion or molecule resulting from the base that gains the proton:

acid + base ⇄ conjugate base + conjugate acid

<h3>Conjugate acid of HCO₂⁻</h3>

Like a conjugate acid is an ion or molecule resulting from the base that gains the proton, the conjugate acid of HCO₂⁻ is H₂CO₂.

A student mixed 115 g of sugar, 350 g of water and 5 g of spices. What will be the mass of the solution?

jenyasd209 [6]

Answer:

$m_{solution}=470g$

Explanation:

Hello,

In this case, a solution is formed when a solute is completely dissolved in a solvent, thus, for this situation, the sugar is the solute and the water the solvent but in addition to them we find spices which are also considered in the total mass of the solution. In such a way, for computing the total mass we must add the mass of three constituents (115 g sugar, 350 g water and 5 g spices) as shown below:

$m_{solution}=115g+350g+5g\\\\m_{solution}=470g$

Best regards.

Why does the moon spin around the earth and the earth spins around the sun

liberstina [14]

This easy bro there is only one answer Gravity

but here my advance word

Sometimes the gravity of big objects would capture smaller ones in orbit. This could be one way the planet acquired the moon
