What is the density of a piece of wood that has a mass of 35.0 grams and a volume of 26.4 cm3
vladimir2022 [97]

Answer:

We have the final answer as

<h2>1.33 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

<h3>density =  \frac{mass}{volume}</h3>

From the question

mass = 35 g

volume = 26.4 cm³

The density of the wood is

density =  \frac{35}{26.4}  \\ 1.325757575757...

We have the final answer as

<h3>1.33 g/cm³</h3>

Hope this helps you

What is the Brønsted-Lowry base in this reaction: NH2−+CH3OH→NH3+CH3O−?(1 point)
Viefleur [7K]

The Brønsted-Lowry base in the given reaction is NH₂⁻. The correct option is the fourth option NH2−

To determine which is the Brønsted-Lowry base in the given reaction:

NH2−+CH3OH→NH3+CH3O−

First, we will write the equation for the reaction properly

The equation is:

NH₂⁻ + CH₃OH  → NH₃ + CH₃O⁻

Now, to determine which among the species in the above reaction is the Brønsted-Lowry base, we will start by defining what a <em>Brønsted-Lowry base</em><em> </em>is.

A Brønsted-Lowry base is any species that is capable of accepting a proton, which requires a lone pair of electrons to bond to the H⁺.

In simple terms, a Brønsted-Lowry base is a proton acceptor.

In the above reaction, NH₂⁻ is the species that is capable of accepting a proton and it has a lone pair of electrons to bond to the H⁺.

∴ NH₂⁻ is the Brønsted-Lowry base in the reaction

Hence, the Brønsted-Lowry base in the given reaction is NH₂⁻. The correct option is the fourth option NH2−
