Describe what occurs at mid-ocean ridges?

1 answer:

6 0

A mid-ocean ridge is a mountain rage under the water. It is formed due to plate tectonics. The shifting of the plates lifts up the floor of the ocean. When convection currents happen they raise the mantle that is located beneath the oceans crust and it creates magma where the two tectonic plates meet.

10) Nitrogen and hydrogen react together to form ammonia.

alexandr402 [8]

Answer:

<h2>C 28 tonnes</h2>

Explanation

7 tonnes-8.5 ammonia

1 ton will be 8.5/7=1.21

we now know what 1 ton of nitrogen is equal to

so now,34/28 that is equal to 1.21

1.21=1.21

So the answer would be C. 28 tonnes

Thanks!

In the following net ionic equation, identify each reactant as either a Bronsted-Lowry acid or a Bronsted-Lowry base. HCN(aq) H2

vfiekz [6]

Answer:

Explanation:

The definition of acids and bases by Arrhenius Theory was modified and extended by Bronsted-Lowry.

Bronsted-Lowry defined acid as a molecule or ion which donates a proton while a base is a molecule or ions that accepts the proton. This definition can be extended to include acid -base titrations in non-aqueous solutions.

In this theory, the reaction of an acid with a base constitutes a transfer of a proton from the acid to the base.

From the given information:

$\mathsf{HCN _{(aq)} + H_2O_{(l)} \to CN^{-}_{(aq)} + H_3O_{(aq)}}$

From above:

We will see that HCN releases an H⁺ ion, thus it is a Bronsted-Lowry acid

$H_2O$ accepts the H⁺ ion ,thus it is a Bronsted-Lowry base.

The formula of the reactant that acts as a proton donor is HCN

The formula of the reactant that acts as a proton acceptor is H2O
