What is the concentration of nitrate ions in a 0.225 msr(no3)2 solution?
12345 [234]

Answer : The concentration of nitrate ions is 0.450 m.

Solution : Given,

Molarity of Sr(NO_3)_2 = 0.225 m

The balanced ionic equation is,

Sr(NO_3)_2\rightarrow Sr^{+2}+2NO^-_3

From the reaction, we conclude that the 1 mole of Sr(NO_3)_2 produces 2 moles of NO^-_3 ions. That means the concentration of nitrate ions is twice the value of Sr(NO_3)_2.

then, 0.225 m of Sr(NO_3)_2 gives 2 × 0.225 of NO^-_3 ions

Now the concentration of NO^-_3 ions is equal to 0.450 m.

<h2>Plasma is most likely inflence by - Option C</h2>

This plasma is most likely influenced by magnetic and electric fields. The massive positively charged ions which are influenced the lighter electrons than replace the ions to keep charge impartiality.

Therefore electric field influence the plasma. The movement of charged particles identical to a magnetic field line is not influenced. Plasma contains charged particles which are positive nuclei and negative electrons which can be molded and restricted by magnetic forces.

Alike iron filings in the closeness of a magnet, bits in the plasma will ensue magnetic field lines.

Mention three scientist that defined acid
kirill [66]

Answer:

1. Svante Arrhenius

2. Johannes Nicolaus Brønsted and Thomas Martin Lowry

3. Gilbert N. Lewis

Explanation:

The scientist mentioned above researched and made their tested hypothesis available for further research to be built on them and they do these researches to help human understanding of the field and therefore improve knowledge.

Through their different definitions of acid which includes the ability of hydrogen ion (H+) to be produced when a substance is separated from water, the ability of acid to donate a proton (H +), It can be concluded that acids contain hydrogen and they have the ability to donate that  (H +) to other substance.

What does it mean if a solid is malleable?
Nat2105 [25]

Answer:

Option C

Explanation:

The answer to this question will be the third option "It is bendable." Malleable means to be able to change the shape of a object without damaging or breaking it. In this case a malleable solid would be for example drainage pipes. These pipes have curves and different shapes but still remain its product of a metal.

Hope this helps!
