6 0

Answer:

The size of a phosphorus atom also interferes with its ability to form double bonds to other elements, such as oxygen, nitrogen, and sulfur. As a result, phosphorus tends to form compounds that contain two P-O single bonds where nitrogen would form an N=O. double bond.

.A volumetric pipette is used to measure 25.0cm3 of 2.0mol/dm3 aqueous sodium hydroxide into aconical flask.A burette is filled

Mila [183]

Answer:

A volumetric pipette is used to measure 25.0cm3 of 2.0mol/dm3 aqueous sodium hydroxide into aconical flask.

A burette is filled with dilute sulfuric acid.

Write a balanced symbol equation for the reaction between these chemicals when we neutralise.

Explanation:

The reactants of the given reaction are:

sodium hydroxide and dilute sulfuric acid.

The balanced chemical equation of the reaction is:

$H_{2}SO_{4} (aq) + 2NaOH(aq) -> Na_{2} SO_{4} (aq)+ 2H_{2} O(l)$

Acid and base raect with each other and form salt and water.

This reaction is called a neutralization reaction.

If the point of the nail can be approximated as a circle with

maw [93]

Answer:

P = 795.77 Mpa

Explanation:

Given that,

Force exerted by the hammer, F = 10⁴ N

The nail can be considered as a circle with radius of $2\times 10^{-3}\ m$

We need to find the pressure exerted on the wall. Pressure is equal to force acting per unit area. So

$P=\dfrac{F}{A}\\\\P=\dfrac{10^4\ N}{\pi \times (2\times 10^{-3})^2}\\\\P=795774715.45\ Pa$

We know that, 1 MPa = 1000000 Pa

So, P = 795.77 Mpa

So, the pressure exerted on the wall is 795.77 Mpa.

- How many moles of S2 are needed to produce 1.50 moles of SO2 gas? S2 + 20, ----> 2802

matrenka [14]

Answer:

0.75 moles

Explanation:

S2 + 2O2 = 2SO2

From the reaction above,

We see that number of moles attached to S2 is 1 and number of moles attached to SO2 is 2.

Since we want to find how many moles of S2 are needed to produce 1.50 moles of SO2 gas

The answer is gotten by proportion;

Number of moles = 1/2 × 1.5 = 0.75 moles

An interpretation of the results of many tests is called A) an experiment. B) a prediction D) a theory

nydimaria [60]

Answer:

B) a prediction

Explanation:

It is not option A because an experiment is one or more tests to see the check of a phenomenon in certain circumstances.

The idea is to validate or refute a hypothesis.

It is not option C because one theory is based on many proven hypotheses.

The correct option is B, a prediction. It is the principle that will lead us to a theory.
