Which element would you expect to have the highest electronegativity?

Answer:

The circulatory system

Explanation:

Answer:

H, Ca, Cl is the answer dude

Answer:

hydrogen is H

calcium is Ca and chlorine is Cl

Answer:

We know that 18 g of H2O contains 1 mole (or 6.022 x 10^23) molecules of water because the molar mass of H2O is 18 g/mol.

So 1 g water will contain 1/18 moles of H2O molecules.

Now 15 g of water will contain 15/18 moles of H2O.

So molecules of H2O = (15/18) x 6.022 x 10^23 = 5 x 10^23 molecules.

Answer:

The answer is relevant.

Scientific investigations must be well relevant to be sure the data collected will help answer the scientist's question.

A scientific investigation is an investigation that is done in the field of science. This unravels the secrets of the earth and the logical reason behind the things happening.

There are three types of scientific investigations. They are descriptive investigation, comparative investigation, and experimental investigation. When we see a thing happening in the environment or anywhere, always find a reason behind it.

The steps in completing a scientific investigation are:

Explanation:

let me know if u need an explanation n ill try to give one :)

False. To prepare 20.0 mL of 2.00 M solution of hydrochloric acid from 10.0 M stock solution, 4.0 mL of the stock solution and 16.0 mL of water would be needed.  

Recall the law of diffusion that:

C1V1 = C2V2, where C1 = initial concentration, V1 = initial volume, C2 = final concentration, and V2 = final volume.

In this case, if C1 =10.0 M, V1 = ?, C2 = 2.00 M and V2 = 20.0 mL

V1 = 2 x 20/10

         = 4.0 mL

Hence, 4.0 mL of the stock solution would be taken. Since the final volume is 20.0 mL, only 16.0 mL of water would need to be added and not 20.0 mL.

Answer:

480 mL

Explanation:

15L  of  0.38M of NH3(aq.) means that we require 15x0.38 moles of NH3.

this is to be provided by 15M x V.  

Where V is volume in Liters.

These are equal  

⇒15M x V = 15x 0.48  

Hence, Volume required V = 0.48L =480mL
