The chemical formula below shows how salt is produced.HCl + NaOH -----> NaCl + H2O

Which substances are the reactants?

Answers

Answer 1
Answer:

Answer:

reactants: HCl and NaOH

Explanation:

A chemical reaction or equation can be explained with reference of two components: the reactants and products

Reactants are atoms, molecules or ions that are present of the left side of the equation. These could either be a single entity  which can break or decompose under a given conditions or they could combine with other entities appropriately to form new molecules, atoms, ions etc. These new molecules occupy the right side of the reaction and are termed as Products.

The given reaction is and acid-base neutralization reaction

HCl + NaOH -----> NaCl + H2O  

Reactants:

HCl, hydrochloric acid

NaOH, sodium hydroxide

Products:

NaCl, sodium chloride

H2O, water
Answer 2
Answer: hydrochloric acis and sodium hydroxide

Do x-rays travel slower than infrared

Answers

No, x-rays do not travel slower than infrared radiation or even the opposite. Both are travelling in vacuum therefore they travel at same speed. They differ in the frequency of the electromagnetic waves.

Determine the percent composition of chlorine (Cl) in sodium chloride (NaCl). .

Answers

Answer:

\% Cl=61.65\%

Explanation:

Hello,

In this case, chlorine's percent composition is given by the shown below formula:

\% Cl=(n_(Cl)m_(Cl))/(M_(NaCl))*100\%

Whereas n_(Cl) accounts for the number of chlorine atoms into the NaCl, m_(Cl) for chlorine's atomic mass and M_(NaCl) for sodium chloride's molar mass, therefore, the percent composition of chlorine turns out:

\% Cl=(1*35.45)/(58.45)*100\%=61.65\%

Best regards.
It's (grams-of-Cl/total-grams)(100), so (35.45g/58.44g)(100) = 60.66% Cl. Hope this helps!

Which of the following observations led physicist James Chadwick to perform experiments that eventually led to the discovery of the neutron?A. Protons alone were not able to account for the density of an atoms nucleus.

B. Atomic nuclei possess shells similar to the electron shells of atoms.

C. Some atoms contained more protons than electrons.

Answers

The correct answer is letter C. James Chadwick confirmed the existence of neutrons.In his experiment, he was able to show that the particles that were ejected had no electrical charge but had almost the same mass as the proton. These particles were, of course, neutrons.

Part AGiven the following equation, N2O(g) + NO2(g) → 3 NO(g) ΔG°rxn = -23.0 kJ

In addition, predict under what temperatures (all temperatures, low temperatures, or high temperatures), if any, the reaction in part D will be spontaneous
A) The reaction is spontaneous at all temperatures.
C) The reaction is spontaneous at high temperatures.
D) The reaction is nonspontaneous at all temperatures.

Answers

The correct answer for the question that is being presented above is this one: "C) The reaction is spontaneous at high temperatures." 
Since dH is positive and dS ~ 0 then -TdS ~ 0, meaning dG will always be greater than 0 so the reaction is spontaneous at high temperatures.
