ReAcTanTS and PrOducTS

Chemistry
1 answer:
telo118 [61]3 years ago
5 0

Answer:

START and STOP, ReAcTanTS means START, PrOducTS means STOP

Explanation:

1. We find words 'STOP' and 'START'.

2. Let's take a look at the word 'ReAcTanTS'. Enumerate the capital letters from 1 to 5 from left to right, that is,

'1': R,

'2': A,

'3': T,

'4': T,

'5': S.

Notice that if we take a combination of 54213, we obtain a word 'start'. This has, of course, a chemical application. Reactants are the ones we start with in a chemical reaction.

3. Let's take a look at the word 'PrOducTS'. Enumerate the capital letters from 1 to 4 from left to right, that is:

'1': P,

'2': O,

'3': T,

'4': S.

Notice that if we take a combination of 4321, we obtain a word 'stop'. Similarly to the previous word, it also has a direct relationship to the chemical context. Products are formed in a chemical reaction when reactants combine. This is the point where reaction comes to and end and eventually stops if it's a typical one-sided reaction.

What do all the elements in one row of the periodio fable have in common?
Mamont248 [21]

Answer:

Energy levels

Explanation:

Elements in one row of the periodic table have the same energy levels. A row on the periodic table is the horizontal arrangement of elements. These rows are called periods.

There are 7 periods on the periodic table.

  • Each elements on a period begins with an atom having one valence electrons and then ending with completely filled orbitals.
  • Elements in the same period are known to have the same electronic shells which is the energy level.
  • The principal quantum number of their electrons is the same.

In a 28 g serving of cheese curls there are 247mg of sodium. How much sodium is in a 12.5 ounce bag
Marina86 [1]

Answer:

There should be about 3136.9mg of Na in a 12.5oz bag of cheese curls.when rounding if not rounded it would be 3126.04082143mg

Explanation:

12.5oz=354.4g

354.4/28=12.7

12.7*247=3136.9

a drop of gasoline has a mass of 22 mg and a density of 0.754 g/cm^3. What is its volume in cubic centimeters?
Verizon [17]
The density can be calculated using the following rule:
density = mass/volume
therefore,
volume = mass/density

we have the mass=22 mg=0.022 grams and density=0.754g/cm^3

substituting in the above equation, we can calculate the volume as follows:
volume = 0.022/0.754 = 0.0291 cm^3

The mixing of which pair of reactants will result in a precipitation reaction? A. Ba(NO3)2(aq) + Na2CO3(aq) B. NH4Br(aq) + NH4I(
Semenov [28]

Answer:

A. Ba(NO₃)₂(aq) + Na₂CO₃(aq)

Explanation:

  • The reaction between aqueous Ba(NO₃)₂ and Na₂CO₃ is a precipitation reaction.
  • The complete equation for the reaction is;

Ba(NO₃)₂(aq) + Na₂CO₃(aq) → BaCO₃(s) + NaNO₃(aq)

  • Barium carbonate is the precipitate formed during the reaction.
  • All nitrates are soluble in water and all salts of sodium are soluble in water, therefore, Ba(NO₃)₂, Na₂CO3, and NaNO₃ are soluble in water.
  • Precipitation reaction involves reaction of soluble salts to form a precipitate as one of the product.

At which temperature would the molecules in a one
Nastasia [14]

Answer:

-100 K

Explanation:

<em>Kinetic energy is related to temperature.</em> The molecules in water will move faster in warmer temperatures than in colder ones.

100 K is equal to -279.67°F (-173.15°C). So 100 K would have the lowest average kinetic energy.
