The answer would be A) Kyrpton

---

  • Krypton has 36 protons.
  • Argon has 18 protons.
  • Nitrogen has 7 protons.
  • Chlorine​ has 17 protons.

After looking at all of these numbers we can see that the element with the highest number of protons is krypton, at 36 protons.

~Hope I could help! Stay safe!~

A 2.026g sample of a hydrate of sodium carbonate (Na2CO3) is heated to remove water. After heating, the mass of the sample is 0.
OLEGan [10]

Answer:

62.98 % of the sample of hydrate is water

Explanation:

Step 1: Data given

Mass of the sample of a hydrate of sodium carbonate (Na2CO3) = 2.026 grams

After heating, the mass of the sample is 0.750 g

Molar mass H2O = 18.02 g/mol

Step 2: Calculate mass of water

Mass water = mass of hydrate - mass of sample after heating

Mass water = 2.026 grams - 0.750 grams

Mass water = 1.276 grams

Step 3: Calculate mass % percent of water

Mass % of water = (mass of water / total mass hydrate) * 100 %

Mass % of water = (1.276 grams / 2.026 grams) *100 %

Mass % of water = 62.98 %

62.98 % of the sample of hydrate is water

To measure the amount of citric acid (C3 H, oHn a certain candy, an analytical chemist dissolves a 16.00 g sample of the candy i
Naily [24]

Answer:

  • Acid-Base reaction (the reactanct acting as a base is NaOH)
  • mass percent = 1.93%

Explanation:

The reaction that takes place is:

  • C₃H₅O(CO₂H)₃(aq) + 3OH⁻ (aq) → C₃H₅O(CO₂)₃⁻³(aq) + 3H₂O(l)

This is a <em>acid-base reaction</em>, with the citric acid acting as the acid and the <u>sodium hydroxide NaOH acting as the base.</u>

We <u>calculate the moles of citric acid</u> using the information from the titration:

  • 0.0142 L * 0.340 M * \frac{1molAcid}{3molOH^{-}} = 1.609x10⁻³ mol citric acid

Now we <u>convert moles to mass</u> using the acid's molecular weight (192.13g/mol):

  • 1.609x10⁻³ mol citric acid * 192.13g/mol = 0.3092 g citric acid

Finally we calculate the mass percent of citric acid in the sample:

  • 0.3092 g / 16.00 g * 100% = 1.93%

Scientists digging in a cave found an unknown substance. The scientists
Vaselesa [24]

Answer:

By adding heat energy

It changed to gas

Explanation:

A substance whose molecules are moving around each other is a liquid. They are held in shape by very weak intermolecular forces.

For solids, there is no movement because the molecules are held up in a fixed lattice.

Gases molecules moves randomly and independently of one another.

  • When a liquid is heated and it gains heat energy, it changes phase.
  • A phase change to gas can be predicted.
  • This is because there is an increase in the speed of the substances.
