Answer:

Atoms are composed of extremely small particles that are too small to be seen with an optical microscope.

Size at the atomic level is measured on the nanoscale.

Atoms are made of three subatomic particles - protons, neutrons, and electrons.

Protons:

positively charge
located in the nucleus

Neutrons:

no charge (neutraly charge)
located in the nucleus

Electrons:

negatively charged
located around the nucleus

Atomic number (Z) = the number of protons in the nucleus of an atom.

Suppose the fluid in the stomach of a man suffering from indigestion can be considered to be 200.ml of a 0.033 m hcl solution. w

Ede4ka [16]

HCl + NaHCO3 = NaCl + H2O + CO2

We have 0.033*0.2 = 0.0066 mol of Hcl

According to reaction we need the same amount of NaHCO3
M(NaHCO3) = 23+1+12+48=84g/mold
m = 0.0066mol * 84g/mol = 0.5544g

Using Dimensional Analysis
Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<h3>Explanation:</h3>

<u>Step 1: Define</u>

103.4 g H₂S (Sulfuric Acid)

<u>Step 2: Identify Conversions</u>

Avogadro's Number

Molar Mass of H - 1.01 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of H₂S - 2(1.01) + 32.07 = 34.09 g/mol

<u>Step 3: Convert</u>

Set up: $\displaystyle 103.4 \ g \ H_2S(\frac{1 \ mol \ H_2S}{34.09 \ g \ H_2S})(\frac{6.022 \cdot 10^{23} \ molecules \ H_2S}{1 \ mol \ H_2S})$
Multiply: $\displaystyle 1.82656 \cdot 10^{24} \ molecules \ H_2S$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 4 sig figs.</em>

1.82656 × 10²⁴ molecules H₂S ≈ 1.827 × 10²⁴ molecules H₂S

What subatomic particle is responsible for combining the atoms together to form a new substance?

Tanya [424]

The answer to this question would be: electron

When atoms bind together, that mean they shared at least one electron. The electron is located on the outer side of the atoms so the electron from an atom can collide with other electrons from another atom. The protons and neutron can't make bind because it was in the middle of the atom and won't collide each other.
