Find number atoms in each element?
____ [38]
1. Gypsum has the formula as CaSO₄.2H₂O<span>. Hence, CaSO₄ is bound with two H₂O. CaSO₄ has 1 Ca atom, 1 S atom and 4 O atoms. 2H₂O have 4 H atoms and 2 O atoms.
Hence,
      total Ca atoms = 1
      total S atoms = 1
      total O atoms = 4 + 2 = 6
      total H atoms = 4
      total number of atoms = 1 + 1 + 6 + 4 = 12

</span>2. Cellulose has the formula as C₆H₇O₂(OH)₃. But there are 2 molecules.<span> Hence, to find total atoms in each element, number of atoms should be multiplied by 2 .The elements of the cellulose are C, H, and O. Hence,
      total C atoms = 6 x 2 = 12
      total O atoms = (2 + 3) x 2 = 10
      total H atoms = (7 + 3) x 2 = 20
      total number of atoms = 12 + 10 + 20 = 42
</span>
3. The formula of the antiperspirant is Al₂Cl(OH)₅<span>. It has Al, Cl, O and H as the elements. Hence, the number of atoms in each element can be found as follows;
      total Al atoms = 2
      total Cl atoms = 1
      total H atoms = 1 x 5 = 5
      total O atoms = 1 x 5 = 5
      total number of atoms = 2 + 1 + 5 + 5 = 13</span>

Use the picture of the heliocentric and geocentric models to answer the question below:
xxMikexx [17]

Answer:

Model 1 represents the old geocentric model of the solar system and Model 2 represents the newer heliocentric model of the solar system.

Explanation:

Model 1 has earth in the center, therefore it is geocentric. the geocentric model of the solar system is old. Nobody believes in it anymore because it is scientifically inaccurate.

Model 2 has the sun in the center, therefore it is heliocentric. This is the newer model of the solar system.

what is the molar mass of sucrose C12H22O11 , needed to prepare 500 mL of a sugar solution with a concentration of 0.783 mol.​
BartSMP [9]

Answer:

342g/mol

Explanation:

Molar mass of carbon=12, hydrogen=1 and oxygen=16

therefore C12H22O11=12(12)+22(1)+11(16)

=144+22+176

=342g/mol
