In the chemical formula 2so2, how many total atoms of sulfur (s) are there? 1 2 4

1 answer:

6 0

Sulfur has the coefficient of 2, and nothing else. This indicates Sulfur has 2 atoms.

Oxygen on the other hand, has a subscript of 2, as well as the coefficient of 2. Multiplying those, and you see Oxygen has 4 atoms.

So your answer is 2

Also remember there is a 2 in front of S meaning there are 2 Sulfurs.
If it was S02 it would be 1 Sulfur as there is no number in front of sulfer. 

Remember the number in front of a element, represents how many atoms there are :)

Determine the temperature change when 150. G block of gold is supplied with 1.00 • 10 ^3 J of heat

IceJOKER [234]

Answer:

∇T = 51.68°C

Explanation:

Mass = 150g

Heat Energy (Q) = 1.0*10³J

Change in temperature ∇T = ?

Q = mc∇T

Q = heat energy

M = mass

C = specific heat capacity of the gold = 0.129j/g°C

∇T = change in temperature

Q = Mc∇T

1.0*10³ = 150 * 0.129 * ∇T

1000 = 19.35∇T

Solve for ∇T

∇T = 1000 / 19.35

∇T = 51.679°C = 51.68°C

The change in temperature of gold was 51.68°C

<h3>Explanation:</h3>

Step 1: Define

0.965 L

0.0575 M

Step 2: Identify Conversions

Molar Mass of Mg - 24.31 g/mol

Molar Mass of S - 32.07 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of MgSO₄ - 24.31 + 32.07 + 4(16.00) = 120.38 g/mol

Step 3: Find MgSO₄

Substitute [M]: 0.0575 M = x / 0.965 L
Isolate x: 0.055488 mol MgSO₄ = x
Rewrite: x = 0.055488 mol MgSO₄

Step 4: Convert

$\displaystyle 0.055488 \ mol \ MgSO_4(\frac{120.38 \ g \ MgSO_4}{1 \ mol \ MgSO_4} )$ = 6.67959 g MgSO₄

Step 5: Check

We are given 3 sig figs as our lowest. Follow sig fig rules and round.

6.67959 g MgSO₄ ≈ 6.68 g MgSO₄
