Will give brainly

kicyunya [14]

Answer:

Ch4 + 2O2 ----> CO2 + 2H2O

Explanation:

Ch4 has 4H, 1C

O2 has 2 O2

CO2 has 1 C, 2O

H2O has 1 H, 2O

you need to add 2 to O2 to balance it. Add 2 to H2O to balance the H and O

What is the mass of 3.0 x 10^23 atoms of neon

kari74 [83]

Molar mass neon = 20.1797 g/mol

20.1797 g ---------- 6.02x10²³ atoms
? g ------------ 3.0 x 10²³ atoms

mass = 3.0 x 10²³ * 20.1797 / 6.02 x 10²³

mass = 6.054x10²⁴ / 6.02 x 10²³

mass = 10.05 g

hope this helps!

Answer:

1.047 M

Explanation:

The given reaction:

$6Fe^{2+}_{(aq)}+Cr_2O_7^{2-}_{(aq)}+14H^+_{(aq)}\rightarrow 6Fe^{3+}_{(aq)}+2Cr^{3+}_{(aq)}+7H_2O_{(aq)}$

For dichromate :

Molarity = 0.254 M

Volume = 15.8 mL

The conversion of mL to L is shown below:

1 mL = 10⁻³ L

Thus, volume = 15.8 ×10⁻³ L

Thus, moles of dichromate :

$Moles=0.254 \times {15.8\times 10^{-3}}\ moles$

Moles of dichromate = 0.0040132 moles

1 mole of dichromate react with 6 moles of iron(II) solution

Thus,

0.0040132 moles of dichromate react with 6 × 0.0040132 moles of iron(II) solution

Moles of iron(II) solution = 0.02408 moles

Volume = 23 mL = 0.023 L

Considering:

$Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}$

Molarity = 0.02408 / 0.023 = 1.047 M
