Answer:
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
As is a stronger acid than water , it will lose ions and water will gain ions.
The balanced chemical reaction will be :
where (aq) = aqueous
(l) = liquid
2KMnO4 + 2FeSO4 + 2H2SO4 ->
K2SO4 + 2MnSO4 + Fe2(SO4)3 + 2H2O
D. The answer is Finley, Xander, then Max.
Answer:
4.55 m
Explanation:
Given data
- Frequency (ν): 66.0 MHz = 66.0 × 10⁶ Hz = 66.0 × 10⁶ s⁻¹
- Speed of light (c): 3.00 × 10⁸ m/s
We can determine the wavelength of the radio waves using the following expression.
c = λ × ν
λ = c/ν
λ = (3.00 × 10⁸ m/s)/66.0 × 10⁶ s⁻¹
λ = 4.55 m
The wavelength of the radio waves is 4.55 m.
Part (a)
0.0095 + 8.5 x 10⁻³
= 9.5 x 10⁻³ + 8.5 x 10⁻³
= (9.5 + 8.5) x 10⁻³
= 18 x10⁻³
= 1.8 x 10⁻²
Answer: 1.8 x 10⁻²
Part (b)
653 + 5.75 x 10⁻⁸
= 6.53 x 10² + (5.75 x 10⁻¹⁰) x 10²
= (6.53 + 5.75 x 10⁻¹⁰) x 10²
= 6.53 x 10²
Answer: 6.53x 10²
Part (c)
850,000 - 9.0 x 10⁵
= 8.5 x 10⁵ - 9.0 x 10⁵
= - 0.5 x 10⁵
= - 5.0 x 10⁴
Answer: -5.0 x 10⁴
Part (d)
(3.6 x 10⁻⁴) * (3.6 x 10⁶)
= (3.6*3.6)*(10⁻⁴)*(10⁶)
= 12.96 x 10⁶⁻⁴
= 12.96 x 10²
= 1.296 x 10³
Answer: 1.296 x 10³
