Yes , I agree with the statement water contains minerals
<u>Explanation:</u>
- When LaShawna saw the steam, she said that the water must contain a lot of minerals and the statement is true.
- Most of the water comes from the underground supply and they undergo some cleaning process and stuff.
- Usually, mineral water comes from natural underground water supply and the springs.
- Chemical compounds like Calcium, potassium, sodium, iron are present in water.
- Magnesium plays an essential function in maintaining blood supply and high mineral content water helps us to prevent or lower the heart-related disease.
- Calcium is the building block for maintaining the bone's health.
The balanced reaction is as follows;
BiCl₂ + Na₂SO₄ --> 2NaCl + BiSO₄
this is a double displacement reaction
the oxidation number of Bi is +2 in both BiCl₂ and BiSO₄
oxidation number of Cl is -1 in both BiCl₂ and NaCl
oxidation number of Na is +1 in both Na₂SO₄ and NaCl
oxidation numbers of elements in SO₄²⁻ remains the same in both compounds.Therefore the oxidation state in any of the elements in the reaction doesn't change. Neither of the elements show an increase or decrease in the oxidation numbers .
Answer for this question is no element decreases its oxidation number.
Explanation:
Electromagnetic wave Wavelength
(1) Microwave = 1 m to 1 mm = 
to 
(2) Ultraviolet = 10 nm to 400 nm
(3) Radio waves = 1 mm to 100 km = to 
(4) Infrared = 700 nm to 1 mm
(5) X-ray = 0.01 nm to 10 nm
(6) Visible = 400 nm t0 700 nm
a) In order of increasing wavelength:
: 5 < 2 < 6 < 4 < 1 < 3
b) Frequency of the electromagnetic wave given as:
= frequency
= Wavelength
c = speed of light
So, the increasing order of frequency:
: 3 < 1 < 4 < 6 < 2 < 5
c) Energy(E) of the electromagnetic wave is given by Planck's equation :
So, the increasing order of energy:
: 3 < 1 < 4 < 6 < 2 < 5
A chemical substance has the characteristics that it cannot be separated by physical methods. Seawater and milk can be separated by sedimentation, and air has different components depending on other aspects (such as elevation). Only ammonia is a substance. (thus it can have a formula: NH<span>3)</span>
