So first find the moles of the H₂SO₄: Mass = Moles x RFM
so mass = 5.25 x 98 = 514.5g of <span>H₂SO₄</span>
so to find how many Liters of solution use:
Volume = Density x Grams of solute (per kg +1000)
density = 1.266 x 514.5 +1000 = 1917.357kg/l
now use equation: Conc. = Moles / Volume of solution to find the conc.
Conc. = 5.25 x 1917.357 = 4.39Mol⁻¹
Hope that helps
Answer:
The chemical formula is NaClO and consists of one atom of sodium (Na), one atom of chlorine (Cl) and one atom of oxygen (O).
Molecular Weight/ Molar Mass: 74.44 g/mol
Density: 1.11 g/cm³
Explanation:
True
the definition of matter is any substance that has mass and takes up space.
Answer : The time it take to plate out will be, 3.69 minutes.
Explanation :
First we have to calculate the moles of Cr.
Molar mass of Cr = 51.9 g/mol
The cathode half-reaction is,
From this we conclude that,
The number of electrons (n) in the reaction are 3.
The quantity of charge required for the reduction of 1 mole of 
= 
The quantity of charge required for the reduction of 0.0423 mole of = 
Now we have to calculate the time taken.
We know that,
Thus, the time it take to plate out will be, 3.69 minutes.
Global cooling was a hypothesis of the looming cooling of the Earth's surface and atmosphere that would take place over a period of substantial glaciation.
It emerged as a result of a drop of temperature during the period of 1940s and 1970s. After this it was realized that it is not a big threat as global warming.
On the other hand, Global warming is the rise in overall temperature of the atmosphere which is caused by greenhouse effect that is as a result of rise in the levels of greenhouse gas emissions such as CFCs and carbon dioxide.
Global warming is a present threat in the society world over with the rise in temperatures and climatic changes taking place, this is the reason why global warming replaced global cooling.
