Level 3 is the correct answer
Answer:
1.41 g of H₂O
Solution:
The equation for given reaction is as follow,
Cu₂O + H₂ → 2 Cu + H₂O
According to equation,
127 g (2 mole) Cu is produced along with = 18 g (1 mole) of H₂O
So,
10 g Cu produced will generate = X g of H₂O
Solving for X,
X = (18 g × 10 g) ÷ 127 g
X = 1.41 g of H₂O
Answer:
If u use math why It will give u the answer like 3x3=9
Explanation:
Urricanes<span> act as giant heat engines, so it is logical to assume that an </span>increase<span> in sea surface temperatures (SSTs) will make more intense </span>hurricanes<span>. Indeed, there is a general consensus among </span>hurricane<span> scientists that an </span>increase<span> in SSTs due to global warming, should, in theory, lead to more intense </span>hurricanes<span>.</span>As the storm gets stronger, it gets rounder and the eye begins to form. Really stronghurricanes<span> have very clear round eyes like the one in this picture. The most intense winds in a </span>hurricane are in the thunderstorms that form the eyewall. Tropical cyclones strengthen when all of the conditions are right for them.
The given question is incomplete. The complete question is:
A chemist prepares a solution of barium chloride by measuring out 110 g of barium chloride into a 440 ml volumetric flask and filling the flask to the mark with water. Calculate the concentration in mole per liter of the chemist's barium chloride solution. Round your answer to 3 significant digits.
Answer: Concentration of the chemist's barium chloride solution is 1.20 mol/L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,
n = moles of solute
= volume of solution in L
moles of
(solute) = 
Now put all the given values in the formula of molality, we get

Therefore, the molarity of solution is 1.20 mol/L
