The question is incomplete, here is the complete question.
A chemist prepares a solution of copper(II) fluoride by measuring out 0.0498 g of copper(II) fluoride into a 100.0mL volumetric flask and filling the flask to the mark with water.
Calculate the concentration in mol/L of the chemist's copper(II) fluoride solution. Round your answer to 3 significant digits.
<u>Answer:</u> The concentration of copper fluoride in the solution is 
<u>Explanation:</u>
To calculate the molarity of solute, we use the equation:
We are given:
Given mass of copper (II) fluoride = 0.0498 g
Molar mass of copper (II) fluoride = 101.54 g/mol
Volume of solution = 100.0 mL
Putting values in above equation, we get:
Hence, the concentration of copper fluoride in the solution is
Answer:
The answer is "Orion technology"
Explanation:
NASA tested that perhaps the abort system on the Biomechanical properties fires faster than that of the rocket, possibly costing colonists during launch or a crisis. It test is a significant step forward in Agency's plans again for the Artemis space mission, which will pave the way for human missions to The moon. NASA is building a humanoid spacecraft for long-range space missions for the first time in generations. As just a result, they are beginning a new age of space travel. Orion would be used to transport the crew into space as a surveillance vehicle. Also, it helps astronauts to flights and ensures a safe return to orbit in the case of an emergency release.
Answer:
Explanation:
= Half-life of carbon = 5700 years
t = Time at which the remaining mass is to be found = 10400 years
= Initial mass of carbon = 11 g
Decay constant is given by
Amount of mass remaining is given by
The amount of the substance that remains after 10400 years is .
Answer is: 2.NaNO₃.
Balanced chemical reaction of neutralization:
HNO₃(aq) + NaOH(aq) → NaNO₃(aq) + H₂O(l).
Ionic reaction:
H⁺(aq) + NO₃⁻(aq) + Na⁺(aq) + OH⁻(aq) → Na⁺(aq) + NO₃⁻(aq) + H₂O(l).
Net ionic reaction: H⁺(aq) + OH⁻(aq) → H₂O(l).
Neutralization is reaction in which an acid and a base react quantitatively with each other. In this reaction, there are no acids and bases, only salts.
Answer:
Earthquakes are more intense the faster the planet's crust slams together, which explains why the shaking causes so much damage in some of the most populated areas around mountain chains. ... One reason for this connection is that when two plates come together quickly, the area over which an earthquake occurs is larger.Explanation:
