Answer : The products of this reaction are, and
Explanation :
First we have to write the balanced chemical reaction.
In this reaction, 1 mole of copper nitrate react with the 2 moles of sodium hydroxide to give 1 mole of copper hydroxide and 2 moles of sodium nitrate.
This reaction is a double displacement reaction.
Double displacement reaction : A type of reaction in which a positive cation and a negative anion of two reactants react to exchange their places to form two new products.
The general representation of this reaction is,
(X and A are the cations, Y and B are the anions)
Hence, the products of this reaction are, copper hydroxide, and sodium nitrate,
Answer:
a) The module's acceleration in a vertical takeoff from the Moon will be
b) Then we can say that a thrust of won't be able to lift off the module from the Earth because it's smaller than the module's weight (
).
Explanation:
a) During a vertical takeoff, the sum of the forces in the vertical axis will be equal to mass times the module's acceleration. In this this case, the thrust of the module's engines and the total module's weight are the only vertical forces. (In the Moon, the module's weight will be equal to its mass times the Moon's gravity acceleration)
Where:
thrust
module's mass
moon's gravity acceleration
module's acceleration during takeoff
Then, we can find the acceleration like this:
The module's acceleration in a vertical takeoff from the Moon will be
b) To takeoff, the module's engines must generate a thrust bigger than the module's weight, which will be its mass times the Earth's gravity acceleration.
Then we can say that a thrust of won't be able to lift off the module from the Earth because it's smaller than the module's weight (
).
