Answer: 1.14mol
Nitrogen molar mass=14g/mol
N2 molar mass=14*2=28g/mol
31.9g(1/28)=1.14mol N2
Answer:
The salt and sugar as well as the baby power and granulated sugar are the independent variables.
The dependent variable is how it reacts (will it dissolve or not)
Explanation:
C. (-2,-2) is the answer.
<u>Explanation:</u>
When we reflect a point (x, y) across the y-axis, after the reflection, the y-coordinate tends to be the same, however the x-coordinate is changed into its opposite sign.
Here U(2,-2) is reflected across the y-axis then,
the y-coordinate -2 remains the same and the x-coordinate is transformed into its opposite that is the sign of the x-coordinate will be changed as -2.
So the new coordinates of U after reflection will be (-2,-2).
