Answer:
C. Bent
Explanation:
Only a bent molecule is polar.
The two bond dipoles do not cancel, so the molecule is polar.
A is wrong. In a linear molecule, the bond dipoles are equal and in opposite directions, so they cancel. The bonds are polar, but the molecule is nonpolar.
B is wrong. In a trigonal planar molecule like that shown below, the resultant of the bond dipoles of the two lower bonds is equal to the upper bond dipole and in the opposite direction. The two dipoles cancel, so the molecule is nonpolar.
D is wrong. A tetrahedral molecule may have polar bonds, but it is a nonpolar molecule. The two bonds on the right have a net dipole to the left, and the two bonds on the left have an equal resultant to the right. The dipoles cancel, so the molecule is nonpolar.
Answer:
Put 15 milliliters (1 tablespoon) of water into the empty soft-drink can. Heat the can on the kitchen stove to boil the water. When the water boils, a cloud of condensed vapor will escape from the opening in the can. Allow the water to boil for about 30 seconds.
Answer:
Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.
The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

Hello!
In this case, for the undergoing chemical reaction at equilibrium:
Which means that pressure-based equilibrium constant is computed via the following equilibrium expression:
Thus, by plugging in the given pressures at equilibrium, the required Kp turns out:
Best regards!
Given that acids burns and the reactions of some metals with acids are violent, you have to protect agains spills and splashes that can seriously harm you: your eyes, your hands, your arms, your feet, even your clothe.
So you shall use:
- Safety glasses (googles)
- Chemical gloves
- Lab coat
- Closed shoes
