Q: What type of molecule is carbon dioxide (co2)? Read this paragraph and choose the correct option from the provided answers: For molecules with more than two atoms, the molecular geometry must also be taken into account when determining if the molecule is polar or nonpolar. The Figure below shows a comparison between carbon dioxide and water. Carbon dioxide (CO 2 ) is a linear molecule. The oxygen atoms are more electronegative than the carbon atom, so there are two individual dipoles pointing outward from the C atom to each O atom. However, since the dipoles are of equal strength and are oriented in this way, they cancel each other out and the overall molecular polarity of CO 2 is zero. Choices: - non-linear - planar - filter - linear A:
**Answer**
linear

Q: What glands in the breast secrete milk? Read this paragraph and choose the correct option from the provided answers: The breasts are not directly involved in reproduction, but they nourish a baby after birth. Each breast contains mammary glands, which secrete milk. The milk drains into ducts leading to the nipple. A suckling baby squeezes the milk out of the ducts and through the nipple. Choices: - primordial glands - adrenal glands - fetal glands - mammary glands A:
**Answer**
mammary glands
