Answer:
D. Malleable, conducts electricity, high melting point, giant structure, metallic lattice
Explanation:
Copper is a metal with an atomic number of 29. This metal is soft and reddish in color which explains why it is very malleable(beaten to form various shapes without breaking).
All metals are good conductors of electricity including copper which is also a metal. Metals generally are insoluble in water. Copper also has a high melting point which is a characteristic of metals due to their giant structure and metallic lattice which makes it difficult to be broken down.
Answer: Sustainable living
Explanation: It is a lifestyle by which an individual uses natural resources only as much as is necessary, which means in limited quantities, and thus reduces the general enormous exploitation of these resources. In this way, the needs of the individual are met and resources are put to use for generations to come. It also refers to personal resources as well as Earth resources in general.
It is obvious from today's point of view that if food was produced only as much as needed, it would mean not throwing away food, everyone, both those who could otherwise afford food and those who are now starving, would be fed up.
With the reduction of production not only of food but also of other necessities, that is, with production to meet the needs and not beyond, there would be less pollution and less emission of harmful hags and greenhouse effect.
Answer:
The coefficients are 2 for H₂O and 1 for Ca(OH)₂.
Explanation:
Let's consider the following reaction.
Ca(OH)₂(aq) + 2 HCl(aq) → CaCl₂(aq) + 2 H₂O(l)
According to the balanced equation, the molar ratio of H₂O to Ca(OH)₂ is 2:1. Using this conversion factor, we have the following proportion:
moles Ca(OH)₂. (2 mol H₂O ÷ 1 mol Ca(OH)₂) = moles H₂O
