Answer:
<em>D is the answer</em>
Explanation:
First of all, conservation is when you conserve resources, or use them less, to be better for the environment. Using a gas powered car does not, as carbon monoxide and other toxic gases are sent into the atmosphere. Using a disposable bag is bad because the plastic is sent away to the environment every time you shop. Leaving water running when you brush your teeth wastes water and is bad for the environment. Recycling aluminium cans and glass bottles is good for the environment, and is conserving resources because the cans and bottles are reused, so instead of wasting, you are reusing.

Answer:
Mg₃(PO₄)₂
Explanation:
Note: The phosphate ion is PO₄³⁻
3Mg⁺² + 2PO₄³⁻ => Mg₃(PO₄)₂
Answer: look on my page ill help you with this one but im not sure if it would be right because i dont really understand myself but look on mine
Explanation:
E. Carbon dioxide isn't a product, it's taken in by the plant, oxygen is a product.
A lead ball added to a graduated cylinder containing 30.8 ml of water, causing the level of the water to increase to 89.9 ml, has a volume of 59.1 ml.
Volume is defined as the amount of space that matter occupies. There are three different ways to find the volume:
1) Volume by Space - by measuring its physical dimensions
2) Volume by Density and Mass - by dividing its weight by its density
3) Volume by Displacement - by measuring the volume displaced when immersed in a liquid or gas
To solve for the volume of the lead ball, we can use the displacement method by subtracting the initial volume from the final volume.
If the level of the water increased from 30.8 ml to 89.9 ml upon adding the lead ball, the displaced volume is:
volume = final volume - initial volume
volume = 89.9 - 30.8
volume = 59.1 ml
Hence, the volume of the lead ball, using displacement method, is 59.1 ml.
