I'd say the answer is D because they need to intake and keep as much water as possible.
The answer is 0.0171468704904. We assume you are converting between moles Mg(OH)2 and gram. This compound is also known as Magnesium Hydroxide. 1 mole<span> is equal to </span>1 moles<span> Mg(OH)2, or 58.31968 grams.</span>
1. Group: Groups shows the number of valence electrons and are shown in columns on the periodic table.
2. Period: Periods show the number of energy levels each element has and are shown in rows on the periodic table (up and down).
3. Blocks are show the amount of orbitals each element has. There is an s block, d block, p block, and f block.
Answer:
In the 150 years since Darwin proposed the theory of evolution by natural selection, a mountain of evidence has accumulated ... How can you know what happened millions of years ago if no one was there to see it? Evidence and observation are the building blocks of all scientific inquiry; evolutionary science is no different
Explanation:
Answer:
d = 0.84 g/cm³
Explanation:
Given data:
Mass of wood = 2.85 g
Volume of water = 20.0 mL
Volume of water + wood = 23.4 mL
Density of wood = ?
Solution:
Volume of wood = (Volume of water + wood ) - Volume of water
Volume of wood = 23.4 mL - 20.0 mL
Volume of wood = 3.4 mL
1 mL = 1 cm³
Density of wood:
d = m/v
d = 2.85 g / 3.4cm³
d = 0.84 g/cm³
