Answer:
1528.3L
Explanation:
To solve this problem we should know this formula:
V₁ / T₁ = V₂ / T₂
We must convert the values of T° to Absolute T° (T° in K)
21°C + 273 = 294K
70°C + 273 = 343K
Now we can replace the data
1310L / 294K = V₂ / 343K
V₂ = (1310L / 294K) . 343K → 1528.3L
If the pressure keeps on constant, volume is modified directly proportional to absolute temperature. As T° has increased, the volume increased too
Answer:
The Correct answer would be A.
cellulose-based cell wall that makes these cells sturdy.
Explanation:
Every other option does not make sense mitochondria makes energy through cellular respiration not photosynthesis.
The nucleus is like the brain of a cell, does not use photosynthesis
cellulose is not part of the cytoplasm, it's part of the cell wall
Chloroplast is responsible for photosynthesis
The element is Si (Silicon)
More about Silicon
silicon (Si), a nonmetallic chemical element in the carbon family (Group 14 [IVa] of the periodic table). Silicon makes up 27.7 percent of Earth’s crust; it is the second most abundant element in the crust, being surpassed only by oxygen.
Silicon is a naturally occurring mineral. It's the second-most abundant element on earth after oxygen. Food sources include water, fruits, and vegetables.
Silicon supplements are sometimes used as medicine. It's not clear if silicon has a function in the human body. But there's some evidence it might have a role in forming bone and collagen.
People use silicon for weak bones (osteoporosis), aging skin, and many other conditions, but there is no good scientific evidence to support most of these uses.
Do not confuse silicon with silicone. Silicone is a group of materials resembling plastic that are used to make medical devices.

Answer:
The periodic table
Explanation:
The periodic table can show the atomic number and atomic mass of any atoms easily. To convert grams of water to moles of water, you need to know the atoms that made up water molecules then find out their molecular mass. Water is made of two hydrogens and one oxygen atoms. Then you can find the atomic mass of hydrogens is 1 while oxygen is 16. The molecular mass of water will be 2*1 + 16= 18g/mol.
