Answer:
Mass = 544 g
Explanation:
Given data:
Mass of sulfuric acid formed = ?
Mass of water react = 100.0 g
Solution:
Chemical equation:
SO₃ + H₂O → H₂SO₄
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 100 g/ 18 g/mol
Number of moles = 5.5 mol
Now we will compare the moles of water and H₂SO₄.
H₂O : H₂SO₄
1 : 1
5.56 : 5.56
Mass of H₂SO₄:
Mass = number of moles × molar mass
Mass = 5.56 mol × 98.0 g/mol
Mass = 544 g
Answer: 1) eukaryotic makes up animals, fungi, plants, archaea
2) all cells reproduce through photosynthesis
Answer:
Yes
Explanation:
Qualitative data deals with the properties or qualities of matter. In qualitative studies, the aim is to understand all about the structure and properties of matter.
Some qualitative methods involve the use of radiation. A typical example of such is the X-ray diffraction. XRD is a qualitative method that can reveal the internal structure of a molecule as well as arrangement of atoms which are not hydrogen.
Also radiation is useful in quantitative measurements such as atomic absorption spectroscopy, spectrophotometry, etc.
Answer:
D
Explanation:
wavelength = speed of light/ frequency
= (3 x 10^8 m/s) / (3 x 10^12 Hz)
= 1 x 10^-4 m
Decreased because we all know what happen if we put it with thermal energy
