Answer:
The atom
Explanation:
2) 0.101 kg Ti into atoms
Answer:
The answer to your question is below
Explanation:
1) 0.143g of Mg into atoms
- Look for the atomic number of Magnesium in the Periodic table
Atomic number = 24.31 g
-Use the Avogadro's number to find the number of atoms
24.31g ------------------- 6.023 x 10²³ atoms
0.143 g ----------------- x
x = (0.143 x 6.023 x 10²³) / 24.31
x = 8.613 x 10²² / 24.31
x = 3.54 x 10²¹ atoms
2) 0.101 kg of Ti into atoms
-Look for the atomic number of Titanium in the Periodic table
Atomic number = 47.87 g
-Use the Avogadro's number to find the number of atoms
47.87 g --------------------- 6.023 x 10²³
101 g ---------------------- x
x = (101 x 6.023 x 10²³) / 47.87
x = 6.08x 10²⁵ / 47.87
x = 1.27 x 10²⁴ atoms
The universe is expanding is as the galaxies are moving away from each other, and the temperature of the universe is decreasing. Therefore, option (1) is correct.
First scientists theorized that as the universe is expanding and its temperature has gradually decreased. The universe has been expanding since the Big Bang and, as it expands, it’s temperature cooling down.
The temperature of the universe can be measured by looking at the cosmicmicrowave background (CMB). The temperature an be estimated by the thermal radiation left over from the BigBang.
The CMB scientists have been investigating that its temperature has been dropping off gradually as our universe expands out and the current average temperature of the cosmos is estimated about 2.73 Kelvin.
The point of the Big Bang from the Big bang theory is described as densesingularity and infinitely hot. The energy from the Big Bang distributed as the universe expands and gives the cooling effect.
But new research suggests otherwise that the temperature of the earth is actually increasing as it expands. Therefore, the temperature of universe increasing with its expansion.

b. False
the answer is false cause i tried true first and got it wrong.
Answer:
False
Explanation:
Not all solids have an orderly internal structure, although some do which are called crystalline solids. Some examples are metals and table salt. Solids without a orderly internal structure are called amorphous solids. Examples of this are glass, plastics, and rubber.
