Answer:
C.) No, because the Moon reflects most of the Sun's light rather than
absorbing it

Extrusive Rocks. Igneous rocks which form by the crystallization of magma at the surface of the Earth are called extrusive rocks. They are characterized by fine-grained textures because their rapid cooling at or near the surface did not provide enough time for large crystals to grow.
Answer:
1.16L can be made
Explanation:
Molarity = Mol / Volume
Volume = Mol / Molarity
Let's determine the moles of salt, with that mass:
130 g FeCl₂ . 1mol / 126.75 g = 1.02 moles of FeCl₂
Volume = 1.02 mol / 0.88 mol/L → 1.16L
1. If you find shielding that blocks gamma radiation,then it will most likely also block the other two types. (as the hardest radiation)
2. When nuclear radiation enters the tube of a Geiger counter, it the excited atoms of the gas contained in the tube. (this type <span>deposits all energy into a single atom)</span>
3 The particles that make up protons and neutrons and are thought to be basic units of matter are <span>quarks.</span>
The theoretical yield of H₂ in grams is =
<u><em> calculation</em></u>
Zn(s) + 2HCl(aq) → ZnCl₂(aq) +H₂
Step 1: find the moles Zn
moles = mass÷ molar mass
from periodic table the molar mass of Zn = 65.4 g/mol
moles is therefore = 25.3 g/65.4 g/mol=0.387 moles
Step 2: use the mole ratio to determine the moles of H₂
from given equation Zn:H₂ = 1:1 therefore the moles of H₂ is also =0.387 moles
Step 3: find theoretical mass of H₂
mass= moles× molar mass
from periodic table the molar mass of H₂ = 1 × 2 = 2 g/mol
mass =0.387 moles × 2 g/mol =0.774 grams
