lunar eclipe is the answer
Answer:
solar eclipse
Explanation:
When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can only happen when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.

Which of the following compounds contain the largest number of atoms?
Answer:
C
Explanation:
Since they all are 2 mols worth, all you have to do is count the number of atoms in each molecule
H2SO4 contains 2 hydrogen 1 sulfur 4 oxygen = 7 atoms
H2S contains 2 hydrogen and 1 sulfur = 3 atoms
H3PO4 contains 3 hydrogens 1 phosphorus 4 oxygens = 8 atoms
HNO3 contains 1 hydrogen 1 nitrogen and 3 oxygens = 5 atoms

One mole of aluminum contains 6.022 × 10²³ atoms. This number is called Avogadro number. Therefore, 0.55 moles of aluminum contains 3.31 × 10²³ atoms.
What is Avogadro number ?One mole of any substance contains 6.022 × 10²³ atoms. This number is called Avogadro number. One mole of every elements contains Avogadro number of atoms.
Aluminum is 13th element in periodic table. It shows metallic properties as well as some non-metallic properties. The symbol of aluminum is Al. It forms compounds mostly through covalent bonding.
One mole of aluminum contains 6.022 × 10²³ atoms.
Thus, number of atoms in 0.55 moles = 0.55 × 6.022 × 10²³ = 3.31 × 10²³ atoms.
Therefore, the number of Al atoms in 0.55 moles is 3.31 × 10²³ .

2.00 L of a gas is collected at 25.0°C and 745.0 mmHg. What is the volume at 760.0 mmHg
and 273K. someone help i only have 2 mins left
Answer:
1.79 L
Explanation:
Step 1: Given data
Initial volume of the gas (V₁): 2.00 LInitial temperature of the gas (T₁): 25.0 °CInitial pressure of the gas (P₁): 745.0 mmHgFinal volume of the gas (V₂): ?Final temperature of the gas (T₂): 273 KFinal pressure of the gas (P₂): 760.0 mmHgStep 2: Convert T₁ to Kelvin
We will use the following expression.
K = °C + 273.15
K = 25.0 °C + 273.15 = 298.2 K
Step 3: Calculate the final volume of the gas
We will use the combined gas law.
P₁ × V₁ / T₁ = P₂ × V₂ / T₂
V₂ = P₁ × V₁ × T₂ / T₁ × P₂
V₂ = 745.0 mmHg × 2.00 L × 273 K / 298.2 K × 760.0 mmHg = 1.79 L

A. buoyant
B. chemically reactive
C. metallic
D. solid at room temperature
Answer:
B. Chemically reactive
Explanation:
A Chemically reactive element is an element that is likely to combine with another element to form new substances
The reactivity of the element depends on the number of electrons in the outermost energy level and even the distance of the outermost energy level from the nucleus. From the periodic table, Fluorine is the most reactive non-metal while francium is the most chemically reactive metal

How does plastic impact the environment as a result of human activities
Answer:
As a result of human activities, plastic impacts the envionment in negative way that leads to serious environmental danger.
Explanation:
When we don't throw away plastic materials correctly, it causes littering. Well, this can also lead to piles of that, meaning that it is spreading toxins. Littering may also lead to blockages in flowing streams, lakes, river, ground water, big bodies of water, and small bodies of water. This also can contribute to global warming because plastic are made from chemicals that come from the production of fuels like oil, gas, coal and possible more.
