Answer:
1. Delete lion, bison, reindeer, and giraffe
2. Delete cactus, oak, evergreen,
Explanation:
1. Lions live in the African savanna, bison live in open fields with lots of grass, reindeer live in Antarctica and other very cold places, and giraffes also live in the areas of the African savanna where there are trees.
2. Cacti live in the desert, oaks and evergreens live in open grassy areas.
Hope this helps
Answer:
2.85moles of oxygen gas
Explanation:
Given parameters:
Volume of oxygen gas = 63.8L
Unknown:
Number of moles = ?
Solution:
We assume that the gas is under standard temperature and pressure. To find the number of moles, use the expression below:
1 mole of a gas at STP occupies a volume of 22.4L
So;
63.8L of oxygen gas will take up a volume of
= 2.85moles of oxygen gas
Answer:
You use the fact that 1 mole of any substance contains exactly 6.022⋅1023 atoms or molecules of that substance - this is known as Avogadro's number. In your case, 1 mole of gold will have exactly 6.022⋅1023 atoms of gold.
So it would be answer 3690 atoms or 3.60x1025
Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is,
6CO₂ + 6H₂O + light energy --> C₆H₁₂O₆ + 6O₂
This process occurs in the chloroplasts of the plant, using light energy to split water molecules into oxygen and hydrogen. The oxygen is released into the atmosphere while the hydrogen combines with carbon dioxide to form glucose. This glucose is then converted into other compounds, such as cellulose, which the plant uses for energy.
The equation of photosynthesis shows how plants use carbon dioxide and water, combined with light energy from the sun, to produce glucose and oxygen. This process is crucial for life on Earth, as it is the primary way that plants and other photosynthetic organisms convert carbon dioxide into oxygen.
The process of photosynthesis is closely related to the carbon cycle, as it helps to keep the levels of CO₂ in the atmosphere balanced. Photosynthesis removes carbon from the atmosphere and stores it in the form of organic compounds, such as glucose.
As plants use glucose for energy, they release some of this carbon back into the atmosphere in the form of CO₂. This process helps to maintain a steady balance of CO₂ in the atmosphere, which is crucial for life on Earth.

<span>The total number of nodes = n-1.
a) In your case for the 5 d orbital 5 - 1 = 4 nodes.
b) The l quantum number for a d orbital is 2. Therefore you will have 2 angular (planar) nodes.
c) You have 4 nodes, 2 of which are angular. Therefore, you will also have 2 radial nodes.</span>
