Answer:
the moon but mass stays the same
Explanation:
Answer:
3.01×10²⁶ molecules
Explanation:
From the question given above, the following data were obtained:
Mass of H₂ = 1 Kg
Number of molecules =?
From Avogadro's hypothesis,
1 mole of H₂ = 6.02×10²³ molecules
But 1 mole of H₂ = 2 × 1 = 2 g
Now, we shall determine the number of molecules present in 1 Kg (i.e 1000 g) of H₂ as follow:
From Avogadro's hypothesis,
2 g of H₂ = 6.02×10²³ molecules
Therefore,
1000 g of H₂ = 1000 × 6.02×10²³ / 2
1000 g of H₂ = 3.01×10²⁶ molecules
Thus, the number of molecules present in 1 Kg (i.e 1000 g) of H₂ is 3.01×10²⁶ molecules
Answer:
Weathering, Erosion
Explanation:
Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.
Tree root systems have a handful of large roots that branch out into a network of smaller roots that often extend out far beyond their branches do. These root systems prevent erosion by holding the soil in place and improving drainage which helps water get absorbed into the soil instead of just running over the top.
Hope this helps

Given what we know, the most appropriate way to find the concentration of orange candies is to take the exact number of orange candies and divide it by the total number of candies present.
<h3>Why is this the best method?</h3>
- This is the best method because it allows us to obtain a decimal value.
- This value will represent the percentage of candies in the total that are orange.
- In order to pass this decimal into a percent value, all we have to do is multiply by 100.
Therefore, we can conclude that by taking the total amount of orange candies and dividing by the total number of candies, we can obtain a decimal to illustrate the percent of total candies that are orange.
