Explanation:
Some consumers, like lions, do not eat plants or any other producers. They only eat other animals. lions obtain the carbon they need by eating animals that have carbon-based molecules stored in their bodies and the correct option is option 1.
What are Consumers?Heterotrophs are known as consumers because they consume producers or other consumers. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.
Heterotrophic living organisms include all animals and fungi, some protists and bacteria, many types of parasitic plants.
Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level.
Therefore, Some consumers, like lions, do not eat plants or any other producers. They only eat other animals. lions obtain the carbon they need by eating animals that have carbon-based molecules stored in their bodies and the correct option is option 1.

Susan is investigating physical changes. To do this, she places some ice into a large bowl and seals it with a lid. She leaves the bowl on the counter for several hours until all of the ice has melted. Using a balance, Susan determines that the mass of both the water and the ice are equal. Why is the mass of the ice and the water the same? (SC.8.P.9.1)
Answer:
No mass loss
Explanation:
The mass of ice and the water in the different state are equal because the same of quantity of matter is present in both state of matter of matter.
In essence, the mass of the physical change process is conserved. When mass is conserved, matter is neither created nor destroyed but can be changed from one form to the other. This is in compliance with the law of conservation of matter. So, no mass was lost in the physical change process and the mass will remain the same.A nitrogen molecule (N2) has one triple bond.

How many moles are in a sample of 9.47 x 1024 atoms of argon (Ar)? (Show your calculations for full credit. Correct answers will only receive partial credit.)
Your answer:
Answer:
15.73 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{9.47 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 15.730897...[/tex]
We have the final answer as
15.73 molesHope this helps you
Answer:
15.7 moles of Ar
Explanation:
Given data:
Number of atoms = 9.47 ×10²⁴ atoms
Number of moles of Ar = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
9.47 ×10²⁴ atoms × 1 mole / 6.022 × 10²³ atoms
1.57×10¹ mol
15.7 mol

The correct Lewis dot structure for [tex]BeH_2[/tex] is Be : H : H
What does the Lewis dot structure show?The Lewis dot structure shows the valence electrons as dots. The valence electrons of beryllium are shown as 2 dots on the left side of the atom.
The central atom, beryllium, has 2 valence electrons where each hydrogen atom has 1 valence electron. To form a stable molecule, beryllium shares its 2 valence electrons with the 2 hydrogen atoms, each of which shares its 1 valence electron with beryllium which gives each atom a full outer shell of electrons.

Given a balanced chemical equation it is always possible to determine
A)
the physical state of the products and reactants
B)
whether a reaction will or will not take place
C)
the relative number of moles taking part in the reaction
D)
the conditions necessary for the reaction to take place
Answer:
C) the relative number of moles taking part in the reaction
Explanation:
From a balanced chemical equation, it is always possible to determine the relative number of moles taking part in a chemical reaction.
The number of moles is the amount of the reacting specie that makes up a chemical reaction.
In balanced chemical equation, the number of moles of reactants and products must be the same. From this understanding, we can determine the amount of reactants and products needed for a chemical reaction to take place.How many molecules are equal to 3.25 moles of carbon dioxide?
Answer:

0.45 g of hydrated sodium carbonate crystals were heated until 3.87 of anhydrous power remained.
How many moles of water are there in one mole of hydrated salt?
Formula of hydrated sodium carbonate : Na₂CO₃.10H₂O, so moles of water in one mole of hydrated salt = 10
Further explanationHydrate is a compound that binds water (H₂O), usually in the form of crystals/ solids
If these compounds are dissolved in water or heated, the hydrates can decompose:
Example: X.YH₂O (s) → X (aq) + YH₂O (l)
The formula for the hydrated compound contains: YH2O
The mole ratio shows the ratio of the coefficients of the hydrate compound
10.45 hydrated sodium carbonate(Na₂CO₃.xH₂O) were heated until 3.87 of 3.87of anhydrous (Na₂CO₃) remained, so
mass H₂O released :
[tex]\tt 10.45-3.87=6.58~g[/tex]
mass Na₂CO₃ = 3.87 g
mol ratio Na₂CO₃(MW= g/mol) : H₂O(MW=18 g/mol) =
[tex]\tt \dfrac{3.87}{105,9888}\div \dfrac{6.58}{18}=0.0365\div 0.3655=1\div 10[/tex]

A group of tourists were on an outing when they noticed that precipitation began to fall. The air temperature was 32 degree Fahrenheit. What type of precipitation did they most likely see?
Answer:
The correct answer is - rain.
Explanation:
At 32 degrees c or zero degrees Celsius, droplets of water in the atmosphere do not freeze as it is not the temperature at which water freezes but it is the temperature at which ice melts.
At this temperature the water changes its state, below 32 degrees Fahrenheit the water freezes but in the atmosphere, it not freezes necessarily and remains in the liquid state and called super-cooled liquid or water. Above this temperature, water in liquid state.
Thus, the precipitation is in the form of rain.
