Answer:
Explanation:
Heterotrophs cannot make their own food, so they must eat or absorb it. For this reason, heterotrophs are also known as consumers. Consumers include all animals and fungi and many protists and bacteria. They may consume autotrophs or other heterotrophs or organic molecules from other organisms
If 23.2 g of a given gas occupies a volume of 93.2 L at a particular temperature and pressure, what
mass of the gas occupies a volume of 10.4 L under the same conditions?
Answer:
2.59g
Explanation:
Using Avagadro's law equation as follows:
V1/n1 = V2/n2
Where;
V1 = initial volume (litres)
V2 = final volume (litres)
n1 = first amount of gas in grams
n2 = second amount of gas in grams
According to the information provided in this question, v1 = 93.2L, v2 = 10.4L, n1 = 23.2 g, n2 = ?
Using V1/n1 = V2/n2
93.2/23.2 = 10.4/n2
Cross multiply
93.2 × n2 = 23.2 × 10.4
93.2n2 = 241.28
n2 = 241.28/93.2
n2 = 2.588
n2 = 2.59g
The mass of the gas is 2.59g that occupies a volume of 10.4 L under the same conditions.
Avogadro's law equation:V₁/n₁ = V₂/n₂
Where
V₁ = initial volume (litres)
V₂ = final volume (litres)
n₁ = first amount of gas in grams
n₂ = second amount of gas in grams
Given:
V₁ = 93.2L,
V₂ = 10.4L,
n₁ = 23.2 g,
To find:
n₂ = ?
On substituting the values:
93.2/23.2 = 10.4/n₂
93.2 * n₂ = 23.2 * 10.4
93.2* n₂ = 241.28
n₂ = 241.28/93.2
n₂ = 2.588
n₂ = 2.59g
Thus, the mass of the gas is 2.59g.

Answer:
shift to restore equilibrium
Explanation:
Le Châtelier's Principle states that when a stress is applied to a system at equilibrium, the system will respond by shifting in the direction (either towards the products or reactants side) that opposes/ minimizes the effect of the stress.
Note that although the system tries to restore equilibrium, this equilibrium is a new equilibrium.
Equilibrium is the state of a reversible reaction when:
• two opposing reactions occur at the same rate;
• the concentrations of reactants and products are constant

help !!! pretty please ❤️
Answer:
See below!
Explanation:
To find the symbol of the element, you have to use the periodic table.
The mass number is the number of protons and neutrons in the atom.
The atomic number is the number of protons in the atom.
You can find the number of protons from the periodic table.
You can find the neutrons by subtracting the mass number by the number of protons in the atom.
Unless you have an ion, you will have the same amount of electrons as you do protons.
To write in nuclear notation, you write the chemical symbol with the mass number and atomic number shown in the attachment. It is preferable to have the mass number and atomic number directly above each other.
Finally, what mass of Na2HPO4 is required? Again, assume a 1.00 L volume buffer solution. Target pH = 7.49 Acid/Base pair: NaH2PO4 Na2HPO4 PK = 7.21 [Na2HPO4] > [NaH2PO4] (NaH2PO4) = 0.100 M 12.0 g NaH2PO4 required [base] [acid] = 1.91 [Na2HPO4) = 0.191 M. There is 1.00 L of solution.

What kind of mixture is frozen
yogurt with sprinkles, fudge, and
gummy bears? How can you tell
Answer:
a heterogeneous mixture
Explanation:
I can see all of the different parts of the frozen yogurt, and if I were to pick up a gummy bear, it would come out. Thus, it is not fully/completely mixed with the other components.
It is a heterogenous mixture.
What is the difference between Homogeneous and Heterogeneous Mixtures ?A type of mixtures where all the components are mixed uniformly called as homogeneous mixture.
Here the Particles are distributed in an uniform way, called as solution. Example rainwater, vinegar.
It consist of one phase, It can’t be separated out physically
In heterogenous mixture, all the components are completely and equally mixed, particles can be seen under a microscope.
Here the Particles are distributed non-uniform way, Example: seawater, pizza, etc.
It can be in two or more phases and separated out physically
