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

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.

2. Describe how a cold front affects weather.
Answer:
Cold fronts can produce dramatic changes in the weather.
Explanation: They move fast, up to twice as fast as a warm front. As a cold front moves into an area, the heavier (more dense) cool air pushes under the lighter (less dense) warm air, causing it to rise up into the troposphere.

Why do metal boats float?
Answer:
I hope this will help you
Explanation:
The air that is inside a ship is much less dense than water. That's what keeps it floating! The average density of the total volume of the ship and everything inside of it (including the air) must be less than the same volume of water.

Lithium forms ions with a charge of lt Oxygen forms ions with a charge of 2- in the ionic compound lithium oxide, how many
atoms of lithium will there be if there is 1 atom of oxygen?
HELP ME
Answer:
There are 2 lithium atoms in the ionic compound lithium oxide, Li₂O
Explanation:
The charge of ions formed by lithium = 1⁺
The charge of ions formed by oxygen = 2⁻
In the ionic compound lithium oxide having 1 atom of oxygen, we have;
For the compound to be electronically neutral, the sum of the charges of the atoms in the ionic compound is zero
The charge of 1 atom of oxygen in the lithium oxide compound + The charge of the 'n' number of lithium atoms in the lithium oxide compound = 0
∴ 2⁻ + n × 1⁺ = 0
n × 1⁺ = 0 - 2⁻ = 2⁺
n = 2⁺/(1⁺) = 2
n = 2
The number of lithium atoms in the lithium oxide compound, n = 2
Therefore, there are two lithium atoms in the ionic lithium oxide (Li₂O) compound

Answer:
See Explanation
Explanation:
moles of NH₃ = 11.9g/17.03 g/mol = 0.699 mole
moles of CN₂OH₄ = 1/2(0.699) mole =0.349 mole
Theoretical yield of CN₂OH₄ = (0.349 mole)(60 g/mole) = 20.963 grams
%Yield = Actual Yield/Theoretical Yield x 100%
= 18.5g/20.963g x 100% = 88.25%
Answer:
same process as last solution I did for you except the mole ratio isn't 1:1 here it is 2:1 so you diveide the moles of NH3 by 2 to get the urea moles
here I got 88.16% yield

After Dalton's proposed atomic theory, several atomic models were developed. Which model was the first propose the existence of
small, dense nucleus?
Answer: Rutherford's model was the first propose of the existence of small, dense nucleus's.
Explanation: The atom, as described by Ernest Rutherford, has a tiny, massive core called the nucleus. The nucleus has a positive charge. Electrons are particles with a negative charge. Electrons orbit the nucleus. The empty space between the nucleus and the electrons takes up most of the volume of the atom.

Balance this equation. Pb(NO3)2(aq)+NaCl(aq) -> NaNO3(aq)+PbCl2(s)
Answer:
Pb(NO3)2(aq) + 2NaCl(aq) -> 2NaNO3(aq)+PbCl2(s)
Explanation:
Pb(NO3)2(aq)+NaCl(aq) -> NaNO3(aq)+PbCl2(s)
This is how it starts out.
Left:
2 NO3s1 Pb1 Na1 ClRight
1 Na1 NO31 Pb2 ClSo the place to start with this equation is to bring the Cls up to 2
Pb(NO3)2(aq)+2NaCl(aq) -> NaNO3(aq)+PbCl2(s)
But the Nas are now out of kilter.
Pb(NO3)2(aq)+ 2NaCl(aq) -> NaNO3(aq)+PbCl2(s)
Now the right has a problem. There's only 1 Na
Pb(NO3)2(aq) + 2 NaCl(aq) -> 2NaNO3(aq)+PbCl2(s)
Check it out. It looks like we are done.
The molar mass of two equally sized samples of unknown gaseous compounds is shown in the table. Molar Mass Comparison Gas Molar Mass A 17 g/mol B 36.5 g/mol Which statement describes the density and diffusion of both gases at STP? Gas A has a higher density and diffuses faster than Gas B. Gas A has a higher density and diffuses slower than Gas B. Gas A has a lower density and diffuses faster than Gas B Gas A has a lower density and diffuses slower than Gas B.
Answer:
Effusion is the process of a gas being poured out through a hole diametrically smaller than the structural exit of the container.
A lighter gas effuses faster than a heavier gas.
Thus gas A has a lower density and effuses slower than Gas B.
Explanation:
The gas with a lower molar mass will have a lower density and diffuses at a slower rate. Thus gas A has a lower density than gas B and diffuses slower than gas B.
Three points should be noted here;
The density of any substance is related to the molar mass.[tex]D=M/V[/tex], where [tex]D[/tex] is the density, [tex]M[/tex] is the mass and [tex]V[/tex] is the volume of the substance.The density of the gas is directly proportional to the molar mass of the gas.Hence the gas A has lower density and the gas B has higher density as the molar mass of A is [tex]17 g/mol[/tex] and of B is [tex]36.5 g/mol[/tex].
About Diffusion please note the below points;
Diffusion is the process of movement of a substance from the area of higher concentration to the area of lower concentration.The gas with a smaller mass will diffuse slower in rate than the gas with a higher mass.Hence the gas A diffuses slower in rate than gas B.
Thus the correct answer is "Gas A has a lower density and diffuses slower than Gas B".

Oxidation numbers of oxygen in H2PO4 and H2O2 is_____ respectively
Answer:
-2 , -1
Explanation:
H2PO4=-1
+1 × 2 + +5 + 4 ×O=-1
7+ 4O =-1
4O= -8
O = -2
H2O2=0
+1 × 2 +2 x O =0
2 + 2O=0
O= -1
(As the oxidation number of Hydrogen is +1 , and we have 2 hydrogen atoms so we multiply by 2 , while the oxidation number of P is +5 in this equation, also the compound as a whole equals -1 , then we do the steps as followed)
(while the other compound as a whole equals zero , and doing steps as followed)

A balloon occupies 175 cm at 25.0 C. What volume will it occupy at 42.5 °C?
175 cm³ instead of 175 cm.
Answer:
297.5 cm³
Explanation:
From the question;
Initial volume; V1 = 175 cm³
Initial temperature; T1 = 25°C
Final temperature; T2 = 42.5°C
From Charles law we can find the volume V2 from the equation;
V1/T1 = V2/T2
Making V2 the subject gives;
V2 = V1 × T2/T1
V2 = (175 × 42.5)/25
V2 = 297.5 cm³
