Some items, such as rubber, float on the water, while some items, such as gold, sink in
the water. If an item floats is it more or less dense than the water?
Answer:
If an item is less dense, it floats on the water.
Explanation:
We know this since the more dense something it usually is heavier than if it was less dense. Which ways it down resulting to it sinking.

Plants use sunlight as energy to convert carbon dioxide and water into glucose and oxygen. Which best describes
the reaction?
The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the
products
O The law of conservation of energy indicates the same amount of carbon will be found in the reactants as in the
products
The law of conservation of mass indicates the same amount of glucose will be found in the reactants as in the
products
O The law of conservation of energy indicates the same amount of glucose will be found in the reactants as in the
products
Answer:
The law of conservation of mass indicates the same amount of carbon will be found in the reactants as in the products
Explanation:
The reaction between carbon dioxide and water in the presence of sunlight to produce glucose and water strictly follows the law of conservation of mass.
Let us give the reaction expression:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
According to the law of conservation of mass, matter is neither created nor destroyed but new compounds are formed during a chemical reaction.
From the given reaction expression, we can clearly see that 6 moles of carbon on the reactant side will produce 6 moles of carbon on the product side.
Therefore, the law obeys the law of conservation of mass.
What is the chemical formula for sodium sulfate
Answer:
Na2So4
Explanation:
Na is group 1, so has a charge of 1+
Sulphate’s formula is SO4 2-,
because sulphate has double the charge of Na, you need two Na’s to make it equal.
Therefore it’s Na2SO4

As you move down a group of the periodic table how does the atomic radius of the atoms change
Answer:
An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements. In general, the size of an atom will decrease as you move from left to the right of a certain period.

8. What is the molar mass of carbon dioxide, Co2(g)? How many grams of carbon
dioxide would there be for 3 moles? Explain.
Answer:
CO2 molar mass=44.01g
3 moles CO2 = 132.03g
Explanation:
CO2 molar mass = 12.01+2(16.00)=44.01g
3 moles CO2 * (44.01 g CO2)/(1 mol CO2)=132.03g
(Answer would be different depending on the number of decimals)

Was Dalton's Atomic Theory correct or incorrect and why?
Answer:
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. ... According to Dalton, atoms of different elements combine in simple whole number ratios to form compounds.

115 mL of a 2.35 M potassium
fluoride (KF) solution is diluted with 1.28 L of water. What is the new concentration in molarity?
? M KF
The new concentration : = 0.194 M
Further explanationGiven
115 mL(0.115 L) of a 2.35 M Potassium fluoride (KF)
1.28 L of water
Required
The new concentration
Solution
Dilution is the process of adding solvent to get a more dilute solution.
The moles(n) before and after dilution are the same.
Can be formulated :
M₁V₁=M₂V₂
M₁ = Molarity of the solution before dilution
V₁ = volume of the solution before dilution
M₂ = Molarity of the solution after dilution
V₂ = volume of the solution after dilution
V₂=0.115 + 1.28 = 1.395 L
Input the value :
M₂ = (M₁V₁)/V₂
M₂ = (2.35 x 0.115)/1.395
M₂ = 0.194
Answer: 0.194

____ power is generated from the heat released when uranium atoms split in a process known as fission.
Typically ____
can not be removed from the atom.
A)
electrons
B)
neutrons
C)
protons
D)
tachyons
I took the test it’s PROTONS
Answer:
Protons
Explanation:
Typically protons cannot be removed from the atom. Removing protons from an atom will completely change the atom as it will become another element entirely.
In an atom, protons are held by strong nuclear forces.
Within an atom, protons are the positively charged particles. Together with the neutrons, they are found in the nucleus of an atom. The number of protons within an atom is the atomic number of the atoms and it determines the nature and type of atom it is. Protons cannot be removed from an atom due to the strong binding force holding them together in place.Answer:
protons

A 2.5 L container holds a sample of hydrogen gas at 291 K and 180 kPa.
If the pressure increases to 350 kPa and the volume remains constant, what will the new temperature be?
Round your answer to one decimal place.
Answer:
The new temperature will be 565.83 K.
Explanation:
Gay Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that the pressure of the gas is directly proportional to its temperature. This means that if the temperature increases, the pressure will increase; or if the temperature decreases, the pressure will decrease.
In other words, Gay-Lussac's law states that when a gas undergoes a constant volume transformation, the ratio of the pressure exerted by the gas temperature remains constant:
[tex]\frac{P}{T} =k[/tex]
When an ideal gas goes from a state 1 to a state 2, it is true:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
P1= 180 kPaT1= 291 KP2= 350 kPaT2= ?Replacing:
[tex]\frac{180 kPa}{291 K} =\frac{350 kPa}{T2}[/tex]
Solving:
[tex]T2=350 kPa*\frac{291 K}{180 kPa}[/tex]
T2= 565.83 K
The new temperature will be 565.83 K.
