Molarity of the solution = 0.08 M
Further explanationMolarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution

In sexual reproduction, how many genes does an offspring receive for each trait ♀️
Answer:
Each parent's half of the genes acquired by the offspring. They have two of each chromosome and hence two alleles of each gene, and one acquired from each parent.

If a sample of gas occupies a volume of 6.80 L at 325°C, what will its volume be at
25.0°C if the pressure does not change?
Answer:
3.4L
Explanation:
Given parameters:
Initial Volume of gas = 6.8L
Initial temperature of gas = 325°C = 325 + 273 = 598K
Final temperature = 25°C = 25 + 273 = 298K
Unknown:
Final volume = ?
Solution:
To solve this problem, we apply the Charles's law. It can be expressed as;
[tex]\frac{V1}{T1}[/tex] = [tex]\frac{V2}{T2}[/tex]
V and T are volume and temperature
1 and 2 are initial and final states
Now insert the parameters and solve;
[tex]\frac{6.8}{598}[/tex] = [tex]\frac{V2}{298}[/tex]
2026.4 = 598V2
V2 = 3.4L

The hydra is an organism that reproduces by growing another organism from the sie of its tubular body. What type of asexual reproduction is this?
Answer:
Explanation:
budding
Figure 13.3 (a) Hydra reproduce asexually through budding: a bud forms on the tubular body of an adult hydra, develops a mouth and tentacles, and then detaches from its parent. The new hydra is fully developed and will find its own location for attachment.
what is the ionic compound for sodium oxide
Answer:
Na2O
Sodium Oxide (Na2O)
Explanation:
Sodium oxide (Na2O) is an ionic compound. Its constituent atoms are, respectively, a metal and a non-metal. ... Sodium (Na), as a metal, will attempt to lose electrons to reach an octet state.
The resulting ionic compound, Na₂O, consists of positively charged sodium ions (Na⁺) and negatively charged oxide ions (O²⁻).
The ionic compound for sodium oxide is "sodium oxide" itself. In the ionic compound's formula, the metal (sodium) comes first, followed by the non-metal (oxygen). Sodium is an alkali metal with a charge of +1, and oxygen is a non-metal with a charge of -2.
The chemical formula for sodium oxide is Na₂O.
In this ionic compound:
Sodium (Na) loses two electrons to become Na⁺ (cation).
Oxygen (O) gains two electrons to become O²⁻ (anion).
The resulting ionic compound, Na₂O, consists of positively charged sodium ions (Na⁺) and negatively charged oxide ions (O²⁻).

Describe fusion and explain how fusion and fission are similar and how they are different.
Answer: Fusion and fission are similar in that they both release large amounts of energy. Nuclear fusion is a process in which two nuclei join to form a larger nucleus. Nuclear fission is a process in which a nucleus splits into two smaller nuclei.

Find the Oxidation Number for both Ca and F.
EXPLAIN PLEASE
Answer:
F= -1 (group 7A)
Ca= +2 (group 2)
Explanation:
oxidation #= # electrons atom gains/loses to form chemical bond
>assigned to atoms in oxidation-reduction rxn to indicate ability to donate/ gain e-
> positive oxidation #= loss of e-, negative= gain of e-
rules:
all group 2 elements (ca) have an oxidation state of 2+
group 7A (F)= -1 charge (needs to gain 1 e- to complete octet)

20 ML of a gas at 200 K is heated until the new volume is 55ML what is the final temperature of the gas
Answer:
T2 = 550K
Explanation:
From Charles law;
V1/T1 = V2/T2
Where;
V1 is initial volume
V2 is final volume
T1 is initial temperature
T2 is final temperature
We are given;
V1 = 20 mL
V2 = 55 mL
T1 = 200 K
Thus from V1/T1 = V2/T2, making T2 the subject;
T2 = (V2 × T1)/V1
T2 = (55 × 200)/20
T2 = 550K
is the following true or false every element in the periodic table follows the aufbau principle
Answer:
True
Explanation:
It is true that every element in the periodic table follows the Aufbau's principle.
The principle states that "the sublevels with lower energies are filled up before those with higher energies".
Sublevels do not fill up in numerical order. This is true when writing the electronic configuration of all atoms on the periodic table.Answer:False
Explanation:
Three reasons why friction is needed
Answer:
1:Without friction, we would not be able to stop walking since we would just keep slipping like on ice.
2:Without friction, objects would just slip and fall with a simple blow of air
3:And finally, without friction, we wouldn't be able to use machinery like cars and etc since they would just fly off
Explanation:
Friction can be a useful force because it prevents our shoes from slipping on the pavement when we walk and stops car tires skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding. Sometimes we want to reduce friction.
