it gets nourishment from the storage tissues in the seeds, when it develops into a young plant with roots, then it takes nutrients from the soil
When a seed is planted, it gets nourishment from the storage tissues in the seeds. The storage tissues could be in the cotyledon, peristem or endosperm. The storage tissue contain carbohydrates proteins,and fats content. When the embryo develops into a young plant with young roots, the plant then draws nutrients from the soil.

What is ideal gas equation?Ideal gas equation gives idea about the behavior of gases at different conditions and it will be represented as:
PV = nRT, where
P = pressure in atm
V = volume in L
n = moles of gas
R = universal gas constant = 0.082 L.atm/K.mol
T = temperature in K
First we calculate the moles of gas by putting the values according to the first condition in the above equation and we have
n = (0.921)(500) / (0.082)(473) = 11.86 moles
Now we calculate the volume of gas by using the above equation and details of the second condition as:
V = (11.86)(0.082)(293) / (30) = 9.49 L
Hence resultant volume of the gas is 9.49L.

A gas is collected at 30 Celsius and has a pressure of 200 kPa. What pressure would it exert if the temperature changed to 40 Celsius?
Answers
Answer:
[tex]206.6\ \text{kPa}[/tex]
Explanation:
[tex]P_1[/tex] = Initial pressure = 200 kPa
[tex]P_2[/tex] = Final pressure
[tex]T_1[/tex] = Initial temperature = [tex]30^{\circ}\text{C}[/tex]
[tex]T_2[/tex] = Final temperature = [tex]40^{\circ}\text{C}[/tex]
We have the relation
[tex]\dfrac{P_2}{P_1}=\dfrac{T_2}{T_1}\\\Rightarrow P_2=\dfrac{T_2}{T_1}P_1\\\Rightarrow P_2=\dfrac{40+273.15}{30+273.15}\times 200\\\Rightarrow P_2=206.6\ \text{kPa}[/tex]
The pressure that would be exerted after the temperature change is [tex]206.6\ \text{kPa}[/tex].

Why is there a bond between the ions in potassium chloride
Answers
Answer:
Explanation:
When the two atoms are in contact, potassium transfers its outer electron to chlorine which readily accepts it, resulting in both atoms achieving a state of eight outermost electrons. With this electron transfer, the ionic bond in KCl is formed.
Hope this helped!!!
Potassium has just one valence electron and Chlorine has 7 electrons, Chlorine needs just one atom to complete its octet which is provided by Potassium atom for formation of Potassium Chloride (KCl).
What is Chemical Bonding?Chemical bonding is the formation of chemical bonds present between two or more atoms or molecules which give rise to new compound. Bond is formed from electrostatic force present between oppositely charged ions like in ionic bonds or by sharing of electrons like in covalent bonds.
There are two types of Chemical Bonding:
1. Ionic Bonding
It is formed between opposite charged particles like Anion (negatively charged) and Cation (Positively charged) by the strong force of attraction.
For example, KCl formed by the ionic bond formation present between Potassium and Chlorine
2.Chemical Bonding
It is formed between two atoms for completing its octet by sharing of electrons.
For example, [tex]H_2[/tex] formed by sharing the electrons to complete its electronic configuration.
Thus, Potassium has just one valence electron and Chlorine has 7 electrons, Chlorine needs just one atom to complete its octet which is provided by Potassium atom for formation of Potassium Chloride (KCl).

A full moon appears on July 1: On what date is the next full moon likely to appear in the night sky?

C August 14

Answers
A full Moon chances roughly every 29.5 days, so it may be possible the next full moon likely to appear in the night sky of Earth on July 29, hence the option B is correct.
The lunar phase during which the Moon is completely lit from Earth's viewpoint is known as the full moon.
When Earth is situated halfway between the Sun and the Moon, this happens. This indicates that the near side of the moon, which faces Earth, is fully illuminated by the sun and appears as a roughly round disc.

The reaction of perchloric acid (HClO4) with lithium hydroxide (LiOH) is described by the equation: HClO4 + LiOH → LiClO4 + H2O Suppose 100 mL of perchloric acid is neutralized by exactly 46.9 mL of 0.75 M lithium hydroxide. What is the concentration of the perchloric acid?
Answers
Answer:
[HClO₄] = 0.35 M
Explanation:
Neutralization reaction is:
HClO₄ + LiOH → LiClO₄ + H₂O
In this case, we have a titration between a weak acid and a strong base.
In chemistry it is also called an acid base equilibrium.
HClO₄ + H₂O ⇄ ClO₄⁻ + H₃O⁺ Ka
The weak acid is firstly neutralized by the strong base, in order to have a buffer solution before the equivalence point.
When we reach the equivalence point, mmoles of acid = mmoles of base and there is a formula to determine it so:
M acid . Volume of acid = M base . Volume of base
M acid . 100 mL = 0.75 M . 46.9 mL
M acid = (0.75 M . 46.9 mL) / 100 mL → 0.35 M
