Answer:
Yes
Explanation:
It does because of the fact that plants need water to live and the grow. Water helps the plant grow, and certain plants would need less or more water based on their roots, leaves, and tempurature tolerancy.
Answer: Yes,
Roots need both water and oxygen, and when surrounded by water, they cannot take up oxygen. Plants may slow in growth after a flush of new growth or a heavy flowering. During these periods and while it is dormant, a plant will need less water.

How do intermolecular forces among entities in an ideal gas compare to those among entities in a real gas
Answer:
An ideal gas has identical particles of zero volume, with no intermolecular forces between them. The atoms or molecules in an ideal gas move at the same speed. Almost all gases obey the gas laws within a limited range of pressures and temperatures.

How do we calculate moles?The mole (symbol mol) is the SI base unit of material quantity. The amount of substance in an object or sample is a measure of how many elementary entities of a certain substance are present.
Given chemical reaction is:
[tex]2CO + O_2[/tex] → [tex]2 CO_2[/tex]
From the stoichiometry of the reaction, it is clear that 2 moles of carbon dioxide are produced.
Actual moles will be calculated by using the enthalpy and energy value as:
Actual moles of [tex]CO_2[/tex] = 275kJ × ([tex]\frac{2 mol}{566 kJ}[/tex]) = 0.97 moles.
Grams of carbon dioxide = moles X molar mass of carbon dioxide.
Grams of carbon dioxide = 0.97 X 44.01 g/mol
Grams of carbon dioxide = 42.6897 g

if 500 g of iron absorbs 22000 cal of heat, what will be the change in temperature? (specific heat of iron = 0.11 cal/gC)
Answer:
400°C
Explanation:
22,000 cal / (0.11 cal/g°C x 500 g) = 400°C
Answer:
400 C degree change
Explanation:
22 000 cal = 500 g * (C) * .11 cal / g-C
C = 22 000 / (500*.11) = 400 C degree change

What is the approximate tangential speed of an object orbiting earth with a radius of 1.8 × 108 m and a period of 2.2 × 104 s? 7.7 × 10–4 m/s 5.1 × 104 m/s 7.7 × 104 m/s 5.1 × 105 m/s
This question involves the concepts of time period and tangential speed.
The tangential speed of the object is "5.1 x 10⁴ m/s".
What is the time period?The following formula gives the time period of the object:
[tex]T=\frac{2\pi}{\omega}\\\\[/tex]
[tex]\omega = \frac{2\pi}{T}[/tex]
where,
[tex]\omega[/tex] = angular speed = ?T = time period = 2.2 x 10⁴ sTherefore,
[tex]\omega=\frac{2\pi}{2.2\ x\ 10^4\ s}\\\\\omega=2.86\ x\ 10^{-4}\ rad/s[/tex]
Now, the tangential speed can be given by the following formula:
[tex]v=r\omega[/tex]
where,
r = radius = 1.8 x 10⁸ mv = tangential speed = ?Therefore,
[tex]v=(1.8\ x\ 10^8\ m)(2.86\ x\ 10^{-4}\ rad/s)[/tex]
v = 5.1 x 10⁴ m/s

how do atoms show both unity and diversity
Answer: As one atomic dipole nears another atom it will affect the electron density distribution, so for example if the slightly positive end of the atom is located next to another atom, it will attract the electron(s) in the other atom. A covalent bond happens when atoms share an electron between them. The other kind of bond is called ionic, and it happens when one atom gives an electron to another atom. These bonds are held together with electric forces. Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are different.
Answer:

The weak base ionization
constant (Kb) for HCO3 is
equal to:
Weak bases are alkaline solution that does not get completely dissociated. The dissociation constant will be the ratio of the concentration of the products to the reactants.
What is a weak base ionization constant?The weak base ionization constant is the equilibrium constant that is given as the division of the products of the ionization to the concentration of the reactants.
The reaction for HCO₃ is given as:

The statement about the number of moles of acid and base being the same is true in the neutralisation reaction between the acid HCl and base NaOH.
What is neutralisation reaction?A neutralisation reaction is the type of chemical reaction whereby an acid reacts with a base to form salt and water.
HCl + NaOH --------> NaCl + H2O
In the neutralisation reaction, between the acid HCl and base NaOH above, the balanced chemical equation showed that the initial number of moles of acid is equal to the final amount of the number of moles of known base which is NaOH.
Therefore, the statement about the number of moles of acid and base being the same is possible in the neutralisation reaction between the acid HCl and base NaOH.

Answer:
The number of protons is 30. Substitute the known values, where N represents the number of neutrons. Let's rewrite the equation as 30+N=65 30 + N = 65 .
Answer:
35 neutrons
Step by step explanation:
Atomic mass of Zinc: 65 amu (atomic mass units)
Number of protons in Zinc: 30
Number of neutrons in Zinc: Atomic mass of Zinc - Number of protons in Zinc = 65-30 = 35 neutrons.

What are radioactive decay series?Series (or family) of natural radioactive decay is the set of elements with unstable nuclei, which follow an orderly sequence of spontaneous decay, that is, they emit alpha and beta particles, until a stable lead nucleus is created.
In this case, natural radioactive decay occurs when the nucleus of the atom of some chemical element is unstable and then it "breaks", releasing electromagnetic radiation and disintegrating.
