Which of the following accurate describes the atmospheric conditions required for the formation of clouds
Answers
Answer:
To make a cloud, air needs only to be cooled to saturation and beyond. ... Usually the water vapor amounts in air are less that this amount. When this is the case, we describe the air as being unsaturated. If we add more vapor to such air, we could reach the maximum for the temperature
Explanation:
The atmospheric conditions required for the formation of clouds are , air needs only to be cooled to saturation and beyond formation of clouds and precipitation.
What is precipitation?
Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.
Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.f a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.
Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

Which set of elements below is the most similar in chemical behavior?
OH, Be, SC
O Fr, Ra, Rf
O TI, V, Cr
O Be, Ca, Ra
Answers
Answer: Be, Ca, Ra
Explanation:
Elements are distributed in groups and periods in a periodic table.
Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.
Berrylium (Be) , Calcium (Ca) and radon (Rn) are elements which belong to Group 2. They have 4, 20 and 88 electrons respectively and contain 2 valence electrons each and thus can lose two electrons to complete their octet. Thus they will show similar chemical properties.
The chemical reactivity of elements is governed by the valence electrons present in the element.

how elements are arranged in the groups of periodic table
Answers
Answer:
Explanation:
The chemical elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency.

Worksheet: Balancing Equations
Fill in the blanks with the most appropriate term:
A ________________ ________________ tells the story of a chemical reaction. ________________ are the starting substances in the reaction while ________________ are the new substances that are formed. The large numbers in front of some of the formulas are called ________________. These numbers are used to ________________ the equation because chemical reactions must obey the Law of ________________ of Matter. The number of atoms of each element on both sides of the equation must be ________________ because matter
cannot be ________________ or ________________. When balancing equations, the only numbers that can be changed are ________________; remember that ________________ must never be changed in order to balance an equation.
II. Balance the following equations:
1. Al + O2 Al2O3

A Chemical Equation tells the story of a chemical reaction. Reactants are the starting substances in the reaction while Products are the new substances that are formed. The large numbers in front of some of the formulas are called Coefficients. These numbers are used to Balance the equation because chemical reactions must obey the Law of Conservation of Matter. The number of atoms of each element on both sides of the equation must be Equal because matter cannot be Created or Destroyed. When balancing equations, the only numbers that can be changed are Coefficients; remember that Subscripts must never be changed in order to balance an equation.

Answers
Answer:
True
Explanation:
Single celled prokaryotic cells use meiosis to reproduce. Its ''TRUE''
What is a Prokaryotic cell ?A prokaryote is a single-celled organism that lacks a nucleus, and other membrane-bound organelles.
Prokaryotic cells are single-celled microorganisms known to be the earliest on earth.
Prokaryotes include Bacteria and Archaea.
The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis.
A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm.
Prokaryotes reproduce through a cell division process called binary fission.
Like mitosis in eukaryotes, this process involves copying the chromosome and separating one cell into two.
Hence, Single celled prokaryotic cells use meiosis to reproduce is a ''TRUE'' statement.

which graph above best represents the relationship between the volume and the pressure of a gas?
Answers
The graph (A) best represents the relationship between the volume and the pressure of a gas.
What is pressure?The force was applied perpendicular to an object's surface per unit area across which that force is spread is known as pressure. The relationship between pressure and volume can be understand with the aid of ideal gas law.
PV=nRT.
where, P is pressure, V is volume.
It can be seen that when temperature will kept constant then pressure will be inversely proportional to the volume. It can be shown as:
P ∝ 1/V.
Therefore, graph A represent relationship between pressure (P) and volume (V).
