What color offspring did you get when you crossed a brown "BB" rabbit to a white "bb" rabbit?
Answer:
Bb rabbit
Explanation:
In an ecosystem , when a brown "BB" rabbit is crossed to a white "bb" rabbit offsprings with genotype Bb are produced.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Two balloons are given an electrostatic charge by rubbing them with a wool cloth. Which observation provides evidence of the force that the balloons exert on each other over a distance because of their charge?
Answer:
C. Moving Balloon 1 can make Balloon 2 move without the balloons touching.
Explanation:
When two balloons are rubbed with a wool cloth, they get electrostatic charge and both become negatively charged.
If both balloons will be place close together, balloon 1 will push the balloon 2 far from itself without touching it as they both are negatively charged and things with same charges repel each other.
Hence, the correct answer is "C. Moving Balloon 1 can make Balloon 2 move without the balloons touching."

In naming the compound PCl5, the prefix used with the second element is ____________________.
Answer:
[tex]\boxed {\boxed {\sf Hepta}}[/tex]
Explanation:
We are given the formula:
[tex]PCl_5[/tex]
This is a molecular formula, because it contains nonmetals.
1. Name the first element
The first element is phosphorous (P). Since this is the first element and there is only one, we don't need a prefix.
Phosphorous2. Second element
The second element is chlorine (Cl). It has a subscript of 5, so we must add the prefix of hepta-.
Phosphorous heptachlorineAdd the ending of -ide.
Phosphorous heptachlorideThe prefix used for the second element is hepta. The compound name is phosphorous heptachloride.
Do you think thermal expansion affects all states of matter or just the solid? Explain your thinking.
Answer:
All three states of matter (solid, liquid and gas) expand when heated. The atoms themselves do not expand, but the volume they take up does.
When a solid is heated, its atoms vibrate faster about their fixed points. The relative increase in the size of solids when heated is therefore small. Metal railway tracks have small gaps so that when the sun heats them, the tracks expand into these gaps and don’t buckle.
Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids. This is the principle behind liquid-in-glass thermometers. An increase in temperature results in the expansion of the liquid which means it rises up the glass.
Molecules within gases are further apart and weakly attracted to each other. Heat causes the molecules to move faster, (heat energy is converted to kinetic energy) which means that the volume of a gas increases more than the volume of a solid or liquid.
However, gases that are contained in a fixed volume cannot expand - and so increases in temperature result in increases in pressure.:

What is periodic table ?In periodic table there is an arrangement of chemical element which are arranging in row and column called as group and period. This arrangement of an chemical element is according to their atomic number.
It is known as the periodic table because of the way the elements are arranged. It is widely used in chemistry, physics, and other sciences.
The elements are listed on the periodic table in order from lightest, or smallest, to heaviest, or biggest. The number in the table denotes this number of protons. The elements with 8 electrons in an outer 'd' subshell belong to Group 8.

volume of 5.2 X 10^26 molecules of CH4
Answer:
19348.84 L
Explanation:
At STP, we know that;
6.02 × 10^(23) molecules = 22.4 L
Therefore, 5.2 × 10^(26) molecules = 5.2 × 10^(26) × 22.4/(6.02 × 10^(23)) = 19348.84 L
Thus, volume of CH4 with 5.2 X 10^26 molecules is 19348.84 L

Explain what the periodic table is and how it's organized
Answer:
The periodic table is a set of elements organized by their atomic number, from lowest (hydrogen 1) to highest (oganesson 118). That number is the amount of protons in the nucleus of an atom of the element. The table is split into three groups of elements (metals, nonmetals and metalloids). As you go down the table the elements are more reactive.

A compound has the empirical formula C2H40, and its formula mass is 88
g. What is the subscript for oxygen in the molecular formula? *
Answer:
2
Explanation:
The molecular formula can be derived from the empirical formula of a compound and the molecular mass as follows:
(C2H4O)n = 88g/mol
Where;
C = 12, H = 1, O = 16
{12(2) + 1(4) + 16}n = 88g/mol
{24 + 4 + 16}n = 88
(44)n = 88
44n = 88
Divide both sides by 44
n = 88/44
n = 2
The molecular formula is: (C2H4O)n
= (C2H4O)2
= C4H8O2
According to the question asked, oxygen has a subscript of 2 in the molecular formula.
