If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many gits are equal to 5gews?
Answer:
500 hits
Explanation:
If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many hits are equal to 5 geese?
Solution:
Given that:
20 hits = 1 web, 1 futz = 2 geese; 10 webs = 1 futz
10 webs = 1 futz; hence:
1 web = 1 web * 1 futz / 10 webs = 0.1 futz
1 web = 0.1 futz
1 futz = 2 geese; hence:
0.1 futz = 0.1 futz * 2 geese / 1 futz
0.1 futz = 0.2 geese
Therefore, 1 web = 0.1 futz = 0.2 geese
1 web = 0.2 geese
This means that 20 hits = 1 web = 0.2 geese
20 hits = 0.2 geese
5 geese = 5 geese * 20 hits / 0.2 geese
5 geese = 500 hits

Q+ ( poistive ion ) is an ion of element Q.
What has the highest value in the ion?
The proton number has the highest value in the ion
In an atomic element Q, the mass number is the number of the proton and the neutron, the electron encircles around the nucleus of the atomic element.
Recall that:
The electron is usually negatively charged;The neutron is a neutralThe proton is usually positively charged.∴
The atomic element Q+ has a positively charged ion, Thus, the proton number in the mass of the atomic element Q, therefore, has the highest value in the ion.

How do the different processes of a rock cycle change a rock? Which processes will form an igneous, sedimentary, and metamorphic rock
Which is an example of physical weathering?
limestone in rock dissolving when acid rain flows across it
bits of rock rusting when exposed to oxygen and water
wind blowing off bits of a rock over time
oxidation of certain metals in rock
answer: bits of rock rusting when exposed to oxygen and water
Explanation: i think because when it rains the water is left and freezes and night making the rock expand or start to Rust

Does a rumor spread faster in a gym where all of
the students can move around freely, or in a classroom where students are
confined to desks? Develop an analogy for the difference in conductivity
between metals and ionic solids.
A rumor spread faster in a classroom where students are confined to desks than in a gym where all of the students can move around freely.
The same applies to conductivity between metals and ionic solids because metals have more close particles.
What is conductivity?Conductivity is the process by which a material is able to transfer electric charge or heat from one point to another without the actual movement of the particles of the substance.
The conductivity of substances varies from one substance to another.
The conductivity of solids is greater than the conductivity of that of other substances.
The conductivity of substances increases with a decrease in the distance between the particles of the substance.
Thus solids that have the closest particles have the highest conductivity.
Liquids have medium conductivity.
Gases have the least conductivity because they have the most spaced-out particles.

what is photosysthies
Answer:
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
Explanation:
Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Explanation:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants. Plants are also crucial to human life because we rely on them as a source of food for ourselves and for the animals that we eat.

Limonene is an oil from oranges and lemons. Click on all the carbon
atoms its structures that have a trigonal planar molecular geometry.
Answer:
See explanation
Explanation:
Limonene is an oil from oranges and lemons. Its structure has been shown in the image attached to this answer.
There are two different groups of carbon atoms in limonene. One group of carbon atoms are sp2 hybridized while the other group are sp3 hybridized. The group of carbon atoms that are sp2 hybridized have a trigonal planar geometry and have been accurately labeled in the image attached while the carbon atoms that are sp3 hybridized were also labelled and have a tetrahedral geometry.
Hence in limonene, there are trigonal planar and tetrahedral carbon atoms.

a. Identify the type of reaction shown:
Li + CaCl2 ---> LiCl + Ca
Answer:
single-replacement reactions
Explanation:
A single-replacement reaction is defined as a chemical reaction in which one strong element replace the other weak element.
The given chemical equation Li + CaCl2 ---> LiCl + Ca is an example of single-replacement reactions in which Lithium (Li) is stronger than Calcium (Ca) and replaces calcium to form bond with Chloride.
Hence, the correct answer is "single-replacement reactions".
A student did an investigation to determine the effect the amount of air would have on plant growth. She planted identical
plants in 4 separate closed containers with different volumes of air. She measured the height of the plants after they had
grown for 3 weeks.
What is the dependent (responding) variable in her investigation?
Answer:
Explanation:
The responding variable always is measured against the variable that you have control over.
In this case, you have control over the volume of air.
The responding variable is the amount the plant has grown. This would be a good long term experiment to try for a science fair or just because you might be interested. It's a good simple idea.
