what is the density of a small block of wood with a mass of 35g and a volume of 70 cm3
Help plz
Answer:
The density of the wood is 0.5 g/cm³
Explanation:
To calculate density you need to use the formula D = M/V
D = Density
M = Mass (in grams)
V = Volume (in cm³ for solids and mL for liquids)
So, just plug in your given values: D = 35 g ÷ 70 cm³ = 0.5 g/cm³
Voila, you just calculated the density of that piece of wood!

Help out please????
Answer:
B. X= Elements, Y= Compounds
Explanation:
An element is a substance that is made up of only one type of atom. The atoms of an element can combine together chemically to form a molecule but can still exist as an individual atom e.g. Hydrogen atom; H can form molecule H2. Since only one atom makes up an element, its electrons act independently.
Compounds, on the other hand, are substances that are made up of more than one type of atom chemically combined. A compound can only exist as a molecule because it always contains more than one atom bonded together. However, since more than one atom are involved in the chemical bond that holds them together, electrons are shared with other atoms. Example of a compound is H20 containing atoms of hydrogen and oxygen that are chemically combined.

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".

write a summary about the moon phases
Answer:
A lunar phase is simply the shape of the sunlit part of the Moon, as seen from Earth. Phases are so strikingly obvious that we almost take them for granted. Moreover, they can be observed easily throughout the month from the backyard or via a simple glance out the window.
The Moon's shape changes for the following reasons:
The Moon orbits Earth.
Both Earth and the Moon orbit the Sun.
The Moon's orbit is the same length as the time it spins on its axis (about 28 Earth days), which means that we see the same part of the lunar surface all month.
The Sun illuminates both Earth and the Moon.
Get to Know the Lunar Phases
There are eight phases of the Moon to track each month.
New Moon: During New Moon, the side of the Moon facing us is not illuminated by the Sun. At this time, the Moon is not up at night, but it is up during the day. We just can't see it. Solar eclipses can occur during the New Moon, depending on how the Sun, Earth, and Moon line up in their orbits.
Waxing Crescent: As the Moon waxes (grows) into its crescent phase, it begins to show up low in the sky right after sunset. Look for a silvery-looking crescent. The side facing the sunset direction will be lit up.
First Quarter: Seven days after New Moon, the Moon is in first quarter. Only half of it is visible for the first half of the evening, and then it sets.
Waxing Gibbous: After First Quarter, the Moon appears to grow into a gibbous shape. Most of it is visible, except for a dark sliver that shrinks over the next seven nights. Look for the Moon at this time during the afternoon, too.
Full Moon: During the Full Moon, the Sun lights up the entire surface of the Moon that faces Earth. It rises just as the Sun sets and disappears beneath the western horizon when the Sun rises the next morning. This is the brightest phase of the Moon and it washes out the nearby part of the sky, making it difficult to see stars and faint objects such as nebulae.
Ever hear of a Super Moon? That's a Full Moon that happens when the Moon is closest in its orbit to Earth. The press likes to make a big deal about this, but it's really a very natural thing: On occasion, the Moon's orbit brings it closer to Earth. Not every month has a Super Moon. Despite the hype about Super Moons in the media, it's difficult for the average observer to notice one, because the Moon might appear only slightly larger in the sky than normal. In fact, the well-known astronomer Neil deGrasse Tyson pointed out that the difference between a regular Full Moon and a Super Moon is analogous to the difference between a 16-inch pizza and a 16.1-inch pizza.
Lunar eclipses occur only at Full Moons because the Moon is passing directly between Earth and the Sun in its orbit. Due to other perturbations in its orbit, not every Full Moon results in an eclipse.
The other Full Moon variation that often grabs media attention is a "Blue Moon." That's the name given to the second Full Moon that occurs in the same month. These don't happen all the time, and the Moon certainly doesn't appear blue. Full Moons also have colloquial names based on folklore. It's worth reading about some of these names; they tell fascinating stories about early cultures.
Waning Gibbous: After the glorious appearance of Full Moon, the lunar shape starts to wane, meaning it gets smaller. It's visible later at night and into the early morning, and we see a steadily shrinking shape of the lunar surface that's being lit up. The side that is lit up is facing toward the Sun, in this case, the sunrise direction. During this phase, look for the Moon during the day—it should be in the sky in the morning.
Last Quarter: At Last Quarter, we see exactly half the sunlit surface of the Moon. It can be seen in the early morning and daytime sky.
Waning Crescent: The last phase of the Moon before returning to New Moon is called Waning Crescent, and it is exactly what it says: a steadily-shrinking crescent phase. We can see only a small sliver from Earth. It's visible in the early morning, and by the end of the 28-day lunar cycle, it has vanished almost entirely. That brings us back to New Moon to start the new cycle.

Explanation:
Something shorter-The different shapes of the lit portion of the Moon that can be seen from Earth are known as phases of the Moon. Each phase repeats itself every 29.5 days. The same half of the Moon always faces the Earth, because of tidal locking. So the phases will always occur over the same half of the Moon's surface.
An equimolar mixture of X (g) and Y (g) is placed inside a rigid container at constant temperature. The particle diagram above represents the changes that occur over time. Based on the particle
diagram, which of the following best predicts whether or not the system has reached equilibrium by 300 s?
a. It is not possible to determine that the system has reached equilibrium by 300 s because the stoichiometry of the reaction is not known.
b. it is not possible to determine that the system has reached equilibrium by 300 s because the amounts of X, Y, and XY have continued to change
c. The system has reached equilibrium by 300 s because the rate of formation of XY is constant
d. The system has reached equilibrium by 300 s because the rates of consumption of X and Y are equal
Answer:
B
Explanation:
t= 300s has more XY than t=200s, which means that it continues to change
*i think
The system has been predicted to be not possible to reach equilibrium as changing X and Y concentration. Thus, option B is correct.
Equilibrium has been described as the condition in the reaction mixture, when the concentration of the product and the reactant are equal.
The given reaction has been represented as:
[tex]\rm X+Y\rightarrow\;XY[/tex]
Reaction mixture at 300 sThe given reaction has been represented as, with the increase in time, there has been the consumption of the reactant and the formation of product.
The concentration has been continuously changing with time. Thus, the determination of the equilibrium has been difficult with changing X and Y concentration.
Thus, option B is correct.

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
