name two units for density? I need help!!!!
Answer:
Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth ’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in MKS or SI units). For example, the density of air is 1.2 kilograms per cubic metre.

You are an employee at "cash for gold" and a customer comes in looking to exchange gold for money. They claim to have 3.47 gram nugget of fold. How many particles (atoms) of gold are in one nugget? With work shown
Answer:
The number of atoms in 3.47 gram nugget of gold is approximately 1.0606 × 10²² atoms
Explanation:
The given mass of gold = 3.47 grams
The molar mass of gold = 196.96657 g/mol
The number of moles of gold in 3.47 grams of gold = 3.47 grams/(196.96657 g/mol)
The number of moles of gold in 3.47 gram nugget of gold = 0.01762 moles
The number of atoms in one mole of gold = 6.02 × 10²³ atoms
The number of atoms in 0.01762 moles of gold = 6.02 × 10²³ atoms/mole × 0.01762 moles
The number of atoms in 0.01762 moles of gold ≈ 1.0606 × 10²² atoms
∴ The number of atoms in 3.47 gram nugget of gold ≈ 1.0606 × 10²² atoms.

If Maria winks exactly 5 times every minute while she is awake and she sleeps exactly 8 hours a day, how many times does Maria wink in a day? winks/day.
Answer:4,800
Explanation:
5 winks a minute, 60 minutes in an hour.
300 winks an hour, 16 hours a day.
4,800.
Answer:
The answer is 4,800 winks per day.
Explanation: There are 24 hours in a day, 24 minus the 8 hours shes asleep is 16. There are 60 minutes in an hour. 5 x 60 is 300. 300 winks an hour multiplied by the 16 hours she's awake is 4,800.

Which of these elements has an electron configuration of [Kr]5s2?
barium
calcium
rubidium
strontium
Strontium has an electron configuration of [Kr]5s²
Further explanationIn an atom there are levels of energy in the shell and sub shell
This energy level is expressed in the form of electron configurations.
Writing electron configurations starts from the lowest to the highest sub-shell energy level. There are 4 sub-shells in the shell of an atom, namely s, p, d and f. The maximum number of electrons for each sub shell is
s: 2 electrons
p: 6 electrons
d: 10 electrons and
f: 14 electrons
From an electron configuration of [Kr]5s² can be concluded :
element is in period 5 (5 = shell)element is group 2(valence electron =2 and block s) has atomic number 38 (Kr = 36 + 2(valence elektron from 5s²)If we look at the periodic system, the elements that meet the requirements in question are Strontium (Sr)
Answer:
D) strontium

compare and contrast gymnosperms and angiosperms
(JSYK: this is technically biology)
Anyways, a gymnosperm is a plant (usually a tree) that has unprotected seeds, this means it bears no fruits and can include (but are not limited to) connifers, cycads, and the ginko. Angiosperms produce flowers to help fertilization and have protected seeds. They are also likely to produce fruits or vegetables.

A student determines the density of an element to be 2.73 g/cm 3 . If the accepted value is 2.70 grams per cm 3 , what is the student's percent error? Identify the element. What is the boiling of this element in Celsius degree
Answer:
Explanation:
percentage error = error x 100 / correct value
= (2.73 - 2.70) x100 / 2.70
= 1.11 %
The element is Aluminium whose density is 2.702 grams / cc
Boiling point of Aluminium = 2519⁰C .

Wich statement best describes the progress of science
Answer:
Scientific ideas are changed when better ones are found.
Explanation:
This chart shows characteristics of three different types of atoms.
A 3-column table with one row titled valence electrons in three types of atoms. The first column labeled Atom X has entry 6 valence electrons. The second column labeled Atom Y has entry 2 valence electrons. The third column labeled Atom Z has entry 8 valence electrons.
Which statement is best supported by the information in the chart?
Atom X will donate electrons to Atom Y.
Atom X will accept electrons from Atom Y.
Atom Y will accept electrons from Atom Z.
Atom Z will donate electrons to Atom X.
Atom X will accept electrons from Atom Y.
Answer:
B) Atom X will accept electrons from Atom Y.
Explanation:
because X has 6 electrons and Y has 2 it would make sense for Y to give to X
A hiker tries to prepare a hard-boiled egg on the high slopes of Mount Everest. The base camp is located 5,300 meters above sea level. The hiker observes that the water begins to boil at 82⁰C, much lower than the 100⁰C needed to cook the raw egg. He hopes that just leaving the egg in the boiling water longer will let the egg cook. Will he have hard-boiled eggs for breakfast?
Answer:
He will not have hard-boiled eggs for breakfast
Explanation:
The given parameters are;
The elevation at which the base camp of the hiker is located = 5,300 meters
The boiling point of water at the elevation of the base camp = 82°C
The temperature required to cook the raw egg = 100°C
Therefore, we have;
The temperature of the boiling water at the given elevation of the base camp 82°C < The temperature required to cook the raw egg 100°C
Therefore, the eggs will not be hard boiled.
The hiker won't have hard-boiled eggs for breakfast as a result of the
boiling point of water being less than 100⁰C.
The boiling point decreases with an increase in altitude. The hiker was at
5,300 meters above sea level which made the boiling point of water to be
decreased to 82⁰C.
Since the water isn't able to achieve the boiling point of 100⁰C, then the raw
egg won't be hard boiled for breakfast.
