Matter that is made up of only one kind of Atom
Answer:
elements
Matter that has only one kind of atom is called an element. Gold, copper, oxygen, and mercury are examples of elements. Most matter is made up of two or more different kinds of atoms that are chemically combined. This kind of matter is called a compound.
Explanation:
Answer:
Element
Explanation:
This is the answer because:
1) All matter is made up of substances called elements.
2) Matter that iis made up of only one kind of Atom is called an Element.

Which description properly describes the plant structures involved in photosynthesis?
Stomata take in water, sunlight, and carbon dioxide and release oxygen.
Phloem transports water, stomata take in carbon dioxide, and chlorophyll absorbs sunlight.
Xylem takes in water, sunlight, and carbon dioxide and releases oxygen.
Stomata take in carbon dioxide and release oxygen.
Answer:
Stomata take in water, sunlight, and carbon dioxide and release oxygen.
Explanation:
Photosynthesis collects and absorbs sunlight and converts the sunlight into sugars (glycose), then the plant stores the sugar and uses it.

Answer:
hhhsstyi chick to yay to today do y'all
Answer:
¹₀n
Explanation:
The given expression is:
²⁷₁₃Al + ₐᵇT → ²⁴₁₁Na + ⁴₂He
This expression is typical of nuclear reactions. To balance this expression we must conserved the mass number and the atomic number.
The mass number is the superscripts and the atomic number is the subscript;
Now;
conserving mass number:
27 + b = 24 + 4
27 + b = 28
b = 28 - 27 = 1
conserving the atomic number;
13 + a = 11 + 2
13 + a = 13
a = 0
So;
The particle T is a neutron ¹₀n

Which of the following is not true about one mole?
the mass of 1 mole of carbon atoms = the mass of
1 mole of boron atoms
one mole contains 6.02 x 1023 particles
the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron
12 g of carbon equals one mole of carbon atoms
Answer:
A
Explanation:

The number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron is not true about one mole.
What element of one mole is false?It is untrue to say that one mole of fluorine gas weighs more than one mole of oxygen gas. Fluorine gas has a molar mass of 38 grams per mole, whereas oxygen gas has a molar mass of 32 grams per mole, based on their relative molar masses.
A mole of a substance is equal to 6.022 × 10²³ of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is referred to as "Avogadro's number" or "Avogadro's constant."
Since boron has a different molar mass than carbon, the statement that there are the same number of atoms in each mole is untrue.
The ratio of the substance's mass to its molar mass is used to express the number of moles of an element.
Moles = Mass/Molar mass
Given that the molar masses of carbon and boron differ, the statement that the number of atoms in a mole of carbon is equal to the number of atoms in a mole of boron is false.
Therefore, the correct answer is option c) the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron.
The complete question is:
Which of the following is not true about one mole?
a) the mass of 1 mole of carbon atoms = the mass of
b) 1 mole of boron atoms
one mole contains 6.02 x 1023 particles
c) the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron
d) 12 g of carbon equals one mole of carbon atoms

what is the mass of the atom
Answer:
19
Explanation:
The mass of an atom is given by its mass number. This is because the mass of an atom is concentrated at the nucleus.
Mass number = number of protons + number of neutrons
Protons and neutrons are the most massive particles in any atom.
Protons are the positively charged particles in an atom
Neutrons are uncharged particles.
So, the mass number of this atom is:
Mass number = 9 + 10 = 19

what mass of carbon dioxide is produced from combustion of 100.0 grams of propane (C^3H^8)
Answer:
Mass of CO₂ produced = 299.64 g
Explanation:
Given data:
Mass of CO₂ produced = ?
Mass of propane (C₃H₈) = 100.0 g
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Number of moles of propane:
Number of moles = mass/molar mass
Number of moles = 100.0 g/ 44.1 g/mol
Number of moles = 2.27 mol
Now we will compare the moles of propane and carbon dioxide.
C₃H₈ : CO₂
1 : 3
2.27 : 3/1×2.27 = 6.81 mol
Mass of CO₂:
Mass = number of moles × molar mass
Mass = 6.81 mol × 44 g/mol
Mass = 299.64 g

The density of mercury is 13.6 g/mL. What is the mass of 3,426 mL of mercury?
Answer:
m = 46593.6 g
Explanation:
Given data:
Mass of mercury = ?
Volume of mercury = 3426 mL
Density of mercury = 13.6 g/mL
Solution:
Formula:
d = m/v
d = density
m = mass
v = volume
by putting values,
13.6 g/mL = m/ 3426 mL
m = 13.6 g/mL × 3426 mL
m = 46593.6 g
