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

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.

how does the ocean affect the climate of nearby mountain ranges ?
give me a good paragraph ! for extra points pls
Answer:
Prevailing winds (sea breeze) from the ocean push warm moist air against the mountain & it moves up. As the moist air rises, it begins to get cooler and cooler due to the high altitude. ... Dry Air Since the air already lost its moisture, the humidity on this side is low & plants get very little water.
Explanation:
The oceans influence climate by absorbing solar radiation and releasing heat needed to drive the atmospheric circulation, by releasing aerosols that influence cloud cover, by emitting most of the water that falls on land as rain, by absorbing carbon dioxide from the atmosphere and storing it for years t

What does the formula of an ionic compound tell you?
Answer:
The overall ionic formula for a compound must be electrically neutral, meaning it has no charge. When writing the formula for the ionic compound, the cation comes first, followed by the anion, both with numeric subscripts to indicate the number of atoms of each.

Answer: It loses kinetic energy.
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

27/13AL+? ->> 24/11NA+4/2HE
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

How do we know that caramelizing sugar is a chemical change?
It involves dissolving sugar in water.
It changes the state of sugar from a solid to a liquid.
It separates sugar fromn a sugar solution.
It changes the sugar's color.
Answer:
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Explanation:
caramel is the product of the sugar and hot water
Answer:
D It changes the sugars color
Explanation:
Because the change of color is a chemical change.
