paragraph about earth getting hotter /will give brainliest
Answer:
Scientists have measured global temperatures for over a hundred years and see that the Earth is getting hotter. The trend can be best visualized by comparing each year’s average temperature with the long-term average. This figure shows observations of the world’s annual average temperature made by the National Oceanic and Atmospheric Administration (NOAA). It compares each year’s temperature to the average over the entire century. Blue bars are years that were cooler than average and red bars are years that were warmer than average. In recent decades, the years have always been hotter. If there were no long-term temperature trend, you would expect a mix of red and blue bars throughout the record. That’s not what we see.
Extra greenhouse gases in our atmosphere are the main reason that Earth is getting warmer. Greenhouse gases, such as carbon dioxide (CO2) and methane, trap the Sun's heat in Earth's atmosphere.
Marine heat waves have already doubled in number since 1980 and are expected to become more intense as temperatures rise

Answer:
Sedimentary rocks
Explanation:
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation.
The process of deep sediment burial causes sediment to get compressed and cemented resulting in sedimentary rock. Here the recorded observations of the scientist is about sedimentary rocks. The correct option is B.
What are sedimentary rocks?The rocks which are formed by the deposition and subsequent cementation of the material at the surface of the earth within the bodies of water can be defined as the sedimentary rocks. They are of three types. They are organic, clastic and chemical sedimentary rocks.
Sedimentary rocks are generated by the accumulation of the existing rocks or fragments of extinct organisms on the earth surface. They are formed from the pre-existing rocks or pieces of once living organisms.
The common sedimentary rocks are sandstone, limestone and shale. Biologic sedimentary rocks are formed when large number of living things die. Chert is an example for this.
Thus the correct option is B.

The unit for molar mass is
Which halogen has the highest boiling point.
a.) f2
b.) cl2
c.)br2
d.) i2
Answer:
D
Explanation:
Recall that boiling points increase with stronger intermolecular forces.
Because halogens are diatomic molecules, they are nonpolar and lack the ability to form hydrogen bonds. Therefore, the only IMF they possess are London dispersion forces.
Recall that London dispersion forces increase with increasing polarizability, which is higher in larger molecules due to the increased number of electrons.
The largest halogen is iodine (I₂). Therefore, it will have the strongest IMF and hence the highest boiling point.
Predict the vapor pressure of a solution of 261 ml of glycerol, in 379 ml of water, at the normal boiling point of water
The vapour pressure of the solution of glycerol is 106.4 torr.
What is vapour pressure?The vapour pressure is given as the pressure extered by the individual sample in a solution. According to Roult’s law, the vapour pressure of mixture is given as:
[tex]\rm Vapor\;pressure\;of\;solution=moles\;of\;solute\;\times\;vapour\;pressure\;of\;pure\;solvent[/tex]
The density of glycerol is 1.25 g/mL. The mass of glycerol in 261 mL will be:
[tex]\rm Density=\dfrac{mass}{volume}\\\\1.25\;g/mL=\dfrac{mass}{261\;mL}\\\\Mass =326.25\;g[/tex]
The moles of glycerol are given as:
[tex]\rm Moles=\dfrac{mass}{molar\;mass}\\\\Moles=\dfrac{326.25}{92.09\;g/mol}\\\\Moles=3.54\;moles[/tex]
The density of water is 1, thus the mass of 379 mL water is 379 grams. The moles of solvent are:
[tex]\rm Moles=\dfrac{379}{18\;g/mol}\\\\Moles=21.05\;moles[/tex]
The mole fraction of solute is given as:
[tex]\rm Mole \;fraction=\dfrac{moles\;of\;solute}{moles\;of\;solute\;+\;moles\;of\;solvent}\\\\Mole\;fraction=\dfrac{3.54}{3.54+21.05}\\\\Mole\;fraction=0.14[/tex]
The mole fraction of solute is 0.14. The vapour pressure of pure water at boiling point is equivalent to the atmospheric pressure i.e. 760 torr.
Substituting the values in Roult’s law, the vapour pressure of solution is given as:
[tex]\rm Vapor\;pressure=0.14\;\times\;760\;torr\\Vapor\;pressure=106.4\;torr[/tex]
The vapour pressure of the solution of glycerol is 106.4 torr.

if 0.01 mol neon gas at a particular temperature and pressure occupies a volume of 0.225 L. what volume would 0.05 mol neon gas occupy under the same conditions
If 0.01 mol of neon gas at a particular temperature and pressure occupies a volume of 0.225 L, then 0.05 mol of neon gas would occupy a volume of 1.125 L under the same conditions.
Given:
Number of moles of neon gas (n₁) = 0.01 mol
Volume of neon gas (V₁) = 0.225 L
We are required to find the volume of neon gas (V₂) when the number of moles (n₂) is 0.05 mol under the same conditions.
The relationship between the number of moles, volume, and pressure of a gas is given by the ideal gas law: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.
Since the temperature and pressure are the same in this case, we can rearrange the ideal gas law equation to solve for the volume:
V = (n₁ * V₁) / n₂
Substituting the given values into the equation:
V₂ = (0.01 mol * 0.225 L) / 0.05 mol
V₂ = 0.00225 L / 0.05 mol
V₂ = 0.045 L/mol
Therefore, 0.05 mol of neon gas would occupy a volume of 1.125 L under the same conditions.
