Low pressure is one of the defining features of a hurricane. Therefore, the correct option is option C.
Hurricanes are intense tropical storms with spiralling winds, copious amounts of rain, and storm surges. These storms can pose a variety of issues when they hit land because they often occur over warm ocean waters close to the equator. Hurricanes leave a path of destruction in their wake, wrecking everything in their path from homes and infrastructure to creating severe flooding and landslides. The unpredictable nature of hurricanes is among their most worrisome features. Although modern technology and meteorological techniques have given us improved storm tracking and prediction systems, it is still challenging to correctly anticipate a hurricane's exact route and intensity.

pls Help ASAP - Calcium reacts with oxygen to produce calcium oxide. What mass of calcium oxide is produced when 10g of calcium burns?
Please show your working out.
Answer:
Mass = 14.025 g
Explanation:
Given data:
Mass of Ca burn = 10 g
Mass of calcium oxide produced = ?
Solution:
Chemical equation:
2Ca + O₂ → 2CaO
Number of moles of Ca:
Number of moles = mass /molar mass
Number of moles = 10 g/ 40 g/mol
Number of moles = 0.25 mol
now we will compare the moles of Ca and CaO
Ca : CaO
2 : 2
0.25 : 0.25
Mass of CaO;
Mass = number of moles × molar mass
Mass = 0.25 mol × 56.1 g/mol
Mass = 14.025 g

Choose the statement below that correctly describes electrons.
a. Electrons have a positive charge and are lighter than protons
b. Electrons have a positive charge and are heavier than protons
c. Electrons have a negative charge and are heavier than protons
d. Electrons have a negative charge and are lighter than protons
Answer:
d. Electrons have a negative charge and are lighter than protons
Explanation:
The best statement that describes electrons is that electrons are negatively charged and are lighter than protons.
There are three known subatomic particles which are:
Protons which are the positively charged particles within an atom. Electrons are the negatively charged particles Neutrons do not carry any charges.The mass of the protons and neutrons are similar.
Electrons are lighter than both protons and neutrons.
Which of the following is a polar molecule?
A. A linear Carbon dioxide molecule (C02)
B. A carbon monoxide molecule (CO)
C. A calcium oxide molecule (CaO)
D. An oxygen molecule (02)
Answer:
B. A carbon monoxide molecule(CO)
Explanation:
CO is polar because oxygen is more electronegative than carbon, so it gives oxygen a partial negative charge and carbon and partial positive charge. This causes a net dipole moment. CO2 is linear with no net dipole moment because each C-O bond is equal and opposite to each other, so they equal 0, which makes them non polar.
How many formula units are in 2.58 moles of Caci.?
Answer:
1.55 x 10²⁴ formula units
Explanation:
Given parameters:
Number of moles of CaCl₂ = 2.58moles
Unknown:
Formula units in the compound = ?
Solution:
To solve this problem, we must understand that;
1 mole of a substance contains 6.02 x 10²³ formula units
2.58 moles will contain 2.58 x 6.02 x 10²³ formula units
= 1.55 x 10²⁴ formula units

What would be the molar mass of sodium?
Answer:
Explanation: 29.99g/mol
Answer:
23.0 g/mol
Explanation:
To find the molar mass of sodium or Na, look at the periodic table.
Then try to find where sodium is.
After that, then try to check the atomic mass of sodium.
The atomic mass of sodium is 23.0
So the molar mass is 23.0 g/mol
That's it. Molar mass means the same thing as atomic mass.

Which element has the largest atom (longest atomic radius) and which element has the smallest atom (shortest atomic radius)?
Answer:
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.

sound travel through water at a speed of 1500 m/s. if the frequency of a sound is 1000 Hz, what is the wavelength?
Answer:
λ = 1.5 m
Explanation:
Given data:
Speed of wave = 1500 m/s
Frequency of sound = 1000 Hz
Wavelength of sound = ?
Solution:
Speed of wave = frequency × wavelength
by putting values,
1500 m/s = 1000 Hz × λ
λ = 1500 m/s / 1000 s⁻¹ (Hz = s⁻¹ )
λ = 1.5 m
Answer: 1.5
Explanation:
Well first you do
1500/ 1000= 1.5 which mean

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, the correct option is option A.
What is atom?
Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. Most atoms are bonded together to make a molecule. Molecules combine to form compounds.
Therefore, the correct option is option A.

Answer:
113
Explanation:
We are given that the atom of cadmium has 66 neutrons:
Number of neutrons in Cd = 66
Now;
Mass number = ?
The mass number of an element is the sum of the number of protons and number of neutrons
Mass number = number of protons + number of neutrons
By the position of cadmium, it has an atomic number of 47 and this is the number of protons
Mass number = 47 + 66 = 113
