Where does the energy of a hurricane come from? (1 point)
O the Sun
O strong winds
O Earth's spin
O Earth's moon
Answer:
strong winds come from the energy of a hurricane
The energy of a hurricane come from strong wind. The Taino Native American term hurricane, which translates to "bad spirit of the wind," is where the word hurricane originates.
What is hurricane ?A tropical storm that has sustained winds of 74 mph or greater is referred regarded as a hurricane. A storm's eye typically measures 20 to 30 miles in width and can reach distances of 400 miles. Storms can be dangerous because of their torrential downpours, strong gusts, and storm surges.
When warm, humid air begins to rise over water, hurricanes emerge. Cooler air replaces the rising air. Large clouds and thunderstorms continue to grow as a result of this process. Thanks to the earth's Coriolis Effect, these thunderstorms are still expanding and starting to rotate.
Thus, option B is correct.

Answer:
129 units cubed
Explanation:
There are ten spaces between 120 and 130, so we can infer that each line represents a change in volume of 1 unit. The volume of the substance in the graduated cylinder looks like it's 1 under 130, so its volume is 129 units.

Explanation:
Aqueous hydrobromic acid HBr will react with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O. Suppose 3.24 g of hydrobromic acid is mixed with 2.3 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.
Answer:
7.20 X 10^-2 gm
Explanation:
Aqueous hydrobromic acid HBr will react with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O. Suppose 3.24 g of hydrobromic acid is mixed with 2.3 g of sodium hydroxide. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.
HBr(aq) + NaOH (S)-----------> NaBr (aq) + H20
mol wt of HBr = 1 + 79.9 = 80.9
3,24 gm of HBr = 3.24/80.9 = 0.00400moles = 4.00 X 10^-3 moles
mol wt of NaOH = 23.0 + 16.0 +1.01 = 40.0 gm
2.3 gm = 2.3/40.0 = 0.058 moles =5.8 X 10^-2
the reaction of HBr and NaOH is 1:1.
there are not enough moles of HBr to neutralize all of the NaOH. so
only 4.00X10 ^-3 moles of H2O can be produced
mol weight of H2O is (2 X 1.01) + 16.0 = 18.0
The maximum mass of H2O that can be produced is
18.0 X 4.00X10^-3 = 72.0/1000 =7.20 X 10^-2 gm

Perform the following operations giving the proper number as a benefit get figures in the answer.
Help
Answer:
Use calculator but first group them one by one and open the bracket by solving them accordingly
The number we get by this operation is 0.016. This number can be taken based on the rules for significant figures.
What is significant figures?The number of significant figures is the number of digits that are known with certainty plus the last one having some uncertainty. All non zero values are significant and zero preceding first non zero digit is not significant .
For example in 65000, there are only two significant figures. Similarly in 0.08 only one significant digit is present. Now when we multiply two decimal numbers, the result can only have as many decimal places as there are in the value with fewest decimal places.
First, multiply the numbers inside the bracket. As per the above rule, the result should contain only two decimal places.
(0.08 ×200×0.004) = 0.06
Multiply by 65000 - 0.06×65000 = 3900
Now divide it by the multiplication product (800× 300), 240000 we get as follows:
3900÷240000 = 0.016
Hence the result of this operation is 0.016.

When table salt forms, which action occurs between the reacting elements? (1 point)
O Chlorine donates an electron to sodium.
Sodium shares an electron with chlorine. O Sodium donates an electron to chlorine.
O Chlorine exchanges an electron with sodium.
Answer: C: Sodium donates an electron to chlorine.
Explanation:
Sodium wants to lose an electron and chlorine wants to gain an electron to become stable. This is because of their place in the periodic table, sodium being on the very left edge and chlorine on the very right (noble gasses dont count as they are stable to begin with)
Therefore sodium will donate to chlorine so they both become stable with an ionic bond. (another way to tell its ionic is the very large difference in electronegativity)
When table salt forms, sodium donates an electron to chlorine resulting in the formation of bond which is formed when the electronic configurations become stable.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
