In your opinion, would there be a difference in your wieght in Baguio and in Manila ?
Why or Why not
Answer:
My wife and I just visited the City of Baguio for a week. We stayed at the Hotel Supreme Convention, which was very nice. We ate dinner at some really nice places: Mario's (expensive), Don Henrico's (mid), and Good Taste (cheap). We found a nice bar called the Old Bohemian for good live music. We ventured out toward Camp John Hay a couple of times for shopping(the commissary is a tourist trap with retail prices). We also did some street shopping.

Answer:
Why would there be a difference in weight if you live in a different place?Explanation:
[tex]--------------------------------------------[/tex]
If you lived in Manila or Baguio, how would your weight change? It would probably depend on what they are eating, how long they exercise, but not living in a different place, right? This is mind - boggling and i don't know what you mean or if you're asking a different question.

Question 14 Multiple Choice Worth 2 points) If we have less power, we most likely have
A. the same amount of work being done over a shorter period of time
B.more work done over a shorter period of time
C. more work done over the same amount of time
D.the same amount of work being done over a longer period of time
Answer:
D.

makes most sense for this question. when you're using the same amount of power over a longer period–you're bound to have less of it over time.
Why is it important to use scientific notation when talking about our solar system
and galaxies?
Answer:
The main purpose for converting numbers into scientific notation is to make calculations with surpisingly large or small numbers less complicated. Since zeros are not used to place the decimal point, all of the digits in a number in scientific notation are meaningful and easier to read. Hope this helps!

How many grams of F2 are in 3.45 x 1022 molecules of F2?
Answer:
Mass = 2.16 g
Explanation:
Given data:
Number of molecules of F₂ = 3.45 × 10²²
Mass in gram = ?
Solution:
Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules
3.45 × 10²² molecules ×1 mol / 6.022 × 10²³ molecules
0.57× 10⁻¹ mol
0.057 mol
Mass in gram :
Mass = number of moles × molar mass
Mass = 0.057 mol × 37.9 g/mol
Mass = 2.16 g
A 4.03 g sample of nitrogen gas has a volume of 921 milliliters at a pressure of 3.19 atm. The temperature of the N2 gas sample is:_____.
Answer:
249 K
Explanation:
Step 1: Given data
Mass of nitrogen (m): 4.03 gVolume of the gas (V): 921 mL = 0.921 LPressure of the gas (P): 3.19 atmStep 2: Calculate the moles corresponding to 4.03 g of nitrogen
The molar mass of N₂ is 28.01 g/mol.
4.03 g × 1 mol/28.01 g = 0.144 mol
Step 3: Calculate the temperature of the gas sample
We will use the ideal gas equation.
P × V = n × R × T
T = P × V / n × R
T = 3.19 atm × 0.921 L / 0.144 mol × 0.0821 atm.L/mol.K
T = 249 K

shivering when your cold generate heat to warm your body which characteristic of life does the refer to
Answer:
Your body needs to keep a core temperature of about 98.6°F (36.9°C). To prevent hypothermia and other consequences of a chilled core, your brain monitors temperature very closely.
Explanation:
which formula represents a nonpolar molecule containing polar covelant bond
Answer: H2O and NH3 are polar molecules. H2 is a nonpolar molecule but the H-H bond is also nonpolar.
Therefore, the best choice is CCl4. Although the C-Cl bond is polar due to electronegativity differences, the molecule itself is nonpolar because the net dipole moments cancel out, given its tetrahedral molecular structure.

What is the mass of 1.00 mol of oxygen (O2)?
Answer:
Mass = 32 g
Explanation:
Given data:
Number of moles of oxygen = 1.0 mol
Mass of oxygen = ?
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of oxygen (O₂) is 32 g/mol
by putting values,
1.0 mol = mass/ 32 g/mol
Mass = 1.0 mol ×32 g/mol
Mass = 32 g

How are ionic compounds named?
Answer:
Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions. For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion.

More water is evaporated by oceans than is returned to them by precipitation. What is the source of the balance of the water?
Answer:
Following are the solution to this question:
Explanation:
Evaporate involves pushing to liquid from either a liquid phase. It's used passively, like in the overnight loss of moisture, and aggressively, as in the substrate loss of moisture by the light. The vaporized water is coming from the sea, but only 77% of the precipitation occurs and over the ocean as well as the remaining rain falls over land. Groundwater and rainwater are the primary sources of water.
The chemical formula for magnesium oxide is MgO. A chemist determined by measurements that 0.030 moles of magnesium oxide participate in a chemical reaction. Calculate the mass of magnesium oxide that participates.
Answer:
1.209g of MgO participates
Explanation:
In this problem, we have 0.030 moles of MgO that participates in a particular reaction.
And we are asked to solve for the mass of MgO that participates, that means, we need to convert moles to grams.
To convert moles to grams we need to use molar mass of the compound:
1 atom of Mg has a molar mass of 24.3g/mol
1 atom of O has a molar mass of 16g/mol
That means molar mass of MgO is 24.3g/mol + 16g/mol = 40.3g/mol
And mass of 0.030 moles of MgO is:
0.030 moles MgO * (40.3g/mol) =
1.209g of MgO participatesPlzzzz help right answer gets a brainly!
