Convert 5 pounds to kilograms
Help me pleaseeee
Answer:
2.268
Explanation:
5 lb × 0.45359237 = 2.26796185 kg
How to convert Pounds to Kilograms
1 pound (lb) is equal to 0.45359237 kilograms (kg).
1 lb = 0.45359237 kg
The mass m in kilograms (kg) is equal to the mass m in pounds (lb) times 0.45359237:
m(kg) = m(lb) × 0.45359237
Example
Convert 5 lb to kilograms:
m(kg) = 5 lb × 0.45359237 = 2.268 kg

On a summer day in Breckenridge, Colorado, the atmospheric pressure is 525 mm Hg. What is this air pressure in West Chester, Pennsylvania as it relates to the pressure in Colorado?
a. The same as in Colorado
b. Lower than in Colorado
c. Higher than in Colorado
d. There is not enough information to tell.
Answer:
Option B
Explanation:
The atmospheric pressure in West Chester, Pennsylvania is lower than the pressure on any summer day in Breckenridge, Colorado
Colorado is 1.6 kilometers above sea level while Pennsylvania is 0.33 kilometers above sea level.
The higher a place is above sea level, the higher is the air pressure.
Hence, option B is correct
A bow and arrow that was just pulled back but not yet released has
energy.
А
potential
B
electrical
С
geothermal
nuclear
Answer:
A potential
Explanation:
potential energy is a kind of energy which rest or stays in one position
The objects rest on a position has a potential energy. The bow and arrow that was just pulled back but not yet released has energy has potential energy.
What is potential energy ?The potential energy of an object is generated by virtue of its position at height above the surface. It is the stored form of energy when the object is at rest. Whereas, kinetic energy of an object is generated by virtue of its motion.
When the object starts to move with a speed, its potential energy starts to convert into kinetic energy. Both are dependent on the mass of the object. And these energies are directly proportional to the mass.
Here, the bow and arrow are not moving with a speed they just pulled and stay on a position, so they don't have a net kinetic energy but they possess a potential energy. Hence, option A is correct.

You are asked to make 500. mL of a 0.250 M NaCl solution. How many moles of NaCl would you need?
The moles of sodium chloride we need to make 500mL solution is 0.125 mole.
What is molarity?Molarity of any solution tells about the concentration and it is define as the no. of moles of solute present in per liter of solution, and it is represented as:
M = n/V, where
M = molarity of given NaCl solution = 0.250M
V = volume of NaCl solution = 500mL = 0.5L
No we put these values on the above equation and calculate for n, we get:
n = (0.250M)(0.5L) = 0.125 mole
Hence, required moles of NaCl is 0.125 mole.

20.A molecule of sodium chloride, NaCl, consists of one atom each of sodium and chlorine. Hence, each molecule of NaCl has 2 atoms total. Similarly, we can calculate the total number of atoms in 1 mole of sodium chloride. Since 1 molecule contains 1 atom each of Na and Cl, 1 mole of NaCl will contain 1 mole each of Na and Cl.

Adaptations that help animals live in the deciduous forest biome hibernation and hard outer skin to reduce loss of water.
What is deciduous forest biomes?A deciduous forest is a type of forest which is dominatred by the trees that lose their leaves seasonally or in the growing season and Earth has dry forests.
Hibernation is a process in which plants or animals adapt themselves in order to survive in the adverse condition to conserve energy. At the same time animals will try to hard their outer skin to reduce the loss of water in the summer season.

A voltaic cell with a basic aqueous electrolyte is based on the oxidation of Cd(s) to Cd(OH)2(s) and the reduction of MnO4–(aq) to MnO2(s).
Answer:
See explanation
Explanation:
Oxidation half equation;
3Cd(s) + 6OH^-(aq) ------> 3Cd(OH)2(s) + 6e
Reduction half equation;
2MnO4^-(aq) + 8H^-(aq) + 6e --------> 2MnO2(s) + 4H2O(l)
Balanced reaction equation;
3Cd(s) + 6OH^-(aq) + 2MnO4^-(aq) + 8H^-(aq) ------> 3Cd(OH)2(s) + 2MnO2(s)

34.56 + 42.235 x 0.0123 – 0.001
with correct sig figs
Answer: 35.078 to 3 significant figures
Explanation:
Solving;
34.56 + 42.235 * 0.0123 - 0.001
We solve the multiplication first according to the BODMAS rule.
So,
42.235 * 0.0123 = 0.51949
Doing the addition,
34.56 + 0.51949 - 0.001
This gives;
35.079 - 0.001
And finally the subtraction gives;
= 35.078

Calculate the molar mass of a solute in a 1.30 L solution with of 0.50 M
containing 10.5 g of the solute.
Answer: 16 g/mol
Explanation: Molarity is Moles/Liters or Mol/L
(0.50 mol/L)(1.30L) = 0.65mol
(cancels out L)
Molar mass is g/mol so...
10.5g/0.65mol = 16.1 g/mol
Rounded to 2 sig figs is 16 g/mol

how many grams is 3.49 moles NaCl
Answer:
m = 204.16 grams
Explanation:
Given that,
No. of moles, n = 3.49
Molar mass of NaCl, M = 58.5 g/mol
We need to find the mass of 3.49 moles NaCl. We know that,
[tex]n=\dfrac{m}{M}\\\\m=n\times M\\\\m=3.49 \times 58.5\\\\m=204.16\ g[/tex]
So, there are 204.16 grams in 3.49 moles NaCl.
