Answer:
Mice
Explanation:
Small, rodent-like mammals, such as voles and mice, are the primary prey for many owl species. An owl's diet may also include frogs, lizards, snakes, fish, mice, rabbits, birds, squirrels, and other creatures. Occasionally, Great Horned Owls might even find skunks tasty enough to eat.

If you have 6.00 x 10^24 molecules of oxygen how many moles of oxygen would you have?
36.00 moles of oxygen
9.96 moles of oxygen
12.02 moles of oxygen
1.02 moles of oxygen
Answer:
9.96 moles of oxygen
Explanation:
Given data:
Number of molecule of oxygen = 6.00×10²⁴ molecules
Number of moles of oxygen = ?
Solution:
1 mole contain 6.022 ×10²³ molecules
6.00×10²⁴ molecules × 1 moles of oxygen / 6.022 ×10²³ molecules
0.996×10¹ moles of oxygen
9.96 moles of oxygen
The number 6.022 × 10²³ is called 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.

If the theoretical yield of a reaction was calculated to be 42.6 grams and when the
experiment was conducted the amount produced was 20.7 grams, the what is the percent
yield of the experiment?
Answer:
48.59%
Explanation:
theoretical yield = 42.6g
actual yield = 20.7g
% yield = 20.7/42.6 x 100 = 48.59% (2 d.p.)

What is the molal concentration of a sucrose (C12H22011) solution whose freezing point is
-2.00 °C? The Kf for water is 1.86 °C/m.
Answer: The molal concentration of sucrose solution is 1.07 m
Explanation:
Depression in freezing point is given by:
[tex]\Delta T_f=i\times K_f\times m[/tex]
[tex]\Delta T_f=T_f^0-T_f=0.00-(-2.00)^0C=2.00^0C[/tex] = Depression in freezing point
i= vant hoff factor = 1 (for non electrolyte such as sucrose)
[tex]K_f[/tex] = freezing point constant = [tex]1.86^0C/m[/tex]
m= molality
Putting in the values:
[tex]2.00^0C=1\times 1.86^0C/m\times m[/tex]
[tex]m=1.07[/tex]
Thus molal concentration of sucrose solution is 1.07 m

In a salt synthesis experiment, 13.1 g of sodium reacts with 94 g of chlorine gas, yielding 22.5 g of sodium chloride. 2Na(s) + Cl2(g) →2NaCl(s) What is the percent yield for this experiment?
Answer:
67.58%
Explanation:
First we convert the masses of the reactants into moles, using their respective molar masses:
Na ⇒ 13.1 g ÷ 23 g/mol = 0.570 molCl₂ ⇒ 94 g ÷ 70.9 g/mol = 1.32 molBy looking at the reaction equation, we know that 1.32 moles of Cl₂ would react completely with (2 * 1.32) 2.64 moles of Na. There are not as many Na moles, so Na is the limiting reactant.
Now we calculate how many NaCl moles would have been produced if all the limiting reactant was consumed:
0.570 mol Na * [tex]\frac{2molNaCl}{2molNa}[/tex]= 0.570 mol NaClWe convert those moles to grams:
0.570 mol * 58.44 g/mol = 33.31 g NaClFinally we calculate the percent yield:
22.5 g / 33.3 g * 100% = 67.58%A balloon with a volume of 4.00 L is known to contain 0.200 moles of gas. How many moles of gas remain if some of the gas is released and the new volume is 3.25 L. Assume temperature and pressure remain constant.
Please show work, thank you :D.
Explanation:
By Avagadro's Law,
V¹n¹ = V²n², where P and T are constant.
Therefore (4.00L)(0.200mol) = (3.25L)n²,
n² = 0.246mol. (3s.f.)
P.S. n² does not mean the square of n in this case, it is just a subscript.
Ideal gas law is valid only for ideal gas not for vanderwaal gas. Combined Boyle's and Charles' gas law is used here. Therefore, 0.246mol of gas remain if some of the gas is released and the new volume is 3.25 L.
What is ideal gas equation?Ideal gas equation is the mathematical expression that relates pressure volume and temperature.
Mathematically the relation between Pressure, volume and temperature can be given as
PV=nRT
where,
P = pressure of ideal gas
V= volume of ideal gas
n =number of moles of ideal gas
T =temperature of ideal gas
R = Gas constant = 0.0821 L.atm/K.mol
By Avagadro's Law,
V₁n₁= V₂n₂, where P and T are constant.
V₁×n₁= V₂×n₂,
(4.00L)(0.200mol) = (3.25L)n²
n₂ = 0.246mol.
Therefore, 0.246mol of gas remain if some of the gas is released and the new volume is 3.25 L.

What question will best help the student determine which model is plasma?
A
Which model is composed of rapidly moving particles?
B.
Which model is composed of particles vibrating in place?
C
Which model is composed of electrically charged particles?
Which model is composed of particles sliding past each other?
Answer:
C Which model is composed of electrically charged particles?
Explanation:
The best question to resolve and determine the model which is plasma is to find one that is composed of electrically charged particles.
Plasma is one of the states of matter which is characterized by ions and other charged particles.
Matter is anything that has weight and occupies space.
There are four known states of matter which are:

The _energy of the baseball is the sum of the kinetic energy and _energy of the particles that make up the baseball
Answer:
Mechanical energy
Kinetic energy
Explanation:
The mechanical energy is the sum of the kinetic and potential energy of the particles that make up the baseball.
Mechanical energy is made up of kinetic energy and potential energy. When the baseball is in motion, the particles make use of the kinetic energy, also known as motion energy and when the ball is not in motion the particles make use of the potential energy, also known as stored energy.

. In a full paragraph, tell what would you do to remove the kudzu from your property forever and what steps you will take to ensure your land and the native species on it are not being harmed. pls answer now
Efforts to control kudzu infestations have included the following methods: cutting, grazing, digging, disking, prescribed burning and application of herbicides. Roots of mature plants grow too deeply to be affected by freezing. Burning will kill only the very young plants.
Ideally, simply pulling out the heavy vines would prevent the kudzu from returning. However, you still need to kill each of the rooted stems at their crowns. Mowing or cutting back the vegetation to the ground provides the first step in removal. Then it’s time to bring out the big guns in the form of chemical herbicides.
Lead melts at 328 ℃. How much heat is required when 23.0 g of solid lead at 297 K condenses to a liquid at 702 K?
Heat = 1.74 kJ
Further explanationGiven
melts at 328 ℃ + 273 = 601 K
mass = 23 g = 0.023 kg
initial temperature = 297 K
Final tmperature = 702 K
Required
Heat
Solution
1. raise the temperature(297 to 601 K)
c of lead = 0.130 kJ/kg K
Q = 0.023 x 0.13 x (601-297)
Q = 0.909 kJ
2. phase change(solid to liquid)
Q = m.Lf (melting/freezing)
Q = 0.023 x 23 kj/kg = 0.529 kJ
3. raise the temperature(601 to 702 K)
Q = 0.023 x 0.13 x (702-601)
Q = 0.302 kJ
Total heat = 1.74 kJ
