We have that the balanced chemical equation is mathematically given as.
2Ti_3N + 3MgO → Mg_3N_2 +3Ti_2O
From the question we are told
Ti3N + MgO → Mg3N2 +Ti2O balance chemical equation.
Generally the way to balance an equation is by making all elements present on the Left hand side(LHS) same with the right hand side RHS.
Therefore
The equation is mathematically given as.
Ti_3N + MgO → Mg_3N_2 +Ti_2OWe consider the Left hand side(LHS) first.
2Ti_3N + 3MgO → Mg_3N_2 +Ti_2OThen we consider the right hand side RHS.
2Ti_3N + 3MgO → Mg_3N_2 +3Ti_2OTherefore the balanced chemical equation is mathematically given as.

a.) they count the total number of walleye eggs that a female lays each year.
b.) did you Spears to catch walleye.
c.) they only fish for walleye at night.
d.) they said a limit on the number and size of Walleye a spearfisher can catch.
The Ojibwe protected walleye populations as D. They said a limit on the number and size of Walleye a spearfisher can catch.
Wisconsin Walleye War was a series of protests regarding the fishing and hunting rights of the Ojibwes. Wisconsin wanted to regulate the rights of the people whenever they went fishing and hunting.
The protest eventually led to the state speaking to the people. This resulted in a resolution that there should be a limit on the number and size of Walleye a spearfisher can catch.
This was necessary in order to preserve the walleye for future generations.

Some thermal mugs have layers of materials to keep drinks hot for as long as possible. Which combination of layers would work best for this purpose? A. Inner core of steel, no air gap, outer layer of glass B. Inner core of steel, air gap, outer layer of plastic C. inner core of steel no air gap outer layer of glass D inner core of steel no air gap outer layer of plastic
DONT ANSWER IF U DONT KNOW DO NOT GUESS THIS IS FOR A GRADE
The best combination of layers that would work best for this purpose is an inner core of steel, no air gap, and an outer layer of glass. Option A is correct.
Thermal mugs have the ability to maintain the internal body temperature and heat of their container. For the heat to be maintained for an extended period of time. The internal core must be lined with steel because it radiates less heat compared to the glass. The steel also has high conductivity and lesser specific heat to keep drinks hot for a long period of time.
Therefore, we can conclude that for thermal mugs to keep drinks hot for as long as possible, the inner core must be lined with steel, no air gap, and contain an outer layer of glass.

Explanation:
The period of rotation of Mars is 1 day and 37 minutes. Determine its frequency of rotation in Hertz.
The frequency of rotation of Mars is 0.0000113 Hertz.
Given the following data:
Period = 1 day and 37 minutes.To find the frequency of rotation in Hertz:
First of all, we would convert the the value of period in days and minutes to seconds because the period of oscillation of a physical object is measured in seconds.
Conversion:
1 day = 24 hours
24 hours to minutes = [tex]60[/tex] × [tex]24[/tex] = [tex]1440[/tex] minutes
[tex]1440 + 37 = 1477 \; minutes[/tex]
1 minute = 60 seconds
1477 minute = X seconds
Cross-multiplying, we have:
[tex]X = 60[/tex] × [tex]1477[/tex]
X = 88620 seconds
Now, we can find the frequency of rotation of Mars by using the formula:
[tex]Frequency = \frac{1}{Period}\\\\Frequency = \frac{1}{88620}[/tex]
Frequency of rotation = 0.0000113 Hertz
Therefore, the frequency of rotation of Mars is 0.0000113 Hertz.

how can you increase the sensitivity of a Mercury thermometer?
The sensitivity of a mercury thermometer can be increased by using a smaller mercury bulb, thinner wall and smaller bore. A smaller bulb contains less mercury and hence absorbs heat in shorter time. As a result it can response faster to temperature change.

A roller coaster has a mass of 585 kg when fully loaded with passengers.
A)If the vehicle has a speed of 18.0 m/s at point a, what is the force (in N) of the track on the vehicle at this point?
B) What is the maximum speed (in m/s) the vehicle can have at point B in order for gravity to hold it on the track?
Point A says the radius is 10m. Point B says radius is 15m.
Answer:
Explanation:
I'm going to ASSUME that point A is at the bottom of a circular curve.
The track must support the weight of the car and also supply the needed centripetal force
F = mg + mv²/R
F = 585(9.81 + 18.0²/10) = 24,692.85
F = 24.7 kN
I'm going to ASSUME that point B is at the top of a circular curve.
The track must support the weight of the car and also supply the needed centripetal force.
At a minimum, the weight can be reduced to zero and all the gravity acceleration acts as centripetal acceleration.
0 = mg - mv²/R
g = v²/R
v = √Rg = √(15(9.81) = 12.1305399...

Book A with a mass of 1.00 kg is placed on a horizontal table. Book B with a mass of 0.500 kg is placed on top of book A. What is the magnitude of the normal force exerted on book A by the table?
Answer:
Explanation:
N = mg = (1.00 + 0.500)(9.81) = 14.7 N
The magnitude of the normal force exerted on book A by the table is 14.7 N
ForcesFrom the question, we are to determine the magnitude of the normal force.
The normal force ca be calculated by using the formula
[tex]F_{n} = mg[/tex]
Where [tex]F_{n}[/tex] is the normal force
m is the mass
and g is the gravitational field strength ( g = 9.8 m/s²)
The mass will be addition of the masses since Book B is placed on top of the book.
Thus,
m = 1.00 kg + 0.500 kg = 1.50 kg
Then,
[tex]F_{n} = 1.5 \times 9.8[/tex]
[tex]F_{n} = 14.7 \ N[/tex]
Hence, the magnitude of the normal force exerted on book A by the table is 14.7 N

A small heat engine has an energy input of 1,176 joules, and does 201 joules of work. What is the efficiency of the engine? (round your answer to the nearest whole number percent, but leave off the % symbol)
so, if you calculate it is 13.3%, enter your number as 13.
The efficiency of the engine is 17%.
Given the following data:
Energy input = 1,176 JoulesEnergy output = 201 JoulesTo find the efficiency of the engine:
Mathematically, the efficiency of an engine is calculated by using the formula:
[tex]Efficiency = \frac{E_O}{E_I}[/tex] × [tex]100[/tex]
Where:
Eo is the energy output.Ei is the energy input.Substituting the given parameters into the formula, we have;
[tex]Efficiency = \frac{201}{1176}[/tex] × [tex]100[/tex]
[tex]Efficiency = 0.171[/tex] × [tex]100[/tex]
Efficiency = 17%

A jet plane is traveling with a velocity of 720 kilometers/hour due north. There is a crosswind of 40 kilometers/hour from the east. Find the resultant velocity and the direction of the jet plane.
A.
720 kilometers/hour in the direction of 3.2° west of north
B.
720 kilometers/hour due north
C.
721 kilometers/hour in the direction of 3.2° west of north
D.
520 kilometers/hour in the direction of 45° east of north
Answer:
Option c is correct v = 721 km/h θ = 3.2°
Explanation:
In pic is further explanation: A triangle means division
The magnitude of the velocity of the plane can be found by calculating the resultant of the two velocities:
R= [tex]\sqrt{(720km ÷ h^)^2 + (40km ÷ h)^2) = 721.1 km ÷ h}[/tex]
The direction can be found as follows:
0 = tan^-1 (720km ÷ h/40km ÷h) = 86.8
where 720 km/h represents the velocity towards north, while 40 km/h represents the velocity towards west, so the angle is measured with respect to east. Therefore:
the direction is 86.8*north of west
